chha··on What a deepfake video of Mark Zuckerberg reveals about how we're manipulated
How would this prevent anything? A deepfake is essentially video which has been edited. Most newsstories have also been edited, either by processing the sound, video or adding fx and graphics. How would you verify these edits against the ledger, and how would they differ from a deepfake?
chha··on Hiroshima (1946)
This was also considered before the bombs were dropped, and has been documented. Wikipedia has some information on it [1], with the short version being that it wasn't possible to stage a credible demonstration without making an actual attack.

chha··on Japanese Medical School Deducted Points from Exam Scores of Female Applicants
Kind of. Here in Norway the parents currently have around one year of paid leave, give or take. Out of this period, three weeks before and nine after the birth is for the mother, while the reminder is split threeways with one third dedicated to each of the parents while the last third can be used by either although not at the same time. The father also has one paid and one unpaid week during birth to help at home.

While there are some upper limits, parents usually get their full salary paid by their employer, who in turn get refunds from the government. There is a variation on this giving slightly more time off for less pay as well, plus some exceptions for single mothers, adoptions etc.

It's not a perfect system, and it's not created with the mother's career in mind, but it does accomplish some things:

-The father spends time with the newborn; if he chooses not to use his third of the parental leave it disappears. This leads to more involved fathers, and also help to even the score on who tends to the house.

-Parents can't be fired or refused employment for being pregnant. You also don't have to disclose this during interviews.

-Companies knows that having kids is natural, while smaller ones may struggle to find replacements during parental leave, the system is flexible enough to allow people to work a few days a week if they choose to. This is up to the parents to decide, employers can't dictate what they should do.

-Employers know that employees taking parental leave will come back, so any experience and work-related knowledge isn't lost just because they are having kids.

chha··on Some Amazon Reviews Are Too Good to Be Believed – They're Paid For
I generally avoid looking at good reviews when shopping due to this. Instead I assume that whatever doohickey I want to buy works as advertised, and look for reasons not to buy. Bad reviews are much more helpful in this regard, as they pinpoint weaknesses or other issues.
chha··on New Video of F-117s Flying Out of Tonopah Despite Their Fates Being Sealed
The numbering system was reset in 1962 as part of a bigger change, unifying aircraft designations across all the service branches. Some aircraft designated prior to this kept their designation, while others changed. Soviet aircraft obtained by the US for test and evaluation were often given designations >100 so they could be referenced internally without giving away what they really were, as the evaluation program was classified.

As for the F-117; fighters are generally regarded as sexier and more attractive than attack, bombers, cargo or other types. By calling it a fighter the USAF reckoned that recruitment would be easier and also that it's real purpose would be obfuscated. This is also the reason for the number; by giving a high number they indicated that this was an airplane designed prior to 1962 which never became anything.

chha··on Ask HN: I started a company in Japan but I'm in over my head
$50k is a lot for people in general, but not if you are starting a company. Especially one in another country with different laws, culture and language(s) to what you are used to.

chha··on America has a truck driver shortage
Or perhaps more likely; taxes are cut and companies see it either as a chance to lower their prices even more or have a bigger profit for a while
chha··on A Plane That Accidentally Circumnavigated the World (2014)
During ww2 thousands of new airports were built all over the world, including in very remote areas such as various pacific atolls where flying boats had been the only alternative pre-war. Once the war ended many of these became available for refueling stops, and as land-based aircraft often had a lower seat cost/distance as well as higher cruising speed they took over from flying boats.
chha··on How Sweden is building the world’s second-longest road tunnel
And even this will be outdone by a new one they just started building, which will be the longest and deepest. https://news.ycombinator.com/item?id=16560951
chha··on ReproducibleBuilds
Would something like this be possible for npm? Why/not?
chha··on The Peculiarly Quiet Decline and Fall of the KVM
This! I was a big user of KVMs for many years, but haven't used one for the past ten(ish) years after discovering Synergy. I don't switch monitor inputs, but have had a bunch of them connected to various computers, and being able to switch with no effort at all is great.
chha··on Trump’s DOJ tries to rebrand weakened encryption as “responsible encryption”
"We know from experience that the largest companies have the resources to do what is necessary to promote cybersecurity while protecting public safety. A major hardware provider, for example, reportedly maintains private keys that it can use to sign software updates for each of its devices. That would present a huge potential security problem, if those keys were to leak. But they do not leak, because the company knows how to protect what is important." (Quote from Rod Rosenstein in the article).

This kind of says it all, doesn't it? It's not a matter of if the keys from these large companies are exposed, just a matter of when, similar to what happened to Piriform earlier this year. If all such companies are to keep master keys which can decrypt communication going through their software they are likely to be an even bigger target.

According to Amnesty 119 out of 160 governments had restrictions on freedom of expression in 2014. I can think of several that are likely to be interested in being able to read whatever messages are being sent in order to target dissidents. Journalists are in many cases depending on privacy and security to be able to do their job. At the moment the US is ranked at 43 out of 180 for freedom of the press by Reporters without Borders; if Rosenstein gets his wish, what is the likelyhood that journalists will be among the first to be targeted?

There can be no middle road or "responsible encryption" as they describe it. The data is either encrypted with the recipient being the only one with the means to decrypt it, or it's not encrypted at all.

chha··on A Method for Web Security Policies
tl;dr: Public security.txt file to be used to instruct people how to handle security flaws.
chha··on Ask HN: Why is Linux not a mainstream OS?
Several reasons:

Perception: Linux has historically required tweaking and doesn't work straight out of the box. This requires computer skills, and the guts to actually make changes that might potentially break your installed system. For the mainstream, this is a turnoff. While things tend to work better today, the image persists; Linux is for geeks, and is too difficult for people with no interest in the computer itself.

Software: While tools such as wine, playonlinux, steam and similar alternatives make life easier for those who want windows-only applications in Linux, they are not perfect and rarely work out of the box, especially on new applications. While patches or workarounds tend to turn up, around half of the applications on appdb.winehq.org are rated silver or less, requiring tweaks to work, if at all. People want their things to work without any hassle, and aren't interested in spending time to learn how to configure wine or the rest of their system for it to work.

Hardware support: Although improving, drivers can still be a problem. Getting drivers from eg. Nvidia is fairly easy but installing them is not as easy as it is for Windows, unless you know how to add the Nvidia PPA (which requires knowledge, see above). AMD is supposedly worse, but I have still to buy a GPU from them. Getting drivers for other proprietary hardware can be a lot more difficult, depending on what it is. I've got a fairly common MB from MSI, but I still have to tweak the default Ubuntu config to get the sound to work. If it wasn't for the fact that I know how and prefer Linux over Windows, I'd just stick with Windows (where it just works).

Why bother: There is nothing Linux does so much better for most people that it's worth taking the time to switch. Most people I know (not counting colleagues) know virtually _nothing_ about their computers or how they work, let alone which version of Windows they run. I think most people are somewhat like that; the computer is a tool for them to do "stuff", as long as it works, they're happy. Or at least content. Switching to Linux doesn't help them in any way, but generally mean that they have to figure out how to get a lot of things working properly (which used to work just fine in Windows) and they have to struggle with howtos that might be outdated or just plain wrong for their situation.

A major selling point for many Linux advocates is that it's free and open source. But most people doesn't care; they might buy a new laptop every 3-5 years which comes with Windows pre-installed, along with a discount for Microsoft Office and a bunch of other stuff they think they need. So why bother having to learn something they don't see the benefit from?

chha··on Norway tightens IT security to prevent ballot tampering
There were similar reports earlier this year as well. Autopass, a Norwegian company responsible for most road tolls reported that a bunch of reports became publicly accessible as a result of people using Edge internally, and Evry reported the same regarding a bunch of invoices and other financial information from a client of theirs. (https://www.digi.no/artikler/16-mai-ble-det-full-krisebereds...)
chha··on Tinker, tailor, soldier, sandbagger: sometimes TV from the 70s holds up
I disagree. If you are making a show about wizards which will be aired on Netflix, you know that the target population are those interested in magic. Hence, you can create a more complex and detailed story/plot, characters, settings and so on, because you know that those watching are more interested than the general public.

They are also likely to be less forgiving if they expect a show about magic created by others also interested in magic. A show about magic aired on Discovery Channel on the other hand is likely to be superficial, lacking of deeper analysis or content, and laden with tons of repetition after every single ad break just to avoid confusing viewers with a three minute attention span.

chha··on Norway, where no salaries are secret
Many unions in Norway in the private sector (if not most) generate statistics based on information from their members regarding salary, education, experience and so on, so for me as a developer/sysop there really is no need to check what my colleagues are paid. I work at a place where everyone has a different background, so I don't expect the same pay for everyone. But I expect that I'm paid similar to others with the same responsibility, tasks, background, etc within the industry and geographical area.
chha··on NASA admits it doesn’t have the funding to land humans on Mars
But hasn't this generally been an issue since Apollo?

Great Ideas(TM) emerge and people get enthusiastic about them, but fail to realize that the cost makes them difficult to carry out as intended. The Great Idea is then either watered down (Skylab, Space Shuttle) or comes to an abrupt halt due to lack of funding or for political reasons (Space Station Freedom, Constellation).

I'm getting more and more convinced that it will take autocratic nations looking for prestige, or commercial companies offering cheap and exotic tourist flights for humans to get back to the moon. The US doesn't have the political strength or stability to plan such a mission at the moment, and keep it going for the ~10ish years it takes.

chha··on Battle for the Internet
Same in Norway as well. I can think of at least 5 ISPs offering at least 60Mb/s down, but there are probably smaller companies I haven't thought of.
chha··on Silicon Valley has a bad habit of “inventing” things that already exist
History is full of people who have been good at talking and presenting, but not as good when it comes to inventing. So I'm not that surprised that they get money, even if the ideas are somewhat pointless. I'd be more surprised if they ended up becoming successful.
chha··on Silicon Valley has a bad habit of “inventing” things that already exist
Although unlikely to be representative of SV, does anyone know of other examples than those mentioned?
chha··on What the Public Knows About Cybersecurity
Non-IT friends tend to see me as somewhat paranoid when they notice me using 2FA or VPN's, but I was actually surprised people knew this much.
chha··on If you publish Georgia's state laws, you'll get sued for copyright and lose
One would think that making laws and regulations easily accessible would be a priority for lawmakers. Is this issue exclusive to Georgia, or are there other states or nations with similar restrictions?
chha··on How to Clear a Path Through 60 Feet of Snow, Japanese Style
Also see https://www.youtube.com/watch?v=FPxAvHdrK6U for a nice video. Although not as much snow, there are still locations in Norway where you can find similar conditions.
chha··on Li-Ion Batt Inventor: New Tech for Fast-Charging Noncombustible Batteries
If this works out it will revolutionize the EV market more or less overnight. No manufacturer can continue using current batteries if this becomes a reality, an the recharge time is reduced to minutes.
chha··on Ask HN: What's the most expensive physical item that can be bought online?
Didn't spend a lot of time on this, but most expensive I could think of was this PoE card which could be yours for a measly $50.000 USD: https://www.amazon.com/NETWORKS-BlackDiamond-1000BASE-T-opti...
chha··on Playing with Toys While People Are Dying
Nothing new. During WW2 (and probably other wars) gambling houses, racetracks, pubs, hotels and many other similarly frivolous services had lots of traffic and customers. People simply needed to escape from reality every now and then and enjoy themselves.

Sure, we can do more to help the world. But if we're unable to live ourselves we can't do sh*t.

chha··on Immersed oil cooling for data-centres?
No intimate knowledge of this, but as with anything it's the economics that will decide if this is the next big thing or not. James Hamilton did a writeup on the economics of running a datacenter a few years back[1], and concluded that approximately 1/3 of the montly expenses are for power, distribution and cooling.

If immersive cooling doesn't significantly reduce the lifetime of components and doesn't add costs (additional mops?) enough to offset the reduction, there is no reason why it shouldn't be useful for most datacenters. Intel was working on this a few years back [2], and as far as I can tell the Cray 2 used immersive cooling for some components in the mid-80s.
