hvm··on Kore: a fast web server for writing web apps in C
I think the idea still stands. PHP is a fake high level language in my opinion.

A high level language should reduce boilerplate and 'force' you to write concise and predictable code.

PHP does none of that especially in the context of error/exception handling.

hvm··on 8^8 – Find another you
Well to be honest after many attempts to try it out I started to get a bit frustrated and annoyed.

From the errors returned I'm pretty sure it's a PHP backend. Considering the expertise of the average PHP developer I don't think I need to say more (this might sound mean but it's not).

Yeah, the site is painfully slow. A site with a multiple choice test should handle thousands of users at a time with a tiny server. How is this thing made?

OK, there are no errors now but I still get the error. Does it use some other port? Do I need to open one?

OK. I see it opens a websocket which I guess I need to also forward to my server.

There is no mention of bower install in the install doc. I'll try that

I followed the installation doc, everything seems fine and the server starts (node bin/curvytron.js).

When I access the server I get an error page. I looked at the browser log and it shows 404 for /js/dependencies.js.

I thought it was because I set it up behind apache but wget localhost:curvy_port/js/dependencies.js also yields 404.

I don't exactly know how to contact the team about this since I can't say it's a bug so I thought opening a github issue about it would be bad form.

I installed it but I get 404 on /js/dependencies.js. I'm not experienced with node.js and the like, what can I do?
hvm··on Death for stealing candles
Also, like I said in a previous comment, it's interesting to note the 'interview' given to the condemned: http://www.oldbaileyonline.org/browse.jsp?div=OA17160127

I also wonder what's up with those two names in the 'burnt in hand' section that are anonymized (V--- E--- and G--- C---). Public people not wanting others to know about it? Escapees? People with no public records?

I love this kind of historical information. It's difficult (to me) to empathise with past historical events when we (I) have no knowledge of those people and how they lived.

Reading about their daily struggles gives events from that time a whole new image.

BTW, I found extremely interesting that they gave the condemned an interview which they then wrote down ( http://www.oldbaileyonline.org/browse.jsp?div=OA17160127 ).

How many average people from that time have the luxury of their lives being recorded for future people to see? How many of us have that today?

hvm··on Show HN: I'm a 14 year-old dev who has programmed an artificial intelligence bot
It's programmed after a 14 year old - asking the same question until he gets an answer and then asking it some more :D
hvm··on FacePay?
How do you have better data than Facebook on how many users use the Messenger functionality and how many use all the others (feed, etc.)?

And having the same functionality in two apps is not a good idea in any scenario.

hvm··on Dropbox accesses all the files in your PC?
He has a tool that checks for accesses on specific kinds of files and he uses that and a few specially crafted files to see what happens. That tool might even influence other processes for all we know.

How does a security researcher not know about procmon? another user here did a test and found no problems.

Try Bittorrent sync, it matches all your conditions
hvm··on Dropbox accesses all the files in your PC?
Have you heard/tried Bittorrent sync? It's P2P, doesn't put your files on their server. Very fast for transferring locally between your phone and computer for example. You have to keep your computer running if you want your files accesible anytime though.

hvm··on How Do You Get a Train Moving?
Also, this is why doing a wheelspin is never a good idea when you have trouble starting your car/train. The traction when the wheels are blocked but the engine tries to move them is always a lot better than when they're spinning in place.
hvm··on How Do You Get a Train Moving?
The article has the physics completely wrong.

Static friction is what opposes movement between two surfaces that are static next to each other and kinetic friction is what slows down movement between two surfaces. Static friction is always >= kinetic friction.

This is explained very well in here (the top picture says it all): http://hyperphysics.phy-astr.gsu.edu/hbase/frict2.html

Think about how when you start your car from a standstill you need to be careful about your clutch release but when the car moves even the tiniest bit you can even start in the second gear if you want.

So, the engine car's wheels get kinetic friction (because they're rolling) and the other cars' wheels (which are stopped) are blocked by static friction. When you have slack and you move one car at a time you only need to beat the static friction of one car at a time. Even if the difference is 10%, if you have 10 cars and it starts to add up. I'm not saying slack is required for starting the train, just that there is an increased difficulty in doing so without slack.
