Heck, these days performance seems to be dominated by lock contention, given the distributed nature of everything.

This, totally this.

I just rolled 40 years in this ridiculous industry, and the one thing that keeps coming up over ... and over ... and over again is that the total throughput of a system is often controlled by one or two locks / blocks (thread/process, disk, network, ear wax, etc.) buried deep, deep inside. You can micro-optimize code to your heart's content, but when you finally get around to profiling what's actually happening in the system that didn't scale from 100 hits/sec to 1000 hits/sec (or whatever) you arrive at an "Oh, shit!" moment when you realize that an assumption you made 6 months ago (Hey! This will never be a problem.) is now biting you in the ass.

United States Begins Flying Stealth Bombers Over South Korea 567

skade88 writes "The New York Times is reporting that the United States has started flying B-2 stealth bomber runs over South Korea as a show of force to North Korea. The bombers flew 6,500 miles to bomb a South Korean island with mock explosives. Earlier this month the U.S. Military ran mock B-52 bombing runs over the same South Korean island. The U.S. military says it shows that it can execute precision bombing runs at will with little notice needed. The U.S. also reaffirmed their commitment to protecting its allies in the region. The North Koreans have been making threats to turn South Korea into a sea of fire. North Korea has also made threats claiming they will nuke the United States' mainland."

Festo's Drone Dragonfly Takes To the Air 45

Posted by samzenpus
from the little-flyer dept.
yyzmcleod writes "Building on the work of last year's bionic creation, the Smart Bird, Festo announced that it will literally launch its latest creation, the BionicOpter, at Hannover Messe in April. With a wingspan of 63 cm and weighing in at 175 grams, the robotic dragonfly mimics all forms of flight as its natural counterpart, including hover, glide and maneuvering in all directions. This is made possible, the company says, by the BionicOpter's ability to move each of its four wings independently, as well as control their amplitude, frequency and angle of attack. Including its actuated head and body, the robot exhibits 13 degrees of freedom, which allows it to rapidly accelerate, decelerate, turn and fly backwards."

ROFLCOPTER! Being the Geezer Geek® in our family/neighborhood I get the calls for ... almost everything. I had one woman (who shall remain nameless (except she's my older sister)) who complained of all sorts of horrible things happening. Turns out it was an out-of-disk and there was a huge number of ~whatever files all over her filesystem. Cleaning them all up gave her about 40% free disk.

Webfaction.com - $9.95 monthly (cheaper with longer commitment).

Run by serious techies. Nginx as a frontend-server, Apache/whatever you want on the backend. MySQL, Postgres, whatever for a DB. Python (Django is a one-click install), Ruby, whatever. Long-running processes. Cron jobs. Better-than-average admin panel.

All in all, a great hosting company for smaller sites.

I'm not a shill, just a happy customer. I have several customers' websites there.

When we bought our house (2003) the guy helping me thought I was insane to pull dual CAT5e to each room for phone/data (we have a great crawl space) and 8(!) CAT5e to my new, detached office. But we're in Sebastopol, CA (in Russian, Sebastopol means "gopher") and the little f*ckers have already chewed into the Schedule 40 PVC conduit and destroyed 4 of the 8 CATe cables.

You can never have too many extra cables / conduits. Cable is cheap, retrenching is expensive.

One step beyond this: Use Ultra VNC's Single Click mode (free). Set up the config file to automatically connect to your listening VNC port. I've fixed email in Paris, my sister (and her machine) in Tucson, and a niece in Sydney, Australia. All they do is download a 200KB EXE file from my website. I even have Office 1 and Office 2, so if I'm in my wife's office they just click on that. The whole thing takes less than ab out 30 minutes to setup and no one else ever has to deal with anything complicated.

This.

My wife and I have dealt with all 4 of our parents passing away, and the one thing that is certain is that as soon as the bank/brokerage/whatever knows that the primary account holder is dead, they go hypervigilant. Either have the various accounts and safety deposit boxes in joint ownership, with rights of survivorship, or have unambiguous beneficiaries set for all for your/their accounts.

The courts can take months or years to get things straightened out, but if you need the money to keep paying the mortgage on their house you may not have that much time.

One last thing, make sure that they have given Medical Power of Attorney and Full Power of Attorney to one(!) trusted child / friend while they are still legally competent to do so! Almost worse than losing your parents altogether is watching a 6-way train wreck happen as people begin fighting over the spoils ... before there are any spoils to fight over.

It can get ugly. Be prepared.

Comment: Ahhhh, Pick! (Score 4, Interesting) 377

The most over-the-top DB God I know started in Pick-land (ca 1972?). Although he does (is forced to?) use SQL nowadays, he thinks in ways that do not come out of any SQL DBA handbook. As a result he gets DBMSs to do things that are ... unnatural.

He is currently doing some data-cubing stuff for us that I didn't think could be done with something less than a DOD budget. He says his touchstone is thinking in Pick and then 'translating' to SQL.

I still think that the 2 missing courses from any CS degree program are 1) how to debug, and 2) history of computing.

Does the name Pavlov ring a bell?
