This week has been filled with all sorts of fun and challenging stuff.

For one, I used Wireshark to (successfully) diagnose a problem for the first time :D

The problem was an overly restrictive iptables rule on the system I was trying to connect to, but boy did it feel good to identify and solve that problem on my own.

I also managed to squeeze in time to write scripts to two work buddies so that they didn’t need to perform overly repetitive and very error-prone tasks by hand. The one script even needed a little bit of Expect-scripting, which I’ve been aching to hack some more.

I also found out about vim‘s :e # (to try it out, open a file in vim, then :e someOtherFile followed by :e #)

I found a very pedagogic explanation about how quicksort works, which made me start thinking and wondering about algorithms in general again, even to the point of investigating quicksort further.

I also found this post which makes a fair point: IFF you are going to rely on a web service (in other words, a SaaS you are probably better off getting hooked up with one charging money for it.

Not that I could ever conscionable recommend anyone using a SaaS as this is bound to lock you into dependence of that provider, but sure, I get that some (most?) would rather throw money at it than learning (learning is scary, and you don’t have the time right?) to set up your own service.

Furthermore, I can’t really decide whether the author is being disingenuous or illiterate in naming this stance an “anti-free-software movement”. It is unclear if s/he meant “anti-gratis-software movement” or if s/he is actually feeling threatened by free software. Had there been a comment field on that “blog” I probably would have spent the two minutes required to ask, but since there isn’t one, I won’t bother, and on pure principle, if I ever need a bookmarking-service, I’ll just make sure to stay clear of that one, just in case s/he actually was taking a jab against free software.

Yes, I am petty and vindictive at times, shit happens.

Whilst toying with the idea of modifying my homepage a bit, a site wide change, I realized that it might make a lot of sense to rewrite it so that it is, if not template-based, at least modularized. But I guess I’ll continue thinking about that before making any changes.

A funny thing I just thought of out of the blue the other day was that with some sites, like LinkedIn and probably Facebook and others, there are options for giving these services your email account username and password, so that they could log in, check your contact list, and hook you up with other people you know.

But I am pretty sure that most email providers license agreements state (no, I haven’t checked, but it would be foolish of these mail providers not to) that it would be a violation of said agreement for the user to disclose their account password to anyone else.

Then again, I don’t really understand people who would use those tools, but I guess there are even more people who wouldn’t understand why I chose not to…

A very interesting read about the Batman and the Joker. Those who know me can probably guess what character I voted for.

I’ve also been thinking about the prospect of storing binaries in some sort of version control, mostly because I have a friend who is into game development/modding, and doing so without version control. And that has bitten him in the ass more than once now.

And since I am nowadays a git convert I naturally started looking there, and found this, which lead me, among other places, here. Haven’t tried it yet, but it is definitively an interesting idea.

And now that I have begun working with Wireshark, tcpdump seems to be a good next step.

Finally, yet another reason why the patent industry needs to change.

Another week, another post :)

I had great fun at work this week. Loooong hours was looooooooooong, but at least I learnt a lot, and that I now have started playing with Wireshark.

Oh, and I got to code some small amounts of Python as well :D

Although most of the saturday was spent sleeping I did manage to discover some links I think I will just have to check out further:

  • Wemux, like tmux, but for multiple persons at once, I foresee this to be useful for either collaboration, such as remote pair-programming, or for lecture-style sessions
  • md2man, create man-pages using markdown and this conversion tool
  • Where Is Safe to Register a Domain Name? I’ll surely be thinking long and hard about this the next time I decide I need another domain

That’s about it for this week, hopefully next week will see normal amounts of work/hours and more free time to play with all the new ideas I got this week.

What I thought I’d do was I’d try some more tweaks, this one about categorization. Mostly because I think some of the neat things I’ve stumbled over in the past couple of weeks might not deserve their own heading. So I am revamping the headings:

Hacks

I thought this section would be about… not necessarily hacks, but if you would, the hacker mentality. Redefining a problem, is one such trait.

And building an eco-friendly house for around $5000 is defintively another.

Finally, Hacking Hacker News, which sounds like a rather fun project.

Tech

I’ve been meaning to learn wireshark, mostly because I could probably put it to pretty good use at work, and then I found pcap2msc which could probably be pretty useful for visualizing the collected data.

I also found a pretty useful site, Sleepyti.me which, given an average sleep cycle of 90 minutes, and user input when she wishes to wake up, calculates when the user should go to bed. Neat!

Commandline

I came across a very good explanation on how to use join.

I’ve also looked into how to increase trust in commits in git, namely by signing commits with your gpg key, and it turned out to be downright easy to accomplish.

Society

I guess that if we are completely ok with any potential ramifications of businesses keeping track of everything we buy, and speculating about what our purchases indicate, then it is completely ok to dispose of cash altogether. Personally it scares the willies out of me.

It’s funny how people seem to always confirm my concerns by abusing powers they shouldn’t have had in the first place…

I knew there was a I keep calling these guys the MAFIAA. Asshats…

While I understand this point and certainly agree to a certain degree, I maintain that if more people voted with their wallets, they’d soon run out of funds with which to buy new laws.
