I mostly started this to do a fun little prototype in an evening, but now I'm a bit excited about it and might add new features over time.

This just grew out of frustration that I couldn't find a simple CLI tool to view .csv files in a sane way.

When I grew up and my parents got their first 386 PC, my dad would always have Lotus 1-2-3 open while I would stare over his shoulder. I was 7 years old and completely obsessed about computers no matter how boring the task. So this is dedicated to him. Thanks for sparking the flame.
That doesn't take into consideration of flaky home-routers (note that they do recalculate the checksum). So the checksum might be processed on bad data.

For a bad connection it will also be quite common that the checksum will happen to be valid. TCP/UDP checksums are quite bad.
The codes have palettes embedded to adjust to different lighting and ink.
No, but if you have non-locality, then you don’t need the non-definiteness of Copenhagen, and could do with something like a Bohm or MW interpretation.
<off-topic:> Cool username btw, huge Kerouac fan. I'm also from Lowell.
Okay, so walk me through how to do this in a dockerfile?

My first line becomes:

FROM debian@sha256:14e15b63bf3c26dac4f6e782dbb4c9877fb88d7d5978d202cb64065b1e01a88b

Okay, that's easy.

Now, what about older versions of packages in debian's apt repos that have been deleted? How do I get those?

I run my own apt mirror I guess which I update in lock-step with my dockerfile and thus don't let the Dockerfile reach out to the network.

Is this any different from what you do in a shell script on a server? You use btrfs/zfs/whatever to snapshot the initial version and back it up, you run an apt repository so you can pin package versions, you snapshot before and after updating...

I don't see how a docker image definition makes any of this easy. There's not even a flag to disallow network access during "docker build".

The claim I'm responding to is "docker image definitions are idempotent as a matter of principle".

The large majority of dockerfiles I've seen are not idempotent. Yes, it's possible to make them idempotent, but they do not make it easy.
I suppose that color-based codes have more density per "pixel" (2-3 bits), so they can be used to encode relatively large amounts of information. Try encoding 1kb as a QR code; it will become pretty unwieldy, if it's possible at all. Think about the size of a reasonable cryptographic public key; would it be nice to have it optically readable sometimes?

Tagging things during manufacture is a different application area, with different constraints and requirements. Bar codes are not gone because QR codes are here, QR codes won't be gone because color codes appear.
The strategy is simple to put into words, but it is still extremely difficult to implement into practice. If it were simple to put into practice, then Neistat would not be distinguishing himself from others.
So typical of Linux kernel code quality: The commit message refers to a missing '=' but the commit actually fixes a missing '-'.

The bad astronomy article says that this one is apparently pointed about 30 degrees away from us.
That language is why I think the authors aren't aware that they are advocating many worlds.

Also, this is a fantastic example of the "don't ask questions" attitude I think is so shameful. If they had bothered to take the small step of asking, they'd have come to a clear, evidence-based refutation of Copenhagen! There are regions of spacetime after the measurement, where the wavefunction is not collapsed, which the authors explicitly point to. That's in direct contradiction to the premise of Copenhagen.

Damn, I love how you've put that.
it doesn't really even describe the relationship accurately- the "slave" symbols aren't doing anything for the "master" symbols, they aren't being delegated to or controlled by the "master" symbols.

"Beacon" and "frame" would describe them better, or even "lord" and "serf" if you really need there to be a power dynamic
Another Aussie here. Try 'very small business' for a laugh.
When I see stories like this one I take it with a grain of salt because I'll be the MTA and state legislature are basically just fighting their budget battle in the media. If the MTA makes a big stink in the media, they can swing voters to demand more funding and more restrictions on ride sharing.

I'm probably being cynical but maybe not.

Eh, no, here in my country nobody uses that units, all the recipes and in the stores, the units are ml, kg, etc
And hook it up to a breathalyzer peripheral so that the level goes up the more you drink.

The forking also seems to have had some unintended consequences of changing the use of hash power such that the main chain is more vulnerable.
Most bit flip events are apparently due to alpha particles from radioactive decay in the package (source - worked for a company which used 'low alpha compound' in some of our ICs to put off having to implement HW error correction) , which would be a big confounding signal. I imaging physics experiments work hard to avoid this, or at least correct for it.
A different approach to attempting something similar (in a wider range):

It's bad.

The A/C/J/Z lines still contain R32 cars, which were built 54 years ago, and are 20 years past their service life. These cars were built before the moon landing, have terrible brakes, have terrible air conditioning, and are, generally speaking, sweltering rattly deathtraps.

The Second Avenue line is 100 years in the making and has a grand total of...drum roll...3 stations. That opened in 2017.

But hey, they're getting WiFi in the tunnels and installing flatscreen TVs in the stations. Three cheers for more ad space! Personally, I'd rather have less station closures, less delays, and less stopping-and-waiting-20-minutes because of track congestion.
Depends on the box. Per core performance is probably your metric there if the app can utilize multiple cores.
Ask HN: Anyone have any Vuejs resources for python developers?
I'm a mostly python backend/data science dev.
I'm looking for any resources to help translate python idioms and design patterns to Vue and ES 6.

Thanks!
The reliability and performance story for Hacker News is not great, and that's despite the fact that its design has lots of simplifying assumptions. I wouldn't call HN a success story for the "just drop it on a server" approach.

Of course, HN is a kind of art project, and its scaling and performance goals are not typical of most applications.
proprietary software frequently inspires foss clones
Because they realized they were in this together, unionized, not just demanded but fought for more rights and a better life balance. Since the baby-boomers more women entered the work force and used their "extra" income to buy things. That lead to inflation of those assets - especially housing. Now people continue to push down labor rights so they make even less than before.

I'm with you though, I find this to be extremely frustrating.
Apparently they can clearly detect that the ejection from the poles is much slower than the ejection from the equator, which tells me the poles are probably directed away from Earth and the stars are being seen somewhat side-on. So I'm guessing any such burst will be directed away.

Just a guess.
Unfortunately bank secrecy is quite over even in Switzerland. They constantly get pressured by the EU to share data regarding EU citizens' accounts. The hunt for taxes is ongoing, under the pretense of preventing money laundering. Yet something in excess of 200bn euros was laundered through the Estonian branch of Danske Bank.
Not sure how they actually classify it, but Square does have Square Capital, which is a product that gives loans to small businesses. It is different than many loans most are used to in that it uses a "Factor Rate" rather than an APR. You pay back the same amount, regardless of how long it takes you to pay. Daily payment is a percentage of what you process through square in a day and are automatically taken out, so you won't miss a payment.

Due to the oddity in how you pay, and the use of factor rates, it requires knowing your business really well to understand what the APR will be. And the better your business does, the higher the APR as you will pay the interest sooner. In contrast, a traditional business line of credit, you will typically have an upfront APR and doing better means you pay it off sooner and pay less interest.

edit: and to be clear, I'm confident that Square doesn't do the scammy practices in the article.
While it does not surprise me that compensation is higher for NYC transit workers wrt national average, it is still striking that the difference is so large. I imagine the avg income in NYC is not >55% more than the national average.
Things I Wish I Knew About Core Async in Clojure
I was talking to a guy at Github who had to debug an enterprise deployment that just stopped working one day.

There was a bit that flipped and apparently took the whole thing to its knees.

This is the stuff nightmares are made of.

Why didn't you open source before ElasticSearch invented something better than yours?

Was the code your core business proposition? I doubt it but still asking.

Was there a bureaucratic blocker -- or golfer-type rich guys with strong bias who simply don't get software? Or was it something else?

I mean, I am pretty sure you guys knew for a long time that this moment has been coming. What kept you from reacting a bit earlier?
A bunch of years ago Cisco had an issue with some RAM in a new switch model, I think it was in the 65xx. They where crashing randomly but only in certain places in the world. Cisco spent tons of money on this. No idea. They brought in a physics professor. The devices with the most issues were located in countries up near the artic circle. Cosmic Rays caused a bit flip in this particular set of RAM due to something in its design. Sorry for the light details, it's been years.

I also worked at a switch manufacturer. We had some ASICs from one of the big companies. Had crashes that we could not explain at all. We knew it was not us. Proved that bits where flipping in the switch ASIC. Turn out they had forgot to spec low alpha solder. Alpha partics will not go through your skin, but when it is layered right on to the chip....oops.
There's a bit more to the story than simply solving a problem. I have other plans for the software and we have ideas about how we want to move it forward.

One of the key features is being able to "tag" an item on someone's wish list as "bought" or "buying". This allows others viewing the list to know that item has been taken. But there's also a requirement that the original author of the list/item cannot see that it has been bought otherwise there's no element of surprise for them come time to open the gift(s) :-)

Spreadsheets don't enable that privacy/secrecy.
Sort of. We didn't have an official way to screen it was more of seeing the same people showing up to learn every weekend at the library and then offering them an opportunity to learn full time.
I don't think it's lazy, I think it's intentional. The cleanup efforts have been in the planning phase for 22 years, so perhaps some fear mongering to drum up more public outrage/outcry is what needs to happen to make someone do something.
This is a really depressing story to read. I've always believed that a good indicator of a country's health, is its ability to tackle complex large-scale projects. Projects that require coordination on multiple fronts: politics, bureaucracy, technical-know-how, civic sacrifice. In the old days when all this infrastructure was built in the first place, we showed our ability to do so. But now, we've gotten to the point where even maintaining it is proving too challenging. When you look at other countries like Singapore, China, Korea and Japan, it's clear that our political and governmental institutions are lagging far behind when it comes to "getting things done". I wonder what this portends for the coming century.
Yes, in fact the L train is automated (or was in the process)

Stop buying crap, and companies will stop making crap
Definitely! I tried to convey that in the article: "And though it is still hard, and potentially risky, if you filter your ideas through this lens, you’ll get much more impact from your own ideas."

I totally agree. I was just telling someone else on Twitter about this topic but I have many more marketing campaign ideas that pass the smell test of "will this break expectations" but they make me stressed to pull off. They risk life, property or reputation. So yeah, they can be super difficult. And they don't just come to me overnight. The campaign I mentioned in the article took me months to execute on the way I wanted to.

Edit: And one more thing I'd add. Putting more work of ours through the filter "will this break expectations" doesn't have to have as lofty of a goal as Neistat level virality. I think most of us asking this of our blog posts, videos, apps, etc. would vastly improve the success of our work to a degree still plenty big enough for us.
That's because the parent poster's numbers are heavily massaged, and include non-union, and executive compensation. Average salaries for people actually operating the trains are ~$22-30/hour.
There's actually been a ton of disruption of this space in the past 5 years. OnDeck, Kabbage, LendingClub, Square, are all great, established tech-lending companies. But the remaining victims are the bottom 20% of the borrower population - it's basically not possible to profitably fund these people unless you're straight up scamming them. So the solution has to come from regulation, not the market.

Base salaries probably give an especially incomplete picture of total compensation for union workers, where overtime pay can be 4x your base, and benefits are nearly "cop from the 50s" insane.
Great find. And somewhat surprising because hadrons mostly don't survive to sea level. Too much integrated cross-section with the atmosphere.

If you were seeing errors like that with any regularity there's almost certainly a hardware issue on your server. Cosmic ray bitflips are really rare, and tend to be basically invisible until you're monitoring an entire datacenter.
if you have zero utilization, then you should scale down or lower your instance type until you are optimized for performance and cost. Which is easier to do when you are in an environment such as gce or aws.
Jespersen's Cycle
Can you point me to a source for that "about 30 degrees away from us"? I haven't seen it.

And, how directional? All the energy is spread across half the sky? Only 10 degrees? Or only one degree? Is 30 degrees enough for it to completely miss us? Mostly miss us? Or are we still in the danger cone?

Finally, in a binary star system, is that 30 degrees going to change as the stars orbit each other? (Worse, IIRC, there's a third, more distant star. Can it change the orbit of the other two in a way that shifts that 30 degrees?)
They have donated, yes. Most of the donations came from friends made at previous companies I've worked at (Google and Apple). Apple is the most generous when it came to company matching.

I haven't had time to look for sponsorship yet, our numbers are pretty low and I've been focusing on each student, one by one.
You're mixing up a few things. Investors/clients are usually other funds, which have their own corporate structure, etc. In any case, protection/limiting liability is the responsibility of each individual (institutional) investor.

All I'm saying is, it's perfectly reasonable to have money in a managed account. That might even be much more respectable! Imagine I'm a small, unproven but promising fund manager... What is going to be easier, convince a $10bn pension/endowment fund to give me the money (that I then channel into offshore corporations "for tax purposes"), or to give the money into an account at some reputable investment bank like BAML or GS and only allow me (or anyone else) to invest/direct/manage that money (in strictly defined terms that are under control of the custodian bank, e.g. delta limits, or asset class/stock restrictions, etc.)?
Agree. The difference between watching "HDTV" on Comcast vs Verizon FiOS was like the difference between watching SDTV and HDTV, with Comcast being SDTV. Everything is so pixelated and "smeary" on Comcast whereas FiOS buttery smooth and fully detailed. I should have noted the bitrate of the two at the time as I use cablecards and can see that data, but FiOS had a MUCH higher bitrate (when comparing 720 vs 720) and most channels were broadcast in 1080 instead of 720. I think it's because Comcast keeps upping their internet speeds, which they need to rob the bandwidth from the tv side to do. They also still simulcast broadcast everything in SDTV wasting bandwidth. How many people actually have SDTV sets anymore? Cable bandwidth is simply outdated with current societal needs, just like the telephone line was 10 years ago.

This is already happening. People are using "containers" the way that they used AMIs, which is the way that they used VMs: as a black-box execution environment that magically abstracts all problems. Until something breaks. As soon as you have to upgrade or fix anything inside the container, you're back to the same old set of challenges, which remain unsolved.

But this isn't really why people are using containers. Probably the biggest reason that folks are stuck with this complexity (outside of big server farms) is because containers are being foisted upon them by companies who want to sell software, but don't want to solve deployment issues. Why plan for execution in an uncertain environment when you can just require Docker?

This is why other cities have shitty transit. Commutes can't be looked at as the only purpose of a transit system. Especially in NY, it's the PRIMARY mode of transportation for a lot of people. Making it shitty outside of commute hours is not an option.

The article is 90% on the political mismanagement, but you instead focus on the workers with little influence making $150k in NYC, much of which is from working overtime well past 40 hours in a mostly mindless job.
What about a train that idles for an extra 0-15 minutes, in order to make sure that it arrives on time, because there is 15 minutes of headroom baked into the schedule?

My dear boy, [redacted]. I wish I was at your work place to help you but alas, I am not so this short message will have to suffice.

There is a lot of different parts for improving your social skills. Just getting out and talking to more people is probably a good way to start. But you probably want specific instructions? :) If your anxiety stems from some insecurities that you can help to reduce that would be a good idea to do. Starting going to the gym was really life-changing for me. Again, I wish I was there to show you how easy it actually is once you get past the initial discomfort.

But social skills, yes. Having a great group of friends whom you can talk to in regular basis I think is an excellent way of keeping those skills sharp. However, if you find yourself lacking on that part and have been for a long time then it's kinda difficult to start. What I recommend then instead is starting a hobby in which you can practise them. I have myself enjoyed improvisational theatre immensely! Hopefully you can find a group that is beginner friendly and you can get over your performing shyness (I am still not there and I have been doing it for two months).

Anyway, probably any hobby that requires high amount of social interaction is good. Impro, I think, forces you to build up that wit and social finesse which helps a lot with any basic interactions. Building up social skills *will* take time so don't give up when you feel that it's no working. Reading up a book or two won't help you I'm sorry to say, you have to get out and do it - whatever form it might be. It's doable, the only limit will be how far you are willing to go.
