As others have mentioned, you can find variations of this around online, but if you wish to roll you own (perhaps to add other features or what have you), you could knock it out in about 20 lines of Python using the built in CSV library and

Did you actually read the article? Here's the most relevant quote: > The reality, however, is that China has struggled to create enough white-collar jobs for its soaring population of college graduates. In mid-2013, the Chinese gove

Find an employment attorney. Pay that person for an hour or two to read the contract for you. They will be able to offer much better advice than HN.

Thank you for posting this (it was quite a surprise to see his name here). I was a close friend of Emil for a long time. Before he passed, I had gotten busy with work and hadn't spoken to him in a while. I saw some of our mutual friend

Exactly. It's so general that he's on base this time, but it's dubious if he actually has the experience to go into more detail.

Take what Jonathan Kinlay says about HFT with a grain of salt. He worked at a friend's firm briefly before leaving without making a single profitable strategy (although his excel models were profitable of course). While what he says in

Wikipedia also has a good discussion of the basics as well as some generalizations: http://en.m.wikipedia.org/wiki/Fractional_derivative Turns out there are even some applications, albeit rather esoteric ones.

I did not. I described canceling orders as no big deal. Spoofing is illegal and very much a big deal. Spoofing implies canceling but canceling does not imply spoofing. In the example I gave, the spoofer's intent is to encourage people

This is blatant misinformation. Please stop spreading it. Canceling orders is something _all_ participants do. It's a vital part of risk management and a healthy market. Some markets do have minimum quote lives, but they typically fail

Ah yes, downvotes outnumbering real responses. Classic HN.

I did miss that actually. Thank you for responding to me with something real. I'll reply again once I've had the opportunity to take a look.

That is not a valid comparison, and as someone who has been affected by drunk drivers, I take great issue with your trivialization of a serious issue. But I'd expect nothing less from HN.

I only brought that up to counter his claim that data loss is inevitable. Of course my anecdote doesn't mean it's not common =) But anecdotes are all anyone else has, and every time I've read one about someone losing data, th

TokuMX supports most of Mongo's features besides the aggregation framework last I looked. Better locking, transaction support, better indices too -- you should check it out.

This is the last one of these posts I'll ever respond to, I promise. And I'll give you the same response I've given every other time before: You should not base your decision of database (or anything else for that matter) on

Dang, I have the highest respect for what your moderation has done for HN. That said, unkilling this is just wrong. This sort of drivel is what I'd expect on Tumblr -- nit picking minor things, focusing on people's phrasing rather

I reply to these posts on HN relatively frequently these days. These sorts of accusations about Mongo are out of hand, and not congruent with reality. I say this as someone who used MongoDB extensively. I don't have time to address all

Canonical released Pollen/Polinate a while ago to address this problem. The idea is that each virtual machine queries a pool of entropy servers to seed it's own generator, and as log as at least one entropy server isn't compr

Can these kind of comments stop? Please? This has been trumpeted pretty much constantly on HN, and even if it's true, does it matter? Is anyone seriously evaluating their database on the basis of marketing copy? I suppose if you do, yo

Isn't it right there in his comment? Seems that he doesn't like the idea of having to work for free to "rank higher" if recruiters start to use these sorts of scores. Since no other profession has to work for free like t

I can see where you're coming from. For my particular apication that's not a concern (and I have sequence numbers to know when I've dropped data).

by functional_test 12y ago
I'll start by saying that I agree with almost everything you've said. I can think of one time where a loop with a sleep might be appropriate though -- if you have something, perhaps some IO channel like a log, and you want it flus

I had ~3TB before I migrated to TokuMX (same semantics, but at the time much faster indices and lower disk space requirements). It was replicated twice, although I could let reads on slaves fall behind a bit. Of course it's not good fo

I had ~3TB and it was all on hard disks (although we had quite a bit of RAM). Ultimately I switched to TokuMX which substantially reduced my disk foot print, but I was a very happy MongoDB user. My use cases may have helped (they were very

This is objectively false. I used MongoDB for >3 years with 100% production uptime and a very large data set. I get that some people have had bad experiences with Mongo. Sounds like you're one of them. Why not share your experience

by functional_test 12y ago
You may also really like TokuMX. It has the same API as Mongo (even works with Mongo drivers) but way lower disk use, faster indices, and better query semantics (e.g. updates don't affect the cursor you're iterating right now). Af

This sort of snark isn't constructive. The situation is obviously much more nuanced than this, and while this sort of reduction is cognitively convenient, it's not accurate nor useful. For example, when the money was obviously not

Overall that's great to hear, but I can't help but feel that it's too little too late. Once they fix the generics, are they going to go back and fix the secondary issues too (like the issue with Doubles)? I know this isn&#x27

Java actually doesn't have generics. It has syntactic sugar for generics, but they are so horribly broken they can't be fixed. For example, because the generics are just sugar for casts, you can't specialize them. Because you
