“What’s the number after F in hexadecimal?”

My first reaction to this was: "Damn... where's my ASCII table?"

Because this question can be taken two ways: "What comes after f in hexadecimal notation?" and "What is the UTF-8 code for 'G'?"

A very important thing to keep in mind for both sides in an interview is that misunderstandings will happen, for the most mundane and obvious things. How you respond to these will determine your success in interviewing. Give the benefit of the doubt until the other party has conclusively proven that they don't know what they're talking about.
There's historical basis and case law to suggest that IQ exams have been used as illegal barriers on race, and it's not too far of an argument that your test could also be discriminating against a protected class. And it's potentially horrible PR.

> What is required by Congress is the removal of artificial, arbitrary, and unnecessary barriers to employment when the barriers operate invidiously to discriminate on the basis of racial or other impermissible classification...

> On the record before us, neither the high school completion requirement nor the general intelligence test is shown to bear a demonstrable relationship to successful performance of the jobs for which it was used. Both were adopted, as the Court of Appeals noted, without meaningful study of their relationship to job performance ability. Rather, a vice-president of the Company testified, the requirements were instituted on the Company's judgment that they generally would improve the overall quality of the workforce.

> The evidence, however, shows that employees who have not completed high school or taken the tests have continued to perform satisfactorily, and make progress in departments for which the high school and test criteria are now used.[8] The promotion record of present employees who would not be able to meet the new criteria thus suggests the possibility that the requirements may not be needed even for the limited purpose of preserving the avowed policy of advancement within the Company.

> In the context of this case, it is unnecessary to reach the question whether testing requirements that take into account capability for the next succeeding position or related future promotion might be utilized upon a showing that such long-range requirements fulfill a genuine business need. In the present case, the Company has made no such showing.
Finally a car company that gets it. Touchscreens and cars should be mutually exclusive, anything that takes your eyes off the road in a car is simply dangerous.

Feedback could be visual and in extreme cases audible. Input should be tactile, so buttons rather than surfaces.

And screens should display only a little bit of information, in a font large enough that you don't end up straining your eyes when you switch from the road to the screen and back.
Sure they had a system, commercial UNIXes would been kept being used.

GCC only got manpower when Sun changed the way UNIX SDK used to be given to customers.

And who knows, maybe companies would have been more willing to dedicate manpower to HURD.
A New Car UI (2014)
The thing though is that until recently, one could argue that China was going in the right direction... The liberal faction was much more tolerable to HKers... The current government with Xi Jinping is a relapse to a more despotic regimes...

It's also not true, Chiang Kai-shek's son inherited the power from his father but paved the way to Democracy so sometimes despot regimes actually do progress for the better.
I don't know what the problem is or how to fix it, but every car UI/UX I've ever tried, from Audi to Toyota was an absolute repulsive nightmare. Even while not driving it takes forever to find a way to any basic function - while in regular life the phones, and most other electronics are sub-second mostly intuitive. Major car makers always feel like they are two decades behind! And everyone insists on their own separate rat-hole of an experience. We shall see if Mazda's does any better, but the touchscreens I've interacted with in cars were completely maddening, an ugly pixelated blast from a very slow past even in brand new cars.
Not especially knowledgeable, but one factor in the relative lack of interest in other gates might be that NAND and NOR are the only two universal gates which treat their inputs equally. The others ("A and not B", "B and not A", "A or not B", "B or not A") behave differently if you swap A and B, whereas NAND and NOR are symmetrical under that operation.

Edit to add: Incidentally, I do remember reading one logic text where boolean algebra was defined in terms of, and built up entirely from, the "B or Not A" gate, which the text called "if" or "->"

It is only false when A is true and B is false, which matches what logicians expect from a conditional statement, for example: "if it's raining then it's cloudy" is only contradicted by the combination of raining but not cloudy. If it's not raining, then the statement is not falsified whether there's clouds or not.

You just learn how to solve some kind of problems (series of images, series of numbers and so on) etc.
This obviously does not make you "smarter", it just makes you good at solving some kind of puzzles.
But "smart" is ill defined and vague anyway..
> Good. There is a reason you don't see apple like designed plane cockpit.

But Mazda's cockpit isn't plane cockpit either. Please go for a test drive with new Mazda 3 and you will be surpised how stupid is this decision.

If you want to volume up, change a song, yes, it is easy.

But if you want for example turn on GPS navigation, you need to use this wheel near the gearbox to:
- leave a radio interface (you must look at screen and turn the wheel at the same time)
- find where is a navi (by turning the wheel and pressing it, still looking at the screen)
- choose, again with the wheel, to start typing your destination
- and what most: again with wheel (turning it and pressing) type the address simultaneously looking on an onscreen keyboard.

All that while not looking on the road and holding your steering wheel with one hand and another on navigation wheel on central canal.

How come this is safer by tapping on the screen?!
Isn't the surveillance/telemetry problem still as much of a problem as it was on day zero? As far as I know, it hasn't been removed nor lessened. As far as I remember, it is absolutely overreaching, collecting your name, email address, browsing history, searches, application usage and more.

The global trend for Apache is not looking good, and I believe a large part of its popularity is simply a legacy of its dominant position a decade ago.

Over the last 10 years, it probably lost half of its share. The exact figures vary with the source: according to the link below, Apache's share of the million busiest web sites went from 66% in 2011 to 32% now.

I've never seen anyone buying meat or checking out the meat section at Costco so I just assumed it was the same stuff at the grocery store, except overpriced and in restaurant quantities.

Show HN: Build your own automatable, Phone controllable watering system for 20$
It's hardly controversial that whatever Wilson's ideas were, they did not include Texas becoming an independent country. I also don't think it's controversial that all the intricate thinking, principles and international proclamations on self-determination don't actually boil down to 'any group or region can easily turn themselves into a sovereign country, if they really want to and work hard at it'.
I needed a pair of Lithium AA batteries. I saw them in stock at Walmart.com (available for pickup today), so instead, I dropped by the store to grab them.

I checked all of the battery displays, but couldn't find them. (I found Lithium AAA.) So I ordered them online.

The next day, I got an email: "pickup order delayed, don't go to the store yet." A few days later, same thing. A few days later, "our apologies, your order has been canceled".

I've had this issue 2 out of 5 times. Not great inventory control.
Ah, I can confirm all of the issues. I've thought that was my fault - so these are probably bugs.

It's a bit insane that cars (as far as I understand it) have to go through a lot of certification, e.g. that their airbags work, or that the controls work properly (e.g. that the brake-by-wire doesn't have bugs), but that only now have they done research if touch screen usage is safe or not...
This is a problem for the advertisers, they don’t want their most valuable prospects walled off by adblockers.

My guess is we will see much more sponsored content as a response to this.
It's a case of picking the right tool for the job, touchscreens aren't entirely awful. But if I'm driving and I want to switch to Radio, the button should always be in the exact same place so I don't need to think.

My car has buttons for all these operations and it's great. What is bad for is browsing the map when I'm parked; say I'm looking for a car park near my destination, by the time I've zoomed out with a scroll wheel, browsed around and zoomed back in a few times I could've done the same thing on my phone and set off.
You mean "React Components" right? Nice effort, but please mention that these components are supposed to work with React. If we now use the word "Component" as a synonym for React, you make it look like there are no other frameworks than React.
Depends, do you have ~$500 to spare?

I ask because the single best book on cybernetics (and I mean it, it feels a tad bit absurd how much better than other works on the topic it seems to me) costs roughly that, isn't available on Libgen, and nobody dares mention it anywhere in fear of driving prices on
used copies up, because nobody wants the publisher to get any money for it, cause while they sure charge a lot for it, they actively hampered efforts by the original authors for a new edition of the book. (The rights to it eventually did end up in the right hands - a decade too late.)

If you wanna know why we don't see widespread adaption of systems thinking, it seems almost singularly caused by the nega-butterfly effect of that book not sitting on Libgen & having a price tag on it so gigantic people don't even wanna talk about it.

So ironic, makes me want to puke.
Be free to make your own mind. The Chinese are making their own mind, right? So what the fuss?

The most funny part when the US or other western countries point fingers at Chinese having insufficient information of misinformation to decide for themselves, is that a significant portion of their population still believes in God, and in US specifically, people believe in Creationism.

I don't know, information is just information and can be manipulated and interpreted in both ways. Is abortion a choice of the mother, or a violation of rights of the child? Are guns tools to fight oppression or ways to kill innocent people? They're both, but each side sees the other side as heretic and intolerable.

Now, don't the Chinese people know there's corrutption in the country? Don't they know there's censorship? Don't they even joke about it? US has problems and people talk about it. China has problems and people talk about. In public. On the Internet. China is not how you think it is, no need to paint it as a monster.
30 years ago was tiananmen square...

Article is mostly fine, but the author does some effort to mention CPython-specific things, but not consistently, making it a bit of a confusing read for when you've worked with different Python implementations at the implementation level (C in my case). E.g. Each object contains at least three pieces of data: Reference count well, in CPython yes but not in implementations which use mark and sweep GC.
I assumed since 2001, that soon a car will be made, where all the functions can be accessed with eyes still on the road. Just from the wheel, like the paddles, and buttons for thumbs on the wheel. Anything extra, just place your hand slightly from the wheel and immediately feel what you are about to switch and adjust. Imagine to access any function of the car in complete darkness just by the feel.

None of this bullshit, where buttons are far from each other, moving hands up and down left and right to change temperature, turn air-conditioning on/off. Where driver needs to glance down to steer hand into damn buttons. Where "infotainment" needs to show you anything at all about what you are listening to - as if you dont hear it. Keep information to a minimum, ffs.

Then we got touchscreens instead - now you cant even drive in full darkness and feel some buttons with your hand to adjust. There is not even a Night Mode.

Are car manufacturers really this bad? Yep. Tesla included.
They’re called consultants.

Every repackaged fad in software was pumped and sold by high paid consultants looking to sell the next buzz word to some big company who doesn’t understand software.

A bunch of them even did it to “lean startups” here in Toronto and attempted to apply it to absolutely everything where it didn’t fit or was just lightly repackaged agile. They use it to get gov ‘innovation’ credit here too which is another cancerous industry full of buzzword consultants.

Only occasionally by luck or in small hard fought increments do things actually get better via these hype trains.
Lobbying from the advertisers?

I personally don’t think it’s very likely, for one thing I expect most of the staff at the likes of Google run an adblocker.
It must be said that the Captur on board software is hilariously bad. (I have a 2018 captur) it's not that it's entirely dysfunctional, it's kludgey and painful.

It's not only the superiority of physical buttons, carmakers seem to be bad at simple, distraction-free UI.

- A single UI task (cancel navigation, switch radio station) takes 4-6 screen presses through some dialogs/menus that have only one option

- the thing responds too slow, there are some superfluous animations and in general there's long delays between presses and feedback on the screen that you touched something.

- Random crashes when not doing anything besides driving

- Random crashes (more frequently) when using android auto or making phone calls

- Updating the software takes 30 minutes, during which no information is shown besides a randomly resetting progress bar.
We are not paying you to SOLVE the problem with those constraints.

We are simply evaluating how you APPROACH a problem with those constraints.

If given such a problem, you throw your hands up in the air, or give me a lecture about how such a problem does not occur in real life, or how it doesn't represent your best-self, that itself tells a lot about you.

My question, as I repeat in other comments is this : WHY do you feel stressed ? Delve into your psyche for just 1 minute and it will boil down to - fear of being judged as incompetent. All we are looking for is someone who can set aside this fear TEMPORARILY.
You don't feel pressure if your mom throws you this problem, right ? Can you do the same even if a million people are watching, but just for 2 minutes ?

Even if we throw you a NP-Hard problem, can you objectively spend 2 minutes thinking about it, talking another 2 minutes about how you'd approach it, and then saying, 'This looks like it's beyond my skillset' - That clarity of thinking, mastery of fear, and blatant honesty is worth a hundred github apache open source projects.

People who can't do this lack the maturity to understand that in real-life, nobody really gives a damn about our achievements and failures except us (and very close relatives of course).
Considering the current advances in solar technology, I think we'll soon hit the point where a local power grid powered by solar panels and batteries will be more efficient for people living a bit remote, and I do believe that we will see a larger amount of people living "off-grid" in the rural areas of the future.

Communications networks are the big problem, but sattellite-based solutions like Starlink might help in that regard.

Problem is that none of it will help if the Sun decides to throw a bunch of star stuff our way; local grids will be just as fried as the big ones, and it's better to make sure people are able to survive on their own without electricity for at least a few days.
A referendum today is too late..

But if the UK had called one, it might have been different.

We've successful solved territorial disputed with referendums in Europe. We just rarely talk about it, because there was no war to talk about :)
Touch screens in cars are the equivalent of shiny phones. They persuade people to buy and some of them might love them.

Nearly every phone I see has a protector around it, destroying the nice looking design because one drop and it breaks. But you still need to have shiny designed phones or you won't sell them.

So cudos to Mazda. I wonder if they can keep this policy up when everyone else has shiny large touchscreens.
Then MB/BMW approach of having a touchpad near your wrist is perfect - you can draw letters with your finger without having to worry about hitting miniscule letters on the screen.

Really lazy reporting. We need the total to know how much $2B really matters to Broadcom.

Putting the math on this here for everyone else:

> Huawei accounted for about $900 million, or 4%, of the company’s overall sales last year. Broadcom, however, also said the forecast cut “extends beyond one particular customer.”

So total sales were 22.5B and a 2B hit is indeed pretty bad!
It’s slightly better to load the (often wrong) blogspam answers into a box than to link to the blogspam, although in doing so, it gives the wrong answer more authority. It’s much better to actually spend resources to filter blogspam from results and link to quality sites which have done actual research.
> At first it was "repeated harassment" and now it's "incite to dox and harass."

It's always been an accusation about pattern of behavior, which includes multiple ("repeated") events that happened over the past (if I recall correctly) ~2 years. Some of these events involved Crowder using hate speech, which is not "calling people nasty names". Hate speech restrictions and laws are generally defined to target speech/writing/conduct/etc that incites violence or prejudicial behavior against a protected class. Calling some a well known slur is (probably) just being an asshole. When people talked about Crowder's hate speech, they aren't talking about him using a specific word; they're talking about how his rhetoric seems to be having the effect of inciting parts of his audience to attack Maza through his phone.

> It's now okay for John Oliver to go after organizations

Yes, of course it is. Attacking organizations (public or private) on matters of public interest is one of the primary goals of protecting the freedoms of speech and the press.

> he very clearly goes after the President

What specifically are you accusing John Oliver of doing with regards to the president? I doubt he say anything that would even theoretically qualify as hate speech, but if I'm mistaken, I would be interested in a link to any example of John Oliver inciting his audience to harass the President because of the President's race, sex, religion, or other protected class.

> ambiguous predicates

The only ambiguity I see is a lot of people misusing the term "hate speech".

> Crowder is extremely clear about his views on not harassing or doxxing,

I know; I do actually do my research about a topic before getting involved in an argument. Saying tht harassment and doxxing are bad is step 1. If he actually wanted it to stop, it would be a good idea for him to publicly condemn the those in his audience that were responsible for the harassment/etc, and work to avoid similarly inciting his audience in the future.

However, saying a few words against harassment and then continuing the behavior that he now knows could cause additional problems in his audience is at best irresponsible and reckless, and at worst makes his statements about harassment look suspiciously like a like or dog whistle.

> but it's clear that you haven't even done me (your opponent in this debate) the courtesy of some basic knowledge-gathering.

Warning: this kind of personal attack is against HN rules.

> I also think that assholes have a right to be asshole

I agree. Which is why the accusations against Crowder are bout the behavior that is significantly worse than simply being an asshole. Harassment and hate speech eventually lead to violence when ignored.
If the WSL is the only reason windows is a decent development workstation, then why not just use Linux in the first place? What unique factor is Windows offering here?
Without knowing the scale it's hard to answer this. But in general HAProxy is THE layer to sit in front of web servers. From DDoS protection rules to a true set of metrics and a real dashboard (good luck w/ Datadog metrics for Nginx), it's purpose IS to be a highly available Load Balancer/Proxy.

Nginx in comparison is for me, THE thing to use as a web server. When it comes to being a single layer away from reverseproxying requests to apps running on an instance or static file serving with caching rules Nginx is purpose built for this.

Both apps have support for what each other do though. For the more pedantic it's easy to say "But x can do this too with this feature". Usability wise though, nginx and HAProxy are distinct. I went through the comparison very recently while testing setup of HAProxy as a load balancer in front of multiple webservers running Nginx which in turn sat in front of several apps running on each instance.

TL;DR - At a slightly larger scale (scale being number of instances + apps) HAProxy and Nginx are great to use together as opposed to one over the other.
