PuTTYJL

After putting up with the lack of support for Windows 7’s jump lists in PuTTY for a while, I finally got tired enough of it to do something.  Nothing as cool as patching PuTTY to do them itself, but I wrote a wrapper which indexes the saved sessions, allowing the user to select which ones should be included in the list.

From the project page:

PuTTYJL is a wrapper and patch for PuTTY written in C# for .NET 3.5 and Windows 7, adding support for the new Jump Lists, allowing you to create jump list entries for saved sessions in the registry and optionally just launch the wrapper to start a default session in PuTTY.

Hacking life

Today (er, yesterday) was a big day for science.  In the May 20th issue of Science, there was an interesting paper detailing how researchers at the J. Craig Venter Institute (yup, name means nothing to me there) successfully created a life-form containing entirely artificial DNA [abstract,PDF].  This is really exciting stuff.

As the authors of the paper note, sequencing genomes is nothing new, but there’s a gigantic leap between just knowing how something is made and being able to make it yourself.  Although this modified strain of yeast has mostly stock genes from other yeast and just over a million base pairs, Wired Science notes that our ability to manufacture chunks of DNA has grown by around 100x in the last five years.  Following such a linear pattern, we would be able to build a human genome from scratch (~3 billion base pairs) within ten years.  From here, where can we go?  Anywhere.

Consider what living things do in nature.  Now take some of that variety and modify it a little to do something more useful.  Say, design an enzyme allowing yeast to break down oil from spills and removing any other metabolic pathways.  You suddenly have a bacterium which eats oil spills, then the colony dies when the oil goes away.

Sure, something like that is a ways off; we don’t have anywhere the necessary knowledge of the biochemistry involved in such a thing (or do we..?  I could be entirely wrong).  Proteins are amazingly complex molecules, and their assembly/folding is rather poorly understood at best.  However, give it a while, and we could begin to do radical things within the framework of living things.  Say, custom-designed viruses to patch our genomes.  Literally, life hacking.

This is simply incredible stuff, and it’s the first step toward the singularity, IMHO.  More thoughts on that in the coming days.

Ubunchu?

Go read.  You can come back in a bit and be mildly confused.

CLI-tan
Look, it's CLI-tan.

..or don’t (if you did, good).

Ubunchu is.. interesting.  I’ve lately taken to ignoring most things that so much as mention UbunchuUbuntu (as my StumbleUpon history will attest to), but it’s good to know that there’s still plenty of sense, if you know where to look.  Not everyone is spewing nonsense from their nostrils, evidently.

The truth is over there

There’s a pretty impressive amount of truth lurking in Ubunchu under the silliness and not-quite-OS-tan levels of moe.  Basically every opinion voiced in the manga is accurate, IMHO.  In my mind, there’s a place for each OS- each has is strengths, and certain weaknesses- what you get from any system is a combination of what it can offer well and what you put in.

Ubuntu, for example, is a very newbie-friendly Linux distro, and it’s very good at being free and (generally) easy to use.  Try to control it too much, and it might break on you- that’s just how the game works.

Arch, my Linux distro of choice, is quite different- it’s one that expects you, the user, to go poking around and configure things yourself.  Arch is great at being configured to exactly fit your needs, provided you’re willing to take the time to learn things for yourself (do eeeet, I say).

Windows is good at being itself- not free, but generally worth the price for those who know what they’re doing.  I’ll freely admit that Windows tends to be overkill and even something of a liability (what with malware and all) for uninformed users, but I feel that power users can get a lot out of Windows with excellent dev tools like Visual Studio, a huge multitude of games, and the multiple ways to do just about anything.  Say what you want about Microsoft, but their developer support is superb.

OSX?  Well, it’s good at being simple to use and not free.  I won’t say much on that since I generally make a point of ignoring Apple products, but I hear such systems are well-liked in the creative community.  My main complaint is that it generally only gives you one way to do whatever it is you might want to do, which is rather painful for someone like me, who likes to poke around in things.

Bottom line

Operating systems bring a variety of benefits to the table, and it’s up to you, the user, to decide which one(s) fit your computer usage style best.  Now if you’ll excuse me, I’m off to SSH into my server to check on my CLI IRC client. ( ^‐^)_

Oh, and I want a sysadmin’s club.

CPU Comparison Shopping

I’ve been slowly working towards putting together a new PC build to replace my current one, a Core 2 Duo- based system I built about three years ago, which is starting to show its age.  In the interest of comparison shopping, I put together a spreadsheet and some charts looking at the newer Intel (i5/i7) and AMD (Phenom X4/X6) processors.  Turns out that Intel’s Core i5-750 seems to be the best deal in processors for what I’m looking for in a system at the moment.

Raw Data

Clock speeds are in MHz, TDP in Watts, and cost is price in USD at newegg as of 5/3/2010.  Processors with SMT (hyperthreading) are noted in the Cores column.
