Hi, all. My name is Drew Erny. I'll be graduating in May of 2016 from the University of Alabama with a degree in Computer Science. My last job was interning at Red Hat and working on identity management software, which has given me a solid base in security and cryptography. I also have a decent amount of experience working in Ruby on Rails.
I'm very early in my career and right now I'm looking for a close-knit team with a mostly in-person office. I have a lot to learn and I think the best way to learn it will be working elbow to elbow with the experienced developers at your company.
If I sound like your kind of developer, or you know someone else who would be interested, shoot me an email.
Location: Tuscaloosa, AL
Remote: No (generally, but would consider remote)
Willing to relocate: Yes, please relocate me.
Technologies: Mostly web, security, and cryptography

Diesel isn't a fuel type, it's an engine type. What we call "diesel fuel" is really just fuel better suited for burning in a diesel engine than gasoline. We also have techniques for refining some hydrocarbon chains into different ones, which means we can focus production on one fuel type.
The engines are designed quite specifically for the type of fuel that will be burned in them. Although technically you could make a diesel engine that would burn normal petrol, it would not be advisable to put normal petrol in a diesel car, because the engine relies on the fact that diesel is a better lubricant than petrol. Also, various components (such as fuel filters, fuel pumps, etc) also depend on the fuel being of a certain type, and would be damaged or otherwise fail to work with the wrong fuel.
The bigger problem (other than lubrication) is managing the moment of detonation. Petrol would explode way too early in the cycle of injection, that's why it will damage a diesel engine.
In a diesel engine, only fresh air is in the cylinder during the compression cycle. At the top of the compression cycle, that's when the fuel starts to be injected and immediately burns/explodes. There's other reasons why petrol in a modern diesel engine wouldn't work, but i don't think pre-ignition/detonation is one of them.
"Throttle" in a diesel actually controls for how long the injection takes place.
But the fuel injected does not detonate immediately, it is allowed to spread out a bit and the chambers are shaped to channel the detonation. It's a short interval but it is an interval. Injecting gasoline at those pressures and temperatures would mean instantaneous detonation of the fuel injected, too early in the cycle which will cause damage (to the injector, and to the crankshaft and/or pushrod bearings because they'll have to deal with more force than what they were designed to cope with because the energy is liberated in a much shorter time-frame). At best this will cause severe degradation of engine life, at worst immediate failure.
Another issue is that the injectors are carefully shaped to deliver a mist of fuel and the properties of gasoline and diesel are sufficiently different that the droplets will be of the wrong size and won't separate cleanly from the injector before detonation occurs.
All in all, not something you want to experiment with so if you find that you've 'gassed up' your diesel vehicle better drain the tank instead of taking your chances.
In winter in Canada it is common to put about 5% gasoline in the diesel fuel to overcome temperature effects on the diesel fuel.
As someone who lives a few blocks from where this complex is going up, I don't know what these people are smoking. $3000 for 360 sq foot apartment is utterly absurd, even in NY. I pay far less than that for a nice apartment in a doorman building so I don't know who would in their right mind would pay for these. I could see _maybe_ paying if this complex were going up in a prime neighborhood like the West Village or Tribeca, but way over on 27th street which is a half mile (which is considered far in Manhattan) from the nearest subway station, no way.
The whole place. It works out. It's an exception to an assisted living community, so it means I have to stick to 3d printing and laser cutting if I use the shop tools after 6PM or so, and occasionally I have to help an old person carry stuff, but it's nice. I don't even lock my front door.
I'd have to say you lucked into a pretty special deal and not representative of much within 20 minutes of SF (and is that 20 minutes at midnight or during rush hour?). :-)
After reading that they had to waive the regular zoning laws, I get the impression that this is a developer's approach to fulfilling an affordable housing requirement while actually trying to push median rents upward.
I've known the answer to the Monty Hall problem for a long time, but this particular explanation just so happens to be the first one that's brought me closer to grokking the answer. I dunno what's different about this one, but it makes sense to me. Congrats.
I think that the key sentence in his explanation is "So now Set B still has a 2/3 probability of having the prize." This really nails the whole thing down.
I mean, this is server hardware. One of the major differences between server hardware and desktop hardware is build quality. I've got a ten-year-old 1/2U rack server sitting in a closet that I bought for pennies at a surplus auction that still runs great.
We will probably have to wait 30 years to really know.
FWIW, lots of hardware from ~30 years ago still works. I have a 27 year old Amiga500 that still boots fine (many of the floppy disks have become unreadable, though).
You can buy fully working vintage computers much older than that on eBay.
Yeah, but you have to be very, very good to get one of those internships. I'm a mid-top tier programmer (better than most of my cohort) from a modest state university. I've been applying everywhere, and there's no way in hell I'll make close to $20k. I'm pretty good at what I do, but there's a gulf between what you get if you're good and what you get if you really good.
Don't sell yourself short. I am a fairly average programmer coming from a state school, and I made 1800 a week plus housing last summer, and am going to be making 2000 a week plus housing this coming summer. If you are really a mid-top tier programmer opportunities like this and better will be available to you.
This argument is as terrible as it is old. Feminists have been fighting for the right to work in coal mines, and fight on battlefields, and everything else.
>Feminists have been fighting for the right to work in coal mines, and fight on battlefields, and everything else.
It's terrible because it doesn't fit the narrative you're trying to push. Paying occasional lip service isn't the same as "fighting for the right". Working in a coal mine or fighting in the battlefield isn't a "right". It's an obligation blue collar families fall into.
That said, from within Silicon Valley it sure looks like the feminists are coming for the supposedly easy money of engineering while ignoring the risky things like policing. True or not, it's sometimes the perception that matters.
From what I gathered, the idea was supposed to be that when fighting broke out, the hostages would know that the fighting was a rescue mission and be able to act accordingly. Imagine if there was just suddenly fighting, with no context; hostages would /know/ the FARC was on edge and would be extra careful not to try anything stupid and get killed. However, with this message, they would know that the fighting is a sign of a rescue mission and try to escape.
FARC hostages had no room to act when there was fighting nearby; I read Betancourt's book about her captivity and the first thing the FARC would do is to put a gun to their heads (literally or figuratively, can't remember) with orders to execute them if the army came close.
> However, with this message, they would know that the fighting is a sign of a rescue mission and try to escape.
What makes you think that a sign of a rescue mission means that you should try to escape?
If anything, popular culture teaches exactly the opposite. Think of any Hollywood movie involving a bank robbery or hijacking. The hostages lie down and duck while the police swarm in and shoot the bad guys. The hostages do not try to escape.
I'm not saying which is better (staying put vs trying to escape), and I don't know.
I'm saying that the message--"19 people rescued. You are next. Don’t lose hope"--is useless and open to whatever interpretation you desire.
Popular culture in a country at war is probably going to somewhat differ from your personal experience where Hollywood is a primary authority on conflict. These hostages would have context you're probably missing.
Yes, you read the article. But the hostages didn't!
All the hostage heard is "19 people rescued. You are next. Don’t lose hope". How does a hostage conclude "you should try to escape" from the preceding message?
The hostages were mainly soldiers of the colombian army who had been fighting against the FARC's guerrilla tactics for a long time. There are many hostages, held at different locations throughout the jungle by different captors. And they just know better than you and me, no need to read any article.
Now, the message is not a call to direct action because there is no possible action that would benefit all hostages getting it. It's just providing them hope and information (we're busting our assess off on active operations, so if something makes you think we're coming or around, there's actually a good chance we are). Do as you see fit if/when that happens.
Also, your whole reasoning is fairly solid, but you are building it on top of a wrong context. The hostages are not the average american and the captors are not the bad guys from a movie. Your popular culture is wildly different than the cultures of the involved parties. You should get that straight before making any reasoning using your own context instead.
This is really, really clever. I mean, I guess it could be obvious to some people, but I tend to over-think things quite a lot and probably would have never come up with such novel uses for radio-buttons and check-boxes.
Definitely going to be keeping this in mind next time I'm working on a web application.
I'm very early in my career and right now I'm looking for a close-knit team with a mostly in-person office. I have a lot to learn and I think the best way to learn it will be working elbow to elbow with the experienced developers at your company.
