I think that would depend on the data type and sizes. A single row in a PG table cannot take up more than page size (8kB). If you have a 100kB TEXT field the row will instead contain a reference to an "overflow" table rather than the data i

Note that Gmail automatically saves your draft as you type it. So while this will offer some protection for the message while it's in transit from Google's server to your destination, your unencrypted message draft will still be sent to Goo

I wonder how well the SMART stats would predict that failure -- or whether they were sudden unexplained failures. If you run smartctl -A on your SDD device then for e.g. Intel you can see attribute 0xE9 or 233 -- media wear indicator, start

Does this use SNI ( http://en.wikipedia.org/wiki/Server_Name_Indication ) to allow for multiple vhosts on same IP? (since they use a *.showoff.io wildcard certificate). As I understand it, SNI does not work on IE7 on XP (Konqueror apparen

Can anyone comment on omitting Content-Length in the response, versus using chunked encoding? Will chunked encoding simply give you more control over when the browser executes the content, or perhaps be more compatible with any proxies in b

In a macabre follow up to the crash, the (Danish) ATC on duty was murdered by a Russian man who had lost his wife and children in the crash. 3 years later the man returned free to Russia, was hailed as a hero and given the position of a dep

Mixed reviews on the Google Apps marketplace for backupify: https://www.google.com/enterprise/marketplace/viewReviews?pr... -- 27 users take 21 days to backup? Might well be the Google Apps infrastructure that's not up to the task. Lookin

I've seen it used for a long time. The only problem with it is the quadratic time complexity: it's equivalent to ((N0 + N1) + N2) + N3 ... so you copy the same elements over and over again as the sum builtin doesn't know to use anything bu

What's wrong with copying zlib around to every project? Well, have you forgotten the 2002 zlib vulnerability where 100s of copies of zlib source had to be fixed up? I believe there were half a dozen of separate copies of zlib source code in

Unfortunately as an administrator (outside of a soft policy) there doesn't seem much I can do to ensure that my users have an encrypted ssh private key nor can I control what other machine it's copied to. Which is something that worrying w

I used gdb plenty in C/C++ but that was mostly to debug mysterious errors when exceeding array bounds. Back then continously running server software that crashed would essentially move away its core file and restart, then just run gdb on it

YMMV but for my Python web app executing mostly OO Python 2.5.x code, I got a 10% performance increase by using jemalloc compared to the malloc in RHEL 5. It's as simply as LD_PRELOAD=/path/to/libjemalloc.so -- memory usage is also better (

Hans Reiser was, by any account, pretty smart. His journaling filesystem was quite a technological leap over ext2 at the time. Yet he did murder his wife. Some hardcore fans denied his guilt up (some claiming his mild autism was exploited b

The double quote quoting, while allowing you to do e.g. rm "file with spaces" still expands $ and `. Compare: echo none:`date` echo double: "`date`" echo single: '`date`'

I've written 2-3 kLOC of both boost::python and Pyrex (what Cython is based on) over many years to greatly speed up critical parts of my code, and I'm sticking with the Cython way from now on. Boost::Python uses complex template meta progra

There are three options that I know of: 1) SNI -- this has just too poor support at this time 2) Separate ports -- you can make make Apache listen on for example port 446 and use links like https://subdomain.foobar.com:446/... . -- however

The result of this is a 64-bit double (there are no other numeric data types in JS and this is the data type regardless of the underlying CPU architecture). That has just under 16 digits of precision so the above code will not lose much by

TCC has two even more cool things: 1) a library that lets you compile C code within a process, relocate it and execute it. This is rather faster than shelling out to run gcc to create a shared object and open it using dlopen. 2) an awesome
