Kinda fun to see the increase in AMS-IX traffic: https://ams-ix.net/technical/statistics

Keep in mind this is only one of the many DE-CIX datacenters, they exist in at least 8 datacenters in Frankfurt: https://twitter.com/goebelmeier/status/983453047543214081

Only those peers who are single-homed to Interxion FRA5 / DE-CIX6 will have experienced an outage.
I know Uber initially formed a business partnership with JUMP a couple of months ago and I think they started analyzing the data and found a compelling reason (like user adoption, freq, stickiness, etc.) and found a business value to just own the platform.
Is there any possibility of getting a signed macOS package for this? I can't install anything on my work machine that's unidentified.
Only those peers who are single-homed to Interxion FRA5 / DE-CIX6 will have experienced an outage. The whole of DE-CIX isn't down.
thanks for linking this, I was looking for a way to intergrate slack into weechat without using the irc gateway since they are dropping support for that

That's the point. If we pass regulations that result in continued and increased centralization because only large organizations can afford compliance, that is not advantage to the people whose lives are at risk.

If you're a homosexual in Russia or a democracy activist in China or an advocate for womens' education in parts of the middle east or a Jew in WWII Germany, "privacy laws" can't save you. A company's fear of the state can't protect anyone from a corrupt state. But structural and technological privacy protections might. Which are the things hamfisted regulations inhibit.

5 minute delays are common on twitch, especially to circumvent stream snipers. Totally live video is a liability actually and I would guess most live broadcasts have a delay.

In any case, I wasn't referring to inter-frame parallelizability, I was referring to intra-frame parallelizability which doesn't require a delay.
A long time ago I bought a serial terminal and a whole bunch of serial cables from them. Along with a Cisco PIX. I still have all of that somewhere in my garage.
This period is only after the start of the job. (it did not seem clear from your comment)

Also I did not know the maximum duration of trial period has changed, thank for the info.
And the hordes clamoured in unison "You need to have an MVP. If you are not embarrassed by your first release, then you have released too late!!". And the developer released his Minimum Viable Product unto the public. And the hordes were dismayed, and they reeled back uttering "That is butt ugly!". And the developer was dejected and wandered away to work on something else.

In all seriousness - mixed messaging as seen on this thread is why I believe most (myself included) eschew the whole 'MVP' thing and try to polish products before release.
I can't even tell if you're kidding, to be honest. Disabled cars in and upon the public way are a daily sight in my town.

Same here. I only follow graphics programmers and game developers. The graphics people are ok, but a few of them tweet a lot of politics in addition to content I wouldn’t want to miss. And game development is thoroughly saturated in The Culture War, so there’s no practical way to avoid that except to ignore it.
I'd be very surprised if the water in Prague was consistently bad. One failure doesn't mean much in the big picture.

Edit: And it certainly isn't comparable to having water that's not safe to drink at all (bad water being the rule, rather than the exception).

I’ve heard that those positions do not treat laborers in ways to be modeled as success.

The best way to position a market is such that the parties involved naturally meet mutually beneficial outcomes. Ie incentivize away from abuses and toward goals.
Riding your bike to work was one of the only things that is the same in San Francisco no matter what socioeconomic class you're a part of. Jump changed that. Disappointing.

Everyone riding a bike used to deal with the same problems. Unfortunate as those problems are they could happen to a rich person, a poor person, or anyone in between which is an equitable sharing of the social cost. The privileged people used to be able to easily spend more money to replace a stolen bike which is the problem Jump solves for the people that can afford it. That's now a bigger burden on the people who can't afford Jump and are less likely to afford replacing a stolen bike at all.
I have been working on a video game with a puzzle mechanic involving mixing paint to create trails in a racetrack, and I have learned a lot about the intuition gaps in light/color physics theory while testing with people. I was going to make a post about it but this is an even more in-depth exploration of the whole thing from the bottom up.

I will be referencing this on our game site when it's up!

That's pretty much it! There obviously is loads of optimizations that can be done, but it obscures the pretty standard linear algebra that is used to represent and calculate the states of the quantum computer!

I was going to say driver's license. But I guess that's optional too. There are garbage fees or charges. Sometimes you must pay them, even if you contract with a private hauler. But you need that to get an occupancy permit. Also water/sewer fees. Unless you have a well and septic system.
I have to believe that some of this about brand awareness.

That’s some solid journalism right there. “Well, I googled it and didn’t see anything.”

Is Jump really that expensive? Last time I used it, it cost something like $2. It's cheaper even than the Ford bike shares.

Plus it can't get stolen.

I guess if you use it every day it does add up to a new cheapest walmart bike every 45 rides. Hmm.
Why not use wire then?

Possibly. But I wasn't talking about that. I was talking about the probabilities of accusations (true and false, respectively).
"If you're not part of the solution, there is good money to be made in prolonging the problem"
Love this idea. I would definitely be much more likely to give true feedback with this approach. To me, this highlights an interesting insight: I think people don't give 5 stars because they fear social judgement. They give 5 stars because most people don't know what a 5 star means, and they don't want to think about it. Asking concrete questions makes it so much more transparent. I am going to apply this suggestion to some other places as well. Thanks!

I've wondered - is it a common memory optimization tactic to store the individual qbit values until they become entangled and the product state cannot be factored? Or is entanglement common enough that it wouldn't be worth the overhead?
I've heard anecdotes of people who delete posts from Instagram if they don't get enough likes - some figures included a minimum of 100 likes. I can absolutely see where the mental health problems come into play from that.
Couldn't agree more. I tend to only follow my friends on Instagram (and not celebrities and other special-interest accounts), and it makes me happy to see them doing things that make them happy. Posts that have to do with politically charged or other negative issues are few and far between. Facebook is nearly the opposite of this for me.

It really baffles me how so many people don't realize that Instagram generally will only show the "ups" in a person's life, and often not the "downs", and actually allow that to make them feel bad about their own lives.

I guess at the end of the day I communicate via other channels with a lot of the people I follow, so I know that their life isn't as rosy as their Instagram feed alone might make it seem (though even if I didn't, that "insight" seems like a no-brainer). Perhaps a lot of people in the younger generation use things like Instagram as a primary means of catching up on what's going on in their friends' lives? And growing up with screens in their faces has changed how they react to things in some really bad ways?
I'm curious how you interpreted the very first sentence on the page:

What trials and tribulations did you picture that came with writing a single page application in an email client?
Then they shouldn't have blamed SpaceX.
I really wonder what the user experience would be like if only the creator of the post could see the "likes" on Instagram and Facebook. Similar to Snapchat, I think it would alleviate some of this anxiety and need for validation if we didn't see how much attention our friends get on social media.
Yep, even before I saw your comment I guessed that the initial SpaceX hit-piece was written by Andy Pasztor.
I admin some long distance DWDM systems... Cutting a cable and inserting a MEMS optical switch into a path would introduce a noticeable degradation in signal level on the Rx end. Not saying it isn't possible, or that they can't make it look like minor cable damage from being hit by an anchor. The far more likely scenario is that the NSA has per-circuit taps at major cable landing stations (New Jersey/New York area, in Cornwall, etc). The GCHQ has a huge facility very close to where a number of submarine cables land in Cornwall.

Trying to tap and store the data from every wavelength in a 80-channel DWDM system is like drinking from a firehose of data.
This aligns with my observation and current impulse. I've been extremely hesitant to do my own startup- imposter syndrome maybe, but more likely healthy skepticism about the odds for success.

Now that I'm in my mid-40s I'd be much more comfortable taking on the task. Wide life experience, learning to interact with and observe human tendencies, and learning to overcome internal and external obstacles seems like fertile ground for business success.
See how you had to qualify it as in your town?

This is illegal, and uncommon. Maybe you live in a rundown area with a poor rule of law, but the norm is a car in the road gets towed and it’s owner pays.

Are the share bikes getting “towed” and their owners billed?
Personal e-bikes for $1000-2000 (same experience as Jump) can easily be under $.25 per ride. I have 1000+ rides and 4500 miles on my $1800 ebike in under a year and I could sell it for $1400.
That was a pretty nice write up about it. I don't know very much about video encoding, and usually when I've tried reading about it I very quickly am out of my depth, but this bit seemed pretty reader friendly to a not-even-close-to-an-expert like myself. How did it read for those who actually know about video encoding?
I've only used Elm for a hobby project. Given how much I enjoyed the experience of web app programming for once, it's nice to read how well it scales to a large application.
Myanmar activists: Facebook’s plan to stop violent speech: ‘nowhere near enough’
Fun place, I remember getting hard-to-find power supplies around the end of the 80's for the robots I used to support.

I also remember a client who picked up computer parts that he had to machine/adapt to get to work together, back around 1993, I think. He lamented that they spent more time trying to get stuff to connect (physically and electronically) than actually learning about how computers work (the original intent of the class he took). I am not sure if it was his idea or the instructor's to get parts from WeirdStuff...

Hey Mate,
I've been into web development and ruby scripting as a hobbyist for 3 years now.

It has helped me significantly in my professional and personal life.

The best way to make meaningful contribution is to become a true beginner. It's hard work but will change your life. You will have an entirely new framework to pull on when thinking about problems.

I would start with something like Lambda School Machine Learning Free Mini Bootcamp and then let your natural curiosity take you from there.

Rock on and I hope you help the world become a little bit better.
Thanks for warning about compile times.
This is awesome. Over time I have came across too many posts claiming to explain QCs to hackers and they go on pages and pages without distilling this simple little thing. It would be great if you can also implement something like Shore's algo with your simulator.

How can an image properly illustrate (in RGB) what colors are outside of the RGB gamut? That image must be inaccurate? Should I assume the image is technically incorrect but a good illustration of what the RGB gamut does look like?
It depends! If you use a lot of scratch qubits, it can be useful to use sparse vectors, but if you are going to be doing a lot of superpositions / entangling many qubits, this isn't as effective, and performance suffers a lot. Libraries such as libquantum (written in C) use sparse state vectors, whereas the QCGPU library uses dense state vectors (as it is being stored on the GPU, it doesn't really impact the performance of the computer it's being simulated on). I benchmarked it, and the rust one was way faster for everything, apart from the initialization of registers and the application of some controlled gates
When I was in high school some circumstances led to a recommendation that I could drop out and start making money. I never for a nanosecond considered that as an option. Obviously that's not a perspective shared by all, and even those who wouldn't choose that may be facing a different reality than I did.
I've watched several of those, and they are good. Though for me, playing with code is a different type of learning than watching videos. I should go back and watch the one on ceval though.
Any business that doesn't do everything it (legally) can to minimize its tax burden is doing a disservice to its shareholders.

Follow the incentives - no individual or business knowingly pays more taxes than it is obligated to.
This is the very same concern cyber-security researchers face every time they notice a vulnerability. Do they publish their work openly and potentially leave all those using the service vulnerable to attack?

Yes, for a combination of two reasons:

1) They have obvious incentives to publish their results.
2) The more we know about vulnerabilities, the better we are at combatting ourselves against it.

That second reason is why we are (overall) better off from acknowledging possible threats to our existence. In your example, the more open the study of super-pandemics is, the more open the study of combatting against super-pandemics is. The more we are aware of a threat, the better informed we are to prevent it.

Yes, in your example, the threat could be highly dangerous and imminent. However, if only one individual was capable of creating a super-pandemic, the number of people who could potentially help stop it is drastically reduced. Rather than a free distribution of results which arms our society completely with the ability of preventing it.
I never enjoyed frontend programming until I came across Elm. Not only that Elm turned out to be a gateway drug to Haskell. Now I write frontend and mobile apps in Haskell using Functional Reactive programming (FRP).
(Author here.) That looks like a great library --- I will have to try it out!

In case it helps anyone, I also wrote a much smaller MDP library in ruby to support this 2048 project (and several others): https://github.com/jdleesmiller/finite_mdp . It basically just does value iteration and policy iteration.

After the constant invitations to check that poster’s comment history, I did, and you are correct in your assessment.

For example, they claim to have invented an AGI themselves. https://news.ycombinator.com/item?id=16461258

It’s unfortunate that in this field it’s possible to write so much before people realise.
Honestly, it took digging through multiple pages to figure out what (this) Elm was about. If you come in with a preconceived notion of what something is supposed to be about, and there is nothing which even gives a short blurb on project goals, it can be a little bewildering. Clearly it wasn't about the email client (that was a bit tongue-in-cheek), but I was curious about what the project actually was for, and had to really hunt to find any information.
Funny how they already support the AV1 encoding but neither the encoding is finished nor the hardware implementation is done.

I came to the valley (no, the other one, up north) back around 1995. And Weird Stuff was absolutely one of the things that made it "Silicon" valley.

Back when I would BBS from Kansas and pore over text files listing BBS's I was green with envy at all the boards in Sunnyvale, Mountain View....

Coming out here was everything I had imagined when I walked into Fry's, Weird Stuff, Disk Drive Depot, The Computer Literacy Bookstore, Haltek Electronics....

Slowly though the hardware Mecca that was the valley gave way to the internet titans and software as Yahoo, Google, etc. appeared.

Fry's started selling T.V.s mainly.

The Saturday morning electronics surplus crawl that used to include a half-dozen stops became just HSC....

Weird Stuff moved out near the Sunnyvale dump.

The pizza dive on Steven's Creek that Woz loved became Pizza and Noodles, then just Falafels.

Vivi's is gone.

When the Donut Wheel closes shop it will be time for me to move on.

To the effect of "nobody should be driving like that" - I have driven at walking pace at times, considering faster speed unsafe. I do agree that would be a better task for a SDV, iff it can full fill the promise of that marketing video.

I also agree that various conditions are suited to different sensor types - thus for an autonomous vehicle, multiple sensor types are needed.

This (and every other gamut picture in existence) can't, which is why the colors don't change any further outside the RGB triangle in these illustrations online. (In CMYK print it's even worse.) You have to use your imagination that the colors become even more intense.

A good parallel would be if you ever try to take a snapshot of a vivid sunset on your phone, then compare the screen image with the sunset behind you. The sunset's colors will be far more vivid, saturated, intense, than anything your phone can display. Those are some of the colors outside the RGB gamut.
Will be interesting to test this against Cyrus' two skiplist based databases:

https://github.com/cyrusimap/cyrus-imapd/blob/master/lib/cyr...

https://github.com/cyrusimap/cyrus-imapd/blob/master/lib/cyr...

They take slightly different tradeoffs. I wrote twoskip to work around a handful of issues with skiplist around crash recovery. The big cost still is repack speed, which is why I have a project to build something called zeroskip, which won't be single-file, but will have some very nice never-rewrite behaviour.

http://opera.brong.fastmail.fm/talks/twoskip/twoskip-yapc12.... describes the design of twoskip a bit.
