Long before HFT firms, we had Market Makers -- they were often a separate department of the brokerage firm you were already using.

Therefore, Markets don't need HFT firms to provide this service, they simply coopted a friendly-sounding rationale in an attempt to dismiss skeptics.
Indeed. My A7ii uses a very similar sensor to some Nikon cameras, and the sensor is literally always on, because the camera lacks an optical viewfinder. While the noise for very long exposures is negatively affected by the temperature of the sensor if left on too long without being allowed to cool down, the camera is made for having the sensor on for hours and hours every day without issue, and the Nikon sensors aren't any different.

Whats most likely to break, however, is the shutter mechanism. But even that isn't affected here.
> Slack are mostly trying to convert people who have never used instant messaging in the workplace to using it daily

Not sure it even goes that far. They're trying to convince corporate gatekeepers to adopt it, and 'more features' sells to them. The avg person in charge of deciding to use slack at a company is likely not going to care if memory usage impacts other stuff on the users' systems.

re: the google docs sharing thing - I really hate it, because I'm pretty much always asked this question, and I say 'no' or remove the alert, then I'm asked again next time. And the next time. And across every org i have to use slack for. Either use 'corp' or 'room' preferences for this, or remember and respect my own preferences. Quit asking something repeatedly.
> That's not actually reasonable, it's feasible for very specific contexts.

I was inventing a new hash function for myself, just for giggles a few weeks ago.

I needed a constant: I started by choosing an arbitrary constant (I started with 0x31415926...), but then I realized that the 32-bit space, and even 50+ bit spaces were feasible on my GPU.

I ended up rewriting the random-number generator on the GPU, and searched for the number which caused the largest number of "avalanche" bit-flips across the entire 32-bit seed space of the RNG.

Where an "avalanche" bit flip is 16 bits flipped, and 16-bits remaining the same, after the RNG was applied to the seed.

For example: seed = 1 * K, where K == 0xAAAAAAAA will cause 16-bit flips, and 16-bits to remain the same.

Repeat for all 32-bit values of seed, searching for the optimal K. 0xAAAAAAAA wasn't the best number (aka: 1010101010101010 binary), but you can see where my thought process was.

My RNG was more complicated than just a single multiply, but I think you can see where the general thought process was with my above example.

--------

There was a time when constants were arbitrarily chosen for these kinds of functions. But today, we can literally test ALL numbers and just pick the best.

If K is constrained by some other requirements (in my case: it must be odd, and a few other tidbits to work with my RNG), then you shrink the search space from 64-bits down to something that can be accomplished in just a few days of search.

-------------

As far as I'm concerned, the blog post is talking about how modern computers have conquered the 32-bit space.

My current post is how the 64-bit space could be feasibly explored. It wasn't even that long ago when 64-bit space was considered cryptographic-secure (see DES crypto algorithm or WEP).

Ah, so like Wikipedia they will launder their ideology through "credible news outlets".

"Don't blame us! A source with no proof and an axe to grind, told unverifiable gossip to an unaccountable journalist, who just happens to agree with us politically. But we're credible, so you're a racist now."

This is actually a good thing. Though the mainstream media has very little remaining credibility, Yelp will help eradicate the remaining shreds by further exposing the myth that media has built around itself; namely that they are unbiased, trustworthy purveyors of truth.
I'm gonna tag all Businesses as racist, I must be right cos I'm PoC. I'll probably hook it up with Yelps own POI API and write a script to tag Everything.

Throw in some other random dog-whistles while we're at it.
Ex-Amazon SDE here. The same happens in FAANGS: tons of software is written and served internally.

It's not NIH syndrome, usually. It's about having control over the whole software supply chain for security, reliability, licensing compliance and general quality.

I feel you. Very much in the same boat. I do miss a lot of the fun things I did on/with Windows, but with all the malware that's baked into Windows 10 (and prior versions too - they just weren't as heavily scrutinized it seemed) it's just a non-starter for me. Creeps me out too much.

A Microsoft Linux would also be DOA for me, given that I wouldn't trust it to not be the same as their current offering - jam-packed full of privacy-violating spyware, riddled with secret security holes, and getting worse as the days go by. At least with Debian and Fedora, I know what to expect, and I could have an influence on what happens there.

Cynicism aside, I do believe that Microsoft's Linux would be a great choice for consumers. Background upgrades with fast reboots is my number one selling point of Ubuntu to regular users.

Write an email to your reps. All of them are listed here:

Their staffers will respond with a nice form letter, but if you identify yourself as a constituent with specific professional knowledge and a suggestion like this about current hearings, stuff can happen.
That would be a little difficult to pull off at the municipal level. The federal government doesn't even fully implement that strategy, which is why we are unlikely to ever see systemic fixes for consumer data protection at the Federal level (that doesn't involve barriers to entry that favor established industry).
Hah! I didn't even bother to check, I'm so used to just going for the arxiv version when not on campus. (Usually has better formatting too.)

But the point is, we have built nuclear at scale. And built it at scale. France has over 70% of its electricity coming from nuclear, Belgium over 50%. The US is at ~10%. We've encountered the emergent issues, and fixed them. Cost estimates on nuclear are historical estimates. They're not projections.

We haven't built energy storage at anywhere close to the required levels of scale. We have 4 minutes worth of energy storage. Most of that is from hydro electric storage. 1% and 3% are from battery and thermal storage, respectively [1].

What will be the cost of scaling this up to the hours or days required to make intermittent sources viable? We can only offer cost projections: what we think massive grid-scale projects will cost. But cost projections do not include the costs of unknown engineering challenges. Remember, early nuclear proponents claimed it would be an order of magnitude cheaper than fossil fuels and had the studies to prove it. But real-world experience demonstrated otherwise. What makes us think that increasing our amount of energy storage by 2 or 3 orders of magnitude won't encounter similar unforeseen costs?

We have built nuclear at scale, and yes we have discovered engineering challenges that increase cost. But we haven't built energy storage at scale, and we haven't encountered it's unforeseen engineering challenges.

This post offers an excellent analogy on this topic [2]. With nuclear, we've walked this path, and know firsthand the difficulties it takes. With new technologies we're looking at the map. Those are two fundamentally different measurements of cost.

Would you please stop posting flamewar-style comments to HN? We're trying for something else here.

Also, could you please stop creating accounts for every few comments you post? We ban accounts that do that. This is in the site guidelines: https://news.ycombinator.com/newsguidelines.html.

You needn't use your real name, of course, but for HN to be a community, users need some identity for other users to relate to. Otherwise we may as well have no usernames and no community, and that would be a different kind of forum. https://hn.algolia.com/?sort=byDate&dateRange=all&type=comme...
Regarding point 2. That's totally valid if they come out and say why it matters. But they totally fail to connect those dots making it unclear if they are making that point or not.
The idea of open sourcing Colors and Fonts is tempting me. Opinions?
Hello everyone!
Well, is not like I have done any open source before or something but it feels a like an interesting idea.

The idea would be redesign the whole thing and removing parts of it, like the resources pages and only make colors and fonts tools, with great features.

Is it worth it?

There is from 300 to 500 users daily.

Thank you!
Chrome would need to pay Google an extraordinary amount to continue to be the default browser on Android.

Would they need to pay Google or would they need to pay Samsung? While we're breaking things up, maybe Android should not mandate any default browser.
Does anyone remember Social Autopsy? Yelp just found it's Business model.
I live in Portland. I march and exercise my Constitutionally-guaranteed right to peaceably assemble. On many occasions, Federal agents and police have preemptively declared peaceful gatherings "riots" and deployed riot-control agents and less-than-lethal munitions unprovoked. In others, they have not waited to declare such or order the crowd to disperse, and deployed tear gas and shot into the crowd anyway. Contrary to what Fox News is telling you, rioting is far from regular and I have yet to witness actual law-breaking beyond resisting arrest or disobeying law enforcement. The DA is dropping 70% of protest-related arrests because they don't involve violence or property damage.

So I hope you can understand how little trust I hold in the police to make sure the suspect they caught on camera actually committed a crime. Consider a gray space in the middle where the system of policing we have needs reform before we can trust police with tools that make them more effective at acting against the communities they serve. Police should have been protecting protestors and their rights, but they have been antagonistic and violent from the start.
Tl;dr: "If exchange clocks are imprecise--say they are only accurate to one second--and a HFT can execute many orders in a second, then the exchange could reorder all the trades in the second in any way they want, without being detected by an auditor!"

This is the only sentence in the article relevant to the title. Auditors need to insist on good timekeeping to prevent exchanges from committing fraud.

HFT firms don't fundamentally care about having accurate clocks. They care about reacting first. Having good clocks is useful for second order reasons like debugging and regulatory compliance.
Their site is somewhat explicit about it?

It may be helpful, then, to draw a distinction between propaganda targeted at a domestic audience and propaganda targeted at foreign audiences.

I think many would say that the US government shouldn't try to spread any "good ideas" that differ from what its citizens already believe are good ideas. That would still allow the US government to publish those ideas to other countries, though.
The only thing I miss are the resolutions. 15 years ago I had a Sony Trinitron running at *XGA. Today most monitors are still HD. And even most 4k monitors are in fact sharper HD displays.
Depends on where you are but in most of Europe winters are pretty okay. I've never owned a car and used a bike for all my life and the few days where it's actually icy or snowy (Germany in my case) you just switch to public transport. And if anything it seems like the winters keep getting milder.
Some would argue Soleimani escalated by coordinating attacks on the US embassy and military bases.

And hopefully, Iran doesn't decide to shoot down a commercial airliner half-filled with their own nationals, that took off from their own airport, as retribution for these domain name seizures.
I have one question for all the articles that write, rightly so, about how efficient nuclear is. Can you guarantee that another Dyatlov won’t be put in charge of the plant and potentially cause massive devastation?
I wouldn't make a bet based on it, but it's possible.

Kernel engineering is challenging, precise and experience-based work and it's tricky to recruit and develop for those talents when your codebase is proprietary.

A large number of companies depend on Linux, and that creates a common interest in multiple areas - reliability, architecture support, security, and so on.

Under this suggestion, "Windows" as you experience it as a user might not change very much - but within the software stack, Linux would replace the existing proprietary kernel.
This is the way of the world. How much cpu and gpu advancement is directly attributable to the simulation of shooting each other in the face?
No, -0.f is more interesting than 4.1045857301e23f. It's more interesting because it's more likely to fail a test where others don't.
Because there is no clear line between saving and not saving. It's just degrees of badness the longer we wait. I heard there are some inflection points when it becomes warm enough for methane to escape from the tundra in Siberia.

You can also truncate hash at 30 bits and use it to address bucket, 12gb then would give you like 3x32 bits, which you can store your candidates. Then compare full hash with candidates.
If we think that is a possibility then I'd say we have bigger problems with government power, democracy and voting in general. And instead of using "privacy" as a proxy for those concerns, we should rather address the actual issue and concerns we have with the power we give to individuals without accountability and oversight.

Like why isn't the debate here revolving around the suggestion that we need to have processes, and super-secure, open and cryptographically secure audit of all government actions so that government "privacy" violations are immediately caught and addressed? Instead, we're asking government to solve some arbitrary problem called "privacy" because we think it'll prevent potential government abuse in the future?
I had opposite experience. I always tender to take things seriously and felt like doing them just bit is wrong or weak and "unserious".

Result was that I stopped those activities soon, because they were draining. Meanwhile, people who just unseriously dabbled in them, tender to learn and get habits. They were not drained by them and had fun.
There's a difference between being anti-technology and being anti-one-specific-application-of-a-technology.

Analogously, saying "hey maybe cops shouldn't shoot citizens to death" is not a fundamentally anti-gun stance. For example, the Black Panther Party famously had patrols, armed with long guns, who directly challenged police brutality.
I honestly have no idea what you're talking about. Agree to disagree :)

Edit: actually I went back and read your comment again and I misread the second part of your comment to indicate that I didn't understand something. I get what you mean, but I think tail risk can get ignored a bit more when you're quantifying risk, because it is very difficult to quantify.
>these characteristics are enshrined in our culture and power structures every step of the way.
In a way, yes. Because sex is the largest difference between human beings. Its importance is highlighted by doctors needing to know for better treatment, for social circles not being comfortable around people further away from your group. Bathrooms being a painpoint as it has deep roots in culture and history. Though the interesting thing about which bathroom to go to, it becomes irrelivant the moment you enter someone's home; there is only one or two to choose from and they are "Gender neutral" by design.

>Will you be fired for wearing a dress when your boss sees you as a man?
This is exactly my point, discrimination based on immutable characteristics is wrong. if your boss fires you because you're a man or sees you as a man, or makes judgements because you're a woman pretending to be a man is wrong by design because it is still based on immutable characterstics. Though dress code violation is such a grey area as it is not directly based on strong legal precedent.

>If you are forced to put your biological sex on the application form, what if your new workplace outs you as "a man"
"IF" you are forced to do so. I've never seen it be mandatory. unless you talk about exeptions to the rule. Like how some women's shelters only hire women. or gynecologists.

>will they ostracize you, call the police, or exact violence on you because you don't fit in their worldview of acceptable behavior?
Nonetheless, anti-discrimination laws aren't there to stop discrimination or stop people from breaking the law. They are there to put them on trial. Lots of people fall out of a certain worldview and have lost jobs and friends because of that. talk to any clean heroin addict and they'll tell you. These things certainly matter and should be discussed as you are so kind to do.

I guess my approach is more conservative when it comes to enacting change in how people are treating each other. I consider no solution better than a bad solution. as no solution at least lets people have the freedom to treat eachother with the respect that they might deserve.
This depends on relative numbers and local culture; if there's not many cyclists and drivers behave aggressively or recklessly towards them, cycle lanes encourage people to try it in comparative safety.
Looks like the honeymoon is still ongoing.
I recall being regularly surprised how infrequently CDNd JavaScript libraries were cached locally. In my testing, even something popular like jQuery or Bootstrap has enough different versions and CDN hosts that it wouldn’t be cached ~50% of the time.

Perhaps what’s really needed is some kind of browser based package versioning and management system? Where your CDNs jQuery 1.10 is seen as a mirror of mine, with perhaps even some signing and authority of libraries not directly hosted on the host server? (I’m probably talking about something that already exists or has been discussed I’m sure...)
Americans typically assume I'm from somewhere in the Midwest but can't quite place where, and when I say I'm not
American they assume I'm Canadian. It's usually a bit of back and forth before they believe that I'm actually Swedish, and sometimes I have to bust out the börk börk as proof – it's a lot of fun! :o)
It's not exactly what you're asking for, but a few years ago I started creating a new playlist at the start of each month, naming it "<Month> <Year>", and I add any songs I'm enjoying that month.. Most of them come from Discover Weekly or Release Radar, but sometimes for other sources.

It's an easy and interesting way to go back in time and see what I was listening to etc..

I have a "house rule" where I never remove any songs from them after the fact. If I added it, then it stays.

At the end of the year, I try to pick 2 songs from each month to make a curated "Best of <Year>" and then compare that to the algorithmic one that Spotify sends me.

Anyways, it's been a really fun thing and a reasonable substitute for DW/RR archives.
It's also a sloppy way to put it. $300M is a fixed amount and should really be compared with the rate of profit resulting from this integrated over how long it lasts. It's a question of stocks and flows. An "edge" which is there every day (for a while) results in a rate of profit, not a fixed sum.

> For instance here in Finland companies that invested in nuclear made good profit, because of not having to pay costs related to carbon offsets. Politicians saw the profits, considered them "windfall" and taxed them away.

Can you please expand on this a bit? Did they the change the law to tax something that was previously un-taxed? Did they tax it at an effective 100% rate so all the benefit would go to the state and none to the investors, or did the investors benefit too?
Yeah, here in Denver there has been a huge amount of novel cyclists. Lots of old bikes dug out of storage and brand new bikes with slightly wobbly riders. Also, more diverse riders. I think it's great.

There's also a big increase in poorly maintained bikes- a squeaking chain is not just wearing itself out faster than usual, but also wearing out expensive drivetrain parts. Lubricate and clean your chains (and WD-40 is not lube)!
Sorry for hijacking GraphHopper's thread, but: you might want to try the OsmAnd phone app—it has some settings for routes in this very vein. E.g. ‘no unpaved roads’ and such. Not sure if it would solve your specific case, and OsmAnd isn't completely free, but it's an option (specifically map updates are limited for free, at least in the Play Store version).
How could a policy exist to counter this? Ban fingerprinting as a whole? The CDN actually has to know very little, right?
In Portland the District Attorney actually has a policy to not punish people breaking the law in protests.

So the surveillance video isn't going to matter for protests anyway.
Nuclear would be utterly terrible for filling in the last part of a renewable-dominated grid. As in, ludicrously expensive, compared to other non-nuclear, non-fossil alternatives.

The article you point to talks about "firm, low carbon sources". This kind of source for this last bit would be something like hydrogen, not nuclear. A nuclear reactor operating at 10% capacity factor to "fill in" for renewables would be producing power at $1/kWh or more, which is uncompetitive vs. hydrogen by a massive margin.
I live here and would generally agree with your assessment.

You bring up a good point about dealing with local issues. This movement is centered around a municipal budget concern, which is diverting funds from the police department to other forms of emergency response and community support programs. That our city is now the poster-child of the Trump campaign is telling.
> you can have both

Not if the Green New Deal sucks up all the resources for "renewables" that will never provide anything close to the base load power we need.
I find Rust really difficult to get into :( Python, you're right has a bunch of problems with datetime and packages, etc. but when it comes to productivity, it is insane how amazing Python is. Also being able to hack internals of python library and "batteries included" philosophy is why it is the most popular language in the world now overtaking Java.

There’s a simple solution to this, and that is to only allow playlist-level API access where the playlist author matches the account making the request. Users can transfer out any playlists they created, while Spotify keeps Rap Caviar or whatever exclusive to the service.
