Story research filter: My imagination was sparked by a recent comment about how computer programming was considered a suitable career for women in the 1950s and 60s, akin to clerical work. I'd like to learn more about what working life might have been like for these women, and about computing in general at that time. Bonus points if you can help me name some companies in 1950s San Francisco that might have employed my character. [more inside]

The "Off The Grid" Password Generator uses printouts of Latin Squares to hash domain names into unique passwords without a PC or even a pencil.

I have a Yoga 2 Pro, freshly purchased, with an insanely high resolution screen (3800 x 1800). I generally run Xubuntu in a VM alongside windows, but I'm struggling to make it truly workable. What is the state of the art in resolution independence when it comes to Linux? What window manager should I be looking at, are there guides and tweaks etc.? [more inside]
For Christmas, I'd like to purchase digital photo frames for family members that would allow me to update the photos wirelessly. The reviews for several of the digital wi-fi frames are awful on Amazon. Do you have any recommendations for digital photo frames that specifically come with wi-fi? Or another digital photo frame that would be easy enough for non-tech-savvy people to use? Thank you.
Charles Babbage was a prominent member of the Analytical Society, and was at the very least intimately familiar with Leibniz's formulation of calculus. But did he ever read Leibniz's writings on logic? Did the Ars Combinatoria, or any of his writings on the "universal characteristic" or "calculus ratiocinator" influence Babbage's thinking about computation?

A friend and I were discussing the fact that to have a reasonable understanding of the present-day developed world, it's useful to understand concepts from computer science and engineering to have an idea of how the internet works, how machine learning works and so on.

I just purchased an underpowered computer to experiment further with remote desktops. Ideally I'd like to be able to use a remote desktop technology to stream HD video from the remote server, play a game on the client that's rendered on the more powerful server, and to have a local user work on the remote serving computer while another account on the server is being accessed remotely by the thin client.

I use a free Dropbox account for loads of stuff and I think it's a great service, but I currently only use 70% of my allowance and don't want to fork out for pro. However, I recently read the Ts and Cs of free account and see that they can delete my files whenever they like. Eek! I find it pretty unlikely this would happen, but how big a risk do you think it is? Is it worth paying just for the security, or is it so unlikely that I can continue with free service and peace of mind?
Mr. BlahLaLa and I are considering buying Kid BlahLaLa a laptop for his 10th birthday. (We want him to be able to play Minecraft and browse the internet.) We're a Mac family but I'm pretty sure this computer will have to be non-Mac because they're so much cheaper, which in turn opens up a whole world of internet security questions that I usually don't think about on my mac. Plus the whole idea of "Now I'm giving my kid a computer, what do I need to think about?" type of stuff. [more inside]

I have a friend who has become totally reliant on an e-mail account, which was provided by an internet service provider which she has just left to go to a new ISP. She uses Outlook 2003 as her e-mail client program. Unfortunately, she is now finding that after moving to this new ISP that although she can receive e-mails absolutely fine, she cannot send e-mails.

I have a pretty powerful, patented, implementation of machine learning software (genetic programming) and left my company a few months back. I have some time and have been looking at possible jobs at various companies. However, many of them seem trivial to boring, in part because I want to do something more meaningful then analyzing social media data or ad data or (ugh!) financial data. So the question is: What should I do? [more inside]
I lease a massive server that I am underutilizing. I'd like to use up to 8TB/month of transfer and 500GB of disk space to make the world a better place. I am already seeding Ubuntu distros, Project Gutenberg, and Pearl Jam shows, and I'm looking for more ideas.

I was having one of those "I walked to to school uphill both ways" discussions with friends and the question came up: What software product shipped on the largest number of floppy disks? I'm having trouble tracking it down, but I have some recollection that A/UX shipped on some insane number of diskettes, like 20 or 30, before Apple started selling it on a hard drive.

I'm to give a half an hour talk to a group of year 12 (snr high school) students as a really brief introduction to software development. Half an hour isn't a lot of time.

I am trying to co-ordinate large files (some files over 50mb) and folders with a group of people within a virtual library. People should be able to view the entire library of folders at once, and everyone should be able to upload and download the folders. It needs to be free, or very low cost.

I currently use Google Docs for cloud storage for documents I wanted to work on at home and at lunch, but I've heard good things about DropBox's usability and would like to give it a try. However, I'm concerned about my employer being able to log what I do in DropBox if it's installed on an office computer. Will my employer be able to access my DropBox the same way they can access the rest of my work machine?
I would like to know what is the best approach for measuring a cloud provider's network latency and jitter e.g. Amazon EC2. While a single ping on the command line can achieve a round trip latency snapshot for that one moment, I was looking for something more comprehensive and thorough. Are there any software tools out there that are particularly recommended and hopefully easy to use for measuring at intervals, network latency & jitter, preferably in Windows? Is round trip latency or end to end latency the best metric to consider? Ping provides roundtrip although if the packet came back the same route it came, then end to end could be found by dividing by 2. Latency and jitter increases in proportion to server load. How could I ramp up server load to let's say a specified percentage? Many thanks!
