Everyone seems to be obsessed with paying more into the education system. Chicago Public Schools have an average teachers salary of around $75,000. This in a city where the average household income is around $43,000. Clearly the money is there and teaching in Chicago isn't some poverty inducing measure.

The outcomes are fairly poor. For students that bother with the ACT the average score is 18, but for Illinois as a whole its 21. 18 is a score that only gets you into the most poorly ranked of colleges. CPS teachers also average 18-19 on the ACT as well. Graduation rate floats are 50% and the powerful Chicago teachers union fights against any performance testing of teachers impossible to implement.

The reality is that we absolutely don't need more education or more education dollars. We need higher quality education. Public sector unions have made sure to make this all about tax dollars, when it should be about teacher performance and student outcomes. This means teachers taking responsibility and administrators firing poor performing teachers. It means a lot of politically difficult things, thus why it doesn't really happen and why anyone with means in Chicago goes to private or charter schools. Or more commonly, white collar professionals move to the suburbs when they have children.

Also the mayor just wrote a op-ed piece against vouchers for private schools. What public school do his kids go to? None. They go to private school in Chicago.

Snapchat is not a Facebook property. Nor do I think Apple has resources allocated to review a library used by any app to facilitate if queries on the ntppool are kosher.
New GPU and killer wireless instead of Intel.
Honestly, I think a docking situation like that looks awesome. I like the idea of just usb-c, but Apple was probably a bit ahead of the curve here. In a year no one will be talking about it, and places like monoprice will have cheap dongles.

I also get what Apple is trying to do. My current MBP has the sd-card reader. I use it because I have a d7100, but everyone else I know with a mbp has literally never used that reader. For them it's a complete waste of space/weight. It is easy to get caught up in what we (as in HNers) need, and miss the fact that many people probably never using anything beyond the power port.

It's a similar situation with the removal of the headphone jack. Apple has stats and those show that the majority of people either use the headphones that come with the phone or have bought BT ones. Apple got ripped hard, but the rumors are most of the flagships coming out next year will also not have a headphone jack.

I think it's pretty safe to assume that the developers have no idea that things like vendor zones exists. NTP, like DNS or SMTP, is ubiquitous infrastructure, not something the average developer sets aside time to understand.
I think what he/she meant is that higher education has become the new high school. What we need is a restoration of secondary school education, not "universal college degrees."

That, and we need to re-value our currency in the same fashion.

Following that argument then simple-minded businessmen or people with a Manichean world-view should be great at taking care of babies, since they make quick judgement calls?

Sure, but the amount of oil needed for that is completely dwarfed by other uses of oil. See e.g.

Apple have something like a 10% market share. I think what you see in coffee shops and on expensive commuter trains is not at all representative; if you go into a Starbucks in a trendy part of east London, you'd be forgiven for thinking that Apple had a 95% market share, but I'm pretty sure if you go to, say, eastern Europe you'll see very, very few Macs.

The only reason why I regret buying a Thinkpad is that I see good machines like the XPS, but I'm not willing to buy them because I have been spoiled by Thinkpad's keyboards.
I don't buy this. XMPP uses no more than any other IM system, and much less than most. The military use it over HF links in theatre, for heaven's sake - this is not what you'd choose to be doing if the bandwidth was so high. (HF is STANAG 5066, and runs down to a handful of bits a second - this stuff is not fast).
the XPS 13 runs linux perfectly.
Apple's trackpad drivers for Windows are some of the worst on the market. They just don't care.
This really isn't the sort of thing that would show up on an App Store review. The tests aren't done by engineers, so something's only going to get caught if it's noticeable by the user or gets caught by automated tools. (e.g. use of private APIs.)

Excessive NTP queries aren't going to cause noticeable issues on the device or on Apple's test network, especially with only one or two people testing simultaneously.
I switched from Firebug to DevTools one and a half years ago and - while I have huge respect to the innovations that came from Firebug's ideas - I'm not looking back as the native devtools have more features these days and a better UI in my option.

So thanks to the dev team and the volunteers picking up my and others bug reports at http://firefox-dev.tools/ (I just leave this to the crowd here on HN ;)
> Hopefully they were just unaware of the vendor zone policy.

It seems they didn't know, or didn't care, how both the third party iOS library they used and the NTP worked, see my other posts here.

They surely didn't need ntp.org pool at all.
Is anything Facebook currently doing not shady?

I'm not even trying to be snarky, it just seems like every single thing Facebook is doing lately is tainted with misinformation, corruption and spin. Just endless spin and lies.
It seems like they block access to the US store from outside the US? No VPN here, just a DE IP and it's blocked.

Interesting article.

I haven't internalized all the parameters of the Go GC, but I wonder if there's a way to tune it on the fly. For example, if I want to run at 60 FPS (16ms/frame), and I've measured that actually doing all the CPU side work took 10ms, can I let the GC have ~5ms of GC time (rather than the <1ms advertised) at the end of my frame to increase throughput (read: less cycles burned overtime & better power efficiency)?

If not in Go, can I do this elsewhere like on the JVM?

Hopefully this isn't too off topic (since the article is about trade-offs of throughput vs latency).
Most likely it was doing something naughty in it's network stack.
Exactly - as long as the unit economics (revenue per unit is more than the variable cost to create and sell it) are positive, software companies can grow past their fixed costs. One SaaS companies grow past their fixed costs, they are machines for throwing out cash. People who are too short sighted to see this are better off investing in public equities rather than early ventures. If unit economics don't make sense, then the founders and early investors deserve to lose their money.
Sure it is. https://xmpp.org/extensions/xep-0365.html
They didn't have to use ntp.org pool at all. They obviously wanted to check if somebody changed the time on the phone and to still use "the internet time." And for that contacting one Apple's server (time.apple.com) were enough.

It seems that the iOS library author "helpfully" provided the default of contacting 30 servers from the ntp.org pool.
> Backprop knowledge, however, is much more crucial to design novel deep learning systems.

I would argue that it's not just for that. You need to understand what is happening inside DNN if you want to construct it properly.
That's an odd view of Sustainable with Oil being a finite supply. Further, cost-effective assumes cheap oil with massive economies of scale and 10's of billions in R&D vs small scale trials of new tech.
The current gen (9550) graphics run in NVidia Optimus. There is no way to change to Only Integrated or Only Dedicated graphics in the BIOS. This means that you depend on the NVidia driver to switch to the graphics card based off which application you are running in Windows.

It's a big pain in the ass for linux. You have to fool around with nouveau or Bumblebee to get Optimus working. Even then I was never sure the graphics card was doing anything in Linux.

I wish all manufacturers would put a hardware mux on the graphics so that it could be switched from Optimus to Only Integrated or Only Dedicated. It seems to be going the other way where they don't and only offer Optimus though.
In my experience a few years ago, Dells are much easier to open up and work on than most other laptops. If you are the sort of person to build your own desktop PC you might consider doing your own laptop repair rather than deal with warranty support.

Based on the title I was expecting a tribute, thanking Firebug for paving the way, so to speak, for the modern DevTools. But this is even better! I know a lot of people preferred Firebug, so hopefully the marriage of it and DevTools will mean good things for them.

In my day job we're using an Infineon SoC with an ARM core. Because it's mixed-signal with 20-30v power stuff on a 130nm process, the ARM core only runs at 40MHz. See here: http://www.infineon.com/cms/en/applications/automotive/body-...

The SiFive RISC-V core runs at 320MHz on a 180nm process IIRC, so I'm wondering if a near drop-in replacement would get me better performance on the SoC I'm using. It certainly wouldn't hurt and they could save an ARM license fee. As a customer I'd switch in a heartbeat if I could get faster throughput.

Now there are other companies that make gate drivers and the other peripherals we need but don't have a CPU core. They could readily compete with this chip by paying SiFive or one the other consulting companies to help them integrate a RISC-V core with their existing IP. No per-unit costs, and the software toolchain is already there. Anyone can use it to ease the transition from analog to mixed-signal.

The X1 Carbon (latest.. 4th? gen) is my daily laptop since release and I can't wait to get rid of it. In anything other than low light/perfect lighting the screen is unbearably dull, speakers are appalling (though in ubuntu you can override to > 100% volume). Keyboard is pretty unsatisfying to use also.

I got it because i wanted a 14" laptop and it was the only one on the market. Screen size is perfect (15" is a bit big for travelling & carry on luggage)

This looks like the laptop i've been waiting for

Not OP, but got the same laptop. "Jumpy trackpad" [1] and "stuck key" [2] problems are the ones I feel most.

They should have been fixed by the latest firmware (apparently still in 2015) but I can still experience them sometimes. I believe I have the latest fw (I'm surely >= 06A), but can't check ATM, so chances are I'm not on the latest.
Then again, I admit I can work with it almost seamlessly (dev-work from CLI mainly).

> By the way, why do you think wealthier people shouldn't get more advantages in life?

He's not saying that. The idea he's espousing is closer to the idea that there are lots of talented kids in poor districts that get completely left behind because they live in a poor area. The only way to solve that is to provide some funding, and funding is scarce in poor districts.
Only a few samples, but:

- Restaurants seem to keep them up. They need to post menus, and links to OpenTable and other reservation sites.

- K-12 Schools keep their own sites

- Other small businesses (martial arts schools, dry cleaners, etc) seem to be leaving their old sites on standby. Big drop in forum activity.
As someone who also hand-coded a neural network implementation, forward and back prop as well as an RNN in C, yea "raw numpy" is a joke.

Something I've always hated about people that say "why do I have to write a backprop when TF does it for me?"

Here's why: you go to a company, they want you to incorporate machine learning into their c++ engine. Have fun using numpy, you said you knew machine learning right? implement backprop for me, you can do that right?
I've had an employer suggest it before... I had a similar reaction.
(Czech republic) - in my peer-group, fully remote work is rare, but not unheard-off (for past two years I have worked with colleague who was fully remote, even though he lives in the same country, and we are about to hire another one. Both of them were hired as senior engineers)

What is really common, is reasonably generous attitude towards working from home. Few of my colleagues have arrangement with my manager that they can work from home indefinitely and basically come to office only when they feel like it, because of ~1h long commute from one part of the city to the other. Company policy is 1xWFH/week.
Hm, I've ordered loads of inexpensive stuff on AliExpress as well, probably around 30 orders. The only problem I've ever had was that I received the wrong item once (DHT11 instead of DHT22), and the seller promptly refunded it. I mostly buy electronics components. It does require a bit of careful reading to know what exactly you're buying, though.

Even though I flagged the HN post as it's pretty much spam (a direct link to Dell's product page and not a review or analysis of the device), I have to say that in my experience Dell's XPS line is pretty much the gold standard for Windows alternatives to the MacBook and MacBook Air. The only other lightweight notebook that comes close is the Asus ZenBook, which directly competes with the MBA and is a pretty amazing machine for the price.

I've seen this. Google's changes to search over the years have made it increasingly difficult for an SMB website to show up in organic searches. Google seems to be biased towards big national brands in a way that they weren't in the past. That, of course, led to more bidding for AdWords, which drove the pricing up there.

So, SMB owners then try to find some other way to get a presence, many of which make it difficult to use your own website. Facebook, for example, is setup in a way where your FB biz page is highlighted, but the url to your actual site is obscured and buried.

Aside from your examples of Facebook, Instagram, and Twitter...I've also seen SMB's move their ecommerce sales to Etsy, eBay, Amazon, and the like.

When you're talking about fundamental education of your population, this is a pretty short-sighted argument. Under-education means fewer skilled workers and more bad decision making, both of which will have an impact on Mr. Rich. Mr. Rich has a personal interest in ensuring a good education for everyone.
That whether an element was found in a list or not has nothing to do with the order relation on the type of indices. Conceptually, it's a completely distinct case; in a more solid type system it would be captured by an option type. This becomes especially evident when you attempt to generalise this searching operation to arbitrary maps.
Why on earth would you do that?

If you want to prevent users from altering their time use your server and do a time compare with your server.

NTP can be easily intercepted and altered so it would make a lot more sense to do this via a encrypted certificate pinned communication path increasing my work load drastically to alter the time.

Trackpads (buttons) on thinkpads are not well designed and I doubt anyones mental health who says otherwise.
You can have Big-O of worst case and Big-O of average case. "Asymptotic complexity" itself does not imply worst case; the assumptions you make to construct the function itself determine worst case or average case.
Exactly. This is the myth that just won't die. If there really was a talent shortage, wages would be going up and up until supply met demand, and/or companies would become a lot less picky about their hires than they are now. You can't say there is a shortage of something without naming the price you're offering. Otherwise I could say there's a shortage of new Teslas because I can't find a lime green one for $10K.

Foldist is a tool to fold clothes and let the clothes stay folded until we want to wear them. It is fun and simple to use. It acts like a spine of clothes so different kind of clothes can ‘stand up’ and be organised like books with the help of Foldist.

property taxes in the suburbs of denver are on the order of .5% a year. compare that to the suburbs of chicago where they're north of 2% a year. the school quality and education provided are AT LEAST SIMILAR.

the difference in cost is a product of two things: pensions and legacy costs (overly rich in chicago), and population growth. chicago has become a game of musical chairs where the last man standing has to pay the retired teachers. north shore property values reflect this reality.

Yes, thank you, the third party library that Snapchat used without even thinking what it does by using some (wrong!) defaults. I thought it was obvious from the links I've given. I've edited my posts to name it as such.
I wasn't at first either, but benefits outweigh the risks (which are all security related).

It's something I'm willing to re-think if it turns out to be problematic on any level. But so far after half a year in production, we've seen no problems.
Never too late, but you'll need to prove yourself. That's hard since you don't have a work history or things to talk about.

You'll be competing with younger folks for entry-level positions. I'd consider a portfolio of code or personal projects on Github/etc. that show your style, coding and otherwise.
