Facebook Internship Interview Timelime
Hi all,

I had my coding interview with Facebook (round one) 2 days ago and was wondering (for those who've gone through the whole interview process) how long it took for the recruiter to get back with feedback/ results/ whether or not you're progressing to the next round?

Cheers.
Any laptops with taller than 16:9 aspect ratio?

16:9 is so short for a 13" and even a 15" is so much better at 16:10.

They could be invasive, by monitoring even when there's nothing going on, but there are well-defined rules and strict protocols in place, and I have never heard any cases where they have used the data to attack anyone personally or are there?

I don't agree, at least in the case of India, there have been other places to put your money for a long time. However all of those require funds that have known sources and on which taxes have been paid. There is a huge amount of funds in India in the "parallel economy" which can not be invested in these funds, the only options are to hold as cash or invest in real property (land/gold). Historically gold has been a good investment in India. See https://www.apnaplan.com/gold-price-in-india-40-years-histor...
I feel like the Surface Pro packing is ideal, super light 2 in one, 3:2 aspect ratio. If only they made one larger than 12"
I'm the progress of doing that right now. It's sweet. So sweet.
I expected replies to my comment with links to those sites, you do know how hard they shill tesla right? only recently elons been reeing at the very author of that elektrik article

Also, how did you manage to get shamed into being de facto anti-Tesla by social media trolls. Jeez …

but.. im sure the numbers are thoroughly researched...
> you denigrated my work in a public forum without apprising me

I'm sorry, I didn't realize I was under any obligation to apprise you. You certainly never asked me to, and if there's some kind of universal social obligation that applies here that's news to me. (BTW, did it even occur to you that the reason I did this is not because I'm a coward or a drunkard, but simply because I might be clueless?)

> the harm you inflicted would have been done

What harm could I possibly inflict? I have no influence in the quantum computing community. I've never published anything in that field, and I've been retired from research in general for nearly 20 years. No one who matters has any reason to pay attention to what I say. The only way my critique could possibly harm you is if it has merit. (Does it?)

> What if I went around in public forums and said, "Hey there's this crackpot out there, Ron Garret, check him out on your bogometer"?

You mean like when Lubos Motl called me a "category 5 loon"?

https://motls.blogspot.com/2012/10/evading-quantum-mechanics...

I was actually flattered that someone of Lubos's stature would take notice of my work and put forth the effort to criticize it. I think it said more about Lubos than it did about me that he chose to lob an ad-hominem at me, but whatever, it's a win-win for me: either Lubos is right, and I learn something, or he's wrong, and I get to be smug about having taught him something. :-) It's certainly not worth getting upset over.

> You introduced the term "quantum supremacy" to our discussion.

That's true, but I introduced it in the context of a question: are you claiming that you have achieved quantum supremacy in a classical computer? To which you answered yes.

> I don't usually think in such hype-y / marketing terminology,

Quantum supremacy is not "hype-y / marketing terminology", it's a technical term, whose definition is common knowledge in the quantum computing community:

https://en.wikipedia.org/wiki/Quantum_supremacy

I assumed you knew that, but apparently I was wrong. (In retrospect, I guess the fact that you had to look Shor's algorithm up on Wikipedia should have been a clue.)

So... now that you do know it, I am going to ask you again: are you claiming to have achieved quantum supremacy on a classical computer?
This is a summary of my ‘Aha!’ moments with Git. Once I learned the internals of Git life became a lot easier. I pretty much stopped looking up commands, as the concepts got internalized.

I thought it might help others too (and my future self), so I put them down.

If you're looking for commands, you'd be disappointed; if you're looking for concepts and insights, welcome!
If you don't mind, I was wondering what payment system to you use for the subscription stuff? Is it something like Zuora? Or did you have to build it from scratch?
>could sell for quite a lot of money, strengthening Tesla's finances

yes a trustworthy company run by a well regarded ceo that could raise money

tesla? not so optimistic. until tesla finds significant backing they're just going to keep playing the desperate cash pump game

im all for it tbh, its hella funny
Just to add onto this, I often write the sort of lead in paragraphs the GP describes last or nearly last. So it’s absolutely not the case that I used them as a way to clear my mind—the primary point was already there, I just wanted to introduce it a different way.
Some also argue that executing UI logic of every widget is wasteful. This might indeed be a concern when implemented poorly

For a game, which is already quite busy even when "idle" (and there are probably other things going on in each frame which take far more CPU and GPU to render), it won't be much of a concern; but with an application where most of the time is spent waiting for user input, spinning the CPU to re-render the GUI every frame is very energy-inefficient.
Ask HN: How to get this fraudulent copy of our website shut down?
I run AutoTempest.com, a car listings search engine. A few weeks ago, someone registered autoStempest.com, with an extra 's'. They copied our logo and branding, as well as faking other information, such as their team and location. (For example, their "CEO" is actually the CEO of Edmunds.) They've taken other steps to appear legitimate, such as creating a fake Yelp profile and reviews.

From what we've heard from our users, they're creating fake craigslist listings, and when people contact them, they're directing them to links on their site, claiming to be "Auto Tempest". Then they solicit payments (presumably reservations or down payments, if not complete sight-unseen purchases), while using our name recognition to gain trust.

We've determined that their registrar is Namecheap (as is ours, coincidentally), and they are hosted by a company called Quasinetworks, NL. Interestingly, if you google that company, the first result is someone complaining about how they were unresponsive to abuse notifications; not a great sign. We did sent a message to their abuse contact, but haven't heard back. We also contacted Namecheap and did get a reply, but it appears they will only take down a domain with a) a court order, b) potentially a request from law enforcement, or c) a UDRP proceeding: https://www.icann.org/resources/pages/help/dndr/udrp-en

The problem with options c or especially a is that they're costly, and nothing would stop whoever is behind the site from simply registering a new confusingly similar domain. So, to start with we've submitted a report to ic3.gov, the FBI's Internet Crime Complaint Center. Hopefully if they confirm the site is fraudulent, they can request that Namecheap yank the domain. I've never submitted such a complaint before though, so I have no idea how responsive they are.

Is there anything else we could do to shut these scammers down?
High-quality ones take longer to show up. They're harder to write.

I have been using the brave browser for a few months now. I think the concept is great, and possibly one of the best uses for crypto currency. In my case I want to disable ads entirely and use the auto-pay system to pay publishers directly when I read their content. It also has a "tip" button so you can send extra with one click if you really like the content.

Edit: There seems to be a ton of negative comments in this thread from people who have never actually used the Brave Browser. I would encourage anyone who is interested to actually install it and try it. The ads section is completely opt-in. The "auto-contribute" and "tips" features can be used without the ads. I feel the "auto-contribute" and "tips" features are what would really appeal to most HN readers.
Cloud data and email are protected by the Electronic Communications Privacy Act:
https://en.wikipedia.org/wiki/Electronic_Communications_Priv...

Under the ECPA they need to obtain a warrant for email and other cloud storage services, unless it's older than 180 days... then it's considered "abandoned".

There's been some effort to remove the 180 day limit.. some states have laws that protect older data + the 6th circuit already extended it past 180 days in US v Warshark.. but we need a national law like the Email Privacy Act that the House passed last year (but the senate didn't):

One hopes.

But what's the success rate for internships?
Some other fun examples of points in the music notation space are the various notation systems used by traditional Japanese musical instruments... For instance, the shakuhachi (a type of bamboo flute) has a system where various combinations of fingerings/blowing technique are each assigned distinct characters (the same pitch, but achieved with different fingerings, and therefore having different tone colors, will have different characters). Rhythm and ornamentation are then indicated with various annotations on these characters. You could maybe make the analogy that Japanese music notation relates to Western classical notation in a similar way to how Chinese characters compare to alphabetical systems...

Other instruments have similar (but generally mutually unintelligible!) systems, with different characters assigned to particular notes/techniques peculiar to those instruments.
Or just use regular Vim and not think that everything needs to run inside of a web browser, especially if you value user privacy and computer resources.

Well the weird thing is Panasonic is complaining about not selling enough batteries. Seems kinda crazy considering the rapid scale of Tesla's ramp up, not to mention secondary uses like powerwalls and grid sized battery systems.

The resolution of this also brings up why people dislike NPM. It's no longer about the whole open source thing anymore. What you put up there stays up there and isn't really yours anymore.
We changed the URL from https://www.wsj.com/articles/nsa-recommends-dropping-phone-s... because WSJ seems no longer to have a paywall workaround. If someone can suggest a better URL, we can change it again. I just did a Google and picked the first link I found that wasn't illegibly crammed with ads.
This fits into the category I saw a reporter describe as "Things 20 something engineers wish their mom still did for them."

Congrats on your progress! I assume you still have metabolic syndrome (have you gotten your fasting insulin tested? What's a shame is most doctors test that, which is a $30 assay and the only way to calculate HOMA-IR or QUICKI IR estimates).

While I can't disagree w/ Metformin/Berberine being effective for glucose control, I personally don't think that they aren't great long term for the dysbiosis, B12-deficiency (for metformin) and toxicity (for Berberine) effects... https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5478780/

Most people that haven't long-term diabetic (eg, completely destroyed beta cells) should be able to get their health back in order via primarily dietary interventions, although it may require some detective work (conscientious dietary, blood work, body composition tracking).

Some of the hypertension may require addressing the IR, which can just take time to resolve: https://www.ncbi.nlm.nih.gov/m/pubmed/3299096/

Some of it may also be insuring adequate electrolytes, most people are much too low on ketogenic diets: https://blog.virtahealth.com/sodium-potassium-magnesium-keto...

I think waist:height ratio is definitely the best home measurement, but hopefully you're getting good supporting bloodwork as well, which can be very helpful in helping diagnosing problem areas. Also I found DXA and RER testing to be personally quite useful as well, especially for tracking progress on visceral fat (I took off 25% of my body weight off starting last summer). Good luck!
It seems like there’s a gap in the market for a hard-nosed, teaching-first university. A place full of passionate professors with high standards. A place where high school valedictorians work their ass off for a B. A place where you feel your best will never be good enough because the standards are impossible... until, one day, you get an A. And that grade MEANS something. And after four years, the students walk out into the wide world and kick ass up and down the street.

Somebody get $100M and start recruiting all these great professors academia can’t handle....

>Like, if someone treads dog poo into my house on their shoes, it doesn't really matter if they did it by mistake, or spent ages walking around town trying to find some dog poo to step in before coming to my house; the effect is that there is now dog poo on my carpet.

So, whether it's your own two year old or a malicious adult, you think it's wrong to respond differently because they both produced the same harm?
Roman metallurgy was really not at a point to make practical use of steam power on a scale that made it more effective than using slaves. Crucible steel, a bare minimum, wouldn't come to Europe for over a millennium. They simply did not have the materials engineering to build useful pressure vessels.

People get weirdly romantic about how easy these ideas would have been to implement; there's this weird conception that we should have been able to go from late antiquity Rome to early industrial revolution England in a matter of a couple centuries.

This ignores two things. First executing seemingly simple ideas can still require incredible expertise in a range of fields. Nuclear bombs are conceptually simple but building them still seems to require the economy of a nation state.

Second, Roman knowledge wasn't lost. It was all still there in the Byzantine Empire yet strangely they weren't sending rockets to the moon in the 1200's. The centres of knowledge simply migrated, and in every place knowledge grew and expanded. Whether work by Byzantine or Muslim scholars, science wasn't put on pause and without their contributions, we would not have advanced to where we are today.

> For the probably best known example, Unity used to have an IMGUI [1] but they've actively moved away from it. It's still there in vestigial form, the API is not removed, but game developers don't really use it.

It's true that the newer retained mode GUI has supplanted the older IMGUI for "game UI" (e.g. what users interact with when playing an actual game built with Unity). On the other hand, the Unity editor itself is still built entirely with their immediate-mode GUI library, and I haven't heard of any plan to move away from that. Building "editor-like" tools (including custom user tools) is still significantly easier to accomplish using immediate-mode libraries.
How good are you at taking advice?
Roughly speaking, it's a "sane" subset. But it's also a large subset -- it aims to run all bash programs either unchanged or with trivial patches. So far that's been working out better than I expected.

Occasionally a shell script will rely on something really odd, but that hasn't happened too often. For example, arithmetic in ksh/bash has some really horrible corner cases, but nobody relies on those. They mostly just increment counters and so forth.

OSH also has some features that bash doesn't have, so it's not really a subset.

Eventually there is supposed to be a legacy-free shell language called "Oil", but I've had my hands full with OSH, so I don't have much to say about that. But I think replacing bash is more important than creating an incompatible shell language that probably won't get used!
Yes. I believe they shifted to putting it in your car in driveway
Reading the article gives me the same feeling as trying to understand typical highly overabstracted "enterprisey" code, which seems rather fitting given the title.

> Western buyers tend to stay away from UAE gold

Do Western buyers even buy gold like indians do? Most of Indian buys 22k jewelry. In India, no one knows about accridated. Indians love UAE gold. Lot of indians from USA fly through Emirates just to buy gold from UAE. Indians thinks that UAE gold is more pure than what they can get in USA or India.

It is supposed to be possible for publishers to spend their BAT on paying users to visit or promote their content.
I went to a top school and my observations in hindsight:

1. brilliant professors and peers were inspirational and encouraged ambitious and creative thinking

2. >90% of education is self-education

3. very little of what I learned in class prepared me for the real world and among my classmates there has been relatively little correlation between academic success and real world success
Even the manual feed robot from Foldimate would be a huge time save. Still insanely difficult, but would be absolutely amazing.

In Unity you're still forced to use the IMGUI for making editor tools. In fact their new xml layout prototype still uses the IMGUI to draw an instantiated layout! What a mess...
The number of definitions here suggest its not well defined, one more :)

A data lake is when you store your data in object storage (S3, GCS etc) as opposed to a filesystem (HDFS) or some indexed datastore (Redshift etc).

This potentially saves a lot of money because you can scale compute separately from storage, and object storage can be extremely cost effective compared to running a distributed filesystem.

Where the two overlap is when you store something like parquet in object storage, the file format is somewhat indexed already so you spend a bit more money preprocessing it but save a lot of money querying it.

I think whether its "raw" json or log files or preprocessed parquet doesnt really differentiate whether its a data lake or not
In this particular case they are using bits leaked from the nonce which changes with each execution, but they use lattice reduction after using these bits to generate hidden number problem inequalities[1-3]. They aren't exactly brute forcing the remaining unknown bits here but they do need to try running the lattice reduction multiple times over different samples of their guesses until it works.

In other settings, yes you can still gather leaked bits and use them to reduce the search space until it is small enough to brute force. I've had my own elliptic curve implementation broken through differential power analysis from a leakage due to a conditional branch just like the one in this paper. It leaked only a single bit and it was leaking a bit of the key or a nonce but the least significant bit of an intermediate value in the same way that the LSB was leaked in this paper. All I did was select one of two results, both of which were computed using the same number of operations every time and discarded the other based on whether a result was odd or even. Simply branching is generally enough to leak. After running many operations using the same key on different data you could reduce the search space down to one which could be brute forced in a few minutes. Both the OP's implementation and mine also tried to use some side channel countermeasures, but leaking this single bit was enough. You simply cannot use any conditional branching or memory addressing based on secret information [4-5]. Even being aware of this, it was not obvious how to avoid this conditional branch while implementing the algorithm (the math can be reformulated to avoid it).

We did find that randomized projective coordinates[6] significantly helped in our case (we had already implemented this but was disabled by default). This probably only makes it more difficult to extract the secret but it should be implemented in constant time.

Something bothers me about the author's notion that we don't have stuff from the "dark ages" only because it was ground up and recycled. Okay, but we do have stuff from before that time, that somehow survived the same conditions.
Off topic, but I recommend getting a subscription of The Economist. Totally worth the money, and the weekly format combined with an almost complete lack of bias gives a nice leisurely pace to catch up with world's events.
