You don't need to shut down the system to clean the stations, that should be happening all the time in a properly managed system. And when it comes to the trains themselves, with extra cars, you can easily rotate stock in and out in order to clean them, or have workers get on the trains at non-peak times (including at night) and clean as the train is in service. You don't need to deep clean each train every day to keep it clean, and with only 2 lines running 24/7, it's not like it'd be that hard to have extra rolling stock just for those two lines while cleaning the trains on non-24/7 lines at night.

Simply put, 24/7 is not as big of an obstacle to cleanliness as you make it out to be.

As other people mentioned, too, most of the work done in the evenings is track maintenance.
The credit system is there to show you can pay your debt. That's important to show that you can pay back a debt, or else why would anyone would let you have debt to them.

You don't need social credit system to prove that you can take a plane. We all can takes a plane, there's no special social skills to takes a plane. This is literally punitive.

Inherently Life already have some kind of social credit system that act like our credit system. That's called reputation, or having contacts, or in slang, street's cred. I can't make a call right now to many celebrities, yet someone with enough reputation, wouldn't have trouble getting in contact with some. In a more realistic context, someone that want to become lawyer NEEDS contacts to make it, that's just the way it is, theses contacts are way, like in our credit system, to prove that you know what you are doing and can do more.

Works does the same with experience.
Because the I/O performance sucks, there's an AV process that goes haywire whenever anything is compiled, the terminals suck, I've not found a non-bad way of SSH'ing into WSL remotely, it's about as clunky as using Wine on Linux some years ago, there's spyware and ads on the enterprise install of Windows 10, software I can't remove by using the tools to remove all other software (installers for Office and the like), but above all, when I'm running the NT kernel, it's mostly to run software that only runs on the NT kernel. I've not run NT on bare metal in a while, but looking at the struggles of people around me, I don't intend to in the near or long term.
>More seriously though: the caterwauling over Amazon's cruel and unusual work conditions is getting a little long in the tooth. I had more sympathy when it's peeing in bottles and passing out from heat exhaustion, but if the above is extent of the complaints now...get over it?

Just because the article doesn't explicitly mention peeing in bottles or passing out from heat exhaustion doesn't mean those problems no longer exist, and I don't see any claim that the article somehow comprises "the extent of" complaints about Amazon.

It does not look good and your content is not easy to read on devices with smaller screens. That's not a political argument, honestly I couldn't care less where you decide to host the stuff you write, but the reading experience medium.com offers on small screens is simply not good.

I will not download an app to read someone's blog posts. I will not dismiss the same obnoxious banner multiple times a day either.
DRAM beats SRAM at density, power, and cost by pushing the refresh circuitry out of the NM memory cells and into the periphery of the NM cell matrix. There are only M amplifiers per NM matrix, so you can only refresh M cells at a time and must perform N refreshes per refresh interval to catch every row. Could you put in NM amplifiers to refresh all the cells at once? Sure, but then we would call it SRAM :-)
> How can you be truly independent and live that perfect magazine cover life if you’ve got to wait on the 9:27 to take you to the B line so you won’t be late to work?

By that stance, no one living in Chicago, NY, or any city with public transit are "truly independent", or whatever. Waiting a few mins for a train or bus is no different than being stuck in traffic.

When I lived in Chicago my quality of life went up precisely because I didn't need to use my car. I never had to worry about finding parking. All I needed to do was learn some of the bus timetables and where the CTA lines generally were.

Hey, it's in to criticize tech companies. That's not to say there aren't problems, but most people get outraged at whatever society tells them to get outraged at in that moment. No thoughts of their own. This place is mostly a safe haven from that.

Now, it will be interesting to see how soon Amazon workers unionize and how that'll play out.
Just to footstomp this, there are other costs that are already beginning to dominate the analysis for solar, like customer acquisition costs. Convincing someone to attach something to their house has significant costs. Like, "over $2000 per install" significant.[0]

Other soft costs, like land acquisition and taxes, still play dominant roles in many projects.[1]

The naive assumption is that solar succeeds when there's lots of sun and it's all just physics.

But these other factors, like, say opportunity costs (the cost of available substitutes), are why you're often better off installing solar in Alaska than Florida.[2]

Theoretical physics are great, but at this point I'd be far more excited about big ideas to deal with the messy economics side of solar generation. An announcement that some sort of "solar council" was going to pursue a national marketing campaign to drive solar adoption would be huge news. Or Elon deciding that strip malls were his new target, to drive installation of solar on every commercially leased roof, which would reap huge efficiencies of scale in local installation costs over residential.

Or, the cheesy TED talk clincher would be: the next big solution isn't always about electrons, sometimes it's about people.

> Their second upgrade they called QUIC (pronounced "quick"), which is being standardized as HTTP/3.

Isn't QUIC new transport layer protocol based on UDP and, if I remember correctly, HTTP/3 will be HTTP bindings for QUIC?

You might think this is nitpicking, but HTTP is application layer protocol, so it's little bit confusing to me.
In the 50s, the US made a big bet that car based transportation was the future. It was, for awhile, but now it's clear that denser cities are the future, not suburbs. Countries that invested in infrastructure that supported dense cities are providing a higher quality of life compared to the "drive everywhere" culture of the States.
The real breaking point will be when solar is so cheap that it costs less to replace a coal or natural gas plant than it would be to continue running it.

I think you are misreading it. The point to avoid locking all the memory each time, instead you only lock (via refresh) a small potion of memory each time.

Ask HN: What prohibits smartphones use as desktops
I am interested in understanding your thoughts on what are the barriers today to turning your smartphone into your main and only computer.

The idea of the carrying laptops when you have such powerful smartphones makes me curious about why are they not converged yet. What prohibits this convergence. Microsoft has continuum and Samsung/android has DeX. But they haven’t seem to catch on like the leap that iPhone made over traditional cellphones. Why?

Is there just a lot of money to be made by companies by not converging and hence execution of this strategy is subpar or are there other genuine challenges that prohibit the convergence?
My 2 cents. Unless you are funded or are expanding in staff over the next year by a significant amount I'd avoid commercial plans until after 15 employees or you have funding and are planning an expansion. Instead, have everyone pick up personal/family plans and then reimburse them for those plans at some rate.

Commercial plans are not easy to setup, take time to maintain and have a lot of variability based on size, demographics of your team etc. So when you are small it is cheaper and easier to use the personal insurance market in the U.S. and just do reimbursements.

Other option is to look at third party companies that do benefits management. There are a number of those around where essentially you and your employees become employees of that company as well for the purposes of benefits management. The costs are not insignificant so you want to make sure you factor this in as they generally manage the payroll and all benefits at that point to make sure taxes etc are managed properly.
I'm commenting on the article that was posted, which describes the "human cost" of Black Friday. I'm asserting that the complaints presented in the article don't sound like some excruciating human cost, it just sounds like...a job.

That the source was tangentially involved in the military makes it even more comical. A job that requires its workers to be screamed at, put through torturous physical conditioning and possibly blown up by bombs, but I guess that's nothing compared to working a 10 hour shift in a warehouse.
It's still relevant because it's for job security.

When IT management needs to decide which product/service to use, they need to explain to the business (e.g. front office) why they choose A instead of B. Showing the report helps.

When product/service A messes up, IT management needs to come up with an explanation on why they've chosen a bad product/service. Showing other products/services look even worse in the report again helps. In other words, the chosen one is already one of the best in the market.

Given that the company pays for the report, why would IT management not ask for a copy as it costs them nothing?

This is not to say all IT management uses it to make their job safe but they can't lose by using those products/services in the report. In other words, they are taking enormous risk using a product not suggested/covered in the report and what would be their incentive to do so especially having gone through the financial crisis?
"I know some cultures don't value human life as high as we in the Western culture do."

I'm sorry, I feel a general agreement with the rest of your post but this line is too much a false claim to ignore. If we're going to generalize on Western culture, I would say that that has a habit of only valuing lives that are Western or lives that are white.

It took decades for there to be even mild acknowledgement that Thanksgiving celebrates the genocide of millions. You revere people like Churchill or Obama who are responsible for countless third world lives being lost. A single American dying somewhere warrants more attention in the West than a dozen brown lives.

Had this American caused the death of 5-6 islanders with disease, I wonder whether it would be front page news. Please don't give me this claim that the West values life more. It is we in the East who suffer the bulk of the casualties of your Western wars.
Why wouldn't it be responsible?

What really worries me is that most non-tech companies (and even some tech companies) don’t understand the difference and frequently allocate resources inversely - paying the equivalent of a Michelin chef to make subs and trying to get top dollar dinner cooked with teams barely skilled in the subject.

The “cloud wage” story could be very compelling in such situations, but it will likely lead to a lot of issues with the more complex systems. Someone has to be the true “architect” and own the successful evolution of the software/business.

Back in 2014, this article struck me as very insightful on the subject: https://www.japantimes.co.jp/news/2014/04/07/business/gods-e...

If you only have automation or low-end jobs, you are going to lose the ability to make transformative/revolutionary moves. You will still have the ability to refine existing processes, but there are definitely diminishing returns to consider.

The other item that’s also glossed over is sheer productivity - when dealing with more complex issues, experienced developers are a lot more productive, so your $15/hr can easily turn into 10-20x more hours with the wrong experience choice, in the end costing you more.

Hate to use a cliche, but “the right tool for the right job” applies to software too.

In terms of power / weight solar can already beat many IC engines.

The only thing more efficient solar brings is less packaging and use in extremely confined spaces like the roof of a car.

PS: The car thing should start taking off in a few years. A Tesla model 3 is 4.6 meters long 1.85 meters wide so 8.7 meters square. At 40% your talking about around 30kwh per day which could really extend the range and for less used cars minimize recharging.
I have a few war stories about this from back in the day when I worked in hardware design: we made a chip that was supposed to have embedded SRAM but the cell design vs process was a bit off and it turned out to leak charge slowly, making it a DRAM. No problem : we modified the software to hit every row every so often which in effect implemented refresh. Also the converse problem: if you have a bug in your hardware that results in refresh being disabled it can be hard to detect because as noted above cells typically have a retention time on the order of 10's of seconds. Add in the effect of programs running, which causes accesses that as a side effect refresh the row targeted, and it can take a long time before you realize there is no refresh. The symptoms can be subtle and confusing, because for the most part memory _is_ being refreshed, just not in the way you expect.
What you're referring to is called a "cold boot attack".

Does anyone have any solid numbers for this? When I've been in Asia buying cheap clothes usually the quality is terrible. Branded stores in Asia seemed similarly expensive still. In US outlet malls I regularly see Asian tourists from many countries buying clothes to take home.
The failure of Americans to recognize death panels as a feature rather than a bug are why American healthcare can't be done on a nationalized basis. As to the misunderstanding, I assume that's based either on a misstep in logic, or on moral repugnance for it.
>With QUIC, however, the identifier for a connection is not the traditional concept of a "socket" (the source/destination port/address protocol combination), but a 64-bit identifier assigned to the connection.

Insurance is a business, and of course it should be profit-driven. Competition should keep excessive profit-taking in check. A problem with health insurance is that regulations prohibit very much competition.
It's not about money, it's about time, flow & motivation.

Time is the biggest obstacle, side project implies that there's another full time job. With a full time job and other obligations such as family or volunteer activities.

Without enough long stretch of time, it's difficult to get into a flow state.

Without enough flow while working on any project motivation wanes.

The secret becomes figuring out how to manage your small chunk of time, how to get into flow fast, suspend it and resume it across time and how to keep the motivation up if you miss out on flow.

I live in SF and have for years. My partner was born and raised here.

There are tech companies in SF but it’s vastly dwarfed by FAANG in SV. You could argue SF is a suburb for SV but I’m not sure how that would make the city any more important or interesting.

Due to insane housing costs you’re more likely to meet a younger person born and raised in the Bay Area in some Midwest city (like Chicago) unless they’ve decided to live with their parents.

The interesting culture of SF is in rapid decline. So what you end up with is a dying culture in a city funded by tourism (also in decline because of chronic homlessness) inhabited by transplants who don’t work in the city.

Is that important? I don’t know? Maybe it’s an important model of how not to run a city.
This ought to be a teachable moment in labor/market regulation. Imagine how society would have been bettered had workers not been stiffed? The impact to aggregate demand is always going to be larger when more people receive income as opposed to fewer people with larger sums.

Edit-instead, the bankruptcy is engineered to take money away from pension and laborer obligations and give it out to top executives. Apparently there’s some regulatory loophole that only allows laborers to be paid out in this situation if they demonstrate excessively high productivity- and without that management gets paid. Despite the fact that this same management is responsible for destroying the company.

Purely infuriating.
Sorry, there is a misunderstanding. It's the other way around. I believe the black mirror system is more efficient to establish social control and is more perverse because everyone is policing it, watching you and reporting you. It's the real nature of big brother (what I remember from the book): everyone is big brother in the end and there's no escape.

Our life would be worse in a black mirror system than in a Chinese system.

Both systems are fucked up though.
>However, in those discussions, a related concern was identified; confusion between QUIC-the-transport-protocol, and QUIC-the-HTTP-binding. I and others have seen a number of folks not closely involved in this work conflating the two, even though they're now separate things.

>To address this, I'd like to suggest that -- after coordination with the HTTP WG -- we rename our the HTTP document to "HTTP/3", and using the final ALPN token "h3". Doing so clearly identifies it as another binding of HTTP semantics to the wire protocol -- just as HTTP/2 did -- so people understand its separation from QUIC.

TL;DR the rename is to resolve the confusion.
I don't the your part you've quoted undercuts the point at all. If I have a PhD in the area of algebraic topology, I do not expect to get out of band comp for teaching middle school math. If the job only requires a high school diploma, then that's a great salary in most areas.
As the benefit to each next generation of chips becomes lower and lower though, that might not matter as much to some countries as independence. For example, I've read that Russia manufactures some of its own computer chips for military purposes where it doesn't trust imported chips.

If any country wanted to, I'm guessing they could manufacture CPUs that would've been top of the line 10 years ago, and honestly, for most applications that would be good enough.

It also might be that individual countries would manufacture chips for certain applications, and then they could buy the "world's top of the line" from Intel, Samsung, and TSMC just for high end business or gaming machines, which is a smaller market than the total market for all tablets, phones, IOT devices, etc.
I have to disagree. I perform a lot of interviews, in-person and over the phone, and I no longer trust resumes. People will put hundreds of words on them but can really only speak to a handful. I’d rather sort that out over the phone first before wasting their time taking PRO and traveling.
Thanks for commenting, good information.

It's a useful distinction: perhaps Finland isn't protesting SA's involvement per se. Rather, one can be neutral about that, or even support it... but not support the incompetence of how that intervetion is executed, i.e. resulting in the deaths of children and civilians. Makes a lot of sense.

Edit: And I'm now thinking about how well those can be separated. Could the military intervention continue, but change in a way that dramatically decreases innocent victims (or relatively innocent, etc.)? It seems like that ought to be possible. But I don't know the situation on the ground.
Are you paraphrasing? It doesn't have the same effect.
That was my point, just being a capital doesn't say much and it's not a real factor when it comes to the importance of a city.
