Psychologists use the term automatic negative thoughts to describe the ideas that pop into our heads uninvited, like burglars, and leave behind a mess of uncomfortable emotions. In the 1960s, one of the founders of cognitive therapy, Aaron Beck, concluded that ANTs sabotage our best self, and lead to a vicious circle of misery: creating a general mindset that is variously unhappy or anxious or angry (take your pick) and which is (therefore) all the more likely to generate new ANTs. We get stuck in the same old neural pathways, having the same negative thoughts again and again.

There was a time when it was essentially illegal to be gay. There was a time when it was legal to own people and illegal for them to run away. Sometimes, society gets it wrong. And it s not just nameless bureaucrats; it s men like Thomas Jefferson. When that happens, strong privacy protections including collection controls that let people pick who gets their data, and when allow the persecuted and unpopular to survive.

1. There is no tcp_wrappers-devel in CentOS 5.
2. The perl libraries are in the main perl package and not in perl-devel.
3. lm_sensors-devel is not at version 3.

1. No tcp-wrapper support, we don't care but that should be just another package name issue for the conditional Requires, simililar to the perl isssue.
2. No mysql support. We do not care, one could change that and/or make it conditional or build against newer mysql releases where the -lib package is split.
3. No DTLS support on CentOS 5. We do not care and that is not easy to fix.
4. You've to install the net-snmp-sysvinit script to get back the usual setup you'd expect.
5. We ripped out the systemd support, I did not investigate yet if it's possible to keep that included and just not enable it.

1. If you build a src.rpm with mock you've to copy it out of the result directory before you rebuild it with mock to create the binary package. Mock deletes everything from the result directory when starting a new build. So I guess parallel builds for the same chroot will not work.
2. Depedencies on files instead of packages are a strange thing.
3. How on earth do you maintain a patchset of over a hundred patches without something like quilt? I guess you always have to apply them in a for loop on your source directory and then you create a copy of that to implement your modifications and create another patch. I'm pretty sure eight years ago Fedora was far away from using git so I would rule out patch branches in a VCS for the moment. Not sure what they invented inside RedHat to keep track of it.

It has to be as fast as possible, so interpreted languages are out. You don't want to micro manage memory, so C is out. You don't want to require programmers to have a degree, so C++ is out. You want fast startup and not depend on a big runtime, so Java is out. [...] (Bram Moolenaar)

Noticing a regression and reporting a bug There is a regression with Emacs 24.4 relative to 24.3, which I discovered after Emacs 24.4 became available in Debian's sid. The regression in particular is that Emacs 24.4 doesn't seem to respect my Xresources, while 24.3 does (and this is 100% reproducible: I kept the binary packages of version 24.3 of emacs24 and I can install and reinstall things). When I reported this to upstream, I received a reply that it worked fine with another person that was using XFCE with unstable.

Testing various Desktop environments As I am using the MATE desktop environment, I proceeded to test this assertion by installing XFCE. Emacs 24.4 read my Xresources. I went ahead and installed LXDE. It worked again. I tried once more with GNOME 3, but "regular" GNOME 3 just crashed. I tried with GNOME 3 Classic and Emacs 24.4 just worked again.

Going deep into the rabbit's hole Then, I got more curious and I tried to see why things worked the way that they did and given that there was a mirror of the Emacs repo on github, I cloned it and started to git bisect to find the first problematic commit (I have no idea if bzr even offers something like git's bisect and I wouldn't really know how to do it as quickly as I do with git). To cut short a long story, after many recompiles, many wasted hours, a lot of wasted electrical energy, I found a bad commit and reported it. I received no response after that.

The new repo enters in action Of course, all my hard work bisecting things was completely invalidated after the transition to the new repository went live. To make things relevant again, I used the awesome powers of git, restricting the changes of the newly cloned repository to the e-mail of the committer in question (Chong Yidong) and, from there, I proceeded to another painful process of git bisects. And, sure enough, the first bad commit was the same one that I found with the previous tree. Semi-blindly reverting this commit, and also semi-blindly resolving the conflicts make Emacs's from master work again on my system, but I highly suspect that (given the way that I did it), it would not really be appropriate for upstream. But given also that I failed to receive feedback after my original report, I am not too confident that this bug can be solved soon (even if it doesn't qualify for being fixed in Debian 8). After all this, I don't really know what else to do. I even filed a bug report (more like a request for help) to the Debian MATE maintainers. As a side note, I would have filed a bug to upstream MATE, but it is not really clear what the proper procedure to report bugs to them is---they seem to use github's issues system, but given that they have separate repositories for each component of the project, and that I don't know precisely what repository to report to (or even if it applies to MATE after all), I am more or less paralyzed.

A side note I must say that the conversion was well done by Eric Raymond, because the whole .git repository of the new repo is only about 200MB, with history going back to 1985, while the other repository had about 800GB.

Init system coupling GR: results (arrow from A to B means that voters preferred A to B by that margin)

• The turnout has been the highest since 2010 DPL elections and the 2nd highest among all GRs (!= DPL elections) ever. The highest among all GRs dates back to 2004 and was about dropping non-free. In absolute terms this vote scores even better: it is the GR with the highest number of voters ever. Clearly there was a lot of interest within the project about this vote. The results appear to be as representative of the views of project members as we have been able to get in the second half of Debian history.
• There is a total ordering of options (which is not always the case with our voting system). Starting with the winning option, each option in the results beats every subsequent option. The winning option ("General resolution is not required") beats the runner-up ("Support for other init systems is recommended, i.e., "you SHOULD NOT require a specific init") by a large margin: 100 votes, ~20.7% of the voters. The winning options wins over further options by increasingly large margins: 173 votes (~35.8%) against "Packages may require specific init systems if maintainers decide" (the MAY option); 176 (~36.4%) against "Packages may not require a specific init system" (the MUST NOT option); 263 (~54.5%) against "Further discussion" (the "let's keep on flaming" option). While judging from Debian mailing lists and news sites you might have gotten the impression that the project was evenly split on init system matters, at least w.r.t. the matter on the ballot that doesn't seem to be the case.
• The winning option is not as crazy as its label might imply (voting to declare that the vote was not required? WTH?). What the winning option actually says is more articulated than that; quoting from the ballot (highlight mine): Regarding the subject of this ballot, the Project affirms that the procedures for decision making and conflict resolution are working adequately and thus a General Resolution is not required. With this GR the Debian Project affirms that the procedures we have used to decide the default init system for Jessie and to arbitrate the ensuing conflicts are just fine. People might flame and troll debian-devel as much as they want (actually, I'm pretty sure we would all like them to stop, but that matter wasn't on the ballot so you'll have to take my word for it). People might write blog posts and make headlines corroborating the impression that Debian is still being torn apart by ongoing init system battles. But this vote says instead that the large majority of project members thinks our decision making and conflict-arbitration procedures, which most prominently include the Debian Technical Committee, have served use "adequately" well over the past troubled months. That of course doesn't mean that everyone in Debian is happy about every single recent decision, otherwise we wouldn't have had this GR in the first place. But it does mean that we consider our procedures good enough to (a) avoid getting in their way with a project-wide vote, and (b) keep on trusting them for the foreseeable future.
• [ It is not the main focus of this post, but if you care specifically about the implications of this GR on systemd adoption in Debian, I recommend reading this excellent GR commentary by Russ Allbery. ]

1. A bunch of containers that need Internet access
2. That are running in a VM
3. On your laptop
4. Behind your home router!

1. My border router (a DNS-323 running Debian) asks my ISP for a delegated prefix, using DHCPv6. The ISP delegates a /56¹. One /64 out of that is allocated to the network directly attached to the internal interface, and the rest goes into the pool , as /60 blocks (so I ve got 15 of them to delegate, if required).
2. My laptop gets an address on the LAN between itself and the DNS-323 via stateless auto-addressing ( SLAAC ). It also uses DHCPv6 to request one of the /60 blocks from the DNS-323. The laptop puts one /64 from that block as the address space for the virtual LAN (actually a Linux bridge) that connects the laptop to all my VMs, and puts the other 15 /64 blocks into a pool for delegation.
3. The VM that will be running the set of containers under test gets an address on the all VMs virtual LAN via SLAAC, and then requests a delegated /64 to use for the all containers virtual LAN (another bridge, this one running on the VM itself) that the containers will each connect to themselves.
