jermy··on A Python Guide for the Ages
The way you describe is how it worked in zope templates (allowing a 'no items here' text if there was nothing to iterate over in a list) - it was frustrating that the later python implementation was different.
jermy··on When I Took My Zipcar Into the Wilderness
They plug in to a socket in the glove compartment, and I don't think the rental is counted as completed until they are returned there. I'd naively assumed this was standard across the globe, but clearly there must be other factors to warrant not allowing you to remove the key.

On the other hand, the fuel payment card does missing - but at least Zipcar in the UK are efficient at refunding your own payment when provided with a receipt.

jermy··on How to Find Hidden Cameras in Your Airbnb
I think it might have been a pun relating to the phrase "Going Dutch"
jermy··on Alan Turing to feature on new £50 note
On a point of technicality - he was only two years old when the Great War started! (I think you meant the 2nd World War)
jermy··on Intermediate Vim
Just to extend this - if you're often using different users (or need to otherwise deploy via a configuration manager), I've found out that a good way of having system-wide options on Debian is /etc/vim/vimrc.local with something like:

   " Workaround stupid defaults.vim behaviour
   if filereadable("/usr/share/vim/vim80/defaults.vim")
      source /usr/share/vim/vim80/defaults.vim
   endif
   let g:skip_defaults_vim = 1
 
   " Disable stupid seeking to last position
   autocmd! vimStartup BufRead
 
   " Disable stupid mouse support
   set mouse=
jermy··on Intermediate Vim
Likewise - with visual mode it's normally pretty quick to select an area and do a basic regex, even for things like re-indentation (auto-completes to something like :'<,'>s/^/\t/) even though I'm sure there's a 'proper' way to do that
jermy··on Why does APT not use HTTPS?
We deploy our software packages to our own infrastructure and clients using a private APT repository and basic HTTP auth. Obviously we're running it with apt-transport-https installed for making the latter not completely insecure.

I see no reason to do that for signed packages from the main repositories, however.

jermy··on Bloomberg’s ‘The Big Hack’
Unless we use Supermicro kit, presumably?
jermy··on Flipped Iceberg (2014)
Jökulsárlón lagoon in southern Iceland is a fascinating place for this - large blocks of ice break from the glacier at the top end and slowly float towards the outlet of the lagoon to the sea.

Near the outlet the iceburgs catch on the bed of the lagoon and tumble as they melt. There's a glorious variety of colours as the ice as the freshly exposed dark glacier ice is exposed - like in the attached article - before the ice surface melts and it returns to a white colour.

jermy··on Google Coder Analyzes a Billion Files to Find a Winner in Tabs vs. Spaces Debate
We had people in the same team with the same differing opinions 15 years - we compromised on a coding standard of 3 spaces, and anything else looks wrong to me now.
jermy··on Cheap HDMI capture for Linux
I'm not who you responded to, but the DeckLink Mini Recorder (towards the bottom of https://www.blackmagicdesign.com/products/decklink/models) is a very capable PCI-e HDMI and SDI capture card for around £100/$140.

Apart from possibly needing an update to the kernel package, all of the DeckLink devices are supported by the same SDK, with only some small variations (like giving the user the choice of selecting which input connector to use or similar).

jermy··on Future Screens Are Mostly Blue
And a typical aircraft flight management system would involve inserting a series of instructions then pressing the execute button.
jermy··on The Future Google Rackspace Power9 System
Is this possible? Fault currents are much more obvious at a higher voltage than lower, and I thought most RCDs would not be made to be sensitive enough to catch what might be a dangerous DC leakage.
jermy··on Why Did Ancient Europeans Just Disappear 14,500 Years Ago?
A friend wrote a blog post at http://www.huffingtonpost.co.uk/hannah-griffiths/isis-climat... whilst in Iraq, which refers to the Columbia University paper at http://www.pnas.org/content/112/11/3241.full

It's very much a picture of the drought causing people to move to overstretched towns and cities to look for work, and rising discontent with their government as a result. In some areas, mercenary work might be the only paid work available.

jermy··on Optimizing Python – A Case Study
You should probably first consider seeing if there are critical bits of code that can be rewritten to use MMX/SSE instructions, since your data is in the right cache already, without needing to move it anywhere else.
jermy··on The MS-DOS Showcase
Windows NT 3.1 (1993) and its successors (NT 4.0, Windows 2000, XP and the server equivalents) was independent of DOS, but was separate to the other OSes (Windows 3.1, 3.11, 95, 98, ME) that ran with a hybrid 16-bit/32-bit monolithic kernel on top of some sort of MS-DOS.

jermy··on BBC announces the closure of the Digital Media Initiative
There's a bit more info from somebody on the inside over at http://www.reddit.com/r/unitedkingdom/comments/1eyrdo/bbc_ab...
jermy··on BBC announces the closure of the Digital Media Initiative
It's very unlikely to be useful, unless you are running the same platform and have an interest in implementing business rules for the same use cases as the BBC have. Much of the interesting functionality will have been licenced from outside providers, and most of the cost will have been paying Siemens, paying Siemens to cancel the contract, and other staff and consultant fees.
jermy··on BBC announces the closure of the Digital Media Initiative
The irony is that we (the company I work for) already do low-resolution web-based proxy editing. The BBC has know about us since 2006 - we were even part of the original DMI tender process, but have been sidelined through all of that, with preferred vendors and consultants taking over (actually, we were also part of two of the six large-consultancy bids on the second round, but that tender was again dropped when Siemens were idiotically awarded the contract instead).

You're absolutely right about proxy content not being right for all markets - especially Drama - but it's not just a question of getting a good enough quality encode. If you don't have a calibrated display on your BBC desktop, then it's pretty meaningless. We are used as a production tool for logging and rough-cut editing on high shooting ratio (typically reality) programmes before an offline edit, and will save a lot of hours in editing suite time.

The DMI has been in the way of us being able to sell to the BBC for many years now, even though it has been a ghost ship for most of the last year. We were unsurprisingly delighted (as a company, of course, not as licence payers) that it has been officially dropped today.

jermy··on Panoramic, high resolution picture of London
It's on a Sunday, and central London is always genuinely quiet. If you want to find lots of people, look at more touristy places like the Southbank http://btlondon2012.co.uk/pano.html?view.hlookat=-33.2466...
jermy··on Panoramic, high resolution picture of London
Since I've had nothing better to do that look at the pictures for a bit, I'm confident that it was Sunday, 28th October 2012, with one set of photos starting around 1pm facing north and another one used for filling in gaps a bit later - starting somewhere between 3pm and 4pm (harder to be precise - there are fewer clocks visible from this one).
jermy··on RSA splits passwords in two to foil hacker attacks
Video at http://blogs.rsa.com/idp-beat/announcing-rsa-distributed-cre...

Any suggestions of what might be worth $150,000 in all of this?

At a basic end, this seems to be similar to storing every other character of a suitable hash on two nodes (preferably running heterogeneous architectures). RSA's ability to 're-randomise' suggests the ability for the two machines to be able produce a plaintext version of the password, which obviously seems particularly dangerous, especially if somebody is sloppy and backs up both nodes to the same location.

Is there any distributed encryption algorithm that could be done that would allow straightforward credential verification as well as the ability to re-salt a hash securely without knowing the plaintext?
