Seems me and pandodaily have a different definition of "engineer" Hear, hear. That comparison was insulting. That's like calling a child playing cowboy with a plastic gun a member of the SAS; it really puts down all the har

We might just as well claim that Javascript is Perl then. Javascript has a lot more in common with Perl than it does Scheme; those things that both Javascript and Scheme have in common are also common in many other languages. Anyone trying

The newest version of Opera strips away most of the tools power users like. It's one step away from Chrome's UI. They'll probably add most of it back, but it'll take a long time.

They're also simpler and better understood than most modern computers, minus some embedded systems. Complex and new are enemies of reliable.

If it has LZ4, I don't think it has a zpool version. Versions were deprecated, and now ZFS uses feature flags instead.

A problem with persistent data structures is that they're memory-hungry. Combining that with the overhead of a garbage collector... I think such structures are useful (and nice!) in some circumstances, but as a general solution for efficien

I'm not sure I agree with the point regarding concurrent data structures and garbage collectors. The idea is nice, but ignores a rather serious problem in implementation: such garbage collectors are serious engineering undertakings. To se

Currently 1.2.11. As you can see above, I've only ever installed one package globally (jsontool).

That's odd. I've worked with node for a couple years. I've used npm hundreds of times, and I can count on one hand the number of times I've used it in combination with sudo (and all but one were a mistake). ~/dev $ ls /usr/local/lib/no

These people number in the tens, if not hundreds of millions, so clearly there's a market for it. It'd be like a Cintiq, but actually affordable. That, and you can move and rotate an iPad around almost like a sheet of paper while drawing.

This is the most depressing comment I've read all week, for so many reasons. :(

Another fine example were the Mongols. They achieved a lot with very few soldiers. They also left mountains of skulls (literally) and cities where they murdered everything (including animals) in their wake. Suffice to say, after a while n

Mayhap you refer to Crenshaw's tutorials.

How are threads handled? The standard Unreal engine isn't single-threaded.

Yes, but I think what ksec was driving at is there isn't an intrinsic reason what you said should be true. Why should Ruby (and scripting languages) be used for RAD and not performance? That's because implementations range from really slo

My experience with SANs is that they are anything but consistent. Local storage is a better idea: fewer moving pieces to go wrong, fewer moving pieces to understand and debug, fewer possible sources of contention, and the latency is low. SA

I'd suggest that for most of my cases that are not source code that I'll stick with ack.

by dmpk2k 14y ago
There is a large world beyond source code. Surely you've done some system administration or looked in logs?

How about memory usage? For what I do, that's considerably more important than CPU.

Unrelated to the topic at hand, but I've been happy with SmartOS. It's firmly and solely an OSS server OS, it's easy to use, many of the uglier Solaris legacy bits have been sanded off, and it has a decent package system (pkgsrc). My earlie

Did you use zpool import -F (are you sure)? I'm surprised that'd be necessary though, given my experiences. How long ago was this?

While I concur with most of your points, I must point out that there are four uberblocks, not one; a flipped bit will not impair the pool. Let's argue that bits flip in all four uberblocks though, then ZFS will use the previous valid commit

As I've asked elsewhere in this thread: given the way ZFS works, you'll have to elaborate on what an fsck would do that ZFS doesn't automatically do already. I'm getting "we need an fsck that does magic " vibes here.

by dmpk2k 14y ago
Of course there's problems with the disks -- corrupt sectors, phantom writes, misdirected reads, etc. The point is that ZFS handles those problems for us. I won't discuss the nature of the business, but it's unlikely that actual corruption

Given the way ZFS works, you'll have to elaborate on what an fsck would do that ZFS doesn't automatically do already. What I find scary is silently corrupt data, something which is a problem for most other filesystems. I've seen ZFS catch a

by dmpk2k 14y ago
But how much checking does it do to the ZFS structures themselves? They're validated as well. Everything has a cryptographic checksum that's stored in the parent block, starting at the data and working all the way up to the top of the tre

Disk lie. A lot . Ask anybody who has the misfortune to work on a filesystem for any length of time. One thing to keep in mind is that ZFS is more complex than your typical filesystem, but it's also one of the few filesystems that's effect

My employer has thousands of large machines with ZFS on them. We've seen corruption happen once, five years ago. Maybe we've just been really lucky.

we've been jerked around for a few years Oracle's ZFS (and Solaris) fork is a deadish end. Most of the interesting action the past couple years has been happening among a collection of illumos (including critical ZFS members formerly from
