vdnkh··on What an attacker gets from Apple devices if they sniff Bluetooth traffic
Clickbait title: 'If Bluetooth is ON on your Apple device everyone nearby can understand current status of your device, get info about battery, device name, Wi-Fi status, buffer availability, OS version and even get your mobile phone number'

Sounds like HHS. I was there in the 00s and the borders were these "permanent" accordion wall things
vdnkh··on Facing opposition, Amazon reconsiders NY headquarters site, two officials say
That's a great source, and directly counters the "nobody else got subsidies" argument:

Subsidies for NYS:

Subsidy Total: $34,026,482,575

Number of Awards: 127,154

Earliest year of data: 1980

vdnkh··on What's New in JavaScript for 2019
From a performance standpoint it’s way better to have stdlib grow as opposed to JS bundles. Modules aren’t shared within a page so you’d end up with a lot of duplicated code that the user would have to continuously download and parse.

Please stop using gzip size for these sorts of comparisons. One, gzip affects download speed, but not JS evaluation and compilation. Two, it makes the libraries seem much smaller than they actually are.
vdnkh··on NY state tax break is $48k per Amazon HQ job
>anything to help people who already live there is what should happen.

People who live here will benefit from this. NYC has a much more diverse candidate pool than SV - 47% of our tech workers are immigrants. Our schools are more diverse; there are more programs to teach underrepresented groups CS skills. They will benefit from this.

>gentrifying forces of a thousands of tech employees.

Can you explain how gentrification will actually play out, and how it's different than 25k jobs being created organically over the next decade?

>$1.5 billion in housing

Just because Amazon has been given an incentive doesn't mean that housing gets short sticked. https://www1.nyc.gov/site/hpd/about/press-releases/2018/07/m...

> There are going to be many current NYC citizens who simply switch jobs to Amazon. Therefore they won't contribute any incremental tax increase.

How about for tech workers to get a raise? Or to move to a different part of the city? And besides, this is just conjecture. Do you have any data or polls or even anecdata which supports your claim?

Why can't they create jobs and make a difference in NYC? Plenty of underrepresented developers and future developers in NYC who will benefit from these new jobs.

Do you really believe that there isn't a tech sector in NYC aside from FAANG? Google, Facebook, and Twitter have been here for years (to name a few), along with tons of other startups.

> each NYC resident pays 48000 one time

Please cite a source which states this claim. Nobody here is forking over 48k "one-time".

1) Incentives are not given up front. They are given proportional to the results Amazon has achieved. Amazon must make a report each year detailing their progress before any award is given.

2) The city-level incentives are available to any business. State-level incentives (I think 300m) are not.

3) Amazon has pledged to invest in the local community as part of the deal. There are plans for an elementary school and tech education center.

4) The NYC tech sector is more diverse than SV. 47% of tech workers in NYC are immigrants [0]. Is there any evidence supporting the claim that Amazon will ship in majority groups to displace minorities or immigrants?

5) There is direct investment in tech education for minority groups in the city [1]. Therefore it is reasonable to assume that they will receive a chunk of these jobs in the future. If you support increased diversity in tech, it is inconsistent in your beliefs to not support 25k more tech jobs in NYC.

6) LIC built almost 2.8k rental units last year. [2] I think they have built 6k this year so far. 28k units were built city-wide last year [3]

Please tell me what about this is bad.

vdnkh··on Avoid FIFA World Cup CDN Issues
Hey, I was also at Demuxed last year! I help maintain Hls.js; it should have some form of LHLS support by soon(tm). There's no standard yet so actual adoption will be tough (current implementations use non-standard EXT-X tags to signal LHLS). But pretty much everyone does the same thing: early signaling of segments, chunked transfers, and on the client side, progressive demuxing. HTTP-based solutions typically achieve the aforementioned 3 seconds, but anyone talking about LHLS now (Akamai and Wowza) have their own protocols; it remains to be seen what the rest of us will get.

Twitch has recently implemented LHLS (looks like a "periscope-style" implementation) and I was seeing 1.2s glass-to-glass.

vdnkh··on Let’s Replace JavaScript with Something Better
JS will stick around because it is easier to write. WASM will be for heavy lifting, not for making a modal pop up.
vdnkh··on Boosting teeth’s healing ability by mobilizing stem cells in dental pulp
I had invisialign for 2 years before switching to regular braces. Metal braces can generate much more force in more directions, which was necessary for completing my treatment (very stubborn teeth). They're dead simple and reliable. But my ortho is very advanced and helped it along as much as possible - I used this pulsing mouthpiece at night called AcceleDent which helped my teeth move quicker. We also talked about an option called Propel? which essentially made small bone perforations which encourage teeth movement.

My takeaway is that teeth are very stubborn and don't like to be moved quickly. And that once moved, they really want to go back to the way they were. There is a lot of new tech, but you've gotta find the right ortho. I shopped around until I found a forward-thinking one who was willing to try new things, and got spectacular results within a reasonable timeframe.

vdnkh··on The Cost of JavaScript
I wrote this [1] guide on how to reduce the size of your JS bundles via transpiler optimizations. There's a lot you can do to write code which results in less boilerplate from your toolchain. It also covers code splitting via webpack and some other goodies (like evaulating the size of your polyfills). We've been using these techniques for a while in production (our library is very focused on size) with good success.

vdnkh··on How Firefox Got Fast Again
And they need to work better in general. I use dev edition which has a much better UI (it's pretty much Chrome) but it's much slower and has weird bugs - if you disable sourcemaps, it won't let you inspect sources, because sourcemaps is null.
vdnkh··on Ask HN: Which TypeScript codebase should I study to get better?
For better or worse? I've avoided classes in our codebase because I don't like the lack of privates via closure (revealing module pattern) and it's transpiler overhead, but it's a very powerful organization tool. I've found code to be much neater in the class format.
vdnkh··on Promise.prototype.finally
> Since async and await are strictly better, my recommendation remains to use them instead of vanilla promises

Let's not assume that polyfills are free. As far as I can tell [0], you need two Babel transforms to enable support across browsers, with the generator polyfill running you about 20kb.

vdnkh··on There Are No Houses for Amazonians
Interesting to see parts of NJ highlighted in the list. NJ used to have a huge tech sector, accommodating RCA, bell labs, AT&T, etc. but hasn't found strong footing in the software age. The old bell labs complex in holmdel (https://en.wikipedia.org/wiki/Bell_Labs_Holmdel_Complex), recently redeveloped, is undergoing a "tech renaissance" of sorts now, finding tenants such as Nvidia. At it's peak it employed over 6000 engineers on site. And it sits on a massive plot of land (complete with it's own substation, road salt facilities, wastewater treatment plant, AC plant, etc.), which is unfortunately now being developed into "luxury" homes. But maybe if Amazon started looking earlier than now when the facility was still dormant they would have found a suitable home here.
vdnkh··on Announcing Microsoft Edge for iOS and Android, Microsoft Launcher
I want to root for it but there are API differences (especially for video/text tracks) which make it hard or impossible to work with. And Microsoft hasn't yet come to the table (which Apple/Chrome/FF have been at and are very good with taking feedback from devs) to standardize on these APIs.

vdnkh··on New York City: Data Science’s Best Bet for Growth and Opportunity
I like the BoroJS family of meetups. Their schtick is "people focused" javascript. Good talks, venues, and interesting company. But sometimes it can feel a bit cliquey because the organizers are obviously good friends.

http://borojs.com/

Oops, I thought you said "meetups" not stuff outside of tech. I personally like to climb, bike, and visit breweries. Biking is fun because you can stop off and explore wherever you feel like.

vdnkh··on New York City: Data Science’s Best Bet for Growth and Opportunity
I live and work in NYC as a JS developer, and I feel like it's a great place to be. The community is strong here and there's a lot of diversity in what people do, technical or not, within the tech community. The amenities are good and I walk to work and honestly the rents are not that bad. Manhattan is the most expensive, but if you want to save money Brooklyn, Queens, NJ, etc. are cheaper and all linked by (mostly working) public transit. One of the biggest factors keeping me here is the public transit and the fact that I don't need to drive and sit in traffic.
vdnkh··on Show HN: TR-101 – A drum synth/sequencer made with Vue and the web audio API
I've tried recording WebAudio output and it's actually really hard. I think you'd have to store a representative data structure rather than the data coming from the nodes.

vdnkh··on Startup Cities Index: best cities for startup employees
Agreed. The NYC JS scene is huge, entertaining, and very nicely knit. I've visited offices and been to meetups all around Manhattan, Brooklyn, and Queens (and even Jersey). We have our own conferences (EmpireJS and EmpireNode). There are great companies here in a variety of spaces. I believe that NYC, as a city, is extremely conducive to the "startup life".
vdnkh··on Amazon Hub
I live in Manhattan and packages regularly get stolen from the hallway, behind the locked entrance doorway. Either we have thieves, or residents naively hold the door for thieves. Or bike deliverymen are thieves.
