There were a lot of "online writings" about WMD in Iraq, too.

Anyway, I'm not disputing that that keyboard has some issues. I agree with you. It's a crappy keyboard. But I was trying to discuss AirPower and the fact that it's a laudable, good-faith decision to just admit you failed with your engineering effort and you can't build the product you hoped to build.
>There has to be something that caused this abrupt cancellation.

They could have sold a Wireless Charger just like others with their mark up. Instead we got nothing.

Also admitting MacBook Pro Keyboard Failure. I believe there is something happening to Hardware Engineering in general.
>If comprehensive static proofs are in the picture, there's little benefit to running trusted code in user mode. It's just adding a protection boundary to something that could already be proven as safe via static analysis.

Try seeing it the other way around. It minimizes what needs proving (it isn't cheap) by having the microkernel (small and proven) enforce separation.

Capabilities (not to be confused with POSIX capabilities, which are something else) do help massively here. Refer to the Genode Book[0] introduction chapter for an introduction to capabilities.

In the driver example, running the driver unprivileged means the damage a faulty driver can be contained. In combination with a iommu, it can be made so that the hardware can only talk to the driver, to complete the protection. This is only possible if the kernel itself can be trusted, which would mean the kernel has to be proven, and that's unrealistic unless it's a microkernel, as it is a very costly process that doesn't even scale linearly with LoC.

The alternative is to make all drivers part of the TCB, which isn't realistic for the same reason. Unfortunately, on top of this, driver code quality is known to be particularly bad.

Here we go! This is the first minute or so of Penny Lane by The Beatles converted down to a 10KB .bin and then back to a .wav: http://no.gd/pennylane.wav .. unsurprisingly the vocals remain recognizable, but the music barely at all.
I suspect you're right - we probably got a bit caught up in best practices to our detriment. Thank you for this.
I was referencing the video I linked.

> My larger point is that PragerU is not "extreme right wing" content - that's hyperbolic.

If you replaced it with "very conservative" or something in the original comment, the whole point would still stand.

> we should put no stock in those from the left continually complaining

"The left" isn't doing anything, a specific individual commented.
Mars, flat? It has the highest mountain in the Solar System, Olympus Mons. Plenty of rugged places on Mars that outshine anything Earth can put up.

But yeah, we probably wouldn't put a base those places, not initially. Though I wonder if a volcano base would tell us more about the planet's interior...and its fairly flat including lots of high walls to protect against winds/storms?

Some Starbucks did this for a while as well, provided adapters for USB micro / Lightning and had chargers at the center of every table. Not sure if they still do.
I don't know. I'm not sold on single payer either, mind you. The only long-term solution I can really see is for the Republicans to fail at repealing the ACA so many times, and for public opinion to be sufficiently against them, that they basically give up.
For those criticizing the article, I wish I could have invested in a lot of companies but can’t because I like many can’t due to 1) not being an accredited investor and 2) even if you are accredited you cannot easily buy private shares (access issue)

If they felt they could not deliver a quality product, and decide not to release it, what is the big deal
For what it's worth, I use it extensively on several different platforms, and have never had a crash.
I hope you don't mind if I appropriate that phrase. Although for comedic effect I may change it to: money, like alcohol, amplifies your character. ;)
Not sure how this relates.

When I say "extreme" I mean "extreme" in all senses, not just politically extremist. Could be just an extremely one-sided view of something ("why X sucks") or even a "top 10" or "worst fail" video.
Depending on what form your equity takes, California may still tax you if you leave. For ISOs, it's relatively simple, if you're a resident at the time of the Federal taxable event, it's a California event. For RSUs and NSOs, it's California taxable for the portion of vesting that is California sourced: the time where you were a California resident, or working in California. (Caveat: the rules are vague, you're required to use a reasonable method of apportionment and work days is documented as a reasonable method)
It has been tried in commercial products, but it's harder than it looks. Pogo pin type contacts don't have a lot of current capacity and there are some fairly serious issues with surface contamination and corrosion. The layout is easy, the electronics are easy, but the metallurgy of the contacts is an unsolved problem.
You're one of the lucky ones; my 2018 laptop has unreliable "o" , "s", "h", "j", "k", and "e" keys (can you tell I'm a heavy vim user?), and the black plastic around the "K" glyph has started to wear away.
SV is not the only tech hub in the country. Others are also expensive, but not that expensive. And if you're willing to tolerate commutes as long as SV, then it can be much cheaper.
I have charger on my table and I just put phone there. It's not THAT MUCH better, but it's more convenient. Also I don't put lightning port to stress which is hopefully will prolong device life. I liked it so much that I recently ordered wireless charger even for my car, so I don't have to tinker with cables.
Forked software is usually reasonable, but for me, the sheer complexity of the graphical, interactive web sadly begets an exception for modern browsers. Even if much of the work is offloaded to the corporations backing modern free/libre browsers (e.g. keeping up with new web standards and technologies), it certainly goes without saying that rebasing with upstream or even just applying the latest security fixes is no trivial task I would entrust any browser fork with minimal developer backing with.

This problem is especially worsened with the kind of user base that firefox forks tend to attract, from what I have seen. These users tend to ask very high-level questions e.g. "is waterfox more secure than pale moon" and will usually blindly switch from one fork to the next based on poorly-backed, unsubstantial crowd opinion. No userbase means waning support + maintenance. If you ask me, I think in the very special case of browser technologies, it would be more beneficial if the developers and users of firefox forks directed their energies towards making generally desirable changes in upstream.
You are already at Goebbels level Nazism with blocking dissenters. Next they use 2A on you to defend their freedom. I support freedom.
they discovered that the carburetor design would cause the engine to sputter on high speed dives

That's great that you love your Surface Book. But to me, the hardware is only half the equation. I will absolutely not buy a laptop that runs Windows. Sure, I could put Linux on it, but then I'd lose the touch optimized UI. Plus, I prefer MacOS 100 times more than Linux, which I prefer 100 more times than Windows.

So even if Microsoft has made better hardware recently, there are still a lot of people like me that buy Mac for MacOS. And I don't see most power users abandoning that for a touch screen.
You might want to pay closer attention to the complaints about inequality. What that focus is about is the degree of inequality.

Most people talking about it are not actually pursuing a world of absolute equality, but a world with reasonable levels of inequality, and with regulations that make a rapidly increasing spread less likely. I.e. we want floor and ceiling not too far apart, and not rapidly separating. Which means UBI alone, or minimum wage, or any number of floor-focused things are not the answer. Neither is a wealth tax, or any number of ceiling focused things the answer, by themselves.
So why keep saying that, when you aren't claiming it's extremist? If I said "a person who plays with their socks every evening, pretending it's the royal family, might also make such an argument", that would also be technically correct, but I doubt I could get away with "just making an observation, not saying that's describing anyone here, just that it might".
Cheaper and will not automatically fall over in the case of a power failure.
They're really the only entity who knows how widespread this is, and is financially incentivized to address it. Additionally, my employer has probably 30,000 of these keyboards in service and it's not a significant issue.
>Aside from housing, cost of living isn't that different, at least if you don't have kids. Things you buy from Amazon cost the same. Maybe it'd be a different situation if I had children.

Transportation costs are much higher in the bay area than normal parts of the country. Gas is usually $1/gallon more expensive (bay area electricity is about 2x as costly as the national average), car insurance is high, and the congestion is substantial.
75% of venture-backed startups never return money to investors, let alone founders [1]. 44% fail after four years [2]. That's almost half a decade of your life. I'm sure the cash-out rate for early employees is even worse.

Starting your own company is not a rational financial decision. Neither is working at a startup. Which is the point.

After looking at the video more closely, I agree with you. It looks like slightly underdamped damped response in a PID feedback loop. Funny, how it ends up looking like an ostrich.
> I considered that, but I can't think of any plausible reason for prominent overlap in viewership of JP's moderate political content and extreme RW content

From my understanding, JP is actually pretty connected with conservative/right wing politics. Not so much that he is necessarily right wing himself, I wouldn't know, but that he has a large right wing following.

I think they like him for his opposition to political correctness/gender pronouns. His philosophy on masculinity also really appeals to conservatives rebelling against feminism.

yes, natural movements are approximately energy-minimizing. The optimal control algorithms used by BD probably have energy minimization as their main objective.
There are plenty of chargers out there. I don't think that many people would buy overpriced Apple ones, unless they would introduce some proprietary lock-in, but it seems that it's too late.
I completely disagree.

These people are already on openly visible platforms, such as 4chan and 8chan, where the Christchurch terrorist was radicalized.

By giving their hate and propaganda exposure on mainstream (social) media, you give them a platform to spread their ideology to more people. You have to realize that these people do not care about the truth, they do not care about debates, all they care about is being heard and seen.

Debating them does not work, it only gives them more exposure.

https://medium.com/@DeoTasDevil/the-rhetoric-tricks-traps-an...

The only way to deal with people who use these sorts of tactics is to deny them the "debate", deny them a platform and deplatform them from whichever platforms they already have. Shut off their access to the people they are trying to radicalize.

https://www.youtube.com/watch?v=wmVkJvieaOA

Obviously this does go somewhat against the "rules" for polite conversation and debate that we've all been taught. But there is no debate to be had with fascists, everything they say and do eventually boils down to "we will kill you". That is not an ideology you can reason with.
You're right that she doesn't say much about what she's done, but I think that wasn't the point of the interview. The interview was intended to explore the lifestyle of someone who grew up in a super rich family, and the questions are clearly worded to get at that. None of the questions ask about her accomplishments, so of course she doesn't talk about them.

> Your first interactions with anyone will set the tone for the rest of the relationship. If you crush the first emails, phone calls, or meetings, your reputation will be solidified for the long-term.

It is a weird world. The above has been consistent in the following:

1- In high school. If you just meet some new kids for a first time and mumbble stupidly, they'll think you are retarded and it'll be hard to change that view.

2- If you fail to impress your potential date in the first date, you are pretty much over. I think as a guy I'm more tolerable with girls but I might not be accurate or maybe an exception.

3- It still applies in adulthood. I think that's why doctors care a lot about their medical offices. I mean if you check a doctor with a messy office, no secretary and not so expensive equipment.

It sucks: The first impression matters a lot. You are allowed to suck (within limits) afterward but the first impression is a must.

> Until you’re sure of your effective tax rate, set aside a minimum of 25% of every dollar you earn for the tax man. Put it away, don’t touch it.

Try to maximize your business expenses. Can you make your gym as a business expense? Your "personal" car? Your mobile phone bill? There are lots of things you can expense. Check with your accountant. Have a list and let him check what can be checked to the business account.

My advice will be: Don't touch the business money until next fiscal year. That might be hard if you don't have a full year reserve but you can do the math and "borrow" from your company.
Honestly, I was never excited about wireless charging.

Then, on a whim when I ordered my Pixel 3, I put the stand in my cart. I didn't even realize it was wireless. I just like the nice look of a well-thought-out phone stand, and the feel of it in the dark when I read myself to sleep.

I then remembered that I replaced my old Pixel because the port had problems. Less wear on the ports is important.

Wireless is a huge deal for devices that require frequent charging.

Really good article filled with excellent advice! I actually started out down a similar path after leaving Netflix. For me, the biggest challenge for software engineers that want to go freelance will always be finding work (aka sales). It's just really scary to know that if you don't find another gig, you don't get paid.

Shameless plug: I ended up starting a company[0] to help freelancers/contractors with this. We are the sales and collections team for you. We focus on high-quality clients that can afford to pay for senior engineers. You pick jobs that appeal to you. We currently have way more openings for contract + remote jobs than we can fill and the clients are good (Vizio, Disney, Colliers). It's a great way to transition from full-time to consulting.

Is this not the most (or at least a) reasonable place to discuss? It would seem rude to walk into a club and ask 'why should you exist'.
Nah you're not fake news. You're really fake news.

I think you are overselling how exclusive IPOs are... There are plenty of investors 'only' worth millions, not 10s of billions (??? that's like 100 individuals world wide...), that get offered IPOs by large brokerages as a benefit.
Yes, mostly relevant for earlier employees of these companies that were awarded options that they’ve exercised but have not sold their shares (the taxable event)
You're right, I should never have brought politics into a discussion of violent radicalization. Those things definitely never overlap.

> I try to avoid pointers to pointers because of the redirection. They are not really solving a problem but only delaying it, at the cost of performance.

Passing an array index and doing an array lookup is also a form of indirection. How is that any different than passing a pointer and doing a pointer dereference? Either way you are not passing the value itself, you are passing a value that represents some kind of memory offset where the real data is stored. It's just that with the array approach, it is a relative offset rather than an absolute one.

> Using a pointer to access various kinds of information either requires that all this information is clumped together (loss of modularity)

Why does putting all the information together imply a loss of modularity? You could have structs inside structs, defined in separate files, and there would still be no need to dereference twice. Their values will just be stored as part of the enclosing struct's values automatically. You could even reference the specific sub-structs with pointers if you want to keep your modules unaware of the enclosing struct type.

As I said elsewhere on the thread, this rebuttal proves too much; unless you're really saying that it's structurally impossible due to the US Constitution or our unique culture to have decent health care, you'll have to do better than "anything the Democrats pass, the Republicans will try to repeal".
Someone posted an automated warehouse here a couple of months back. This looks like the one:

The robots were above the boxes instead of below the shelves (maybe to beat an Amazon patent? I dunno.) But that warehouse looks like nightmare fuel for a maintenance crew.
I count writing checks to charity as doing something with your life. If she wanted to do nothing at all except sit in her undies on the couch watching netflix and also give $70M away, that's a life well lived.
The US IT industry (as a lay person) is the only one where a startup can feasibly grow quickly enough to justify the investment.

Construction in the US is minimal. The initial costs of any industry with production, manufacturing are immense.
Healthcare is one area where there is space for clear improvement, but being a rigid to change as it is, healthcare startups really struggle to penetrate the industry.

You may invest in the service / food industry, but it doesn't seem to be as hyper-scaling friendly as it used to be. I do not foresee any trend since Starbucks that has been able to take a country by storm.
You can invest in smaller restaurants, but that is more of a small business investment than anything resembling stock, so good luck making it a liquid asset, even if successful.

Also, a lot of investments are mislabeled (often purposely) as tech startups but are actually some thing else. Uber, Lyft, Airbnb, Coursera, Udacity, Instacart, Juul, WeWork, and the like are to me, products from a different industry all the together. The tech aspect of their business does not influence their success as much as it may seem.
Not sure if you'll see this, but Steve, you've done wonders for the Rust community over the years. Rust would never be the language that it is today without your amazing work, so I (and I'm sure many others) are extremely grateful for all that you've done. Congratulations on this bittersweet milestone, and thanks again!

Ask HN: Is it OpenJ9 making my application slower on AMD EPYC 75xx vs. Skylake?
Recently we tested our java application on the new instance types of m5a on AWS which are cheaper and come with AMD EPYC 75xx. I was surprised by the difference in performance, our application throughput got 2x reduced compared to instances running Intel Xeon Skylake Gold 8000 (c5/m5).
But many benchmark websites shows in many tests that EPYC is much better than the Skylake. which makes me wonder, but what I see is even worse than Skylake old gen 6xxx (c4/m4).
We are using OpenJ9 JVM and we are wondering if OpenJ9 is somehow more optimized for Intel (nonsense maybe)
That's exactly what they did. In the past year or so they've migrated everybody from a custom DBA type arrangement to a self-serve DBaaS system. They've also turned over the keys for people to do their admin stuff in a self-serve way in the on-premises-hosted cloud. You can now spin up an onsite VM very easily and do your thing, without letting the precious-precious flow outside of Intel at any time to e.g. AWS, Azure etc. (Though if what you do is below a certain secrecy level, you can do that too.)

The downside is that for those applications that have tried to stay on the custom model (cough), IT service quality and quantity has gone straight down the shitter. You can submit help tickets and like never hear back. I guess now I know why - it wasn't so much "Thanks for coming, enjoy your stay" as it was "Run for the lifeboats, we're sinking the ship!"
> when people accidentally got separated from the space station, they were not forever lost?

Only if going perfectly sideways, i.e. keeping the same distance from the center of the gravity well ("and the tolerances are inhumanly small").

Go down, you'll spiral to the bottom; go up, you'll float away, maybe to the Sun or Jupiter or just the Ooort cloud and beyond.

(I don't think you'll find another stable orbit without some sort of maneuvering jets or very well tossed bits of spare mass you may have on you. Even so your distance from the station is probably unrecoverable.)

> Two of the primary reasons people buy Apple products are because of the ecosystem and their standard of quality. Now people are forced out of the Apple ecosystem and must buy a product from 3rd parties that don't have the same quality requirements.

This isn't the first time that Apple have decided that ecosystem didn't matter - some of the USB-C dongles (the Ethernet adapter for one) that Apple sell are branded Belkin, they ceded the Thunderbolt display to LG (that LG really Just Worked [1]) and they've abandoned Airport.
