This is just a bit too awesome, yet simple. Think of it as the "git" for debugging. Take a snapshot, keep going etc ... and then backtrack back to the point where it all started going wrong. Just very hard to automate easily, yet

For several years, you were considered to be living in the stone age if you still wrote PHP code. I think that trend has ended somewhat now. PHP is no longer uncool, but something useful you can use to throw your web-fronts together. Altern

Why Macbooks? Is Apple friendly towards people who replicate their connector interfaces? Or are Macs the only popular device out there where people wish "I wish I could carry an extra battery!"?

PHP is fast - I've been there, made ~4k RPS websites in PHP & memcache. There's one big, primary reason for it. PHP is dumb. You can't do clever things in PHP with the language, you have to all the clever things in how yo

It's about the false sense of security. And that betrayed sense, which invokes a hint of paranoia - that bug looks too obvious to have been skipped in QA.

Ugh, is this going to look like Big Tobacco in 50 years? Vice taxes and revenue streams to be kept alive for the district? That's going to be such a kick-in-the-backside for everyone who just wanted to decriminalize it & stop putti

Python actually comes static shapes for objects with __slots__ class vertex(object): __slots__ = ["x", "y", "z"] I use __slots__ in most code after the first refactor for a very important reason - I&#x2

I have never used a setup like that - all I've done is throw an SSD in front of 3 disks. That said, the zfs log and zfs cache command supports mirror disks for log and allows more than 1 cache per pool. Using more than 1 SSD as a cache

They are both check-summed and copy-on-write. This is great for consistency and storage, but the first part somewhat sucks if you've built it into your layer as well (like hadoop fs). And it makes writes & reads a tiny bit slower t

I like Julia, but their multi-machine stuff needs a jolt. I spent some time with HDFS.jl and trying to re-do spawn to launch tasks onto a HADOOP/YARN cluster, but couldn't really get @everywhere includes to work. But oherwise comp

"perf top -e syscalls: statfs " particularly when you don't know which process is calling all the syscalls. Mix "perf record" and "perf trace" & you have the next generation of strace tools.

Carry a notebook, if you actually sit down in the train. You'll find that you are far more insightful and lucid when excluded from wasting time online/starting at a screen. Doodle, write, note down each station - just treat every

Rasmus wouldn't be idealistic (say compared to RMS). I have been in contact with both over different parts of my career. Rasmus is pragmatic. In some sense he would say "sure, go ahead and write that code" without telling you

The best teams I've worked in has had A-players, B-players and C-players. Some of the C-players were wild kids with potential, who needed mentoring. Some of the B-players were people who were not motivated at all - some because they wa

I feel for this guy - people can't understand that what he wants is "Life his way" and not to be a martyr to society burning his happiness to solve up equations. The greater good and so forth. But there is a fundamental angle

I fully understand what this means and I hope you do get calls about alternate licensing, but remember that people like me do not make these decisions. I thankfully don't have to - this means I don't need to talk to lawyers about

GNU AFPL? Clause 13 is a real pain to deal with when exposing this over the network. I guess the developer wants to sell a license (like the mysql java client GPL'ing). Can't blame him, he needs to get paid.

Sometimes it is a question of self respect. It's perhaps the last thing people cling to, to keep their sense of self alive. It is what probably keeps him going now. My father refused to take any real help, till his final days. In his o

That is just step #1. Waiting for quality for release is always a mistake. Release, refine and re-release. And A/B test, run the funnels and measure change as it happens. Productivity on day #1 with bad code is a technical debt you tak
