I hope Samsung does this right. QLC is a big opportunity to make high-capacity SSDs affordable. They can't afford to mess up here.
I think Samsung will eventually replace the MLC-based PRO line with a Z-NAND product. TLC NAND has advanced far enough that the average consumer will never need more performance.
The need for 2-bit MLC NAND has mostly disappeared. Samsung still makes limited quantities of 3D MLC NAND for enthusiast and workstation applications but it's far from mainstream these days.
> Samsung also mentioned that in Q2 2019 they are planning to introduce a higher-performing 512Gb QLC die to complement their current 1Tb die. Samsung compared the performance of this new 512Gb die against an unspecified competitor's 1Tb QLC, claiming that Samsung's high-performance QLC will have 37% lower read latency and 45% lower program latency.
@HornOKPlease if the folder is indexed, it's in a central database that lets it quickly do search string -> filename location lookups, similar to locate on *nix
If it's not indexed, windows has to actually examine the contents of every directory under it to see if what you're looking for is there, which is expensive even on an SSD and shockingly slow (due largely to the seek-heavy nature of the workload) on spinning metal.
Compare locate to find and you'll see the same thing.
Comparing it to ls is not an apples-to-apples comparison because there you already know where the file is, so there's only a single directory to read. ls -R would be a fairer comparison.

Pakistan Telecom's mistake was that it then published that route to its international data carrier, PCCW Ltd. of Hong Kong, Underwood said.
The second mistake was that PCCW accepted that route, Underwood said. It started directing requests from its customers for YouTube data to Pakistan. And since PCCW is one of the world's 20 largest data carriers, its routing table was passed along to other large carriers w…

@Aibobot I'm pretty sure if someone just made a fork with a default homeserver which can't be changed and a simpler UI and default encryption, it could get quite popular
@rahuldottech Ironically, binding to your mobile is what made them popular. The regular user can't remember their password. Their mobile is an easy concept.
@ThatBrazilianGuy all of the above except the hugs made me fat; and nobody's hugged me in years and years (idek when was the last time) but I'm pretty sure those aren't fattening at least
I actually grabbed the !!fuckable code from the bot and put it into a REPL, disentangling it from the internals of the bot to be generally useful: repl.it/@SeanMcNamara1/fuckable
@Burgi No, that's (some of) us; the devs probably get plenty as they're rockstars
@djsmiley2k I think that's a reasonable expectation, but I also wouldn't be surprised to see it traverse stuff in the order readdir() (or whatever the windows equivalent is) returns it; that's easier to implement.
Or just catching up on a feature Firefox has had for five years
Collapsing tabs, plugin data, user data, and eventually users themselves into nothingness seems to be core to Google's philosophy anyway, so it's not like we're ever getting out of that.
Still not convincing me to stick with Chrome, but still 5+ years into procrastinating my switch back to Firefox.
Ironically Microsoft might be Google's saviour in this case in making me stick to Chrome by implementing Android sync features in Windows I've been begging for for years.
@ToxicFrog it only shows up if you've visited the website before and it has told your browser that it has a search engine (iirc). Interestingly, I have absolutely no idea how it does that.
I'd say check out the ultrafast maglev train but I don't think the full line is open till 2025 and I'm not sure the visitor section is still open during the main line construction.
@djsmiley2k Huh. My Chrome doesn't update that infrequently, mostly because my laptop crashes at least once or twice a week and Chrome auto-updates at next launch
Erf damn Wikipedia. Try to look up one thing, end up opening 20+ pages of related articles and guides to editing/fixing errors on said articles
@rahuldottech Clicking on the arrow just takes me to imdb.com
@rahuldottech XML and meta tags. C'mon basic 10+ year old web design
@Bob The line itself no, but the historical development & test tracks are being integrated into the eventual main line as far as I know and they've been open to tourists for decades.
@Bob On a train? Well the original IMT-Advanced 4G definition supposed calls for 100Mbps+ at 350km/h though looking at the actual technical documents referenced on Wikipedia I don't see where that number comes from
@Bob Yeah I was gonna mention, Japan has a history of using awkward and proprietary wireless bands for their mobile services. Not sure where they headed with LTE tbh, but previously it was near impossible to roam into Japan with a non-Japanese phone.
@Bob No, but as a techy who likes trains, I'd consider that a tourist attraction in itself. When I went to Shanghai I made a point of taking the Transrapid maglev for the same reason. Had no particular reason to actually take that transit route, I just wanted to go on the fancy maglev train.
@Bob Yeah I switched my main number to Vodafone over a year ago because of their roaming deals (and their claim of having the most 4G roaming destinations of any UK network)... only got to try it out last week after my contract had long expired anyway, but er... let's just say "quality not quantity" comes into play here
It's more a matter of roaming agreements. Vodafone may get you 4G roaming in more countries, but they're more restrictive in which operator you can use. In Spain for example, Vodafone will only allow 4G roaming on Vodafone Spain. Because Vodafone don't throttle roaming data (only network that does that last I checked) it ironically means I get much faster 4G speeds on Vodafone Spain than Vodafone UK.
However, Vodafone's 4G in Spain is something like 1st or 2nd place for speed, but 3rd for coverage, so when you're in a Vodafone blackspot, you can't use 4G on any other network. EE on the other hand has 4G in fewer countries, but generally has access to more networks in those countries (Again in Spain, Vodafone gets 4G only on Vodafone ES, EE gets 4G on Telefonica (Movistar) and Yoigo)
My other SIM is $50 "unlimited" NTT DoCoMo, but similar ones are 30 GB before dropping to 3G so idk if the description was just wrong. Guess I'll find out.
Telefonica Spain has the best coverage and is tied 1st place for speed, but in a double irony, Telefonica UK has no 4G roaming whatsoever, so cannot use 4G on Telefonica Spain. And how does Telefonica Spain achieve those great speeds? By having refarmed a load of 3G spectrum over to 4G.
So UK Telefonica customers get the worst service when on Telefonica Spain, because a) they can't get 4G and b) Almost all the 3G capacity is gone and c) All the other tourists are on that tiny tiny speck of remaining 3G spectrum.
Huh. Looks like I get approximately one msiexec call (whether it wants to reboot or not) per boot of Windows on my old/buggy desktop install that used to be Win8.1, even though I've done several repair installs
@Bob tl;dr: It's hit and miss. You get more countries, but less networks. If said network has good speed you're fine, but in places like Barcelona they've got excellent speed (over 150Mbps) in places but no coverage at all in others. And you don't get to use the other networks that do have coverage.
Tbh, O2 UK while still openly admitting they have the heaviest throttling, has *somewhat* relaxed the limitations, you'll get something like 8-20Mbps now rather than the 384Kbps initially, and 128Kbps after exceeding the 100MB "fair use" they used to do. That was when they had "unlimited" roaming data prior to the EU regs coming in, you could argue that having unlimited data for £2 a day does warrant some limitations to prevent excessive use, but <0.4Mbps max even when you haven't gotten close to the already tiny fair use limit is pretty heavy handed)
@djsmiley2k Lmao. Actually when I got my contract it was the opposite, Vodafone was by far the cheapest both for UK and foreign use - which partly explains their abysmal UK performance; they give people 4x the allowance for the same cost as other networks while having 1/2 to 1/8th the capacity in some places. Things have turned around a bit in the last year though, and the situation between O2 and VF has reversed to some extent.
@Burgi Oh they do definitely have the best coverage in the UK, and also have had exceedingly good customer service for quite some time. It's their roaming services that suck (and historically, have sucked even worse)
Unfortunately riding on the back of those coverage and customer satisfaction awards, they've also cut back on customer retention budgets. They're now the worst operator in terms of what deals they'll offer you to stay if you call up and say you want to switch to a cheaper network.
Commercially, it's perfectly reasonable. If you're already pulling in more customers than anyone else and poaching customers from other networks because of your service reputation, there's no need to spend heavy on retaining cheap-asses with low standards.
@Burgi Switzerland isn't in the EU and can avoid their laws about roaming too, however the "good" networks have voluntarily included Switzerland in their EU free roaming packages even before the laws existed.
@Bob Things go back and forth quite a bit here (which is one major plus of competition) but Voda is usually one of the cheapest of the big 3 here too. But again that just leads to shite service, winning the worst customer service awards nearly every year since records began.
They shared that dubious honour with 3 (Hutchison) for a few years, but the latter company decided at some point they didn't want to keep getting that award and went on a massive campaign to improve their service and image.
@Burgi Decent service, decent prices, runs on O2 so decent network coverage too. Performance can be flakey due to throttling and corporate shenanigans between the two Beacon RAN "partners" but they've reached a major stepping stone this year in in improving things.
GiffGaff were ridiculed for not having 4G at all in the early days and having hefty markups for 4G packages when they did introduce it, but now include them all as standard just like every other operator. Tbh, the same criticisms did get lobbed at every operator except O2 at the beginning, since O2 was the only one to offer everyone free 4G at no extra cost at the time. GiffGaff probably got more than their fair share of criticism partly *because* their parent network was the first to offer free 4G to all customers.
Looks like foreigners can only watch, not ride, the Chuo Shinkansen test trains at present.
Sadly, the final line will be mostly tunnel so not really much to see out the window, but it's still the first (and currently only seriously planned) >400km/h long distance ground transport in the world. We almost had one in Scotland, the Scottish government were pretty receptive to the idea of an Edinburgh <=> Glasgow maglev link when I went to the international maglev conference in 2004, but that was before the 2007/8 financial crisis
@Bob Sadly, our local claim to fame in Scotland of having the only regular passenger rail service where you can stick your head out the window at over 100MPH will soon be gone :-(
@Burgi It really isn't. I've been on a 430kph train before, and even my 2004 Sony camera had no problem recording a non-blurry video, let alone my much-better-than-2004-camera-tech human cat eyes
Granted, one advantage of maglev trains is running elevated tracks is a lot easier and cheaper, and much of the track was elevated above ground so you had >5km line of sight for most of the 6-minute 20 second ride.
Sadly the Chinese plans to extend the 30km line to 200km for their hosting of the World Expo never came to fruition, partly because of a major (fatal) crash at the development facility in Germany and partly because of political shenanigans including accusations of the Chinese stealing/cloning the German maglev technology.
Oh, and one of them also caught fire (yay for lithium ion batteries specced in the northern German climate being put into use in the sweltering heat of Shanghai ftw)
Until that point they had a cumulative delay over 3 years measured in mere seconds.
And people here moan about driver-only operated trains when completely driverless trains are breaking reliability and safety records every day...
CBTC is a prerequisite for this, but the New York City Subway still uses ancient fixed-block signaling technology. The equipment is so old that the MTA often must make its own parts in-house to maintain the system.
By ancient, I mean over a century old.
Fixed-block signaling operates by detecting whether a train is present in particular fixed segments of the track called blocks, and controlling light signals in unoccupied blocks before the occupied ones. The blocks need to be as large as the trains' worst-case stopping distance, and since they're fixed, they limit how closely the trains can run.
CBTC uses computers onboard each train to dynamically compute the required stopping distance given the train's capabilities, speed, and other factors, and communicate this information to other trains so they can run as closely as safely possible. This enables more trains per hour and therefore more frequent service.
Currently, only one line on the New York City Subway uses CBTC: the BMT Canarsie Line, used by the L service.
