When I say limiting trades, I mean naively saying 'I will have at most x positions outstanding'. Each trade has an associated risk (variance), that interacts in complicated ways in a portfolio, which I'm sure you know. silly example, 100 sm

Being pedantic, 4000 trades a day isn't HFT. This is stil algo trading, of which HFT is a subset. I consider HFT to be any strategy where speed itself is the what gives the edge. Colocation is usually a prerequisite, though not sufficient.

555 was the first IC I played at school when I was 12. Was always amazed with how many things you could do with it.

Anyway to make mutt(or any cmd mail reader) use the Mail.app database, stored in ~/Library/Mail? I already have Mail.app configured, and it has downloaded all my gmails accounts into the plain text emlx format? Also have 10gb+ of mail, and

completely agree. I've only written toy haskell programs, BUT it has heavily influences all my other code (js, c[++], java, ruby).

When I was at student at Imperial College, London, programming 1 was all taught in Haskell http://www.doc.ic.ac.uk/teaching/coursedetails/120.1 It seemed like a silly idea then, but in hindsight was a genius move. It normalised the class

As our ads are affiliate links (CPA), it shouldn't be a problem as a user has to actually buy something for payments to go through.

The point wasn't that creating on the fly zips is new, it was that using pipeable steam abstractions is a composable way to build network servers, and nodejs is just something we found this easiest to express with. Having a large number of

The full size origs are only stored on the server, the client just uses thumbnails so not much point in zipping on the client

pipelining data isn't new (Unix pipes!), but it's an very elegant architecture for IO heavy servers, and highly underused because of (perceived) implementation complexity. Many devs don't realise they can create streaming pipelines, and end

We use it to mean, the quick and dirty simple solution that we write first, and that is usually good enough but your a little embarrassed to admit. It's not the elegant or crafted, but works. Our original solution was literally a shell exec

I think you have pretty much described our original ('ghetto') solution with caching ('lipstick'). With streams, there is no need to cache, as recreating the download is dirt cheap. Essentially just a few extra header bytes to pad the zip c

by dmmalam 15y ago
Ye, 100% true. I've spent many man-years writing entire systems like this in C and Java. It's just in node, doing it in the evented way was actually simpler and quicker to implement, than the 'ghetto' way. This isn't usually the case, and I

Nice catch, We are working on it! dumply knows the exact size of each image as it is saved in the DB on upload, and all the zip byte headers are fixed, so the zip file size should be deterministic and calculable even before the first byte i

Any chance of del taking a pattern happening in this or the next release?

Totally agree. I've done exactly the same with the excellent node_redis driver. A thin layer to remove boilerplate, but still directly fire commands at the DB.

Is it possible to use a script to roll back redis transactions. Currently transactions aren't like SQL transactions in that they don't roll back if there is a problem executing the commands between the multi/exec. Say if I add a new hash, a
