Alive.
June 4th, 2013Just busier than a one-legged man in a butt kicking contest.
I did get to shake Larry Wall’s hand and say thanks to him. (For those of you who are not Perl people, this is like an observant Jew meeting Moses.)
I also got to spend some time with Bill “whump” Humphries, who was in town presenting “Perl Meets Modern Web UI”. I thought it was a great talk, but I’m biased: I’ve known Bill since our days in the CIA spying on student organizations at the University of Texas, though I haven’t seen as much of him as I’d like in the past few years.
More as time permits. The “Hack Your Mac With Perl” talk is about to start.
Stuff and things.
June 2nd, 2013Last week was not a good week. This coming week is shaping up to be pretty hectic (though I am hoping not as personally unpleasant), so there may be a blogging slowdown.
I spent all day yesterday at the 2013 edition of the Texas LINUX Fest. I haven’t been since 2010, but that had less to do with my frustrations with the 2010 organization and more to do with personal issues. (In 2011, that just turned out to be a bad weekend, with having to get my car inspected and deal with other things. Last year, it was in San Antonio; while that may be a welcome change of pace, the schedule wasn’t compelling enough to make me drive 150 miles round trip.)
I thought about doing detailed summaries of each session I attended, but frankly I’m a little worn out and a little lazy. I’d rather mention a handful of panels I did like. (There were some others that I went to, but don’t feel I can fairly evaluate because they weren’t what I was expecting, or I was distracted by other issues (see below), or, in one case, I just think it’d be a jerk move to badmouth the presenter.)
I really enjoyed Theo Schlossnagle’s “Scaling: Lessons Learned and Their Applications to Apache Culture” keynote speech, which covered a lot of good points about complex systems. He sees commonalities between building scalable systems and building communities to support them. Many of the points he made may not be hot news flashes but are worth repeating. Among those:
- People get so caught up in how awesome it it to build stuff that they forget what the real world looks like.
- Code is just a tool. It isn’t a child or a family member. You don’t have loyalty to it.
- Engineers have a tendency to focus on the technology they love instead of the actual problems they face.
- At the core of things, your job is to tell the computer what to do.
- Unbalanced hyperspecialization leads to poorly constructed solutions.
- The biggest challenge is that increasing scale and increasing performance demands lead to increased complexity.
- Technological complexity is an emergent property of complex and changing business problems. This complexity has to be understood and managed, which is difficult for specialists.
- If you don’t provide value, your [stuff] doesn’t matter.
- In order to survive, we need generalists. Schlossnagle didn’t quote Heinlein, but he might as well have.
David Stokes from Oracle did what I thought was an excellent talk on “The Proper Care and Feeding of a MySQL Database”. I’ve mentioned before that I’ve been dabbling in MySQL, so I got a lot out of this. Some of it may have been obvious (more RAM, more disks, good things. Use decent hardware, not something you scavenged from the admin assistant because it was too slow to run the latest Office), but the two things we learn from history are that too many people don’t learn from history, and that the obvious often isn’t.
Philip Ballew’s “Ubuntu; Where We Were, and Where We Are” presentation was…amusing, shall we say, mostly for the level of skepticism directed at Ballew from the audience, many of whom seem to be skeptical about recent Ubuntu decisions like the replacement of X. I’m becoming increasingly skeptical of Ubuntu myself; I just upgraded to 13.04, and now I’m running into the “The system is running in low-graphics mode” error, which I haven’t had time to fully debug. The worst part is that I’m getting this only intermittently; I think it may be a timing issue, possibly with some Virtual Box kernel extensions.
Owen Delong’s “IPv6 – It’s Easy on LINUX” presentation was also very good. I haven’t even started to configure my systems for IPv6 (and I’m not sure everything supports it: I’m sure about the Mac and Project e, but less sure about some older gear), so I found Delong’s talk useful. I was surprised, though, that there was even more hostility and skepticism from the crowd than there was at the Ubuntu panel. Why is IPv6 an issue in 2013? And many of the questions from the crowd seemed to boil down to “How do I emulate this particular thing I do in IPv4 using IPv6, even though the reason this is needed in IPv4 is because we have a limited number of IPv4 addresses available, where in IPv6 we could give every single atom in the universe a unique address and not run out?”
Okay, that was a long question, but you get the point.
Brad Richardson’s “GPU based password recovery on LINUX” lightning talk is worth checking out. He was able to do the talk in about five minutes, instead of the allotted ten, and the subject is interesting; using reasonably priced GPUs, you can rapidly break MD5 hashes, orders of magnitude faster than throwing a general purpose CPU at the problem. (Richardson’s slides give specific performance figures: try 16 hours 46 minutes to brute-force a “8 character password with lowercase, uppercase, and numbers”, versus an estimated 36 days for a CPU based attack.)
Anyway. Tomorrow is the start (for me) of Yet Another Perl Conference 2013. (I registered for the conference itself, but couldn’t afford any of the training going on over the weekend or after the conference. Plus the training conflicted with the LINUX Fest.) I expect to be pretty tied up Monday through Wednesday, though I will try to blog from YAPC as downtime and network connectivity permits. I may even try to blog YAPC 2013 itself, but I can’t promise that.
Edited to add: Why did I not have a “Perl” category on this blog, but did have a “Python” category, given that I use Perl more often than Python? Fixed.
Edited to add 2: Thinking some more about it, it made sense to have a “Programming Languages” category and make Perl, Python, and others sub-categories below that. I’m still thinking about whether it makes sense to put the languages category under “CompSci”, but that way lies TJIC madness.
Edited to add 3: I realized there were two other points I wanted to make.
- I was much more favorably impressed with the organization of TXLF this year than I was in 2010. Of course, they’ve had four of these, so you would expect them to have the bugs fixed. Still, I was impressed at how smoothly almost everything from registration onwards ran. The only problem I saw was an unexplained 20 minute delay in the start of the lightning talks, but I didn’t feel that was a major issue.
- The quantity of tchotchkes available at TXLF? Very high. The quality of tchotchkes available? Still evaluating that, but I’m decently impressed. Favorites: the microfiber cleaning cloths from OrangeFS, and the SavvisDirect USB/12V adapters. Special mention goes to Hostgator, who were giving away a much wider variety of tchotchkes than any other single vendor.
Bad week for the APD.

May 31st, 2013Obit watch: Catholic priest and author Andrew M. Greeley.
Also:
I was not aware of this. What a lousy way to end your life.
Also: LAT obit for Jack Vance.
Police have made an arrest and filed charges in the case. The twist: the accused is a deputy sheriff.
The law of unintended consequences, continued: the city of Austin banned single-use bags effective March 1st.
(It is worth pointing out that reusable bags were common here even before the formal ban, and that there are no actual statistics as of yet showing an increase in shoplifting.)
Said it before. Say it again.
May 30th, 2013If you’re going to scam, make it worth your while. Seven figures in front of the decimal point is a good start.
Don’t lose your job as a police officer for something stupid, like trying to scam free movie tickets.
(Especially at the Regal Westgate Stadium 11. But, as I’ve said before, I’m an Alamo Drafthouse snob.)
Please excuse me. I’m having an Ambulance Driver moment.
May 30th, 2013From the Austin American Statesman:
It isn’t clear to me exactly who these “Travis County officials” are. However:
Is there any evidence that these decisions compromised patient care?
Let us consider some of the situations in question:
That’s six out of how many?
Let us talk about specific incidents.
This is kind of useless without knowing the actual transport time, as opposed to the 30 minutes without traffic estimate. I’m not an EMS guy; what I know about EMS I’ve picked up from reading AD’s blog and listening to “Confessions of an EMS Newbie“. But I’d be willing to bet that by the time you get STAR Flight dispatched, it gets on scene, you get a safe landing zone cleared, STAR Flight lands, loads up, leaves and gets to the hospital…you’re probably looking at close to 30 minutes, at least.
Again, note that there’s no indication that anyone believes patient care was compromised by the decision to use ground ambulances instead of STAR Flight.
Man. Sick babies. That’s terrible. And 45 minutes to get one to a hospital?
Oh. So it was actually 25 minutes to get the baby to the hospital, not 45? And it sounds like the first 20 minutes were probably evaluating the baby’s condition and stabilizing it for transport.
(Again, no suggestion that patient care was compromised by taking 25 minutes instead of…well, how long would STAR Flight have taken, under those circumstances?)
Now this is interesting:
This is a place where I’m on Ping’s side, and the side of the paramedics. As you know, Bob, I’m very much in favor of letting the guys in the field make decisions. If their decisions about whether STAR Flight is appropriate are being overridden because of decisions by some automated system, then let’s review that. But:
And, hey, who doesn’t love a cool helicopter ride? Buried in the final few paragraphs of the Statesman article is one good reason why paramedics may not want to call out STAR Flight:
Can I point out that you can get a decent used car for $7,500? Can I also point out that if I do some rough calculations based on someone I know who lives outside the county being STAR Flighted to UMC Brackenridge, I come up with a rough estimate of $8,945 for the trip? (I’m figuring about 17 miles by helicopter at $85/loaded mile.) At $20/month, they’d have that bill paid off in 447.25 months, or 37.27 years.
So that’s reason one why EMS may not want to use STAR Flight if patient care isn’t compromised; because it is freaking expensive.
Reason number two: helicopters are dangerous compared to ground transport. Kelly Grayson has been sounding alarms about the overuse of helicopters since I first started reading his blog, and that was a long darn time ago. Quoth the man himself:
Going back to that lightning strike in Bee Cave, I don’t remember what the weather was like that day, but I suspect it was pretty sorry if people were getting stuck by lightning. Doesn’t do a whole lot of good to transport people by helicopter to get a better outcome if your outcome is that the helicopter is forced down by weather and everyone onboard dies.
That happens. More often than you might think.
So are “Travis County officials” worried that patient care is being compromised by paramedics avoiding STAR Flight? Or are they more worried that STAR Flight is not being used enough to justify the cost of maintaining it, for what may be very good reasons? You make the call.

Random notes: May 29, 2013.
May 29th, 2013The NYT is absolutely indignant that the ceremonial throwing out of the first pitch at baseball games has evolved from a…
In other news, water is wet and fire is hot. More:
Question left unanswered by the paper of record: do the ceremonial second, third, fourth, and fifth pitches cost less for the sponsors than the first pitch?
Also in the NYT: Antoni Krauze, a Polish film director, is working on a feature film called “Smolensk” about the 2010 plane crash that killed the Polish president and 95 other people. But “some leading Polish actors have refused to participate”, and the NYT sees this, and other events, as reflecting deep divisions in Poland over the crash.
Band in Austin.
May 28th, 2013Well, this is interesting: Nike is ending their relationship with the LiveStrong organization at the end of this year.
Thoughts:
- I wonder if LiveStrong wristbands will become collectable. I kind of doubt it, since “the Livestrong Foundation made more than 87 million of its Livestrong yellow rubber wristbands since May 2004”. But you never know…
- I was wrong, wrong, wrongity wrong! Just have to get that in there.
- Can anyone think of a faster and more spectacular public collapse than this one? Maybe Paul Christoforo or Judith Griggs, but those folks were only Internet famous, not real life famous.
Things pretty much broke at the end of last year, so I’m wondering what 2013 to date sales are like. Probably not great, which might explain Nike and Dick’s being ready to “give up the business”. On the other hand, I don’t have a real high opinion of Dick’s, so it wouldn’t surprise me if other factors were involved.
Scanners live in vain!
May 27th, 2013A comment by friend of the blog Jake over at Curses, Foiled Again led me to check out the Broadcastify web site. I think this had been bubbling somewhere below the surface of my conscious mind anyway, but Jake provided the kick I needed.
Broadcastify basically collects radio feeds from scanners and organizes them by location. So you can browse the site, find your local area, and (assuming Broadcastify has a feed) click the bunny to listen to your local police or fire department traffic. There are several player options, including web-based players as well as iTunes, Real Audio, Windows Media, and Winamp.
Not every locality is there; there are some large gaps in coverage for Texas, to take one example. There are feeds for Williamson, Hays, and Bastrop counties; however, there’s no feed for the Williamson County Sheriff’s Department or Round Rock PD. On the other hand, this is free, and you get what you pay for.
For reference purposes, here’s the Travis County feeds page, which includes Austin/Travis County Fire and EMS and Austin Police and Travis County Public Safety.
Back a long time ago, I was an avid shortwave and scanner listener; I still have the equipment, but my scanner isn’t capable of following the newer trunked radio systems. I’ve flirted from time to time with the idea of purchasing a newer scanner, but now I don’t have to.
Thanks, Jake!
More on Kimber and LAPD SWAT.
May 25th, 2013Last August, I noted an LAT article about allegations that LAPD SWAT members were purchasing specially made and marked LAPD SWAT Kimber pistols at a steep discount and reselling them on the open market. At that time, it was unclear if this violated any regulations or laws; LAPD conducted one investigation, which was badly botched, and had just started a second investigation when the LAT ran their report.
Today’s update: the investigation has expanded to include LAPD’s Special Investigative Section (SIS), who also had custom Kimber pistols made for them. And the FBI is involved.
Yeah, I remember the Kimber SIS guns. I thought they were kind of neat looking, but:
- I need another .45 like I need another hole in my head. Not that that stops me from looking and drooling, but
- I already have one Kimber (from prior to 2000), and…
- This was the period when I heard bad things about Kimber’s quality control, especially on the smaller guns. (I understand the person who was in charge at Kimber during this time has since left and gone over to Sig Sauer. I don’t know if Kimber’s QC has gotten any better.)
Yeah, see my previous entry for more details on the LAPD SWAT gun. As for the SIS gun, here’s an example from GunBroker. N.B.: I am not the person selling this, I have no connection to that person, and the GunBroker link is for illustrative purposes.
I’m sorry. Did the LAT, which has been calling for more gun control, just refer to Federal gun laws as “arcane” and “complicated”?
And here’s a small note that amuses me: this month’s American Handgunner (July/August 2013) has an article on the new LAPD SIS gun: the Glock 30S, which was custom built for LAPD SIS, but:
More from the Glock website. I suspect this won’t be quite as controversial as the Kimber, only because Glock seems to have eschewed adding the “SIS” logo to the slide.
(And is there anyone out there who can explain to me why Glock’s .380 pistols are law enforcement only?)

May 24th, 2013Obit watch: Steve Forrest. NYT. A/V Club.
Forrest knocked around movies and TV for a long time, but he is perhaps most famous for this:
I am not ashamed to admit: I loved that show when I was a kid. And I still think it has one of the greatest themes ever, right up there with the original Hawaii 5-0 and Mission: Impossible.
NYPD blues, part 1:
Part 2:
That part seems easy to me. In the wrongful convictions I’ve read about, a recurring theme involves the wrongfully convicted being offered a chance at parole, and being turned down or refusing because they are expected to admit their crime and show remorse. If you didn’t do the crime in the first place, but you’re offered a shot at getting out of prison, do you maintain your innocence even if it costs you that chance? Or do you tell the parole board what they want to hear?
Consumer note: Pocket Hose.
May 24th, 2013You know the Pocket Hose, right? Extensively advertised on television?
My mother moved into a smaller place at the end of March, and bought a Pocket Hose around that time so she could water her plants without bucking around a big garden hose.
It lasted about two months. The hose now seems to have some sort of internal break such that, instead of water coming out the nozzle, it flows out from just below the faucet connection. It isn’t leaking at the connection, like it is improperly tightened or missing a gasket, but leaking in the hose portion below the connection.
Of course, this being cheap Chinese made crap imported by Telebrands, it doesn’t have any kind of warranty. Luckily for her, she bought it at Home Depot with her Home Depot credit card, and they’ve agreed to refund her money when she brings it back.
Seriously, guys, less than two months? Put that in your social media pipe and smoke it.
And just in case you think I’m being a crank, it sure looks like the Amazon reviews support my position.
