Show HN: I built a shortcut monitoring and reminder tool
https://github.com/TomYeoman/shortcutmon
After getting fed up of always forgetting shortcuts, or to use the latest snippets I just installed in VS Code, I dediced to scratch my own itch and build a tool that allows you to -

- Track a shortcut (or key combination)
- Be reminded when you haven't used it in X time (E.G 10 minutes)
- Graph your reminders, versus usage over time to see if you're improving.

I'd love to know if there are any tools that do this already, or whether you think it's of any use to you.

Apologies the build in Windows only right now, whilst I try and resolve some compilation issues with some native modules (exaplained in the repo).
Is "Business Process Decoupling" the next major strategic trend?
http://workspaceondemand.marriott.com/
I predicted in our book, B = mc2, that one of the core strategic force driven by the Platform is the "decoupling" of business processes, for pretty much any business. This is happening.

Hotels had created value by optimizing the coupling between booking, provisioning and checkout processes. You should expect that many companies like LiquidSpace will start implementing specific processes, leaving the provisioning and/or logistics to the physical space/store/product while they handle and optimize others.

Why can we create more value that way today? Because we have the ability to integrate more tightly with the job customers are trying to accomplish. LiquidSpace, and others -say birthday party companies, ...- can do that much more efficiently than Marriott could ever do.

Ask HN: How to Systematically Turn Bitmaps into Beautiful Vector Graphics?
I've done plenty of work with web graphics, Photoshop, Illustrator, etc., but I have a problem that's trickier than anything I've dealt with before. Not only do I now know who to solve it, I don't know who to ask how to solve it.

Here's the issue...

I work for a theater nonprofit. I have a bunch of bitmap images of Broadway theater seating charts. I want to turn these seating charts into beautiful vector graphics to make interactive seating charts for our website. I could go image-by-image and try to recreate each one in Illustrator by hand, but that would take forever. I'd like to build a systematic way to take a bitmap seating chart and convert it into a vector graphic that captures the shapes of each seating section.

What's the best way to go about doing this? I realize the solution is complex and probably can't be answered on a HN post, but I'd just like to know what resources I can turn to. What folks would know about this sort of thing?

https://carmo.io/softlight/
This has kind of a weird backstory, but in short, I am doing later and later video calls and needed a way to offset the blue tint of my laptop camera, so I hacked a quick web page to use my monitor as a softlight.

Might not be suitable for all skin tones, and is a 30s hack that turned into a 15m one, so YMMV.

Expose New Linq Operations from the Screaming HashSet Collection
http://blog.domaindotnet.com/2008/09/08/the_fastest_dot_net_hash_set_collection_with_linq_extended_features/
This post will show how to gain additional power that is fully supported from Microsoft which is often overlooked, yet it can solve some of the hardest problems (especially around performance however don’t prematurely optimize!).

Linq is not just about databases. It’s about reading the registry, your hard-disk, or even a list of function pointers to be invoked. Linq is about more event then sets (collections). It’s about making tasks easier in many cases and vastly more powerful (and most importantly your code more readable and maintainable at the same time).

Review my startup: ScienceSlides.com
http://www.scienceslides.com
Unless you're a scientist, educator or a grad student who is studying to be a scientists or an educator in bio-technology and medial fields then this site might not offer too much much for you. Still, I wanted to post this here to gather feedback since it might offer inspiration with programmers with similar projects.

The website is built on Google App Engine in python. I feel that the general performance, success and maintainability of the finished product is a result of GAE's easy workflow, deployment and scalability. You really can save a whole bunch of time by not worrying about DB and hosting issues.

Of course using a big table and key-value DB vs a RDBMS has its drawbacks, we were able to work around the lack of joins, etc pretty quickly.

Overall we can see using GAE for future projects.

Cheers,

r.S.

Ask HN: Internship, a villa in Costa Rica, All paid for a month of startup work
I just launched http://www.trimpics.com and getting good traction, I am thinking of doing an internship for digital nomads, they will apply by sending a video telling about themselves and I will pick 2-3 people that I think might be a good fit.

The idea is to rent a villa down in Costa Rica with all expenses included (including the flights), and bring 2-3 people for a month of growth hacking / content marketing and motivate each other to grow the business, at the end of the month if the interns are a good fit then offer them a monthly wage to continue working on my startup from wherever they want in the world.

Ideas? Would you join?

Indian Goverment's 60$ Android Tablet.
http://www.akashtablet.com/
The much awaited India’s ultra low cost Aakash tablet is finally here and is creating ripples all around. Datawind launched Ubislate7 in India, and the student version is named as the Aakash tablet. It offers a web delivery platform that enables quality and interactive knowledge over the internet.

The CEO of DataWind, Mr. Suneet Singh Tuli says ‘This is a made-in-India product. Thank you for giving me the opportunity to do this.’ He adds, ‘The final goal is to either provide the same features at a lower cost or provide better functionality and features at the same cost.’

The team of engineers at Datawind has come up with the upgraded version of the Aakash tablet. This upgraded version of Aakash is called Ubislate 7.

Ubislate 7 will be commercially available everywhere and to everyone. This next generation of Aakash is loaded with better features and specifications, and any person can buy it.

The Telecom and Education Minister, Kapil Sibbal, said at the launch of Aakash, "The rich have access to the digital world, the poor and ordinary have been excluded. Aakash will end that digital divide."

There is definitely no other touch pad tablet or computing device anywhere near the price of Aakash tablet or Ubislate 7. It is a new generation device which comes with attractive features. This is the world’s cheapest tablet pc. This tab is made for the requirement of the users and especially for student needs.

What regular expression does Facebook use to parse the 'fields' parameter?
http://stackoverflow.com/questions/17698394/what-regular-expression-does-facebook-use-to-parse-the-fields-parameter
We are currently working on improving our REST API and we need to implement the optional 'fields' parameter for some actions. Therefore, we would like it to recognize the pattern of the request in the same manner Facebook is currently doing:

GET https://graph.facebook.com/me?fields=name,birthday,photos.limit(10).fields(id, picture)

After some google searches, we didn't find anything.
So far, we came to this (incomplete) solution:

(?<expr>(?&term)(?:[,](?&term))){0}
(?<term>(?&value)(?:[.](?&mod))){0}
(?<mod>(limit|fields)\((?&expr)\)){0}
(?<value>\w*){0}
^(?&expr)$

The semantic and syntax used is PCRE with the modifier x (PCRE_EXTENDED)

Completely different solutions are also more than welcome.

Thanks in advance.

Hey all, I'm one of the co-founders of Luminal — a new Python workspace for scientists & engineers. It's still a work in progress (it's only been a few months!), but there's one feature that I think is cool that I'd like to share already: math type for Python.

Basically it renders complex equations like this one:

e = (1-(B1.rV1*2)/μ_S(2-(B1.rV1*2)/μ_S)math.cos(γ1)*2)*(1/2)

as math type (i.e. like LaTeX), directly in your code. This can help read or "debug" equations (plus it just looks pretty).

Ask HN: Review my startup idea
I'm considering building an iPad app for creating and publishing surveys. With WuFoo's recent acquisition, I looked at innovative ways to create forms. I think an iPad app is a great platform for throwing these together, having them auto-publish to specific channels (Facebook, Twitter, etc.) without having to login on a web interface. The target would be in-between complex form builders and Facebook polling. Customers could also use it as a way to collect in person surveys with a great UX.

I always thrash my ideas and validate it with the HN community before taking the next step.
Dutch court rejects Apple appeal, says Samsung Galaxy Tab 10.1 is legal
http://www.engadget.com/2012/01/24/dutch-court-rejects-apple-appeal-says-samsung-galaxy-tab-10-1-i/
A court in the Hague has just cleared the Samsung Galaxy Tab 10.1 for sale in the Netherlands, rejecting Apple's requests for a nationwide ban. As NU.nl reports, a different Dutch court had already issued a similar ruling in October, which Cupertino promptly appealed, claiming that Sammy's slate was too similar to its own iPad 2. Today, though, the Court of the Hague shot down Apple's arguments, determining that there are enough differences between the two products to legally justify their coexistence. Granted, this is only one of many patent battles that the two companies are currently waging, but for today, at least, it looks like Samsung has come out on top.
