This is going to be a tough sell.

$150 dollars is very expensive for a portable game system, which will compete with any tablet/phone that can play games that have better graphics and game play.

The problem is that this is competing with entire ecosystems of games that have been around for almost a decade.

That would only work if climate change deniers weren’t in charge of governments.

If the latest Australian elections are anything to go by, popular (popularist) voter sentiment is swinging towards denial.
Equality is not the only way in which the pseudo-communist Eastern Bloc differed from the West.
In an era of ultra-low unemployment rates, I don't see who this is protecting. If anything it's hurting US businesses by denying willing workers.
Unless it's specified to be 120k hard cash, it would turn into 120k total compensation including company accommodation worth 60k/year, various practically-not-claimable options, or others ways.
Not that I am defending this incident, but this headline is almost certainly a wild exaggeration.

From the article: "The flight landed safely a short time later, and the pilot was placed on medical leave, which is routine in such cases."

(Emphasis mine.)

Unless the laser-wilder is using something ungodly powerful, the pilot would have to stare into the beam and consciously override his blink reflex before damage could occur. It seems unlikely that you could even keep the laser focused on the cockpit for that long, at the speed planes move.

> "How do I undo a commit?" isn't something obvious like "git undo". Instead, it's the more cryptic "git reset HEAD~"[1]

The issue with this example is that `git reset HEAD~` doesn't undo anything, and it doesn't undo _any_ commit, just the last one. It will also cause push and merge conflicts if the commit you're "undoing" was public, which may end up with you not really having "undoing" anything at all.

It's also not anymore cryptic than any other industry's jargon. It's a sentence that means something specific. It's somewhat, but not entirely, what someone _could_ mean when they say "undo a commit".
Totally agree about Windows GUI's and Unix CLI's. Sprinkle some MacOS on there and you have my vision for Serenity.

All the fonts are hand-bitmapped by me, using the included FontEditor application. I was trying to construct the imaginary love-child of Tahoma and Fixed, so you are definitely on the right track there.
I love the retro look and feel, would be cool to have something like this as a theme or window manager for (modern) linux.

We've known about the greenhouse effect and it's threat potential for nearly 2 centuries. Exxon just helped add to a growing body of evidence that we ignore.

> Just because people have different values does not mean we don't share values, and more importantly, that we don't share reality. The things that I am intolerant toward are a disregard for the facts, a disregard for demonstrated relevance, and a disregard for the legitimacy of expertise and aggregate authority.

We may share the same physical reality, but many facets of reality that are critical to human experience may not be shared. In particular, and I am aware that this contradicts what you've just said, values seem to be very different across cultural boundaries. There are some general shared values that are often shared across cultures, but these shared values are also not the values that people care most about on a day-to-day basis. (Not too many people out there protesting murder, theft, etc in any organized sense.)

The values that people seem to care most about are the ones that distinguish them from other tribes. These values are often more important to people than basic needs. People will starve themselves over values, they will kill themselves over values. You can say they shouldn't. Obviously they disagree!

> I mean, if you're saying that this conflict is an integral part of human nature, then you're not asking me to change my mind; you're giving me a justification for why I don't have to.

It is an integral part of human nature. I'm not sure it can be "solved" without creating a truly oppressive superstate and permanently reducing human genetic diversity. Conflict is inherent to being alive; the best you can do is keep it on a slow boil.
Anything to deter H1B is great in my book. I'm sick of these guys coming over here and taking our jobs when we're perfectly capable of doing it ourselves for the same pay. It's time companies stopped skimming and started paying American workers
How much choice do you really have if literally all of your choices are from China?
Interesting timing, considering all the subpoenas they are supposed to reply to.
"The wrong reflection" doesn't give the right impression. The point a 100W laser projects against e.g. a wall, when viewed at 1m distance, can damage your eye. Even if perfectly diffuse. Even if invisible.

I recommend taking a laser safety training class. At least the ones focusing mostly on show lasers are widely available to the general public, and not expensive. It'll cover the optical dangers at least. Possibly it'll also build some respect for lasers, and maybe make certain things legal for you (important esp. after something goes wrong).

For machining lasers, there's a bunch of extra dangers to you _and_ the machine (e.g. particle exhaust, fumes, certain materials, fire risk (and secondary risk when putting it out!), very high voltages, human errors (I'm serious! and incl. both you and other/untrained people), legal requirements, overheating, electronical failures of the controller or interlock or (very relevant for hobbyists) plain bugs).

On the upside, hobby CNC lasers are often in the order of 100W (appropriate for cutting plastic/wood, engraving glass, and marking metal (with marking spray)), and CO2-based (10μm). A small stone brick will easily work as a beamdump. Basically _any_ thin plastic sheet will easily block secondary beams at this wavelength (so counter-intuitively the laser being invisible is an advantage!). And if the laser is dispersed enough possibly even direct hits, for a very short amount of time (up to seconds). (This is no excuse to save on the goggles.)

Do not trust cheap "complete, in a safe box" CNC lasers bought on the internet. They work, but require _extensive_ rebuilding to be safe.

It's possible and fun to work with lasers as a hobby. But please stay safe! If you can, don't go alone, find a fablab or hackerspace, maybe even build it there.
I feel like there are clearly ways in which facial recognition can improve a lot of systems -- ticketing (think airports, sporting events, concerts etc); automated stores (like the amazon cashierless stores); payment (imagine not needing a wallet because the combination of your face, gait, and voice is enough to verify you); security (home/building/car entry, detecting suspicious individuals, known terrorists, past offenders, restraining orders)

There are also the many valid awful ways it which it can be used, particularly by the government. Why not just ask for laws preventing the bad uses? I don't get why it has to be all or nothing. If it's strictly government use that is concerning, or police use, then pass laws banning government collection of facial recognition models. There's no need to pass laws banning all forms of racial recognition simply because there are certain dangerous use cases.

It'd be like if back in the 20's or 30's someone said we need to ban cars because they could someday be driven by terrorists into large groups of people. It's a tragically valid concern, but we all agree it's not reason enough to ban cars altogether. An even more realistic example is folks back in the day complaining about how dangerous cars were, and rather than banning all cars deciding on speed limits and safety belts and airbags and anti-lock brakes and so on. It doesn't have to be all or nothing.
I believe this is rumored to change soon (particularly on larger iPads).
Not entirely. China isn't imperialistic in the same fashion as Russia. That said there are parallels in terms of power dynamics within ASEAN certainly when compared with the Caucasus.
Boot up an old Linux distro from around 2001 and compare WindowMaker, AfterStep, Fluxbox, KDE, Gnome, Enlightenment, and half a dozen others. Compare those to fictional UIs seen in movies, Hypercard, visual development systems like the ancient Klik n Play or modern Scratch or MaxMSP, etc. Learn about OLE (object linking and embedding) and document-centric vs. app-centric computing. Think about all the different ways data can flow between components of a system and how those flows can be grouped differently. Look at alt and historic OSes like Be, TempleOS, SunOS, IRIX, DOS, VMS, OS/2, old UIs like Dosshell, Commander. Look at tablets vs phones vs desktops vs. game consoles vs appliances. Remember that bytes and bits and addresses and instructions and files and programs don't necessarily have to be the fundamental units of an OS.

Then, after all that, come back and tell us that a modern desktop is the utilitarian endgame of OS innovation :).
Internet of Things and the Modern Web
Viewing Terraform solely through the lens of cloud automation and in comparison with CloudFormation is a shortsighted mistake. Terraform has providers for plenty of other services that don't qualify as "cloud things" and lack proper configuration of their own. In a very general sense, Terraform is a terrific resource management tool with state versioning & locking built in. For example, there's a terraform-kafka-provider[1], which can be used to manage topics in a Kafka cluster. Could shell scripts be written to accomplish the same goal? Of course. Would those scripts inevitably develop in a haphazard, organic way to form a buggy and incomplete implementation of something like Terraform? You bet!

"Cloud" configuration may have been Terraform's proverbial toe in water, but the truly untapped potential lies in the other providers. Anything that can be packaged as a Terraform provider exposing resource abstractions can be easily managed using convenient HCL syntax. This, IMHO, is the unfortunately buried lede.

I agree. I actually think my instructors were excellent. I had a mental block that needed clearing. My EE instructors went out of their way to spend as much time in office hours as needed to students that needed it. I remember spending several hours in one instructors office trying to figure out where I was going wrong. She was also confused because all of my intermediate work was correct, but I always came up with the wrong answer. Short of it was that I was entering numbers in as reciprocals of what they should have been. E.g. I was entering 1000 in my calculator instead of 1/1000. Took 2 sets of eyes and a couple of hours to spot the problem. Went from barely getting a C at midterms to not losing a point the rest of the semester. Finished with a solid B amd the next semester was perfect. Only ended up there because of my instructor's help and accessibility.
For now at least.
OLPC would have needed a lot more power than this device, plus due to its small size the whole thing could be machined aluminium.

Especially if there's games that utilise the mechanic. could just have a much lower torque (and therefore lower-current-generation) since it's going to be used a lot. Missed opportunity.
Unsurprisingly given the proximity, Vietnam is just as bad in this respect. It is crazy, anything to make some money.
This is what happens when you indict foreign intelligence officers. You expose your own to criminal charges and Interpol Red Notices. It's just a question of time before US soldiers and sailors are included in the loop.
You've misunderstood. The "dstat" package was removed from Fedora, rather than have its contents replaced. The package containing the new program is called "pcp-dstat", so they already did everything you think they should have done.
The law would have to specifically carve in consideration of in-kind benefits for that to happen, and I see no reason to do so. Why would it?
It does not. Known issue with the rendering engine that Code uses. I was disappointed too. Apparently a fix is coming at some point.

How thin of softwoods are you cutting? Event consumer-grade products like Glowforge are 40W, so I have a hard time believing a 5W laser is practical for much. (FWIW I maintained a 65W CO2 laser cutter for a while.)
Why would the world even trust a Chinese company, backed by Chinese government, which has aggressive ambitions on the world stage, is politically fragile, authoritarian and routinely abuses basic human rights.

I mean, it's not just phones, Huawei deals in telecommunications equipment, has contracts with many European governments etc.
I'm sure it's a fun challenge for the game designers with the limited screen, and a crank mechanic.

But I'm really hoping they are also able to make some games with some depth and replay value to them for the players, a la the early mario, spyro, sonic or pokemon games.
> the general public can just refuse to participate

The general public will be misled by the media. Already politicians are claiming that the media isn't truly independent or objective with claims of "fake news". If the media falsely claim that you are a dangerous criminal, the public will eat it up and ask for dessert.
It's an opinionated piece of hardware, designed and manufactured more or less uncompromisingly for a specific musician experience.

> maybe humanity would have started acting 30 years earlier.

I wouldn't bet on it. We know we can cut emissions today by investing in nuclear ... and nothing. We could have invested in nuclear power 30 years ago and prevented trillions of tons of CO2 from being emitted.

Instead we decided wind/solar/natural gas (and those are always package deal) is our best bet at fighting climate change.

>For example, we can't keep having irrational leaders that ignore basic scientific facts.

Facts like nuclear power is by far the best and only way to effectively fight climate change?

The current "prevailing wage determination" includes fringe benefits already. There's definitely a way to play with those to redirect it back to the company.
The Idea Factory was excellent and really delves into the nuance of topics many of us see as black and white (government regulation vs. laissez-faire capitalism, monopolies vs. competition, pure vs. applied research)

The author also does a great job at making his subjects come alive. You really get a feel for the great minds of years past who have often stumbled in the dark before coming up with brilliant theories that we all still rely on.

No, compressed texture formats are lossy. Also the fixed bitrate that allows random access into the compressed pixels constrains the encoder a little more than the variable bitrate of JPEG or other image formats.
Simpler is to return production to countries that have proper environmental regulations. Right now we outsource pollution production to China.

Here’s a story: landed in Schipol (AMS) from Berlin with a good friend of mine. Jumped on a train and was half asleep when the train rolled in to the station just before Amsterdam proper. I forget the name.

Just as he train was about to pull off, a man approached us and said something incoherent in Dutch. Before we could even utter our confusion, he grabbed the backpack on my lap and ran for the doors. I followed him but not nearly as fast as I would like. He was jammed between the automatic doors and I caught a glimpse of him yanking himself onto the platform, where he stumbled and started sprinting.

My cries alerted other passengers who immediately pulled the emergency break. The doors opened and we went into hot pursuit.

Sadly, we never did catch the man that day. The backpack had my laptop and many important documents, but by the grace of some Unknown or my own laziness my passport was still in my pocket. In fact when we got to the police station I thought it was in the bag, and their attitude there visibly changed when I was able to produce it. They took a statement and that was that.

So the emergency brake is useful in some situations...never did get that bag back though ;)
Ask HN: How to get funding for a stealth startup
How to get funding for a stealth startup if some of the investors youre going after have already funded your competitor, and your startup has valuable IP that if gets in the hands of the competitors is total failure for your startup? As far as I know investors dont sign NDAs, but even if they do it would be really hard to prove they leaked info right?
We found a compromise in our city where plane spotters register with the local police and can be in certain areas outside the airport boundaries.

The program labels itself an "Airport Watch" like a community watch but, really, it's just so everyone is less suspicious of each other. But I suppose if we actually saw something odd we would phone it in between swapping our lenses.
Thanks for bringing this up, what were they thinking?
I thought at first that was the only reason to have the crank.
The goal is basically open. I would like to make this system good enough that I can spend most of my time on it. Without losing track of the original ideas.

A package manager is definitely coming sooner or later. There's actually an SDL port in the works (done by a stellar contributor, not myself.) I suspect that we're gonna need some sort of ports system in the Serenity tree to be able to maintain it. :)
This isn't meant to compete or be "the best". I think your comment is entirely missing the point of what this is.

This is more of a play on nostalgia and classic bulky simple handhelds. It would be in the same category as the NES Classic Edition or the Sega Genesis Mini. It's fun and almost a collectible honestly.
This is morally and ethically wrong. If the H4 visa holder has the right to work in the past then you can't revoke it. Those already working should be grandfathered in.
this only make sense if we also remove 'is he stealing american job' verification step (LCA) for h1b.
otherwise its just weird to do you bunch of checks for h1 candidate and not do any checks for the spouse when they are potentially doing the same job. If someone is working on h4 then they should be able to get own h1b otherwise they are "stealing an american job" by definition.
The best is Frankfurt, where you can actually go out onto the roof of the terminal without needing a ticket. It costs a small fee and you need to pass through a metal detector, but it beats sitting in a parking lot trying to get a view of the traffic.
Back in the mid 2000s at IMVU, I went deep on reading about E, EROS, Polyphonic C#, and Comega, which lined directly up with the problems we were having with asynchronous programming on the client.

Thus, I can point directly to E and friends as leading us to make such a successful, _correct_, asynchronous task engine.

It's funny to think about now. Promises and coroutines and promise pipelining and async are now well-explored, but at the time there wasn't much prior art to draw from, and everyone was figuring it out as they went. Do you synchronously block on futures? Should .then calls run on the calling thread if data was already available? How does cancellation work?

Once you have answers to those questions, you reach the higher-level ones: how do you structure your program so that asynchronous components can communicate? How do you unit test these interactions? What abstractions avoid needing to unit test every possible sequence of events?

We did a pretty good job and I feel blessed that we stumbled upon the E papers, leading us to create abstractions that stood the test of time.

Thanks Mark!
I would quibble with your basic premise of facial recognition improving these things or even if these things are worthy goals. At least from my personal and selfish interest I don't perceive any improvement offered for myself or society. From a perspective of a shareholder/interested-party looking to maximize X via Z then yeah it makes sense.
What's the deal with being tied to bower as the package manager?
If being married would double your chances of being picked then that would just lead to a bunch of people getting married to get a H-1B.

Goals there were different.

Nationalizing those industries and using tariffs to stabilize at a higher price would accelerate adoption of better technology. You could implode demand for natural gas and fuel oil by raising prices and capturing profits to capitalize heat pump adoption in the northeast, for example.
It folds into the side. That's why there's a hole.
Really, moving a supplychain is easier than punitive tariffs/sanctions?
