You can make user level systemd instances run at startup and stick around regardless of login/logout. loginctl enable-linger <username> This enables some nice deployment strategies that don't require root.

Not a brag--just wanted emphasize how straightforward and fun something like this can be.

It would probably be worth it to temporarily define one of the reserved opcodes as putchar.

Sure. I aim to have our interview cycle take under a week, although in honesty, I think it takes about 10 days. I often take on a little more work myself (especially in the phone screen) if I believe it helps speed up the process and saves

LuaJIT adds another massive speed-up on top of the already healthy Lua performance. http://luajit.org/performance_x86.html http://luajit.org/performance.html That said, I do agree that Lua can be more cumbersome than Python or Ruby.

Let me start by asking $15k/month in revenue or profit? Do you have capacity to hire? Courting investors is a full time job, but so is hiring if done right. You probably can't do both with just two of you. If the goal of raising money is

We often (jokingly) measure time in kiloseconds around my office. As rue points out, that's just a bit over fifteen minutes, so its actually a useful unit. "See you in the conference room in 2 ksecs..." Put a bunch of geeks together too lon

Perhaps you're thinking of a different phone? I believe the Optimus T/S/V line all have capacitive screens.

I have an LG Optimus T on T-Mobile. I got it a while back for $200 with no contract. My $60 plan through T-Mobile is more expensive then the Virgin one mentioned in the article, but because T-Mobile reduces your bill if you don't take the p

The biggest loss here is the Mac specific GUI bits. Not only does Apple Java use native drawing primitives for ui (instead of requiring X11 like some ports), it also doesn't look completely horrible. Unlikely as it is, I wish Apple would up

Remember, it's basically only Linux distros that have the capability to upgrade a third-party library like that (ironically, distro maintainers actually have the source code required to recompile everything if they wanted!). Mac and Windows

Every process has "my-actor" defined in its global environment. It provides methods related to basic actor functionality. In this case I'm calling the "announce" method to say something to all of the process' subscribers. user-interface and

We don't build any in, but the same strategies (ie, requiring a license key, etc) that work for regular applications like Microsoft Word also work for fluid applications. The bits can be copied easily, but the same is true for traditional s

You can build message passing code that suffers from race conditions. In practice, though, it's almost always obvious if you're about to do something dangerous. On p.173 Joe writes: When we say things such as this: Pid = register(..

Hi nivertech, I'm sharing one of the lessons we learned building our own programming language. I love how many language designers there are on HN! We're working on an invite system, so everyone can benefit from Skynet! Skynet is better when

True, the nice things about libraries is that they can compete and make your ecosystem stronger. But the nice thing about building it into the language is that it becomes a common layer of compatibility. We've gotten comfortable enough with

I actually spent some time reading that spec yesterday while hunting a bug. I was trying to figure out if maybe we were violating the protocol in some way. I'm not enough of an expert to weigh in, but the spec did make me chuckle. Super ver

I loathe source code templates. To use web (newspaper?) terminology, it puts the content below the fold. It also raises the cost of factoring code out into its own file. Even a simple code header can easily be double the amount of code I co

And in fact they almost certainly will choose a different host. Our plan is to just buy an extra IP for one of our VPS machines and leave it unused.

We're experimenting with this technique in our peer-to-peer software. Unfortunately we probably won't have data on what percentage of the time it works for a few weeks. Provided everything goes okay, I'll try to post our data as a follow up

Haha, well, we were also in a pool with a ton of other brilliant, driven applicants! That might have had something to do with it too. =)
