The Schlemiel problem is a BigO problem. BigO is really only useful analysis if your N is large enough. If you always work with data sets that are small (and have confidence that they will remain small) there is no point in doing BigO ana

Memory allocation is something that is typically O(1), or O(log(n)). The constants attached are fairly large, but doing lots of allocations/deallocations isn't a BigO issue. The schlemiel problem still exists when doing '+=' in a loop. Ea

It's possible that meetings aren't scheduled back-to-back. If there's a 15+ minute gap between meetings it's possible to end one late and still start the next one on time.

I may be entirely wrong here... but doesn't that create a tree of cons cells (more concretely a list of tuples) instead of a true hash-table? Would (gethash ...) work on the created structure in constant time?

Comer is just a straight out character. He's one of the few people who can legitimatly point at the internet and say "I made that". Yes, he knows where to point to be pointing at the internet. With that kind of work behind him it's hard to

You don't need a REPL to step through a program.

Even RAID1 doesn't guarantee this'll work. There are many ways simply disconnecting the secondary drive while cause problems: 1) The app may be in the middle of a series of DB commands that all need to complete with success before the DB i

Just yanking RAID drives isn't a way to guarantee DB consistency, especially if it's RAID5. Database backups almost universally have to be made by the database system. This is no excuse for lacking a backup system; backing up databases is

At a high level the way to defeat this kind of attack is to require more people to be involved. Large conspiracies most often fail. In this case that could mean having 3 USB disks, each with their own 'owner'. The owner of each disk would

A couple jobs ago I worked with DoD types so I know your pain... except that IE6 is shockingly recent for the military to be using ;)

Right, so the first choice is door 1, and the host reveals that door 3 is a goat. The decision to switch or not is really a decision between door 1 and door 2. At this point isn't your first guess completely irrelevant? I've heard this pro

Hmm, to avoid this being a back-and-forth between us, I attempted to find a reference for my point (which I was taught from multiple professors in college, and backed up by personal experience)... and I couldn't find any. I could find refer

I knew someone would say this ;) It is true some adults can learn language almost as easily as children, but that's the exception. The main point is that as you get older (for the vast majority of people), learning a new language becomes m

You can already pay for a premium service. It's $36/year, removes all advertisements and increases the "timeout interval" (how frequently you have to interact with it before it pauses) from 1 hour to 5. I love the service; listen to it eve

A better idea may be to not log to file. If you were to log to a database you could record things like date/time, session_id, service_name, module_name, and a generic message and do clever SELECTs on your database of events/messages and it

No real reason except that it works the way it does. It would take time to change it, and there is more pressing work to be done. That, and I don't work for the company that had/has this problem anymore.

Generally you're right. To know what will be helpful for debugging you have to know what will go wrong, and if you know what will go wrong you may as well fix it now instead of after it affects a user. Also, in any sufficiently stable sys

Yup, and here's something else to consider: You (as a citizen) are expected to know every law and can be punished if you break any of them, but you must pass the bar exam to practice law. In other words, the government holds you accountabl

This is what I was afraid of. I'm playing around with a couple toy webapps at appengine because it's free, and I'd like to do the same with ec2. I really don't want to accidentally leave it 'on' and get a bill so I''ll continue avoiding

This is something that's always confused me with Amazon's EC2 pricing. If I were to run an instance for my personal use it would, for the post part, have to be up 24/7 but it would be idle for the vast majority of that time. Would I be ch

I have very little experience with EC2 (or managing server farms). I have worked at Amazon and been responsible for an internal service there that ran on a server farm, but we didn't use EC2 and another department managed the machines. Has

We don't distinguish between them. The test programs were built and all the resulting files were checked in. Unfortunately some of the build artifacts share extensions and directories with build source, and some of the build artifacts hav

Yes, I'm familiar with rsync. We've talked with Perforce Support a fair amount regarding large files, and they remind us that we are abusing their system. It's like using Harley Davidsons on a worksite to move around loads of dirt. It ma

Perforce is not terrible. I'd even go so far as to say; of the centralized systems, it's better than any other I've tried (including Subversion, and cvs). It could be better, but it could be much worse. Things we like about perforce:
