Shakespeare famously wrote that a rose by any other name would smell as sweet … but, alas! ‘tis not so for mobile apps. At least not the Stack Exchange mobile app that we launched back in 2014. Without that sweet Stack Overflow name, some of you never discovered that you could use it to view, answer, post and vote on Stack Overflow questions.

So we just launched the new Stack Overflow Official App that lets you … (drumroll, please) … view, answer, post and vote on Stack Overflow questions. Both iOS and Android versions are now available for download. The Android app is currently in beta. All of the functionality is working, but we are making small tweaks to the user interface. …

So I took a look at the official service manual for the Lenovo Flex 4-1130 and it looks like it takes a 2.5", 7mm z-height SATA disk (page 34, PDF page 37). This means there is a measure of upgradability; however, spending extra money on a SATA SSD and dismantling the system to install it defeats the purpose of buying such a cheap system in the first place.

Exploring the State of Mobile Development with Stack Overflow Trends

David Robinson on May 16, 2017

In honor of Google I/O 2017 and the launch of the official Stack Overflow mobile app, we on the Stack Overflow Insights team are sharing a look at the fast-paced history of mobile application development.

We can do this with the recently released Stack Overflow Trends tool, which lets us examine what mobile-related technologies have been growing and shrinking in developer activity, and gives us a glimpse of what the future might look like.

The vast majority of Stack Overflow questions about mobile development come down to the Android and iOS platforms. …

2:12 PM

Thank heaven benchmarks indicate this is MLC NAND, with stable 130-150 MB/s throughput over an 8 GB test file. I was worried about endurance.

Gypsy Spellweaver

Yes, didn't try the first one. Same song. Fits the SS Burgi well, though

Burgi

@GypsySpellweaver how do you cope without cat videos?

bwDraco

..or not. It is in fact TLC. However, the SLC buffer seems to be huge (at least 8 GB).

I'm not running any more tests due to endurance concerns. Raw NAND is probably 96 GB if all of it were TLC.

satibel

I think Imma rage over an "API"

so far I know I can get my data (depending on "random") as jpg, HTML, and pdf inside an Iframe.

bwDraco

I am not willing to torture-test devices like this when the endurance is so limited.

The big SLC buffer does help, though.

satibel

2:25 PM

the range for endurance of tlc seem to be around 1k-10k full writes.

bwDraco

1000 writes is typical.

At least it's 64 GB and not 32 GB, though.

Devices with 32 GB not only have less raw endurance, they also need to deal with much more write amplification because the drive is much closer to full. And yet they are typically good for at least one to two years of typical use.

Frequent TRIM will help.

My main laptop's SSD has seen about 21 TBW of writes over 2.5 years of use. If I'm gentle on this thing, it should last longer than the system's intended service life.

64 GB * 1000 writes = 64 TBW.

Besides, these sorts of systems get less I/O than your typical power user's laptop or desktop.

servethehome.com/…

Double capacity * less write amplification = 3-5 year realistic service life (by my estimate)

The battery would most likely fail before the NAND does.

Furthermore, I won't be using this system as much as some people do, since it's meant to be a companion system to my main laptop.

I also won't be clearing the browser cache as often.

I have one tortured HDD that reports 10PB written.

bwDraco

Hmm... So, I am able to realistically get about 5h of battery life under moderately intensive web browsing. Not the best, but pretty good given this is a 2-in-1 touch device.

The claimed 6h battery life is not far off and is realistic for light web browsing/social media/productivity use cases.

allquixotic

@satibel 1. The "percentages" in Task Manager are not really reliable. CPU utilization percentage is divided up amongst all your virtual cores, so if you have 4 cores with HT, one core pegged is only 12.5%. But many systems will experience significant slowdowns even with one core pegged.

2. Network "percentage" is basically meaningless, unless your actual line speed (how fast your ISP is willing to give you bandwidth) is identical to your "driver" line speed (how fast is the maximum data transfer rate over the physical interface you're connected over).

a coder

what priority does everyone run azcopy at?

allquixotic

For example, if your ISP only gives you 4 Mbps, but you're connected over 100 Mbps ethernet, having your Internet connection actually saturated will only show "4%" in task manager.

Burgi

@acoder priority blue

satibel

3:59 PM

It is actually 2cores, and both go from barely used to 50% max.

a coder

@Burgi where do i find blue in windows?

allquixotic

@satibel There's so many other things it could be. You're not explaining how it's slow or what or any symptoms at all. I'm not going to guess any more.

satibel

Network is essentially at 0% or maybe 20kbps used.

allquixotic

Christ, with you help vampires it's like pulling goddamn teeth to get you to give me information. What are you actually trying to do? What symptoms do you see? Do you have input lag? Render lag (low FPS)? Programs going into "Not Responding" state? Webpages loading slowly? Don't make me guess.

satibel

When I do anything I have about a 50%chance of the program hanging

allquixotic

4:03 PM

What program? What's this "anything"? Like, clicking around in your web browser?

satibel

Though I tried safe mode it doesn't seem to do that anymore.

Sorry typing on phone is slow.

allquixotic

@satibel Obviously you have some background programs (which are disabled in safe mode) that are taking up a lot of resources. Pop open Resource Monitor (you can access it through Task Manager) and look for high disk I/O or CPU or memory hogging processes, and as long as they aren't essential Windows base processes, or something you know you need, try killing it.

And yes, 50% is high. 50% disk write pressure is enough to significantly increase disk queue length, especially on slow NAND or rotating media (HDD).

Burgi

sounds like AV

allquixotic

I mean, 50% of the typical 70-90 MB/s of a HDD is a lot of data throughput. There has to be a reason for something to be doing that consistently.

satibel

I used resmon already to get the i/o ram cpu etc usage

More like 1-2mbps at most.

allquixotic

4:07 PM

@satibel Ignore the overall percentages. Look at individual processes and files, etc. You can view individual write and read throughput on a file by file basis, and see what process is doing it. Similarly for CPU usage, you can look at it by process.

Once your system finishes the initial boot-up, let it warm up for 4-5 minutes or so, then see who's still eating you up.

Burgi

i bet its AV

satibel

My suspect right now is the av locking up

allquixotic

@satibel You don't have to guess; Resource Monitor will tell you. You can look at it, find the offending process, and google what that process is.

Burgi

have you got mcafee with the "scan my PC for updates" plugin installed?

a coder

@Burgi what is blue priority?

satibel

4:10 PM

Ressource monitor doesn't tell me anything, ressources are mostly free.

@Burgi As if McAfee just by itself isn't more than enough to bring a system to its knees :P

Burgi

@acoder i made it up

@allquixotic yeah weirdly this one plugin is even worse

so what priority should azcopy run in if my coworkers like to give bus problems?

Burgi

are bus problems having the weird smelly hobo guy sitting next to you for the ENTIRE journey?

i suspect if you asked your question on the Server Fault main site you might get a better answer than here

I have a problem, it now works with no change made.

@Burgi should I put it in high priority, or realtime priority?

allquixotic

@Burgi No, he'll get laughed out of there and his question will get deleted.

His problem is a social problem; he's been here before trolling and asking us how to solve a social problem through technical means, and we've told him over and over and over that there's no way.

4:20 PM

Msmpeng is MSE right?

Burgi

schedule them to run overnight

allquixotic

@satibel yep

satibel

Might it lock up with avast?

allquixotic

@satibel probably not, but running nested virus scanners always leads to terrible performance; that's why most commercial virus scanners that don't suck (which, apparently, excludes avast) intentionally disable MSE when they install

you should run either MSE or Avast, not both.

one virus scanner is bad enough; with two, the number of context switches and interrupts and signaling that has to take place for a single simple system call like CreateProcess() or CreateFile() is ridiculous; you deserve to pay a horrible performance penalty if you think that's a good idea

i'm not sure if i mentioned this last night or not...

the school my mum is doing supply work for is apple'd up to the eyeballs with apple's crazy educational suite

what they then don't do is provide any training or help to the teaching staff, who's primary skill is concerning children (shudder).

the admin staff at the school all use windows pcs because of the accounting software or whatever

the teachers all have iDevices and macbooks which none of them have ever used

so i had to give my mum a crash course on how to use OSX last night without having a macbook available to demo the principles

i had to find a "OSX for dummies" video on youtube to show the differences in the basic principles

so armed with the knowledge of a 14min youtube video and a few hand drawn (that i drew from memory) diagrams of where to find the basics she was able to do all her lessons today

the school was also so impressed that they have asked her to go back and train the other teachers on the osx first principles...

Ha, you should be offering your services for that sweet sweet cashmoney.

it is a valid point that my mum made though, having all the latest and greatest kit is fine but it is useless if the staff don't know how to use it

as professional geeks we are pretty happy to just swap OS on a whim

if a single youtube video makes my mum seem like a technological wizard and is being asked to train 20 other teachers there is something wrong with the IT policy

i know there are people that will now say "well that just shows how easy apple software is to learn" but this stuff was there for a YEAR

That Russian Guy

10:17 PM

Well, @Burgi, I think you're seeing another side of the line of thought "technology is the answer rather than a tool and part of a process".

In environments with bigger budgets, it can be manifest as "lets throw lots of gadgets and zero training, it will magically work BECAUSE COMPUTERS"

But as a webdev I bet you're much more accostumed to see the scenario of "build a website. I don't know what for, what will be in it, for what audience, there is no layout, we will have the content someday, now hury and put it online"

Both scenarios include zero planning and "IT WILL FIX EVERYTHING BECAUSE COMPUTERS"

I'm kinda getting tempted to do crazy things like setting junction points for things like the Firefox profile.

Gypsy Spellweaver

11:54 PM

@bwDraco Why is that "crazy", and what purpose would it server if you did?

Ben N

I think that would let him store that data on a different volume, freeing up space on his main drive

bwDraco

Firefox can be surprisingly disk-intensive. A junction point diverts all those writes to the external storage medium.

However, this does mean that Firefox will not work without the drive inserted.

sigh

Now I need to learn PowerShell because it's the default for version 1703; cmd is deprecated :(

Ben N

You can turn that behavior off; it's in the taskbar settings

But you should learn PowerShell anyway because it is great and does all the things

bwDraco

@BenN Not just that--Shift+right-click now does PowerShell, and Explorer no longer lists cmd as an option in the File menu.

Gypsy Spellweaver

@bwDraco If you're willing to get stuck with needing the external attached to make Firefox (and other stuff), why not make it also execute from there? Install Firefox, and it's data, on the external. Then you free up even more space for other things on the main drive.
