Erich Schubert: Sch uble at LinuxTag 2007

Traditionally, the german ministry of the interior has been taking patronage for the LinuxTag. Which per-se is a good thing.However, the current minister of the interior has been publishing some "anti-terror proposals" that pretty much all opensource people see as a serious attack on their freedom, and that actually violate the constitution (or even the human rights, such as his statements towards torture).So this is a very odd situation: everybody would like to say "no" to him, but at the same time, welcome his ministry because of the good cooperation with opensource people the last years.IMHO, LinuxTag needs at least make a statement that while they welcome his efforts to establish the use of open source software in public administration, they can not agree with his political efforts with respect to the "war on terror", which pose a serious attack on the freedom of individuals.After all, there will be security experts at LinuxTag, and who if not they are capable of judging that e.g. the famous "federal trojan" won't be able to help much against organized crime (including terror organizations) because these can also organize computing safety (e.g. by not using Windows and not accepting executable data in email...). Or show up how much data abuse his proposals with respect to data gathering allow.

Erich Schubert: Munich Lindy Exchange

Munich Lindy Exchange 2007Registrations for the Munich Lindy Exchange (20. - 23. September 2007) are open.That will be a Lindy exchange to remember: this is the first Oktoberfest weekend, and of course the Lindy people will rock the Oktoberfest, too (apart from doing all kinds of other fun stuff, of course).(And yes, that means you should plan ahead - flights could become rather expensive during Oktoberfest. :-( )So if you are a Lindy Hop dancer, and want to meet some fun people, come to visit us. You won't be just a tourist, but you'll have "Munich natives" around you to show you all the cool places.Organized by Swing and the city (Christine von Scheidt).

Axel Beckert: Goodbye Woody, Welcome Etch

It finally happened. I installed Debian Etch on my last Woody box, a 400 MHz Pentium II with 576 MB RAM named gsa which is my home desktop since I bought it at LinuxTag 2003 in Karlsruhe. And no I didn’t do a dist-upgrade, neither direct no via Sarge. As already planned I removed some no more necessary operating systems from that box and installed Etch on the freed disk space. Woody is still installed on that box in parallel and was recognized perfectly by Etch’s installer. I took a few hours but also was big fun to go through Etch package list and to decide what to install. Overall the installation of 5 GB of software took about half a day. In general everything went fine, the only thing I’m yet missing is sound. Etch didn’t seem to recognize my soundcard at all although it’s a well-known brand and defacto standard for many other soundcards: a Creative Labs Soundblaster. Well, the 16-Bit ISA version, needing the full length of the slot. Worked fine under Woody. Well, I hope I’ll get it working again manually. What on the other hand is really nice with udev hell —eh— hal and all those new automatic bells and whistles: The desktop (well, at least GNOME Nautilus as well as XFCE, but probably also KDE) recognises when I insert a 3.5” floppy into the drive and shows me a nice floppy icon on the desktop. You think, that’s impossible? Floppy drives don’t inform the rest of the system when a floppy has been inserted without you polling the drive every few seconds? Well, USB floppy drives can. And they do. :-) I still need time to migrate all the old settings from Woody to Etch. I’ll probably stick with FVWM, but perhaps will use the GNOME enabled version. What’s already done is the migration from tcsh to zsh. On all new or dist-upgraded systems after Etch I’ve chosen zsh so with my last Woody installation retiring I’ve also fully migrated to zsh. So I’ve got now most of my active private boxes running Etch. Only the noone.org web and mail server “sym” (an amd64 box) as well as my 133 MHz ThinkPad “bijou” are still running Sarge, both with 2.6 kernels. So with switching to Etch on gsa, I also got no more Debian box running a 2.4 kernel. The only 2.4 kernel I run is on my FreeWRT WLAN router named pluriel, which runs 2.4.33.3. But I expect that 2.6.18 will be as stable and long lasting as the famous and rock-solid 2.4.18 from Woody. 18 seems to be Debian’s favourite kernel minor version recently. ;-)

David Welton: Google Apps + Domain Registration

I'm impressed. Via Google Apps, I was able to register a domain (squeezedbooks.com - nothing there yet, though) for $10. But it's not just a domain, it comes with email, google calendar, and a bunch of the other google apps thrown in for free. That's a lot of stuff for ten bucks - especially for the large portions of the world where the currencies are appreciating against the dollar. The service does have some drawbacks though.

Cord Beermann: private Spamstats April 2007



you see my Spamstats for the time i run an own server for my domain.

The input consists mainly from cord@Wunder-Nett.org that is in existence since mid-1996, and a (tuned) catch all on cord.de.



In 05/2004 i had a big downtime due to broken Harddisk and/or cheap IDE-Cables (which was finally solved in 2006).

In 11/2004 i became Debian-Listmaster, and forwarded the listmaster-mails to my system.

In 08/2005 i stopped forwarding listmaster-Mail and the admin-mail from LUG-OWL and let them drop into a local Mailbox on the specific servers.

In 06/2006 The power supply of my server died, and HaJo had a fitting spare device, so i took it to the local hardware gods (C&M sorry, only Flash) and they put implanted it, they also replaced all Fans (6 of which 4 were stuck) and replaced the IDE-Cables. Now i even could switch on DMA without risking a crash. (Man, 3years of crippled server). As you see, the system is now able to accept even more spam.

In 12/2006 i added greylisting on my server. My 2nd MX currently doesn't do greylisting.


Management-summary: With massive filtering i can keep mail somewhat useable for me.

Chris Lamb: Final report complete!

Just submitted my third-year project. Was probably the longest document I will ever write:
$ wc -w  find ~/local/bzr/3yp/docs/report -name "*.tex"    tail -n1
19234 total
$
(If new readers are picking up the story late, in the final year of the Warwick Computer Science course, students are required to undertake a reasonably sized project. I chose to write a Java compiler in Python.) Actually writing the report was a bit more painful than I thought, dispite having collected and organised most of the data, references and interesting topics well in advance. I’ve nearly overcome some sort of writers-block-cum-nervousness issue though, which is good. I got a few interesting results: My backend system had a peephole optimiser to run on all code regardless of the input language and it seems like Sun’s javac seems to miss out on many really trivial optimisations, probably because the JIT takes care of any performance blackspots. Regardless, I plan to have a go at adding this into OpenJDK after my exams just as an excuse to hack on the Real Java. (I also did some register allocation, also beating javac, althought I didn’t really investigate way) I’ll have to wait for while due to University regulations anyway, but I’m not sure if the project code is really fit for public consumption yet, but I plan to rip out the silly Lisp implementation (and most of the Java one) leaving a rather fast and “enterprise-ready” Brainf*** compiler. :)

Cameron Dale: May-02-2007

Well it's been a busy week. Work is truly underway, as I have just about finished the first release of debtorrent. The first step in the process, adding variable-sized pieces the size of each file, has been completed and seems to work properly. I've tested it using a single seed, and with 3 downloaders. All were able to contact each other, and all downloaded the entire archive successfully. The archive I tested it on was stable/contrib/i386, as it is only 112MB. There's just a few more modifications to make to polish the code, and then the 0.1.0 version of debtorrent should be released in the next week. It would be out already, but I've been plagued with a cold for the last week. I had a lengthy discussion with Anthony about the eventual need for some modifications to the apt-ftparchive program to support some of the proposed advanced debtorrent functionality. More investigation is needed on the implications of these changes, which will probably require larger Packages/Release files to be generated, and some extra computation time. To collect information about these changes and their implications, I've created a new wiki page.

Mike Hommey: Bug triaging

A week ago, I started the long overdue task of triaging bugs reported on iceape/mozilla. When I started, the count was 364, duplicated excluded. I’m still not halfway through the bug list, but already the bug count is down to 263, as of today. That is about a hundred bugs closed or merged. I can’t believe there were still bugs so old but yet not merged to even older occurrences of the same bugs. Since it is easier to appreciate the effort with nice colors, I started graphing the bug counts for iceape. Sune Vuorela started some similar things for kde a while ago, so, thinking this could be useful for a whole lot more people than KDE and Mozilla maintainers, I also started graphing the bug counts for all packages. There is not enough backlog to have more than the last week, though. I’m a bit concerned about the fact that the RRD updates take a lot of time and may induce some load on gluck… Please DSA hit me if you want it to be moved elsewhere. Anyways, back to iceape bugs, the oldest bug I closed was #80787, which was actually fixed as soon as I first uploaded xulrunner a year ago. On the other hand, the oldest I didn’t close is #78654. There are some other winners that I’m amazed they’ve not been treated upstream in the last 6 years. Now, while I tried to correctly and conveniently tag these oldest bugs, I didn’t take the required amount of time to track them in upstream bugzilla. So if you, dear reader, have a little bit of time, I would really appreciate if you could go through the list of bugs* that are tagged upstream, but not yet forwarded and either find them in upstream bugzilla, or file them if they don’t exist there. * strangely enough, the raw=yes argument to the BTS doesn’t seem to work properly. You can get a raw list (with no ordering by status or severity) through the LDAP gateway with the following command line:
ldapsearch -p 10101 -h bts2ldap.debian.net -x -b dc=current,dc=bugs,dc=debian,dc=org '(&(debbugsSourcePackage=iceape) (debbugsTag=upstream) (!(debbugsState=forwarded)) (!(debbugsState=done)))'
Note the LDAP query is probably not optimal. You can add debbugsID at the end of the command line if you’re only interested in the bug numbers.

Alastair McKinstry: Gliese 581 c : An Ocean Planet ?

Now that the weekend is here, I've been catching up on the news of this weeks big astronomy announcement: the discovery of a possible "Super-Earth" exo-planet, Gliese 581 c. This is the first exoplanet likely to be within the so-called "Habitable zone" around its star, where life as we know it could be possible. Unfortunately the Irish Times "World Apart" weekend supplement article has been quite disappointing. Like Greg Laughlin at UCO Lick I get depressed when people give misleading information . It includes a very misleading "Artists impression" picture, simultaneously showing details we don't know and being incorrect about the few things we do know. Its easy to get annoyed at the concentration of facts that are guesswork or probably wrong in this article. Gl 581c is not 5 Earth masses: thats its minimum mass: due to radial velocity measurements, we can only measure M sin(i), where i is the inclination, currently unknown. It could easily be far more, and hence all predictions of what the planet is like become moot. Similarly, the radius is not necessarily 1.5 times Earths: thats a prediction, based on the mass, and current theories. Unfortunately, there is no mention that current theories of planetary size are coming under scrutiny as they fail to match other recent exoplanet discoveries. This makes other speculation about the planet such as the gravity on the surface quite misleading. The BBC News summary is much better: it refers to the radius as "the radius should be", rather than "is". But it too includes the incorrect picture. While its article is couched in more conservative language, it doesn't explain what facts it quotes are speculation and why they may be wrong. None of the media reports I have yet seen mention current missions, such as COROT, which is the most likely to find Earth-sized planets in the near future (launched late last year, it is due to finish its first observing run in April. Results awaited with anticipation). They also ignore Darwin and the The Terrestrial Planet Finder, the most likely missions to discover life on other planets, but currently sitting in funding limbo. Concentration on purely the known facts would of course make the news reports short and boring. Instead they should emphasise more of the work of the scientists involved: we teach science as a set of cut-and-dried facts that often bore school students and drive them away. Instead, when faced as the cutting edge of an important discovery like this, we could show how an amateur could be partially credited with getting this result; with the fact that, since the planet has a short "year" astronomers are already lining up to investigate transit measurements of it on May 7 and that with a magnitude of 10.6 (only 20 light years from Earth, after all) its within range of amateur astronomers to observe and determine its true size and details. How about getting people excited to get involved themselves?

Adam Rosi-Kessel: Proof of Spring 2007

For anyone who doubts the arrival of Spring 2007: Flower Spring 2007 Update: all of the below was fixed by disabling Privoxy! Who would have guessed?
Meanwhile, I can’t for the life of me get the gallery2/wordpress integration plugin (wpg2) to work. I decided it was time to get organized and stop storing/uploading photos in a totally ad hoc fashion. When I try to validate the wpg2 installation, however, I get this error: Warning: Cannot modify header information - headers already sent by (output started at /home/adam/public_html/weblog/wp-admin/admin-header.php:16) in /home/adam/public_html/weblog/wp-includes/functions.php on line 1221 When I then click to confirm that I want to validate, I get an empty page back. No errors in apache logs. This problem appears to have come up several times, and the most I can gather is the Gallery people point the finger at the Gallery Plugin people; the Gallery Plugin people point their finger at the Gallery people; and sometimes everyone points their finger at the Wordpress people. E.g. Not the best way to spend a beautiful spring day.

Benjamin Mako Hill: Reflections on the War on Share

I'm giving a talk today as part of Media in Transition 5 (MiT5) conference organized by the MIT Comparative Media Studies program. The topic this year year is right up my alley: "creativity, ownership, and collaboration in the digital age. Everyone else is talking about free culture issues so I'm branching out a bit and delivering a paper I wrote with Harvard Law School and Harvard Free Culture's Elizabeth Stark on "the politics of piracy" with a focus on political action around P2P filesharing. We'll have a paper in the proceedings which I'll post with our talk notes and slides. You can find information on our talk on how to attend on the conference website.

John Goerzen: Online Internet Bank Review

Back in mid-2000, I set up my first Internet bank account. I have been using the same bank ever since. The whole notion of Internet banks has changed a lot since then, since virtually every bank offers varying degrees of online access these days. Lately I checked on banks to see if I was still using the best one. Here are my reviews of the two banks.

Internet Banks

Let's first talk about what makes a bank an "Internet bank" or "online bank". So many banks let you manage your account online now, that the distinction is blurry. But generally, I would say that unique features of Internet banks are:



There are a few to highlight.

Real-time transaction posting is a great thing to have. If you go to the website and transfer money from your savings to your checking account, you can go to the ATM *now* and withdraw it, and when you get back to your desk, the ATM transaction shows up. There are none of these confusing "business day" rules with cutoff times that traditional banks seem to love. And none of this annoying "process all withdrawals first" business that large traditional banks (hello, Bank of America) love to do in order to screw with customers.

High interest rates. Don't even bother with an online bank if the savings interest rate is less than 3% (or checking less than 1%, in my opinion). It is almost impossible to find a traditional bank with these rates.

Note: if you're reading this after April, 2007, these guidelines may no longer apply due to interest rate changes.

Electronic transfers from other banks. Another great feature. A number of banks let you set up, and then initiate, electronic transfers to and from your accounts at other banks. This is usually free if you are using the feature to transfer money into your account, and with a flat per-transaction fee (usually about the same as a foreign ATM fee) for transferring money out.

Ability to do all business without visiting a branch. Not only should this be possible, but routine business (such as making deposits) should be easy to do without visiting a branch. You should be able to order new checks online.

Now let's look at the individual banks.

First Internet Bank of Indiana

FirstIB (they provide nationwide service, despite the name) is the bank I signed up with in 2000. I had found a bank in Dallas that I really liked, but when I moved to Indianapolis, I tried two and liked neither. They all seemed to have really poor interest rates, offer few useful services, and fees for so many conditions that it was hard to avoid them. (More on that in the traditional banks section below)

I looked at the online banking scene at the time, and wound up opening a checking and savings account with FirstIB. FirstIB started as an online-only bank, but recently acquired a bricks-and-mortar bank as well.

I found FirstIB's customer service at the time to be top-notch; I would dial their toll-free number, select *one* option from a menu, and a rep would answer *immediately*. (Take that, Bank of America, with your 45-minute hold times...) Since FirstIB was based in Indianapolis, I actually visited their offices a couple of times. They had a locked lobby. You picked up a phone, pressed 0, and went into the same queue that callers to the 800 number did, then just asked them to come to the lobby and transact your business. (They would not give out cash there, but could take new account paperwork and deposits and the like)

Their interest rates have consistently outperformed traditional banks, and they offer all the online banking amenities listed above. They did not offer online statements at first, but these days online statements are the norm (there is a fee if you want paper statements). Check ordering is accomplished using a linking with the Deluxe check printers. The web interface uses Digital Insight, and the ACH transfer interface uses CashEdge.

FirstIB will actually reimburse you, at the end of the month, for ATM fees that other banks charge you, up to $6/mo. They also provide an unlimited supply of free postage-paid deposit envelopes, and have a PDF of deposit slips that you can print out should you run out.

FirstIB's customer service has slipped in recent times. I know of some people that have been impacted by some errors that FirstIB has made (simply not processing paperwork that they should have processed). Wait times have gone up for the phone line, and a lot of the great "small bank" feel (where they actually knew their customers, and you might actually know the reps) is gone.

Presidential Bank, FSB

Presidential Bank is the bank I'm looking at now. I was initially drawn to them by their extraordinarly high interest rates (5.25% for savings!), but some other things have convinced me to use them.

Initially, I was suspicious. Presidential is a bricks-and-mortar operation that has been around for awhile, and was one of the very first Internet banks. Their website says that they started offering Internet accounts in 1995, and very much looks like it hasn't been updated since. (Thankfully, the account management interface is more modern). I almost thought the site was a fraud up front, a "too good to be true" deal with the high interest rates and bad-looking website. But after doing some research, realized that it is quite real.

Before setting up accounts with them, I had a few questions (such as whether or not transactions post in real time). Presidential has a simple email address for people that want to send in questions (unlike FirstIB's obvious queue system). I sent an email, and got a response an hour or two later, from a real person with a first and last name, and a personal e-mail address I could use to follow up. Nice. I also had occasion to talk to people on the phone. They were polite, speedy, and helpful.

So I set up my accounts with them. I activated the online access, bill payment, and money transfer features. All worked as expected. I did have a couple more occasions to call them after the account was set up (a more crucial test than the pre-account calls), and they remained helpful. Strangely, this bank, which seems to be a much larger operation than FirstIB, had a more small bank feel. Several times, as I started talking to a rep, he or she would say something like "Oh, I remember processing the setup paperwork on this account last week" or "I think I talked to you about this before?"

Customer service is one of those things you rarely need after the first month or so of an account. But with your bank, it is vital that the reps know what they are doing and are willing to help you when you call -- which Presidential is doing better than FirstIB these days.

Presidential does not rebate ATM fees like FirstIB does. They do provide a few deposit envelopes with your initial account setup packet, but they are not postage paid or unlimited. However, because Presidential's interest rates are so much better than FirstIB's, it doesn't take much in your account to more than balance out that difference. Plus, with so many retail stores offering "cash back" when you use an ATM or debit card, it isn't too bad to get cash for free with Presidential. (And, most employers offer direct deposit, so we rarely use deposit-by-mail) One other trick is to find some local bank and open a no-minimum free checking account with them. You can deposit checks there and withdraw cash from their ATM, and use Presidential's free incoming ACH to electronically transfer the funds to Presidential when you get too much in the local account. (Chances are that these local accounts will not pay any interest)

Presidential offers a few features FirstIB does not. First, they scan all your deposits (not just your canceled checks) and offer to let you view them online. Secondly, they automatically send you an email when they've received a bank-by-mail deposit (you can opt out of that, of course). Third, they let you view *all* of your old statements online (FirstIB only lets you view the last 6 months worth, though both have the complete history available in the web interface).

Like FirstIB, Presidential uses DigitalInsight for the web interface and CashEdge for the ACH feature.

Online options at traditional banks

As I mentioned, Presidential is a traditional bank that has offered Internet accounts for some time now. Some other traditional banks do that as well, but look carefully at them, especially if they're a big nationwide bank.

I looked at options from Bank of America, Citibank, HSBC USA, ETrade Bank, and some other large national banks. In general, these were just regular bank accounts with a web interface (HSBC and ETrade being somewhat of exceptions). Read the fine print and you'll find poor interest rates and traditional banking hassles (lack of immediacy in transactions, predatory posting practices, fees for just about everything).

Plus I can tell from personal experience that Bank of America customer service is downright awful. One example: they used to pressure me to open a credit card with them every time I visited a branch. I declined every time, and had to be forceful about it sometimes. Then one day, not long after a visit with a particularly annoying employee, I got a Bank of America credit card -- which I had specifically refused -- in the mail. Hmmmmmm.

They also, unlike any other bank I've ever used, charged a fee to receive wire transfers. Which they had not disclosed. Then, of course, they apply withdrawals before deposits, and caused an overdraft from the undisclosed fee, even though the wire transfer was a *deposit* that would have very easily covered it. That was the last straw for me. After nearly an hour on the phone with them, I got them to agree to reverse both the fee and the overdraft charge. THEN I said I wanted to close my account.

When traditional banks are better

There are a few situations where Internet banks don't work out so well:

Living paycheck to paycheck. If you are constantly running out of money, and it is vital that any deposits get posted *NOW*, you probably don't want an Internet bank (and wouldn't benefit from their higher interest anyway). When you mail in a check, it can take some time before you have access to the money; the postal service has to deliver it, and then most of your checks will be subject to the "non-local" availability policy and held for about a week (though interest will start to accrue immediately).

Not being able to meet minimum balances. Internet banks do tend to offer a variety of accounts, but if you aren't able to regularly maintain $500 to $1000 in your checking account or $2000 to $5000 in your savings, you will likely fall into a category with lower interest and fewer free benefits. These accounts may not have many benefits over traditional banks, and may in fact be worse in some ways. The interest rate gap won't make that much of a difference either. There are several online banks that offer savings accounts only, with high interest rates and low minimums, that you may want to investigate -- though you will have availability into your checking account measured in days, not seconds. Presidential's savings has no minimum, but requires $5000 to open. (They do have lower-interest savings accounts without that requirement) Watch out for FirstIB's accounts; you can open an account with less than the monthly minimum balance, and will run into fees unless you deposit enough to meet the minimums.

Gunnar Wolf: tbm's Release Management talk

Thanks to Romain Francoise, I found and watched Martin Michlmayr's Release Management in Large Free Software Projects talk on Google Video's Open Source Speaker series. Martin: Thanks a lot, great talk. I've been following your presentations lately, as I've given some talks on this topic - Quality Assurance on Free Software Projects (Spanish only) - However hard I try to remain faithful to the subject, I end up giving a talk on what Free Software is and how its processes are naturally more prone to yielding better quality than propietary projects.
Anyhow, with this post I want to do basically three things:

Russell Coker: first look at CentOS 5 Xen

I have just installed a machine running CentOS 5 as a Xen server. I installed a full GUI environment on the dom0 so that GUI tools can be used for managing the virtual servers.

The first problem I had was selecting the "Installation source", it's described in the error message as an "Invalid PV media address" when you get it wrong which caused me a little confusion when installing it at 10PM. Then I had a few problems getting the syntax of a nfs://1.2.3.4:/directory URL correct. But these were trivial annoyances. It was a little annoying that my attempts to use a "file://" URL were rejected, I had hoped that it would just run exportfs to make the NFS export from the local machine (much faster than using an NFS server over the network which is what the current setup will lead people to do).

The first true deficiency I found with the tools is that it provides no way of creating filesystems on block devices. The process of allocating a block device or file from the Xen configuration tool is merely assigning a virtual block device to the Xen image - and only one such virtual block device is permitted. Then the CentOS 5 installation instance that runs under Xen will have to partition the disk (it doesn't support installing directly to an unpartitioned disk) which will make things painful when it comes time to resize the filesystems.

When running Debian Xen servers I do everything manually. A typical Debian Xen instance that I run will have a virtual block device /dev/hda for the root FS, /dev/hdb for swap, and /dev/hdc for /home. Then if I want to resize them I merely stop the Xen instance, run "e2fsck -f" on the filesystem followed by "resize2fs" and the LVM command "lvresize" (in the appropriate order depending on whether I am extending or reducing the filesystem).

Xen also supports creating a virtual partitioned disk. This means I could have /dev/lvm/xenroot, and /dev/lvm/xenswap, and /dev/lvm/xenhome appear in the domU as /dev/hda1, /dev/hda2, and /dev/hda3. This means that I could have a single virtual disk that allows the partitions to be independently resized when the domU in question is not running. I have not tried using this feature as it doesn't suit my usage patterns. But it's interesting and unfortunate that the GUI tools which are part of CentOS don't support it.

When I finally got to run the install process it had a virtual graphics environment (which is good) but unfortunately it suffered badly from the two-mouse-cursor problem with different accellerations used for both cursors so the difference in position of the two cursors varied in different parts of the screen. This was rather surprising as the dom0 had a default GNOME install.

Mark Brown: Polling for changes

Gustavo’s advice to poll the Ubuntu patch archive for useful changes doesn’t have to be restricted to Ubuntu - for a long time I’ve regularly trawled at least the Red Hat/Fedora and SuSE packages for useful changes. The utility of doing this does vary with the package (typically inversely with the volume of upstream code changes that distributions tend to carry about) but for the time it takes to at least check to see if there’s anything interesting I find that it’s worthwhile. Doing this is no substitute for getting patches submitted properly with good documentation and extraneous changes stripped out. Personally I have always been fortunate in the people working on my packages in Ubuntu - I’ve almost always found that the changes that are applicable to Debian have been sent to me already by the person making them. I’d go so far as to say that most of the substantial patches I’m given come from Ubuntu developers. In the one case this hadn’t happened the person making the change was surprised and apologized that they’d forgotten.

Those queries are available on the command line too and behave exacly as if entered in the program: The syntax is: rng [QUERY], where query is one of the above (and rng a convenient shortcut to reportbug-ng). An example: if you start rng from:venthur@debian.org, you’ll get the full list of all bugreports I’ve ever reported. Now you can filter the list to find all bugreports I’ve filed against, say: qgo… voila. It doesn’t get any easier than that, does it? Those new queries and a few changes under the hood required quite a lot of refactoring in the code and I’m somewhat scared that I’ve introduced some new bugs. So I guess I should stop releasing so often (or for at least 10 days so rng can finally enter testing) and use the time to start writing some unit tests.

David Welton: Linux Incompatibility List

As I take stock of things in my life after our move to Innsbruck, I'm thinking about what to do with the Linux Incompatibility List. I think the site could grow in some ways to get people more involved with the life cycle of identifying what doesn't work with Linux and then fixing it. There are also some tech changes that I could do. However, I'm also thinking that running the site is not part of what I want to focus on long term. It seems to have been pretty successful so far, having garnered a mention in slashdot and other news sites, and has seen a steady stream of modifications and additions. Since the adsense from it nearly pays for the server that hosts it, I've also been considering the idea of selling it somewhere like sitepoint, but I'm a bit reticent to do that, because the money part of it has to be secondary to providing a useful service to the Linux community. I wouldn't mind making some money off it, of course, although I don't think it would be much but I would have to be certain that it "went to a good home" as they say. I wouldn't mind having fewer advertisements even as things stand now, so I certainly wouldn't want to see it "monetized" by being crammed full of ads. Thoughts? Suggestions?

Jan Wagner: Is DNSSEC ready for wild life?

Today the RIPE DNS for LIRs Training Course did take place. (some not up to date course material can be found here)
Managing some thousands of zones inclusive nameserver infrastructure behind since several years, I thought it would be neat to provide a secure dns chain to our costumers.
After going deeper into the material within the course, I recognized the following impacts: Since the last issue isn’t solved (yet), it doesn’t make any sence for me to invest resources into setting up DNSSec infrastructur, cause the end user would not recognize if the communication with the resolving nameserver or the resolving nameserver itself is taken over. Any complaints and/or hint? Did I missed something? , , ,

Christian Perrier: Dropping the size of my server's mail queue

In my server's postfix main.cf file: bounce_queue_lifetime = 8h This, instead of the "5d" default, reduced the size of the mail queue on my server from 1200 mails to 130. In these days where spammers just spam randomized addresses on servers, that sounds to be a good idea. Dear Lazyweb, other suggestions? Or is this indedd a not so good idea?
