...l access of data. When you see a request in REST, it should immediately be apparant what is happening with the data.
For example:
GET: /cars/make/chevrolet
is likely going to return a list of chevy cars. A good REST api might even incorporate some output options in the querystring like ?output=j...
Convert PDF to clean SVG? [closed]
...hs, too. I also find that they often lose the font data, but don't seem to approximate a good, installed font. How does PDF display it if SVG can't?

Wait for all promises to resolve

Django - what is the difference between render(), render_to_response() and direct_to_template()?
...late[, dictionary][, context_instance][, content_type][, status][, current_app])
render() is a brand spanking new shortcut for render_to_response in 1.3 that will automatically use RequestContext that I will most definitely be using from now on.
2020 EDIT: It should be noted that render_to_resp...
Why is there no xrange function in Python3?
...ments, using timeit instead of trying to do it manually with time.
First, Apple 2.7.2 64-bit:
In [37]: %timeit collections.deque((x for x in xrange(10000000) if x%4 == 0), maxlen=0)
1 loops, best of 3: 1.05 s per loop
Now, python.org 3.3.0 64-bit:

Why use Ruby instead of Smalltalk? [closed]
...to facilitate integration. Smalltalk never really gained a body of hybrid application support in the way that Python and Ruby have, so the concept of 'smalltalk as embedded scripting language' never caught on.As an aside, Java was not the easiest thing to interface with other code bases (JNI is fai...

Practical use of `stackalloc` keyword

Small Haskell program compiled with GHC into huge binary
...braries are copied in verbatim.
Aside: since this is a graphics-intensive app, I'd definitely compile with ghc -O2
There's two things you can do.
Stripping symbols
An easy solution: strip the binary:
$ strip A
$ du -hs A
5.8M A
Strip discards symbols from the object file. They are generall...
What is the difference between Non-Repeatable Read and Phantom Read?
...solation level to be used?
What isolation level you need depends on your application. There is a high cost to a "better" isolation level (such as reduced concurrency).
In your example, you won't have a phantom read, because you select only from a single row (identified by primary key). You can ha...
