which, interestingly, does
absolutely nothing here. By default, on Windows, it opens your
browser to the Framework website and, on Linux, your "default
media player".
The keyboard backlight can be cycled with fn-space. The
dimmer version is dim enough, and the keybinding is easy to find in
the dark.
A skinny elephant would be performed with alt
PrtScr (above F11) KEY, so for
example alt fn F11 b
should do a hard reset. This comment suggests you need to hold
the fn only if "function lock" is on, but that's
actually the opposite of my experience.
Out of the box, some of the fn keys don't work. Mute,
volume up/down, brightness, monitor changes, and the airplane mode key
all do basically nothing. They don't send proper keysyms to Xorg at
all.
This is a known problem and it's related to the fact that the
laptop has light sensors to adjust the brightness
automatically. Somehow some of those keys (e.g. the brightness
controls) are supposed to show up as a different input device, but
don't seem to work correctly. It seems like the solution is for the
Framework team to write a driver specifically for this, but so far no
progress since July 2022.
In the meantime, the fancy functionality can be supposedly disabled with:
echo 'blacklist hid_sensor_hub' sudo tee /etc/modprobe.d/framework-als-blacklist.conf
... and a reboot. This solution is also documented in the upstream
guide.
Note that there's another solution flying around that fixes this by
changing permissions on the input device but I haven't tested
that or seen confirmation it works.
xbacklight
in i3, but out of the box I get
this error:

:

This way I can control the actual backlight power with the brightness
keys, and they do significantly reduce power usage.
autorandr
setup doesn't work: I have tried saving a
profile and it doesn't get autodetected, so I also first need to do:
autorandr -l framework-external-dual-lg-acer
The magic:
autorandr -l horizontal
... also works well.
The worst problem with those monitors right now is that they have a
radically smaller resolution than the main screen on the laptop, which
means I need to reset the font scaling to normal every time I switch
back and forth between those monitors and the laptop, which means I
actually need to do this:
autorandr -l horizontal &&
eho Xft.dpi: 96 xrdb -merge &&
systemctl restart terminal xcolortaillog background-image emacs &&

Kind of disruptive.

This, it turns out, was fixed in Debian lately, so a daily GRML
build will not have this problems. The upcoming 2022 release
(likely 2022.10 or 2022.11) will also get the fix.
I did manage to boot the development version of the Debian
installer which was a surprisingly good experience: it mounted the
encrypted drives and did everything pretty smoothly. It even offered
me to reinstall the boot loader, but that ultimately (and correctly, as
it turns out) failed because I didn't have a /boot/efi
partition.
At this point, I realized there was no easy way out of this, and I
just proceeded to completely reinstall Debian. I had a spare NVMe
drive lying around (backups FTW!) so I just swapped that in, rebooted
in the Debian installer, and did a clean install. I wanted to switch
to bookworm anyways, so I guess that's done too.
/etc/ssh
/var/lib/puppet
So that I would keep the previous machine's identity. That way I could
contact the Puppet server and install whatever was missing. I used my
Puppet optimization
trick to do a batch
install and then I had a good base setup, although not exactly as it
was before. 1700 packages were installed manually on angela
before
the reinstall, and not in Puppet.
I did not inspect each one individually, but I did go through /etc
and copied over more SSH keys, for backups and SMTP over SSH.

The Debian Wiki has a page on HiDPI, but it's not as good as the

Quick boot

in
the BIOS to diagnose the above boot issues. This, in turn, triggers a
bug where the BIOS boot manager (F12) would just hang
completely. It would also fail to boot from an external USB drive.
The current fix (as of BIOS 3.03) is to re-enable both Quick
boot

. Presumably this is something that will get
fixed in a future BIOS update.

(yes, after repeatedly copying a bunch more packages over to get
those bootstrapped). (Next time I should probably try something like
this post.)
Thankfully, I had a little USB-C dongle with a RJ-45 jack lying
around. That also required a firmware blob, but it was a single
package to copy over, and with that loaded, I had network.
Eventually, I did managed to make WiFi work; the problem was more on
the side of "I forgot how to configure a WPA network by hand from the
commandline" than anything else. NetworkManager worked fine and got
WiFi working correctly.
Note that this is with Debian bookworm, which has the 5.19 Linux
kernel, and with the firmware-nonfree (firmware-iwlwifi
,
specifically) package.

Summary:
System: 7.57 Watts on average with standard deviation 0.71
Expansion cards matter a lot in the battery life (see below for a
thorough discussion), my normal setup is 2xUSB-C and 1xUSB-A (yes,
with an empty slot, and yes, to save power).
Interestingly, playing a video in a (720p) window in a window takes up
more power (10.5W) than in full screen (9.5W) but I blame that on my
desktop setup (i3 + compton)... Not sure if mpv
hits the
VA-API, maybe not in windowed mode. Similar results with 1080p,
interestingly, except the window struggles to keep up altogether. Full
screen playback takes a relatively comfortable 9.5W, which means a
solid 5h+ of playback, which is fine by me.
Fooling around the web, small edits, youtube-dl
, and I'm at around 80%
battery after about an hour, with an estimated 5h left, which is a
little disappointing. I had a 7h remaining estimate before I started
goofing around Discourse, so I suspect the website is a pretty
big battery drain, actually. I see about 10-12 W, while I was probably at
half that (6-8W) just playing music with mpv
in the background...
In other words, it looks like editing posts in Discourse with Firefox
takes a solid 4-6W of power. Amazing and gross.
(When writing about abusive power usage generates more power usage, is
that an heisenbug? Or schr dinbug?)
tlp-stat -b
and, unfortunately, the "ampere"
unit makes it quite hard to compare those, because voltage is not
necessarily the same between the two platforms.

: tlp.patch.
Specifically, the kernel's energy-aware scheduling heuristics don't work well on those CPUs. A number of features present there complicate the energy picture; these include SMT, Intel's "turbo boost" mode, and the CPU's internal power-management mechanisms. For many workloads, running on an ostensibly more power-hungry Pcore can be more efficient than using an Ecore. Time for discussion of the problem was lacking, though, and the session came to a close.All this to say that the 12gen Intel line shipped with this Framework series should have better power management thanks to its power-saving cores. And Linux has had the scheduler changes to make use of this (but maybe is still having trouble). In any case, this might not be the source of power management problems on my laptop, quite the opposite. Also note that the firmware updates for various chipsets are supposed to improve things eventually. On the other hand, The Verge simply declared the whole P-series a mistake...
powertop --auto-tune
and tlp
's
PCIE_ASPM_ON_BAT=powersupersave
basically did nothing: I was stuck
at 10W power usage in powertop (600+mA in tlp-stat
).
Apparently, I should be able to reach the C8
CPU power state (or
even C9
, C10
) in powertop, but I seem to be stock at
C7
. (Although I'm not sure how to read that tab in powertop: in the
Core(HW
) column there's only C3/C6/C7 states, and most cores are 85%
in C7 or maybe C6. But the next column over does show many CPUs in
C10 states...
As it turns out, the graphics card actually takes up a good chunk of
power unless proper power management is enabled (see below). After
tweaking this, I did manage to get down to around 7W power usage in
powertop.
Expansion cards actually do take up power, and so does the screen,
obviously. The fully-lit screen takes a solid 2-3W of power compared
to the fully dimmed screen. When removing all expansion cards and
making the laptop idle, I can spin it down to 4 watts power usage at
the moment, and an amazing 2 watts when the screen turned off.

Ethernet | 1.69W | 1.64W | 1.76W | N/A | comparable to the SSD card |
It seems the USB A must have power going to it all the time, that the old USB 2 and 3 protocols, the USB C only provides power when there is a connection. Old versus new.Apparently, this is a problem specific to the USB-C to USB-A adapter that ships with the Framework. Some people have actually changed their orders to all USB-C because of this problem, but I'm not sure the problem is as serious as claimed in the forums. I couldn't reproduce the "one watt" power drains suggested elsewhere, at least not repeatedly. (A previous version of this post did show such a power drain, but it was in a less controlled test environment than the series of more rigorous tests above.) The worst offenders are the storage cards: the SSD drive takes at least one watt of power and the MicroSD card seems to want to take all the way up to 6 watts of power, both just sitting there doing nothing. This confirms claims of 1.4W for the SSD (but not 5W) power usage found elsewhere. The former post has instructions on how to disable the card in software. The MicroSD card has been reported as using 2 watts, but I've seen it as high as 6 watts, which is pretty damning. The Framework team has a beta update for the DisplayPort adapter but currently only for Windows (LVFS technically possible, "under investigation"). A USB-A firmware update is also under investigation. It is therefore likely at least some of those power management issues will eventually be fixed. Note that the upcoming Ethernet card has a reported 2-8W power usage, depending on traffic. I did my own power usage tests in powerstat-wayland and they seem lower than 2W. The upcoming 6.2 Linux kernel might also improve battery usage when idle, see this Phoronix article for details, likely in early 2023.

sep 28 11:19:45 angela systemd-sleep[209379]: /sys/class/power_supply/BAT/charge_now = 6045 [mAh]
... to this:
sep 28 11:29:47 angela systemd-sleep[209725]: /sys/class/power_supply/BAT/charge_now = 6037 [mAh]
That's 8mAh per 10 minutes (and 2 seconds), or 48mA, or, with this
battery, about 127 hours or roughly 5 days of standby. Not bad!
In comparison, here is my really old x220, before:
sep 29 22:13:54 emma systemd-sleep[176315]: /sys/class/power_supply/BAT0/energy_now = 5070 [mWh]
... after:
sep 29 22:23:54 emma systemd-sleep[176486]: /sys/class/power_supply/BAT0/energy_now = 4980 [mWh]
... which is 90 mwH in 10 minutes, or a whopping 540mA, which was
possibly okay when this battery was new (62000 mAh, so about 100
hours, or about 5 days), but this battery is almost dead and has
only 5210 mAh when full, so only 10 hours standby.
And here is the Framework performing a similar test, before:
sep 29 22:27:04 angela systemd-sleep[4515]: /sys/class/power_supply/BAT1/charge_full = 3518 [mAh]
sep 29 22:27:04 angela systemd-sleep[4515]: /sys/class/power_supply/BAT1/charge_now = 2861 [mAh]
... after:
sep 29 22:37:08 angela systemd-sleep[4743]: /sys/class/power_supply/BAT1/charge_now = 2812 [mAh]
... which is 49mAh in a little over 10 minutes (and 4 seconds), or
292mA, much more than the Purism, but half of the X220. At this rate,
the battery would last on standby only 12 hours!! That is pretty
bad.
Note that this was done with the following expansion cards:
nvme.noacpi=1
but this
still gives me about 5mAh/min (or 300mA).
Adding mem_sleep_default=deep
to the kernel command line does make a
difference. Before:
sep 29 23:03:11 angela systemd-sleep[3699]: /sys/class/power_supply/BAT1/charge_now = 2544 [mAh]
... after:
sep 29 23:04:25 angela systemd-sleep[4039]: /sys/class/power_supply/BAT1/charge_now = 2542 [mAh]
... which is 2mAh in 74 seconds, which is 97mA, brings us to a more
reasonable 36 hours, or a day and a half. It's still above the x220
power usage, and more than an order of magnitude more than the Purism
laptop. It's also far from the 0.4% promised by upstream, which
would be 14mA for the 3500mAh battery.
It should also be noted that this "deep" sleep mode is a little more
disruptive than regular sleep. As you can see by the timing, it took
more than 10 seconds for the laptop to resume, which feels a little
alarming as your banging the keyboard to bring it back to life.
You can confirm the current sleep mode with:
# cat /sys/power/mem_sleep
s2idle [deep]
In the above, deep
is selected. You can change it on the fly with:
printf s2idle > /sys/power/mem_sleep
Here's another test:
sep 30 22:25:50 angela systemd-sleep[32207]: /sys/class/power_supply/BAT1/charge_now = 1619 [mAh]
sep 30 22:31:30 angela systemd-sleep[32516]: /sys/class/power_supply/BAT1/charge_now = 1613 [mAh]
... better! 6 mAh in about 6 minutes, works out to 63.5mA, so more
than two days standby.
A longer test:
oct 01 09:22:56 angela systemd-sleep[62978]: /sys/class/power_supply/BAT1/charge_now = 3327 [mAh]
oct 01 12:47:35 angela systemd-sleep[63219]: /sys/class/power_supply/BAT1/charge_now = 3147 [mAh]
That's 180mAh in about 3.5h, 52mA! Now at 66h, or almost 3 days.
I wasn't sure why I was seeing such fluctuations in those tests, but
as it turns out, expansion card power tests show that they do
significantly affect power usage, especially the SSD drive, which can
take up to two full watts of power even when idle. I didn't control
for expansion cards in the above tests running them with whatever
card I had plugged in without paying attention so it's likely the
cause of the high power usage and fluctuations.
It might be possible to work around this problem by disabling USB
devices before suspend. TODO. See also this post.
In the meantime, I have been able to get much better suspend
performance by unplugging all modules. Then I get this result:

Which is 14.8mA! Almost exactly the number promised by Framework! With
a full battery, that means a 10 days suspend time. This is actually
pretty good, and far beyond what I was expecting when starting down
this journey.
So, once the expansion cards are unplugged, suspend power usage is
actually quite reasonable. More detailed standby tests are available
in the standby-tests page, with a summary below.
There is also some hope that the Chromebook edition
specifically designed with a specification of 14 days standby
time could bring some firmware improvements back down to the
normal line. Some of those issues were reported upstream in April
2022, but there doesn't seem to have been any progress there
since.

I looked at building this myself but failed to run it. I opened a

my work there.
Note that there is now a counter that tracks charge/discharge
cycles. It's visible in tlp-stat -b
, which is a nice
improvement:

One thing that is still missing is the charge threshold data (the

implement hysteresis support.
powertop
service which I run at boot time to tweak some power saving
settings.
It seems like this:
echo 'on' > '/sys/bus/usb/devices/4-2/power/control'
... is a good workaround to bring the card back online. You can even
return to power saving mode and the card will still work:
echo 'auto' > '/sys/bus/usb/devices/4-2/power/control'
Further research by Matt_Hartley from the Framework
Team found this issue in the tlp tracker that shows how the
USB_AUTOSUSPEND
setting enables the power saving even if the
driver doesn't support it, which, in retrospect, just sounds like a
bad idea. To quote that issue:
By default, USB power saving is active in the kernel, but not force-enabled for incompatible drivers. That is, devices that support suspension will suspend, drivers that do not, will not.So the fix is actually to uninstall
tlp
or disable that setting by
adding this to /etc/tlp.conf
:
USB_AUTOSUSPEND=0
... but that disables auto-suspend on all USB devices, which may
hurt other power usage performance. I have found that a a
combination of:
USB_AUTOSUSPEND=1
USB_DENYLIST="0bda:8156"
and this on the kernel commandline:
usbcore.quirks=0bda:8156:k
... actually does work correctly. I now have this in my
/etc/default/grub.d/framework-tweaks.cfg
file:
# net.ifnames=0: normal interface names ffs (e.g. eth0, wlan0, not wlp166
s0)
# nvme.noacpi=1: reduce SSD disk power usage (not working)
# mem_sleep_default=deep: reduce power usage during sleep (not working)
# usbcore.quirk is a workaround for the ethernet card suspend bug: https:
//guides.frame.work/Guide/Fedora+37+Installation+on+the+Framework+Laptop/
108?lang=en
GRUB_CMDLINE_LINUX="net.ifnames=0 nvme.noacpi=1 mem_sleep_default=deep usbcore.quirks=0bda:8156:k"
# fix the resolution in grub for fonts to not be tiny
GRUB_GFXMODE=1024x768
Other than that, I haven't been able to max out the card because I
don't have other 2.5Gbit/s equipment at home, which is strangely
satisfying. But running against my Turris Omnia
router, I could pretty much max a gigabit fairly easily:
[ ID] Interval Transfer Bitrate Retr
[ 5] 0.00-10.00 sec 1.09 GBytes 937 Mbits/sec 238 sender
[ 5] 0.00-10.00 sec 1.09 GBytes 934 Mbits/sec receiver
The card doesn't require any proprietary firmware blobs which is
surprising. Other than the power saving issues, it just works.
In my power tests (see powerstat-wayland), the Ethernet card seems
to use about 1.6W of power idle, without link, in the above "quirky"
configuration where the card is functional but without autosuspend.
cd /lib/firmware && rm adlp_guc_70.1.1.bin adlp_guc_69.0.3.bin
update-initramfs -u
You will get the following warning during build, which is good as
it means the problematic firmware is disabled:
W: Possible missing firmware /lib/firmware/i915/adlp_guc_69.0.3.bin for module i915
W: Possible missing firmware /lib/firmware/i915/adlp_guc_70.1.1.bin for module i915
But then it also means that critical firmware isn't loaded, which
means, among other things, a higher battery drain. I was able to move
from 8.5-10W down to the 7W range after making the firmware work
properly. This is also after turning the backlight all the way down,
as that takes a solid 2-3W in full blast.
The proper fix is to use some compositing manager. I ended up using
compton with the following systemd unit:
[Unit]
Description=start compositing manager
PartOf=graphical-session.target
ConditionHost=angela
[Service]
Type=exec
ExecStart=compton --show-all-xerrors --backend glx --vsync opengl-swc
Restart=on-failure
[Install]
RequiredBy=graphical-session.target
compton
is orphaned however, so you might be tempted to use
picom instead, but in my experience the latter uses much
more power (1-2W extra, similar experience). I also tried
compiz
but it would just crash with:
anarcat@angela:~$ compiz --replace
compiz (core) - Warn: No XI2 extension
compiz (core) - Error: Another composite manager is already running on screen: 0
compiz (core) - Fatal: No manageable screens found on display :0
When running from the base session, I would get this instead:
compiz (core) - Warn: No XI2 extension
compiz (core) - Error: Couldn't load plugin 'ccp'
compiz (core) - Error: Couldn't load plugin 'ccp'
Thanks to EmanueleRocca for figuring all that out. See also this
discussion about power management on the Framework forum.
Note that Wayland environments do not require any special
configuration here and actually work better, see my Wayland migration
notes for details.

Some of those are available in the latest upstream firmware package
(iwlwifi-ty-a0-gf-a0-71.ucode
, -68
, and -67
), but not all
(e.g. iwlwifi-ty-a0-gf-a0-72.ucode
is missing) . It's unclear what
those do or don't, as the WiFi seems to work well without them.
I still copied them in from the latest linux-firmware package in the
hope they would help with power management, but I did not notice a
change after loading them.
There are also multiple knobs on the iwlwifi
and iwlmvm
drivers. The latter has a power_schmeme
setting which defaults to
2
(balanced
), setting it to 3
(low power
) could improve
battery usage as well, in theory. The iwlwifi
driver also has
power_save
(defaults to disabled) and power_level
(1-5, defaults
to 1
) settings. See also the output of modinfo iwlwifi
and
modinfo iwlmvm
for other driver options.
compton
, above), I tested the classic
glxgears
.
Running in a window gives me odd results, as the gears basically grind
to a halt:
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
137 frames in 5.1 seconds = 26.984 FPS
27 frames in 5.4 seconds = 5.022 FPS
Ouch. 5FPS!
But interestingly, once the window is in full screen, it does hit the
monitor refresh rate:
300 frames in 5.0 seconds = 60.000 FPS
I'm not really a gamer and I'm not normally using any of that fancy
graphics acceleration stuff (except maybe my browser does?).
I installed intel-gpu-tools for the intel_gpu_top
command to confirm the GPU was engaged when doing those simulations. A
nice find. Other useful diagnostic tools include glxgears
and
glxinfo
(in mesa-utils) and (vainfo
in vainfo).
Following to this post, I also made sure to have those settings
in my about:config
in Firefox, or, in user.js
:
user_pref("media.ffmpeg.vaapi.enabled", true);
Note that the guide suggests many other settings to tweak, but those
might actually be overkill, see this comment and its parents. I
did try forcing hardware acceleration by setting gfx.webrender.all
to true
, but everything became choppy and weird.
The guide also mentions installing the intel-media-driver
package,
but I could not find that in Debian.
The Arch wiki has, as usual, an excellent reference on hardware
acceleration in Firefox.
~/.config/chromium-flags.conf
but that doesn't actually work in
Debian. I had to put the flag in
/etc/chromium.d/disable-compositing
, like this:
export CHROMIUM_FLAGS="$CHROMIUM_FLAGS --disable-gpu-compositing"
It's possible another one of the hundreds of flags might fix this
issue better, but I don't really have time to go through this entire,
incomplete, and unofficial list (!?!).
Signal Desktop is a similar problem, and doesn't reuse those flags
(because of course it doesn't). Instead I had to rewrite the wrapper
script in /usr/local/bin/signal-desktop
to use this instead:
exec /usr/bin/flatpak run --branch=stable --arch=x86_64 org.signal.Signal --disable-gpu-compositing "$@"
This was mostly done in this Puppet commit.
I haven't figured out the root of this problem. I did try using
picom
and xcompmgr
; they both suffer from the same issue. Another
Debian testing user on Wayland told me they haven't seen this problem,
so hopefully this can be fixed by switching to
wayland.

It's a solid 30 seconds graphical hang. Maybe the keyboard and
everything else keeps working. The latter bug report is quite long,
with many comments, but this one from January 2023 seems to say
that Sway 1.8 fixed the problem. There's also an earlier patch to
add an extra kernel parameter that supposedly fixes that too. There's
all sorts of other workarounds in there, for example this:
echo "options i915 enable_dc=1 enable_guc_loading=1 enable_guc_submission=1 edp_vswing=0 enable_guc=2 enable_fbc=1 enable_psr=1 disable_power_well=0" sudo tee /etc/modprobe.d/i915.conf
from this comment... So that one is unsolved, as far as the
upstream drivers are concerned, but maybe could be fixed through Sway.

and act as a client to the others. See below.Peers
to something like Peers: ["tls://routernode:12345"]
where routernode
is the Docker hostname of the router container, and 12345 is its port number as defined above. If you have more than one local router container, you can simply list them all here. Yggdrasil will then fail over nicely if any one of them go down.Listen
should be empty.MulticastInterfaces
should be empty.ping6
between your containers. If you have multiple hosts running Docker, you can simply set up the router nodes on each to connect to each other. Now you have direct, secure, container-to-container communication that is host-agnostic! You can also set up Yggdrasil on a bare metal server or VM using standard procedures and everything will just talk nicely!
AllowedPublicKeys
on the nodes with listening ports, you can authenticate the Yggdrasil peers. Note that part of the benefit of the Yggdrasil mesh is normally that you don t have to propagate a configuration change to every participatory node that s a nice thing in general!
You can also run a firewall inside your container (I like firehol
for this purpose) and aggressively firewall the IPs that are allowed to connect via the Yggdrasil interface. I like to set a stable interface name like ygg0
in yggdrasil.conf
, and then it becomes pretty easy to firewall the services. The Docker parameters that allow Yggdrasil to run are also sufficient to run firehol.

The Great War and Modern Memory (1975)
Wartime: Understanding and Behavior in the Second World War (1989)
Paul Fussell
Rather than describe the battles, weapons, geopolitics or big personalities of the two World Wars, Paul Fussell's The Great War and Modern Memory & Wartime are focused instead on how the two wars have been remembered by their everyday participants. Drawing on the memoirs and memories of soldiers and civilians along with a brief comparison with the actual events that shaped them, Fussell's two books are a compassionate, insightful and moving piece of analysis.
Fussell primarily sets himself against the admixture of nostalgia and trauma that obscures the origins and unimaginable experience of participating in these wars; two wars that were, in his view, a "perceptual and rhetorical scandal from which total recovery is unlikely." He takes particular aim at the dishonesty of hindsight:
For the past fifty years, the Allied war has been sanitised and romanticised almost beyond recognition by the sentimental, the loony patriotic, the ignorant and the bloodthirsty. I have tried to balance the scales. [And] in unbombed America especially, the meaning of the war [seems] inaccessible.The author does not engage in any of the customary rose-tinted view of war, yet he remains understanding and compassionate towards those who try to locate a reason within what was quite often senseless barbarism. If anything, his despondency and pessimism about the Second World War (the war that Fussell himself fought in) shines through quite acutely, and this is especially the case in what he chooses to quote from others:
"It was common [ ] throughout the [Okinawa] campaign for replacements to get hit before we even knew their names. They came up confused, frightened, and hopeful, got wounded or killed, and went right back to the rear on the route by which they had come, shocked, bleeding, or stiff. They were forlorn figures coming up to the meat grinder and going right back out of it like homeless waifs, unknown and faceless to us, like unread books on a shelf."It would take a rather heartless reader to fail to be sobered by this final simile, and an even colder one to view Fussell's citation of such an emotive anecdote to be manipulative. Still, stories and cruel ironies like this one infuse this often-angry book, but it is not without astute and shrewd analysis as well, especially on the many qualitative differences between the two conflicts that simply cannot be captured by facts and figures alone. For example:
A measure of the psychological distance of the Second [World] War from the First is the rarity, in 1914 1918, of drinking and drunkenness poems.Indeed so. In fact, what makes Fussell's project so compelling and perhaps even unique is that he uses these non-quantitive measures to try and take stock of what happened. After all, this was a war conducted by humans, not the abstract school of statistics. And what is the value of a list of armaments destroyed by such-and-such a regiment when compared with truly consequential insights into both how the war affected, say, the psychology of postwar literature ("Prolonged trench warfare, whether enacted or remembered, fosters paranoid melodrama, which I take to be a primary mode in modern writing."), the specific words adopted by combatants ("It is a truism of military propaganda that monosyllabic enemies are easier to despise than others") as well as the very grammar of interaction:
The Field Service Post Card [in WW1] has the honour of being the first widespread exemplary of that kind of document which uniquely characterises the modern world: the "Form". [And] as the first widely known example of dehumanised, automated communication, the post card popularised a mode of rhetoric indispensable to the conduct of later wars fought by great faceless conscripted armies.And this wouldn't be a book review without argument-ending observations that:
Indicative of the German wartime conception [of victory] would be Hitler and Speer's elaborate plans for the ultimate reconstruction of Berlin, which made no provision for a library.Our myths about the two world wars possess an undisputed power, in part because they contain an essential truth the atrocities committed by Germany and its allies were not merely extreme or revolting, but their full dimensions (embodied in the Holocaust and the Holodomor) remain essentially inaccessible within our current ideological framework. Yet the two wars are better understood as an abyss in which we were all dragged into the depths of moral depravity, rather than a battle pitched by the forces of light against the forces of darkness. Fussell is one of the few observers that can truly accept and understand this truth and is still able to speak to us cogently on the topic from the vantage point of experience. The Second World War which looms so large in our contemporary understanding of the modern world (see below) may have been necessary and unavoidable, but Fussell convinces his reader that it was morally complicated "beyond the power of any literary or philosophic analysis to suggest," and that the only way to maintain a na ve belief in the myth that these wars were a Manichaean fight between good and evil is to overlook reality. There are many texts on the two World Wars that can either stir the intellect or move the emotions, but Fussell's two books do both. A uniquely perceptive and intelligent commentary; outstanding.
Longitude (1995) Dava Sobel Since Man first decided to sail the oceans, knowing one's location has always been critical. Yet doing so reliably used to be a serious problem if you didn't know where you were, you are far more likely to die and/or lose your valuable cargo. But whilst finding one's latitude (ie. your north south position) had effectively been solved by the beginning of the 17th century, finding one's (east west) longitude was far from trustworthy in comparison. This book first published in 1995 is therefore something of an anachronism. As in, we readily use the GPS facilities of our phones today without hesitation, so we find it difficult to imagine a reality in which knowing something fundamental like your own location is essentially unthinkable. It became clear in the 18th century, though, that in order to accurately determine one's longitude, what you actually needed was an accurate clock. In Longitude, therefore, we read of the remarkable story of John Harrison and his quest to create a timepiece that would not only keep time during a long sea voyage but would survive the rough ocean conditions as well. Self-educated and a carpenter by trade, Harrison made a number of important breakthroughs in keeping accurate time at sea, and Longitude describes his novel breakthroughs in a way that is both engaging and without talking down to the reader. Still, this book covers much more than that, including the development of accurate longitude going hand-in-hand with advancements in cartography as well as in scientific experiments to determine the speed of light: experiments that led to the formulation of quantum mechanics. It also outlines the work being done by Harrison's competitors. 'Competitors' is indeed the correct word here, as Parliament offered a huge prize to whoever could create such a device, and the ramifications of this tremendous financial incentive are an essential part of this story. For the most part, though, Longitude sticks to the story of Harrison and his evolving obsession with his creating the perfect timepiece. Indeed, one reason that Longitude is so resonant with readers is that many of the tropes of the archetypical 'English inventor' are embedded within Harrison himself. That is to say, here is a self-made man pushing against the establishment of the time, with his groundbreaking ideas being underappreciated in his life, or dishonestly purloined by his intellectual inferiors. At the level of allegory, then, I am minded to interpret this portrait of Harrison as a symbolic distillation of postwar Britain a nation acutely embarrassed by the loss of the Empire that is now repositioning itself as a resourceful but plucky underdog; a country that, with a combination of the brains of boffins and a healthy dose of charisma and PR, can still keep up with the big boys. (It is this same search for postimperial meaning I find in the fiction of John le Carr , and, far more famously, in the James Bond franchise.) All of this is left to the reader, of course, as what makes Longitute singularly compelling is its gentle manner and tone. Indeed, at times it was as if the doyenne of sci-fi Ursula K. LeGuin had a sideline in popular non-fiction. I realise it's a mark of critical distinction to downgrade the importance of popular science in favour of erudite academic texts, but Latitude is ample evidence that so-called 'pop' science need not be patronising or reductive at all.
Closed Chambers: The Rise, Fall, and Future of the Modern Supreme Court (1998) Edward Lazarus After the landmark decision by the U.S. Supreme Court in *Dobbs v. Jackson Women's Health Organization that ended the Constitutional right to abortion conferred by Roe v Wade, I prioritised a few books in the queue about the judicial branch of the United States. One of these books was Closed Chambers, which attempts to assay, according to its subtitle, "The Rise, Fall and Future of the Modern Supreme Court". This book is not merely simply a learned guide to the history and functioning of the Court (although it is completely creditable in this respect); it's actually an 'insider' view of the workings of the institution as Lazurus was a clerk for Justice Harry Blackmun during the October term of 1988. Lazarus has therefore combined his experience as a clerk and his personal reflections (along with a substantial body of subsequent research) in order to communicate the collapse in comity between the Justices. Part of this book is therefore a pure history of the Court, detailing its important nineteenth-century judgements (such as Dred Scott which ruled that the Constitution did not consider Blacks to be citizens; and Plessy v. Ferguson which failed to find protection in the Constitution against racial segregation laws), as well as many twentieth-century cases that touch on the rather technical principle of substantive due process. Other layers of Lazurus' book are explicitly opinionated, however, and they capture the author's assessment of the Court's actions in the past and present [1998] day. Given the role in which he served at the Court, particular attention is given by Lazarus to the function of its clerks. These are revealed as being far more than the mere amanuenses they were hitherto believed to be. Indeed, the book is potentially unique in its the claim that the clerks have played a pivotal role in the deliberations, machinations and eventual rulings of the Court. By implication, then, the clerks have plaedy a crucial role in the internal controversies that surround many of the high-profile Supreme Court decisions decisions that, to the outsider at least, are presented as disinterested interpretations of Constitution of the United States. This is of especial importance given that, to Lazarus, "for all the attention we now pay to it, the Court remains shrouded in confusion and misunderstanding." Throughout his book, Lazarus complicates the commonplace view that the Court is divided into two simple right vs. left political factions, and instead documents an ever-evolving series of loosely held but strongly felt series of cabals, quid pro quo exchanges, outright equivocation and pure personal prejudices. (The age and concomitant illnesses of the Justices also appears to have a not insignificant effect on the Court's rulings as well.) In other words, Closed Chambers is not a book that will be read in a typical civics class in America, and the only time the book resorts to the customary breathless rhetoric about the US federal government is in its opening chapter:
The Court itself, a Greek-style temple commanding the crest of Capitol Hill, loomed above them in the dim light of the storm. Set atop a broad marble plaza and thirty-six steps, the Court stands in splendid isolation appropriate to its place at the pinnacle of the national judiciary, one of the three independent and "coequal" branches of American government. Once dubbed the Ivory Tower by architecture critics, the Court has a Corinthian colonnade and massive twenty-foot-high bronze doors that guard the single most powerful judicial institution in the Western world. Lights still shone in several offices to the right of the Court's entrance, and [ ]Et cetera, et cetera. But, of course, this encomium to the inherent 'nobility' of the Supreme Court is quickly revealed to be a narrative foil, as Lazarus soon razes this dangerously na ve conception to the ground:
[The] institution is [now] broken into unyielding factions that have largely given up on a meaningful exchange of their respective views or, for that matter, a meaningful explication or defense of their own views. It is of Justices who in many important cases resort to transparently deceitful and hypocritical arguments and factual distortions as they discard judicial philosophy and consistent interpretation in favor of bottom-line results. This is a Court so badly splintered, yet so intent on lawmaking, that shifting 5-4 majorities, or even mere pluralities, rewrite whole swaths of constitutional law on the authority of a single, often idiosyncratic vote. It is also a Court where Justices yield great and excessive power to immature, ideologically driven clerks, who in turn use that power to manipulate their bosses and the institution they ostensibly serve.Lazurus does not put forward a single, overarching thesis, but in the final chapters, he does suggest a potential future for the Court:
In the short run, the cure for what ails the Court lies solely with the Justices. It is their duty, under the shield of life tenure, to recognize the pathologies affecting their work and to restore the vitality of American constitutionalism. Ultimately, though, the long-term health of the Court depends on our own resolve on whom [we] select to join that institution.Back in 1998, Lazurus might have had room for this qualified optimism. But from the vantage point of 2022, it appears that the "resolve" of the United States citizenry was not muscular enough to meet his challenge. After all, Lazurus was writing before Bush v. Gore in 2000, which arrogated to the judicial branch the ability to decide a presidential election; the disillusionment of Barack Obama's failure to nominate a replacement for Scalia; and many other missteps in the Court as well. All of which have now been compounded by the Trump administration's appointment of three Republican-friendly justices to the Court, including hypocritically appointing Justice Barrett a mere 38 days before the 2020 election. And, of course, the leaking and ruling in Dobbs v. Jackson, the true extent of which has not been yet. Not of a bit of this is Lazarus' fault, of course, but the Court's recent decisions (as well as the liberal hagiographies of 'RBG') most perforce affect one's reading of the concluding chapters. The other slight defect of Closed Chambers is that, whilst it often implies the importance of the federal and state courts within the judiciary, it only briefly positions the Supreme Court's decisions in relation to what was happening in the House, Senate and White House at the time. This seems to be increasingly relevant as time goes on: after all, it seems fairly clear even to this Brit that relying on an activist Supreme Court to enact progressive laws must be interpreted as a failure of the legislative branch to overcome the perennial problems of the filibuster, culture wars and partisan bickering. Nevertheless, Lazarus' book is in equal parts ambitious, opinionated, scholarly and dare I admit it? wonderfully gossipy. By juxtaposing history, memoir, and analysis, Closed Chambers combines an exacting evaluation of the Court's decisions with a lively portrait of the intellectual and emotional intensity that has grown within the Supreme Court's pseudo-monastic environment all while it struggles with the most impactful legal issues of the day. This book is an excellent and well-written achievement that will likely never be repeated, and a must-read for anyone interested in this ever-increasingly important branch of the US government.
Crashed: How a Decade of Financial Crises Changed the World (2018)
Shutdown: How Covid Shook the World's Economy (2021)
Adam Tooze
The economic historian Adam Tooze has often been labelled as an unlikely celebrity, but in the fourteen years since the global financial crisis of 2008, a growing audience has been looking for answers about the various failures of the modern economy. Tooze, a professor of history at New York's Columbia University, has written much that is penetrative and thought-provoking on this topic, and as a result, he has generated something of a cult following amongst economists, historians and the online left.
I actually read two Tooze books this year. The first, Crashed (2018), catalogues the scale of government intervention required to prop up global finance after the 2008 financial crisis, and it characterises the different ways that countries around the world failed to live up to the situation, such as doing far too little, or taking action far too late. The connections between the high-risk subprime loans, credit default swaps and the resulting liquidity crisis in the US in late 2008 is fairly well known today in part thanks to films such as Adam McKay's 2015 The Big Short and much improved economic literacy in media reportage. But Crashed makes the implicit claim that, whilst the specific and structural origins of the 2008 crisis are worth scrutinising in exacting detail, it is the reaction of states in the months and years after the crash that has been overlooked as a result.
After all, this is a reaction that has not only shaped a new economic order, it has created one that does not fit any conventional idea about the way the world 'ought' to be run. Tooze connects the original American banking crisis to the (multiple) European debt crises with a larger crisis of liberalism. Indeed, Tooze somehow manages to cover all these topics and more, weaving in Trump, Brexit and Russia's 2014 annexation of Crimea, as well as the evolving role of China in the post-2008 economic order.
Where Crashed focused on the constellation of consequences that followed the events of 2008, Shutdown is a clear and comprehensive account of the way the world responded to the economic impact of Covid-19. The figures are often jaw-dropping: soon after the disease spread around the world, 95% of the world's economies contracted simultaneously, and at one point, the global economy shrunk by approximately 20%. Tooze's keen and sobering analysis of what happened is made all the more remarkable by the fact that it came out whilst the pandemic was still unfolding. In fact, this leads quickly to one of the book's few flaws: by being published so quickly, Shutdown prematurely over-praises China's 'zero Covid' policy, and these remarks will make a reader today squirm in their chair. Still, despite the regularity of these references (after all, mentioning China is very useful when one is directly comparing economic figures in early 2021, for examples), these are actually minor blemishes on the book's overall thesis.
That is to say, Crashed is not merely a retelling of what happened in such-and-such a country during the pandemic; it offers in effect a prediction about what might be coming next. Whilst the economic responses to Covid averted what could easily have been another Great Depression (and thus showed it had learned some lessons from 2008), it had only done so by truly discarding the economic rule book. The by-product of inverting this set of written and unwritten conventions that have governed the world for the past 50 years, this 'Washington consensus' if you well, has yet to be fully felt.
Of course, there are many parallels between these two books by Tooze. Both the liquidity crisis outlined in Crashed and the economic response to Covid in Shutdown exposed the fact that one of the central tenets of the modern economy ie. that financial markets can be trusted to regulate themselves was entirely untrue, and likely was false from the very beginning. And whilst Adam Tooze does not offer a singular piercing insight (conveying a sense of rigorous mastery instead), he may as well be asking whether we're simply going to lurch along from one crisis to the next, relying on the technocrats in power to fix problems when everything blows up again. The answer may very well be yes.
Looking for the Good War: American Amnesia and the Violent Pursuit of Happiness (2021) Elizabeth D. Samet Elizabeth D. Samet's Looking for the Good War answers the following question what would be the result if you asked a professor of English to disentangle the complex mythology we have about WW2 in the context of the recent US exit of Afghanistan? Samet's book acts as a twenty-first-century update of a kind to Paul Fussell's two books (reviewed above), as well as a deeper meditation on the idea that each new war is seen through the lens of the previous one. Indeed, like The Great War and Modern Memory (1975) and Wartime (1989), Samet's book is a perceptive work of demystification, but whilst Fussell seems to have been inspired by his own traumatic war experience, Samet is not only informed by her teaching West Point military cadets but by the physical and ontological wars that have occurred during her own life as well. A more scholarly and dispassionate text is the result of Samet's relative distance from armed combat, but it doesn't mean Looking for the Good War lacks energy or inspiration. Samet shares John Adams' belief that no political project can entirely shed the innate corruptions of power and ambition and so it is crucial to analyse and re-analyse the role of WW2 in contemporary American life. She is surely correct that the Second World War has been universally elevated as a special, 'good' war. Even those with exceptionally giddy minds seem to treat WW2 as hallowed:
It is nevertheless telling that one of the few occasions to which Trump responded with any kind of restraint while he was in office was the 75th anniversary of D-Day in 2019.What is the source of this restraint, and what has nurtured its growth in the eight decades since WW2 began? Samet posits several reasons for this, including the fact that almost all of the media about the Second World War is not only suffused with symbolism and nostalgia but, less obviously, it has been made by people who have no experience of the events that they depict. Take Stephen Ambrose, author of Steven Spielberg's Band of Brothers miniseries: "I was 10 years old when the war ended," Samet quotes of Ambrose. "I thought the returning veterans were giants who had saved the world from barbarism. I still think so. I remain a hero worshiper." If Looking for the Good War has a primary thesis, then, it is that childhood hero worship is no basis for a system of government, let alone a crusading foreign policy. There is a straight line (to quote this book's subtitle) from the "American Amnesia" that obscures the reality of war to the "Violent Pursuit of Happiness." Samet's book doesn't merely just provide a modern appendix to Fussell's two works, however, as it adds further layers and dimensions he overlooked. For example, Samet provides some excellent insight on the role of Western, gangster and superhero movies, and she is especially good when looking at noir films as a kind of kaleidoscopic response to the Second World War:
Noir is a world ruled by bad decisions but also by bad timing. Chance, which plays such a pivotal role in war, bleeds into this world, too.Samet rightfully weaves the role of women into the narrative as well. Women in film noir are often celebrated as 'independent' and sassy, correctly reflecting their newly-found independence gained during WW2. But these 'liberated' roles are not exactly a ringing endorsement of this independence: the 'femme fatale' and the 'tart', etc., reflect a kind of conditional freedom permitted to women by a post-War culture which is still wedded to an outmoded honour culture. In effect, far from being novel and subversive, these roles for women actually underwrote the ambient cultural disapproval of women's presence in the workforce. Samet later connects this highly-conditional independence with the liberation of Afghan women, which:
is inarguably one of the more palatable outcomes of our invasion, and the protection of women's rights has been invoked on the right and the left as an argument for staying the course in Afghanistan. How easily consequence is becoming justification. How flattering it will be one day to reimagine it as original objective.Samet has ensured her book has a predominantly US angle as well, for she ends her book with a chapter on the pseudohistorical Lost Cause of the Civil War. The legacy of the Civil War is still visible in the physical phenomena of Confederate statues, but it also exists in deep-rooted racial injustice that has been shrouded in euphemism and other psychological devices for over 150 years. Samet believes that a key part of what drives the American mythology about the Second World War is the way in which it subconsciously cleanses the horrors of brother-on-brother murder that were seen in the Civil War. This is a book that is not only of interest to historians of the Second World War; it is a work for anyone who wishes to understand almost any American historical event, social issue, politician or movie that has appeared since the end of WW2. That is for better or worse everyone on earth.

$ kubectl apply -f deploy.yamlBack in the viz dashboard, I do see the workload deployed, but it isn t currently communicating with the Linkerd control plane, and so doesn t show any metrics, and the Meshed count is 0:Looking at the Pod s deployment YAML, I can see that it only includes the nginx container:
$ kubectl get pod nginx-deployment-cd55c47f5-cgxw2 -o yamlLet s directly inject the linkerd data plane into this running container. We do this by retrieving the YAML of the deployment, piping it to linkerd cli to inject the necessary components and then piping to kubectl apply the changed resources.

$ kubectl get deploy nginx-deployment -o yaml linkerd inject - kubectl apply -f -
deployment "nginx-deployment" injected
deployment.apps/nginx-deployment configuredBack in the viz dashboard, the workload now is integrated into Linkerd control plane.Looking at the updated Pod definition, we see a number of changes that the linkerd has injected that allows it to integrate with the control plane. Let s have a look:
$ kubectl get pod nginx-deployment-858bdd545b-55jpf -o yamlAt this point, the necessary components are setup for you to explore Linkerd further. You can also try out the jaeger and multicluster extensions, similar to the process of installing and using the viz extension and try out their capabilities.Inject Linkerd data plane automaticallyIn this approach, we shall we how to instruct Kubernetes to automatically inject the Linkerd data plane to workloads at deployment time.We can achieve this by adding the linkerd.io/inject annotation to the deployment descriptor which causes the proxy injector admission hook to execute and inject linkerd data plane components automatically at the time of deployment.

$ cat deploy.yamlThis annotation can also be specified at the namespace level to affect all the workloads within the namespace. Note that any resources created before the annotation was added to the namespace will require a rollout restart to trigger the injection of the Linkerd components.Uninstalling LinkerdNow that we have walked through the installation and setup process of Linkerd, let s also cover how to remove it from the infrastructure and go back to the state prior to its installation.The first step would be to remove extensions, such as viz.

Jrdrecovery
. It ll error on finding /cache/update.zip
and wipe the main partition anyway. That ll leave you in a boot loop where the device boots the recovery partition which tries to install /cache/update.zip
which of course still doesn t exist.
So. Where next? First, I need to get the device into a state where I can actually do something other than watch it boot into recovery, fail to flash and reboot. Best guess at present is to try and get it to enter the Qualcomm EDL (Emergency Download) mode. That might be possible with a custom USB cable that grounds D+ on boot. Alternatively I need to probe some of the other test points on the PCB and see if grounding any of those helps enter EDL mode. I then need a suitable firehose OEM-signed programmer image. And then I need to actually get hold of a proper EE40VB firmware image, either via one of the OTA update files or possibly via an Alcatel ADSU image (though no idea how to get hold of one, other than by posting to a random GSM device forum and hoping for the kindness of strangers). More updates if/when I make progress

"It's Groundhog Day," said Max. "The new people come in and think that the previous administration and the civil service are lazy or stupid. Then they actually get to know the place they are managing. And when they leave, they say, 'This was a really hard job, and those are the best people I've ever worked with.' This happens over and over and over."By 2016, Stier saw vast improvements, despite his frustration with other actions of the Obama administration. He believed their transition briefings were one of the best courses ever produced on how the federal government works. Then that transition process ran into Donald Trump. Or, to be more accurate, that transition did not run into Donald Trump, because neither he nor anyone who worked for him were there. We'll never know how good the transition information was because no one ever listened to or read it. Meetings were never scheduled. No one showed up. This book is not truly about the presidential transition, though, despite its presence as a continuing theme. The Fifth Risk is, at its heart, an examination of government work, the people who do it, why it matters, and why you should care about it. It's a study of the surprising and misunderstood responsibilities of the departments of the United States federal government. And it's a series of profiles of the people who choose this work as a career, not in the upper offices of political appointees, but deep in the civil service, attempting to keep that system running. I will warn now that I am far too happy that this book exists to be entirely objective about it. The United States desperately needs basic education about the government at all levels, but particularly the federal civil service. The public impression of government employees is skewed heavily towards the small number of public-facing positions and towards paperwork frustrations, over which the agency usually has no control because they have been sabotaged by Congress (mostly by Republicans, although the Democrats get involved occasionally). Mental images of who works for the government are weirdly selective. The Coast Guard could say "I'm from the government and I'm here to help" every day, to the immense gratitude of the people they rescue, but Reagan was still able to use that as a cheap applause line in his attack on government programs. Other countries have more functional and realistic social attitudes towards their government workers. The United States is trapped in a politically-fueled cycle of contempt and ignorance. It has to stop. And one way to help stop it is someone with Michael Lewis's story-telling skills writing a different narrative. The Fifth Risk is divided into a prologue about presidential transitions, three main parts, and an afterword (added in current editions) about a remarkable government worker whom you likely otherwise would never hear about. Each of the main parts talks about a different federal department: the Department of Energy, the Department of Agriculture, and the Department of Commerce. In keeping with the theme of the book, the people Lewis profiles do not do what you might expect from the names of those departments. Lewis's title comes from his discussion with John MacWilliams, a former Goldman Sachs banker who quit the industry in search of more personally meaningful work and became the chief risk officer for the Department of Energy. Lewis asks him for the top five risks he sees, and if you know that the DOE is responsible for safeguarding nuclear weapons, you will be able to guess several of them: nuclear weapons accidents, North Korea, and Iran. If you work in computer security, you may share his worry about the safety of the electrical grid. But his fifth risk was project management. Can the government follow through on long-term hazardous waste safety and cleanup projects, despite constant political turnover? Can it attract new scientists to the work of nuclear non-proliferation before everyone with the needed skills retires? Can it continue to lay the groundwork with basic science for innovation that we'll need in twenty or fifty years? This is what the Department of Energy is trying to do. Lewis's profiles of other departments are similarly illuminating. The Department of Agriculture is responsible for food stamps, the most effective anti-poverty program in the United States with the possible exception of Social Security. The section on the Department of Commerce is about weather forecasting, specifically about NOAA (the National Oceanic and Atmospheric Administration). If you didn't know that all of the raw data and many of the forecasts you get from weather apps and web sites are the work of government employees, and that AccuWeather has lobbied Congress persistently for years to prohibit the NOAA from making their weather forecasts public so that AccuWeather can charge you more for data your taxes already paid for, you should read this book. The story of American contempt for government work is partly about ignorance, but it's also partly about corporations who claim all of the credit while selling taxpayer-funded resources back to you at absurd markups. The afterword I'll leave for you to read for yourself, but it's the story of Art Allen, a government employee you likely have never heard of but whose work for the Coast Guard has saved more lives than we are able to measure. I found it deeply moving. If you, like I, are a regular reader of long-form journalism and watch for new Michael Lewis essays in particular, you've probably already read long sections of this book. By the time I sat down with it, I think I'd read about a third in other forms on-line. But the profiles that I had already read were so good that I was happy to read them again, and the additional stories and elaboration around previously published material was more than worth the cost and time investment in the full book.
It was never obvious to me that anyone would want to read what had interested me about the United States government. Doug Stumpf, my magazine editor for the past decade, persuaded me that, at this strange moment in American history, others might share my enthusiasm.I'll join Michael Lewis in thanking Doug Stumpf. The Fifth Risk is not a proposal for how to fix government, or politics, or polarization. It's not even truly a book about the Trump presidency or about the transition. Lewis's goal is more basic: The United States government is full of hard-working people who are doing good and important work. They have effectively no public relations department. Achievements that would result in internal and external press releases in corporations, not to mention bonuses and promotions, go unnoticed and uncelebrated. If you are a United States citizen, this is your government and it does important work that you should care about. It deserves the respect of understanding and thoughtful engagement, both from the citizenry and from the politicians we elect. Rating: 10 out of 10

What many black women were angry about was how I located myself in what I'd written. I said, blithely as a matter of observable fact, that I am unattractive. Because I am unattractive, the argument went, I have a particular kind of experience of beauty, race, racism, and interacting with what we might call the white gaze. I thought nothing of it at the time I was writing it, which is unusual. I can usually pinpoint what I have said, written, or done that will piss people off and which people will be pissed off. I missed this one entirely.What follows is one of the best essays on the social construction of beauty I've ever read. It barely pauses at the typical discussion of unrealistic beauty standards as a feminist issue, instead diving directly into beauty as whiteness, distinguishing between beauty standards that change with generations and the more lasting rules that instead police the bounds between white and not white. McMillan Cottom then goes on to explain how beauty is a form of capital, a poor and problematic one but nonetheless one of the few forms of capital women have access to, and therefore why black women have fought to be included in beauty despite all of the problems with judging people by beauty standards. And the essay deepens from there into a trenchant critique of both capitalism and white feminism that is both precise and illuminating.
When I say that I am unattractive or ugly, I am not internalizing the dominant culture's assessment of me. I am naming what has been done to me. And signaling who did it. I am glad that doing so unsettles folks, including the many white women who wrote to me with impassioned cases for how beautiful I am. They offered me neoliberal self-help nonsense that borders on the religious. They need me to believe beauty is both achievable and individual, because the alternative makes them vulnerable.I could go on. Every essay in this book deserves similar attention. I want to quote from all of them. These essays are about racism, feminism, capitalism, and economics, all at the same time. They're about power, and how it functions in society, and what it does to people. There is an essay about Obama that contains the most concise explanation for his appeal to white voters that I've read. There is a fascinating essay about the difference between ethnic black and black-black in U.S. culture. There is so much more.
We do not share much in the U.S. culture of individualism except our delusions about meritocracy. God help my people, but I can talk to hundreds of black folks who have been systematically separated from their money, citizenship, and personhood and hear at least eighty stories about how no one is to blame but themselves. That is not about black people being black but about people being American. That is what we do. If my work is about anything it is about making plain precisely how prestige, money, and power structure our so-called democratic institutions so that most of us will always fail.I, like many other people in my profession, was always more comfortable with the technical and scientific classes in college. I liked math and equations and rules, dreaded essay courses, and struggled to engage with the mandatory humanities courses. Something that I'm still learning, two decades later, is the extent to which this was because the humanities are harder work than the sciences and I wasn't yet up to the challenge of learning them properly. The problems are messier and more fluid. The context required is broader. It's harder to be clear and precise. And disciplines like sociology deal with our everyday lived experience, which means that we all think we're entitled to an opinion. Books like this, which can offer me a hand up and a grounding in the intellectual rigor while simultaneously being engaging and easy to read, are a treasure. They help me fill in the gaps in my education and help me recognize and appreciate the depth of thought in disciplines that don't come as naturally to me. This book was homework, but the good kind, the kind that exposes gaps in my understanding, introduces topics I hadn't considered, and makes the time fly until I come up for air, awed and thinking hard. Highly recommended. Rating: 9 out of 10
