Java

It seems that Java was open today. I can't help thinking that Sun was nudged by gcj. I run gcj web plugin in Firefox to access Bladecenter, and gcj proper to build and run small Java toys (like USBMon). I also tinkered with running Azureus and RSSOwl, and although they aren't mainstay applications for me, they are not little toys, and they work with gcj and Classpath. So, Sun opened Java when it became patently obvious that Classpath is on the course to obsolete Sun's implementation.

Regardless of the reasons, I think that open Java is great news. I loved hacking in Java. The language was great. Libraries were... hard to evaluate for a drive-by programmer like myself, but I saw them getting better quite a bit (especially when you count non-Sun things like SWT, RxTx, etc.).

I never was big on WORA (actually, considered it a marketing fraud personally), so I gave a thought to liberating Java from the grip of it. When at Sun, I looked into having Forth-based firmware replaced with Java-based one -- naturally with a non-SE runtime. It would provide immense benefits (such as interrupt processing). Some were unobvious. Everyone at Sun, except perhaps Ping Lee, considered hacking FCode a career end. Once a manager knows that you are familiar with FCode, you get tasked with it, because everyone else is so keen to avoid it, and that is forever. Your only choice is to go management, or to quit. Replacing Forth with Java would ease this problem considerably... If Mitch Bradley won't like it, tough! It was a pipe dream for many reasons, but a fun one.

It would be great to tackle a project in Java, but with my current work it's hopeless. I can't even complete a 1000-line patch to usbmon for a month.

yum is slow

I have a 500MHz P3M laptop, which is running yum at 96% CPU and ate 29 minutes of CPU as of this moment [as I was typing this entry, yum ended its thinking and started downloading headers]. I remember times, around FC-4 or so, when everyone was complaining about yum being a memory hog. On this very system it would balloon over 200MB and thrash badly in my 192MB of RAM. Apparently Seth Vidal (or someone) did some radical surgery, because my yum's RSS is 13MB now (on top of modest 24MB total). While in awe in front of this masterful achievement, I have to ask if his main technique in getting yum's bloat under control was to throw away cached structures and recompute stuff.

But what am I doing using a 500MHz laptop? I suppose it's a good question, but on the other hand the poor thing seems to run GNOME with no big difficulty. Its main downside is the 16 bit color. And the battery is dead. Also, 9GB winchester is getting kind of tight... Oh heck who am I kidding. I need a new laptop.

Woops Groups

I boasted in comments for an entry at Astro's how I did 3" groups with my short Mosin (I have a cut-down known as "Model 59" in America). Since I had 5 rounds left from the season, I took it with me to the range today, with explicit purpose to take a picture of the group.

As a result, I'm having a crow for supper tonight. The orange circle is it. The problem is, I started flinching badly; even caught myself closing eyes. For comparison, the green circle is set around 10 shots from my 5.56 Browning, for which I wasn't straining too much.

BTW, it looks like I wasn't to the range for about a year. I went through the door where office used to be, and a club staffer explained that the office was relocated 8 months ago. I blame anime.

LJ trust metrics

Raph linked to Bitchun by Joseph. Joseph knows math of eigenvector and carries the torch of trust metrics, so to speak. When we touched bases some time ago, I was somewhat disturbed by his [very] premature attempts at commercializing the research. I know only too well what happens when premature commercialization strikes (Anyone remembers Matt O'Keefe and GFS? Me neither). Joseph is too smart to fall into his trap though, I did not even need to tell him about the danger.

Raph's link prompted me to surf a little bit, so I found this:

It's a picture made by the same guy who applied PageRank to LJ. I gave that a whirl as well. The results were well calculated, but mostly useless. For some reason I do not find popular people's diaries all that interesting. Also, it unearthed a pile of folks who used to write years ago and moved on. The lonely catch of the day was ajaxxx. I have to pay attention to X11 due to this Xen and PV framebuffer business.

{Update: Oh, and BTW. The picture above is a good illustration to the thesis that one ought to blog in English.}

Yokohama Kaidashi Kikou

I saw the two OVA episodes of YKK. Of course I had to, considering the impact of the parent manga.

The OVA is very faithful to the manga, especially in the art, but overall it feels as if the creators were afraid to make the anime. It does not disappoint, because it's exactly what I was expecting. The right adjective would probably be "weak".

I am not quite sure what to blame for the lack of punch, because, for example, both Azumanga and Naruto (up to ep. 136 or so) are very closely aligned with their respective mangas and they are tremendous successes. Maybe trying to retell the story in two episodes without changing anything was hopeless. The whole thing seems overcompressed.

Probably what an ideal YKK anime needs is a Japanese Peter Jackson (and his budget).

Second episode tries to deliver on the subtle post-apocaliptic feel in the very end, which was the main thing going for the manga. It kinda sorta succeeds if the viewer feels generous.

Liked: It could be worse
Rewatch: No. Re-read the manga instead.

Google imitates LiveJournal

I suppose it must be the most sincere form of flattery, but Google started to integrate Orkut with Gtalk. So far though, Gaim does not seem to pick the new connections added through Orkut, although their web applet does (even after restarting). Also... They use a Flash applet to set a JavaScript variable. If that sounds too crazy to believe, look at Control-U and gtalk001.js. I suppose I'm lucky my browser hasn't crashed yet.

{Update: In the morning, Gaim started updating, after a fashion. New buddies are added to a default group, so I have to drag them where they belong one by one.}

{Update 2006/11/10: They add buddies with e-mail addresses which are registered with Orkut. But they are NOT the addresses used for jabbering! They should've used the sign-in name for Orkut and gmail.com domain, or else this won't work.}

Atom feed for Advogato

Regarding Advogato, Steven writes (in comments for an article):

I got a little carried away yesterday and decided to add support a few more feed formats than I'd originally intended. Zaitcev's feed uses Atom (thanks for volunteering as a test subject, by the way!), so that's first on the list. A few other people have set up a feeds too, so I have sample data for the common RSS formats (v0.91 and v2.0). And one feed was in the somewhat more complicated RDF Site Summary format (aka RSS v1.0). Looks like all of them will work out okay so far. After parsing all these formats, I can see why Atom is becoming so popular.

Since I'm only a kernel monkey, I'm utterly ignorant about the merits of Atom. I subscribed my Advogato feed to Atom because Siebermann wrote once:

The difference between Atom and RSS is that Atom has a real specification, one good enough that people actually write to it. So I can use the specification to write a useful feed generator [...].

Type 64 bis

Having a rotating banner is one thing which I cannot do at LJ. In this instance, Steven uses it to a good effect to display a Type 64 rifle:

I wrote about Type 64 before. Since then, I've read that Japanese brought it with them to Iraq. The reports by Americans weren't very complimentary. The gun is quite heavy, the bipod clicks and clacks to give out your position, ergonomics are dubious overall, clip is short. It is, however, reliable. Sounds just like something Russians would make, if they didn't hit upon the goldmine of AK.

Halleluya! grep works again!

In FC6, grep works again: running "grep foo" is only 60% slower than "LANG=C grep foo". It used to be 20000% (twenty thousand percent, or 200 times) slower. Not a day too soon, I'd say. I was getting tired from typing LANG=C in front of every goddamn xargs. It would be awesome if the remaining 60% regression could be addressed, but let's be realistic. Now if only someone designed a UTF-8 locale which did not screw the ordering files in ls output...

Futakoi drowns itself, Tenshi no Shippo

This is a harem week. I have just finished Futakoi, and by the end I started thinking "I could have watched Lain instead". Same tiring effort, but at least I'd see some classic. Who knew that it's going to be such an unfun run? Meanwhile, half of Lain sits in its store wrapper.

Futakoi started dumb as a post and had me rolling eyes a lot. The harem man, Nozomu, is utterly indecisive, and the only thing he is capable of doing is to ride his luck. However, I remembered that Mahoraba's lead was pretty bleak in the begining and stuck with it. I could have dropped the show even after that, but around the ep.7 the story abruptly turned from slapstick comedy into romance and drama. So I hoped for the better, only to be rewarded by a trainwreck ending which does not resolve any plotlines.

Of Tenshi no Shippo (Angel Tales in R1 version), I only saw one DVD. It starts as dumb as Futakoi, although the comedy is somewhat more easy-going and memorable. For the taste of it, I remember one moment when The Goddess, in her infinite majesty, reveals a Live CB (Crystal Ball) transmission of Goro fighting off his guardian angels as they attempt to undress him -- ostensibly for the purposes of hygiene. The idiocy of observed scene does not faze observers one iota, and they remain in the Goddess' bliss while the little image of Goro in the CB struggles to save last shreds of his battered dignity.

I fully expect Tenshi no Shippo to make a turn once the setup is done and start telling the story, but there's no telling if it's worth watching. Futakoi certainly wasn't.

Liked: Not violently against it, but it's no Mahoraba
Rewatch: No

{Update: I forgot to mention that twins make Futakoi's love dodecahedron harder to digest. They look exactly alike, but do not behave the same. I resorted to sketching a basic map with little tags for each character and arrows for love interest. Specifically, Kaoruko has a tail, whereas Sumireko doesn't (she is pictured above). Yura combs her hair to the right, Kira combs to the left. I can't help it, I'm dense.}
