In a nutshell

xbtt sucks. I'll write more when the project is finished. Stay tuned.

Well, maybe it doesn't suck so much, but it:

  • is not a silver bullet
  • have some major design flaws

They are totally useless. Unless you have to perform a certain task. If you don't list every little thing you have to do to achive your goal, you may miss a teeny-tiny part, like updating fstab after moving directories. And end up screwing with the server all night long instead of 10 minute job.

BTW, if you use pygrub with Xen, extra won't work and you won't be able to boot domU in single mode, for example. You'll have to specify kernel and ramdisk and comment out bootloader instead.

Back to RentACoder

I've stopped freelancing for a while again, and now I'm back to it one more time.

I missed it. I left RAC over 2 years ago becase of several reasons. Most important are:

No challenge

When I stated there, it was all new and exciting for me. Finding clients, persuading them to hire me, working on real things I only tried on localhost before... But them I gained enough experience and improved my skills. Most projects looked boring for me. Others were too cheap (I know, a gig's a gig, but working for $20 overnight isn't so pleasing anymore).


I was working for two guys I met on RentACoder, Leif and Matt. They paid me enough so I didn't have to search for more projects. Also I found a full-time job which also paid off pretty well. I had enough money and enough work and also some free time: why would I need too work more.


Well, my skills are good. My rates are acceptable. But by the end of 2007 RAC was invaded by thousands of cheap Indian coders. I just couldn't compete with their rates. No offence to good coders from India: they had even harder time fighting both their cheap inexperienced colleagues and a stereotype about cheap coders...

But recently I moved from my parents house and could really use a couple extra bucks. And also I suddenly had much more free time (I still have no explaination for that!), so I though: Why not? And RAC was much better this time: more interesting projects, less scriptkiddies (I made 8 bids in first two days and won one) and decent prices. I'm glad and excited.

It's good to be back.

It's unique. What's it's uniqueness, you ask me? I'll tell you what is it. rsyslog's man page is more clear and easy to understand and to start with than documentation at it's website.

We've grown enough to need high availability solution, so the first thing I've tried is Heartbeat. It turned out enough for now (although, I'll have to update a few init scripts), and I'll write a mini-howto on running Heartbeat inside OpenVZ container as soon as I have enough time for that.

For now, just one hint. If your node doesn't come up when it should, and /var/log/ha-log contains the following:

Setup problem: Couldn't find utility /bin/gawk

then it's most probably not really about gawk (it's very hard to find Linux system without gawk). It may also mean that you don't have which installed, while Heartbeat's scripts use it to find a real path to gawk. It's not that common, too, actually, but, for example, some OpenVZ templates do not include which package.

So, yum install which (or vzyum $VEID install which) brings you happiness.

Ubuntu is so Ubuntu

Note to self: stop using alphas!

This shit costed me a lot of neurons and hell of a time. I though I went crazy ot supid at some point.

I even googled for 'netmask calculator' after I calculated it in head and then on a piece of paper.

Both ip addr and ifconfig output wrong broadcast address.

% uname -a

One Month In Office

As I have already mentioned, I got a “normal” nearly full-time job recently. I work in a web hosting company (Russian) now. And I promised to write an artcile about how is it after a month of been employed. So, here st it.

I'm few days late, though.

It is hard to distinguish pros and cons right now as I'm all into this new job. It's new, it's interesting, it's (somewhat) challenging, it fits me perfectly. Hm.. Okay, let's state that was a pro.

On the other hand, it's in office. It means I have to be clothed (and I mean clothed, so robe and slippers ain't an option) to work, I have to move myself from home to office in the morning... That turned out pretty hard, I've never been and early-riser, so I didn't have enought sleep first two weeks and still I feel that if I could sleep more, I'd feel better.

I can't make coffee or tea in the office as I used to make them. Actually, there's no way to make fine coffee there (can't stand instant coffee), the tea I make there is acceptable, though.

It's harder to take a break in office, and you have to go through from morning to lunch and from lunch to evening. It's okay now, though, as I even forget about lunch sometimes (that will surely pass later). Opposed to this, it's easier to concentrate: “home freedom” gives you too many chanes that you'll reading blogs or playing Chromium rather than working. I was sick a couple days ago and had to stay home and tried to work from here as I used to do all those years. And what? Routine tasks took two times more than they usually take when I'm in the office. And I missed our issue traking system and lots of things I just got used to already. And most of all I missed the ability to turn my head and ask co-worker a question instead of emailing it.

BUT. I have weekends now. I can do anything (or nothing, which I prefer) after 6 AM. And I know what will I be doing next day. After three years of freelance it feels marvelous! I guess I'm getting fat-old-stability-loving-guy.

Also, I can learn now. First, new work means new challenges, and I have to improve some of my skills, which were pretty weak before. I never had time and need to get beyond just general understanding of perl, bash, sed and awk. I barely understood how MySQL replication actually works. I knew nothing about PAM, NSS and postfix.

And I can actually learn: read books and manuals on things I do not use in my work. Just because I've got free time now. Finally I'm reading Dive Into Python and I like this language and will try to build my next own project with Python.

I don't have to pay attention to my time management anymore. No need to explain anyone, why do I have to work when they want to see me. Less interference between work and my (yet inexistent, though) private life.

And the last thing for now, I guess, is pro office work again. I can get enough resources when I need. I cat ask for a test server, so I don't have to manage virtual machines and virtual network. I can ask for software, though I never needed it yet and I doubt that I'll be need of something non-free in future.

Uhm. The very last: I know now what is TGIF really about, and I don't like it very much actually.

You see, there are much more pros for me now. Actually, this job is a good balance between freelance and what is usually ment by office work.
