sylvinus··on Convert curl commands to Go code
Nice! Small nitpick: "-A" doesn't seem to be supported.
sylvinus··on Show HN: Hint.css v2.0 – Pure CSS tooltip library
For those wondering, the main trick is here: https://github.com/chinchang/hint.css/blob/master/hint.css#L...

This creates a pseudo ":after" element with content set to the value of the data-hint attribute. Smart!

sylvinus··on ChakraCore GitHub repository is now open
That is probably true, but maybe this position stems more from the fact that they were never challenged than we think. I'm hoping some pride will be thrown into the mix and will make them care just a bit more than they currently do.

Competition! Now both teams have one more incentive to innovate and we get better software in the end.
sylvinus··on Replacing Redis with BoltDB – A Pure Go Key/Value Store
This is not a useful article for many reasons:

- Redis has no dependencies either

- "weird responses" from Redis? Do you change your tools the minute they don't behave the way you expect, without investigation?

- The title "Picking the right tool for the job" is the almost opposite of what's done here. It reads more like "Stumbling on cool Go software and picking what job it can do for me"

- 400 (or 850) requests/second are ridiculously low numbers for an in-memory key/value store. Redis is capable of doing 100x that on small/medium machines.

sylvinus··on YouTube change served lower-quality video to Firefox 43 for 2 weeks
I don't think it was malicious on Google's side, though it's still definitely interesting enough to be on the homepage, as it's a situation where both parties had to deal with hard technical constraints.
sylvinus··on YouTube change served lower-quality video to Firefox 43 for 2 weeks
I think the point of the parent comment is that they would have done it right away even if Chrome usage had been at the same 3.5% share.

From what he describes, it might be something like a quota service or an ad service that does consistency checks over the course of user sessions to fight spam/abuse/crawlers.

sylvinus··on Show HN: Cloudcraft – Create AWS diagrams
Great tool! How do you extend the grid?
sylvinus··on Police stop guarding embassy refuge of Julian Assange
It's pretty easy to find reasonable multiples on your assumptions. It's London and they might not be average policemen: salary x2 ; Overtime/nighttime: x2, Administrative overhead (they must spend time reporting, at the precinct, ...): x2 ; Multiple policemen (1 would not be enough to act): x3-x5 ; Management of those officers & briefings: x2-x3 ; That's already ~x100 and it's human costs only.
sylvinus··on “Alister Maclin” can break Bitcoin on command
... which makes the network less secure and thus less interesting?
sylvinus··on “Alister Maclin” can break Bitcoin on command
Can you share your thoughts on the downward pressure the miners put on the price of a bitcoin because they have to sell their rewards to pay for electricity? That seems to be compensated right now by some growth in public interest but won't the price fall instantly if growth stagnates? (In turn causing more miners to stop and the security (thus interest) of the network to fall as well?)
sylvinus··on CEO Is Not a Part-Time Job
Which is news to no one :)
sylvinus··on CEO Is Not a Part-Time Job
Twitter and Square are both individually much more successful than any company the author founded. Plus there's no actual argument in the post so IMHO this doesn't deserve to be on the frontpage.
sylvinus··on Gatsby – Static Site Generator with React and Webpack
You don't need JavaScript if the server can generate all the pages and the links are valid.
sylvinus··on How Healthcare.gov Botched $600M Worth of Contracts
You can watch a very entertaining talk from one of the Google engineers who went to fix the website at the time: https://www.youtube.com/watch?v=GLQyj-kBRdo
sylvinus··on Stripe: Open Source
Check out the footer on http://www.dotjs.io/ to be able to do that :)
sylvinus··on React, Flux, RethinkDB and SageMathCloud – Summer 2015 Update
From what you describe, shouldn't pricing be higher if users are costing you so much?
sylvinus··on Stop pushing the web forward
Was it really? I'd like to see proof that it actually helped Python 3's adoption. Wouldn't new features from 3.5 like async/await have given people more incentives to switch had they been released earlier? (they would have for me)
sylvinus··on The most underrated feature in Python 3
Sad to see this PEP dates back to 2005, and 10 years later the majority of Python developers are still on 2.x and don't benefit from it :-/
sylvinus··on Winners of the 7th Underhanded C Contest
Incredible mix of evil and genius, congrats to the winners. I'm still astounded at how many obscure ways there are in C to fool a code reviewer.

Definitely makes me feel less safe considering the amount of C code there is in tools we depend on.

sylvinus··on Andreas Gal is leaving Mozilla
I really hope Servo & other real innovations (i.e. not Firefox OS) can turn Mozilla around. The open web needs them to matter!
sylvinus··on Algolia (YC W14) raises a $18.3M Series A
Congrats to the team!
sylvinus··on Node and ARM
Smaller ARM servers are an interesting trend, see https://www.scaleway.com/
sylvinus··on Tesla Plans to Open Car Doors to All Hackers This Summer
From the title I thought they were opening an API for the car ;-)
sylvinus··on Apple Watch – What can you do with it?
Interesting that they are using a separate process on the iPhone. Is that to prepare for a future where the whole extension will actually run on the watch itself?
sylvinus··on Disque – a distributed message broker
FYI, Salvatore will do his first public presentation about Disque at dotScale on June 8: http://www.dotscale.io

It will be recorded and posted here as soon as possible ;-)

sylvinus··on Call Me Maybe: MongoDB Stale Reads
Another instance of Kyle's amazing research! You may want to catch him on stage with other great minds at dotScale on June 8: http://dotscale.io
sylvinus··on Software Updates: Courgette (2009)
I wonder how useful this could be for large-scale server-side code deploys?
