i love me some crappy earbuds
 
6:21 PM

@BenRichards stuck with bad earbuds? or by choice?
 
🐇
🐣
🐏
Google's emoji can be so cute 😃
 
@allquicatic Sorta both. By choice, since I wanted portability, but stuck with the crappy wired ones because the bluetooth ones that actually seal the ear canal that I have likely have dead batteries, since I haven't used them in a long time.
Best I got so far. That 280Hz frequency seems to ring quite a bit on these.
 
first day at weork was good :O

Q: HP Envy 17 3D 2199 el is incredibly slow

Daniele CBack in 2012 I bought this laptop which has the following specs: Intel Core i7 - 2630QM @ 2.0 Ghz 8 GB DDR3 RAM AMD Radeon HD 6800M / Intel HD 3000 I even bought a Sandisk SSD 128GB (with windows 10 home installed on it) that I have installed along with the 1TB HDD (that I use for Data) The ...

 
sounds like swapping to me
get more memory
 
how can 8gb not be enough even while only using file Explorer?
 
Couldn't be swapping unless most of that RAM is bad and Windows only sees like 2 GB or something
 
on the computer properties <i can see all 8GB of RAM
 
6:39 PM
> it takes minutes even to load Edge, It is always hot and with fans spinning at max speed.
Something hogging the processor?
 
@DanieleC win 10, 2012?
 
This does not sound like disk thrashing.
 
souinds like bad drivers, cpu trottling
 
All I can think of with the combination of slowness, lack of CPU and disk activity, and no swapping, is a combination of the processor being very underclocked + bad graphics drivers causing you to always use the discrete graphics chip rather than the cooler and less power hungry Intel HD 3000 graphics.
 
is the unit making crunching noises?
 
6:42 PM
A better question to ask is "is the disk activity light constantly lit?"
 
Though actually, it could just be bad grpahics drivers so it's only using the hotter AMD graphics chip, and if the cooling in the laptop is poor enough, it may be throttling the CPU and memory down significantly to prevent damage.
 
Please have a look at the question again that I have updated with images
 
I would probably check that the airflow is good, reapply the thermal paste on the heatsinks, and then see if it runs as hot and slow. A faster check would be to see if you can force it to use the Intel graphics (if it is indeed just using the AMD graphics chip)
I'll post as an answer
 
@bwDraco Yes the hdd light is Always lit
 
Okay, so this is disk thrashing. Any idea what's causing it?
 
6:46 PM
what exactly is disk thrashing?
 
Odd. I see little disk activity on Task Manager.
Go back to the Processes tab and sort by Disk.
 
Disk thrashing would occur if it swaps heavily. Basically that means it's reading and writing to the chip at an extremely high rate, possibly saturating the SATA link.
 
look in Resource Monitor
under disk or CPU
 
here is the task manager sorted by disk
 
6:51 PM
is it windows 32-bit or 64-bit?
I glean it's probably 64-bit from the "(32-bit)" in Task Mgr
 
Probably 64-bit since it sees all 8 GB of RAM
 
64 bit
 
I'm pretty sure while there's probably a 32-bit Windows 10, it might be very difficult to get your hands on, relative to 64-bit.
 
Cortina!!! <waves fist at skiy>
 
I posted an answer with my suggestion. It may or may not be disk thrashing.
 
6:53 PM
hmm, could be a defective SSD
or, if this is a very low-end SSD, it might be bottlenecking -- low-end Sandisks don't have a DRAM write cache
 
Is there anything on the HDD? You did install on the SSD, right? Old laptop HDDs are very slow in my experience anyway, no matter what chipset you have.
 
I don't think it's the SSD since it was doing the same things before
 
4 yr old -- failuing ssd?
 
@Bob Nope :-|
 
the SSD is new on the HDD I only keep my data
 
6:54 PM
'before' what?
 
OS is on the SSD
 
I doubt it. Unless there's data loss, SSDs tend to just stop working, I'd think.
 
before I bought an SSD an put it along side it
 
hmm... would be interested to see how it performs on an Ubuntu live CD
could use a disk benchmark from Ubuntu to see if the controller is operating in a very slow mode or if the disk subsystem is just very slow
and can check dmesg for ATA transfer failures, etc
...wait
this is Sandy; could it be a failing SATA controller on the chipset?
the thing they recalled?
 
Unless it's a slow SATA connection, which would throttle any fast SSD or other HDD, I'm standing by heat + poor cooling (and possibly shoddy thermal paste quality) = heavily throttled CPU and RAM.
Can you see if the CPU is running at speed?
 
6:57 PM
@BenRichards the task mgr screenshot shows the CPU running at 0.82 GHz and 1% utilization
 
It can be throttled while still at 1% utilization. Is 0.82 GHz fast for this chip? I don't know, myself.
 
@BenRichards 0.82 GHz on a Sandy Bridge-HM is definitely fast enough to start up a browser in less than "minutes"
 
it is a 2 GHz chip so it is pretty average i think
 
like I said, eliminate the driver factor first; put Ubuntu 16.04 64-bit on a thumb drive and boot it up
from there, run some disk I/O benchmarks against your SSD and HDD
 
6:59 PM
ok I can do that
 
if they're not running well from Ubuntu, you know you have a hardware problem
 
which benchmarks should I use to check for this problems?
 
I suspect the driver is the reason the fans are high and it runs hot. It uses switchable graphics and it might just be using the discreet GPU all the time.
If it's not throttled due to heat, though, then the speed might be entirely unrelated to that.
 
It could be, how do I force it to use the intel graphics instead?
 
You'd need working Intel drivers for Windows 10 to do that.
 
7:01 PM
aren't they already installed?
 
It's a 4 year old laptop, the drivers may not work properly on Windows 10 if they were made for Windows 7 or 8.
 
it was using to have the same problems even on Windows 7 though
 
Generic drivers might make it just use the discreet graphics chip, or just the Intel chip. I don't know. I don't have lots of experience here.
I think you can check which GPU it's using by checking what the graphics adapter is reported as in display properties.
If it was doing the same in Windows 7, and I'm presuming the drivers worked fine there, then it running hot might just mean lots of dust or bad thermal paste application/quality or the like.
 
just look in driver manager and see what's there in terms of display adapters
 
Check your disk I/O though, that's a good avenue for the slowness.
Sounds like you have two separate issues--slow performance and it's running hot.
 
7:04 PM
@BenRichards yeah, but that's incongruous with the perf issue; running off discrete graphics should be faster than running off the IGP
 
it's running whit intel graphics 3000
 
the running hot could be because you have it set to High Performance profile :P but then you wouldn't be seeing 0.82 GHz out of 2.00, hmm...
 
@allquicatic It shouldn't matter when launching a browser. The only performance increase you may see in regular Windows operation is less choppy animations (like when dragging windows around)
 
I have it set to balanced profile
 
I'm starting to suspect the possibility of a rootkit that's making you mine bitcoin or participate in a botnet (one that cleverly hides itself from Windows' performance counters) :/
again, running Ubuntu should eliminate that as a potential factor
 
7:06 PM
what software should I use to check the disks on ubutnu?
 
Also a possibility. Rootkits are sneaky like that.
 
well the built-in Disks application can do disk benchmarks, I think
you want to be careful because it may want to wipe the HDD to do a benchmark
I'll poke around and see if there's something better
 
thanks
 
I haven't done disk I/O benchmarking in a very long time.
 
7:08 PM
i don't think its a rootkit cause I bought a brand new SSD I installed a fresh copy of Windows 10 on
 
before you reboot into Ubuntu, from Windows, run crystal disk mark: crystalmark.info/software/CrystalDiskMark/index-e.html
if at least the SSD's performance is what you expect (should be at least more than 250 MB/s read and write for sequential), it's probably not a disk issue
 
Rootkits can live in firmware, can't they? Wasn't there something like that going around?
 
@BenRichards yes, they can live in either the BIOS/UEFI firmware or the NIC firmware even :P
theoretically the GPU firmware if it's writable
ooooor....
if she didn't wipe her old files from the HDD when reinstalling Windows...
maybe she opened a document or ran an application from the HDD that transmitted the rootkit into her present install
 
Yeah. Lenovo was caught basically with their own rootkit in some of their PCs that got installed even after a complete wipe because the Windows install allows loading of drivers from UEFI, which has a legitimate purpose for automatically loading drivers if needed.
But that can be exploited.
 
I can't imagine criminals are sophisticated enough to write multi-platform firmware-resident rootkits though, so hopefully "the Ubuntu test" should yield good performance and low fan speeds and we can move forward from there
(APTs are sophisticated enough but we presume our friend here is not on the NSA's shortlist)
 
7:12 PM
@allquicatic Yeah, I'm just saying, it's one way if it was a rootkit that it could've survived a SSD upgrade and a clean reinstall.
 
@BenRichards it's far more likely they just ran an .exe from the HDD after installing clean on the SSD but not wiping the HDD
 
Or it was an infected USB drive, yeah.
 
any self-respecting rootkit would mangle as many .exes on the system as possible to guarantee its spread
 
Anyways...
 
ok I am running the disk benchmark
 
7:13 PM
probably also want to verify the SMART status of the disks and make sure they're using AHCI instead of some old horrible SATA protocol
like back in the IDE days when sometimes the IDE controller would fault you back to PIO mode
limited to some ridiculously slow transfer rate
 
A 2012 laptop shouldn't be doing that :P
 
unless it has a problem
 
the benchmark on Windows is showing 314 mb/s read
 
and 190 write
 
7:15 PM
@DanieleC that's a little slow for an SSD, but within reasonable expectations for a budget 128 GB SSD
that's about 2 to 3 times faster than a typical hard drive
 
its a Sandisk ultra II SSD
 
so not the cheapest
 
open a command prompt for me and run this: wmic idecontroller get deviceid (it's from that article, to check your controller version)
look for "REV_" and provide the number after it
 
I get "there are no instances available"
 
7:20 PM
o.o
 
my bad
didnt put c instead of deviceid :)
what should I write exactly? this did not work too
 
wmic idecontroller get deviceid
it might not work in Windows 10; anyone else try it? I'm on a Mac ATM
 
Works here
 
I can try it on my Surface
 
it does not seem to work
 
7:22 PM
what does it give you back? @DanieleC
 
please @BenN
"there are no instances available"
 
that's kind of worrisome...
 
Doesn't work on my Surface
 
same error @BenRichards?
 
Yeah, @allquicatic
 
7:24 PM
haha, there's an even easier way to get at it that's GUI Driven
 
Device Manager?
 
yup
 
where in the device manager?
 
@DanieleC look for a device under "IDE ATA/ATAPI controllers" in device manager
 
in control panel
or type 'device manager' in the start menu
 
7:25 PM
right-click, properties, resources, Hardware ID
Details, not Resources, sorry
 
@DavidPostill Should be playing in your browser: picosong.com/zrq7
@Bob Looks like Reddit or something. But here is the sample: picosong.com/zrq7
 
example of what you're looking for (this is from a newer system, but same idea): PCI\VEN_8086&DEV_8C03&SUBSYS_2101103C&REV_04
 
@ThatBrazilianHeadlessHorse Tried it and Sony's app and Shazam but they did not recognize: picosong.com/zrq7
This song reminds me of Linking Park. Especially their vocalist.
Not a chance it's them.
 
@Boris_yo Linked.in Park? ;-)
 
I can't find the hardware id
I got this
PCI\VEN_8086&DEV_282A&SUBSYS_159B103C&REV_05
 
7:28 PM
@allquicatic Copyright claim would be waiting to happen...
 
so it should not be affected by the bug right?
 
@DanieleC yeah, you should be safe from the bug; but I'm a little concerned that it's in "RAID mode" instead of AHCI
 
I should chenk in the bios maybe
 
you can't benefit from Native Command Queuing unless you're in AHCI mode
@DanieleC yeah; if it says "IDE" or "RAID" for the SATA controller mode, try changing it to AHCI
hopefully Windows 10 is smart enough to still be able to boot your system :)
 
ok I'll try
and I will let u know
thanks a lot
 
7:32 PM
Last time I tried changing the controller mode, Windows proceeded to wreck the boot configuration data, rendering the OS unbootable even after changing the mode back
 
@Boris_yo Hmm. No match :/
 
@allquicatic My Surface has the SSD connected via PCIe. :P
 
@BenN ...yikes
meanwhile Ubuntu's like *shrug* you could dd me to a thumb drive and I'd be none the wiser
 
@DavidPostill Like the genre?
 
I've switched between AHCI and RAID mode before. I only had to make sure I had RAID drivers installed (or AHCI drivers, going the other way) otherwise it couldn't find Windows and would report no bootable OS found.
 
7:34 PM
hope this doesn't brick @DanieleC's system
 
It wasn't bricked, fortunately, I just had to reconstruct the BCD
 
funny how I say "bricked" as if it's a mobile device... ha ha, you can't brick a desktop or laptop, without pulling the power while flashing firmware... right? right? :)
but how many people do throw away a laptop or desktop when they get a BSOD...
 
rm -rf / can blow away the UEFI variables, which would cause Very Bad Results
 
@allquicatic rm -rf /var/uefi
 
@Boris_yo Not really :)
 
7:36 PM
@djsmiley2k oh yeah O_O I remember that
@BenN is it still recoverable at all after that?
 
@DavidPostill What genres do you listen?
 
holy balls that's stupid then
 
yus
 
I wonder if hosting providers with UEFI server mainboards have lost any motherboards to that
OVH etc
 
7:37 PM
iirc it's due to a bad uefi implementation
so not everytthing is affected blah blahj
 
hope supermicro is ok
 
There was also a small debacle in which Samsung laptops' UEFIs behaved in a weird way that made booting Linux on them wreck it forever
 
@BenN wat
 
!!wat
 
oh, there was also a totally unrelated debacle with Ubuntu a few years ago, involving HDDs, where a critical piece of configuration in a Debian package, setting the HDD spin-down time, was set to 0 seconds -- so after 0 seconds of inactivity the disk would attempt to spin down, and then would immediately come awake again
as you can imagine, this wore out the mechanism for putting the head on and off the platters very quickly and killed drives
 
@allquicatic More modern version: Should make sure you're running in NVMe mode not AHCI
 
Here's a blog post from a more technical person when it comes to Linux and UEFI: mjg59.dreamwidth.org/22028.html
 
@kerbalspacecat more modern version: should make sure you're running in Native Quantum Logic (NQL) mode, not NVMe :P
 
@allquicatic Ok, so I was curious. Since the SSD is connected via PCIe, I had to use this instead: wmic scsicontroller get deviceid
 
7:41 PM
@BenRichards interesting :)
 
@Boris_yo A lot - but not that :) Ambient, Chillout, Classical, Electronica, New Age, Latin, Tribal, World music, Some rock ...
 
Yep!
 
@allquicatic You missed out 3DXpoint!
 
@kerbalspacecat does 3d crosspoint need its own new storage I/O protocol though?
 
@allquicatic Maybe?
 
7:42 PM
I think conventional NVMe or even AHCI should work in principle (though AHCI would not take advantage of its raw speed)
 
I got (typed, so could be wrong, but yeah) PCI\VEN144D&DEV_A802&SUBSYS_A801144D&REV01\4&25BACB6&0&00E0
 
I doubt you can use it as persistent storage in any old DDR4 slot if the EFI treats it as normal RAM
 
crosspoint is being used as persistent storage so it will be attached to the I/O subsys, not installed as system RAM
 
Says it's using the "Surface NVM Express Controller"
 
they might release a product later on that acts as main memory
 
7:43 PM
I'm back, there is no such option in my bios
 
SSDs over PCIe have been a thing for years though, @allquicatic?
 
@DanieleC good, because @BenN thinks it could possibly make your system unbootable if you changed it :)
 
Oh you're talking about somethign else
 
> After all, SATA, SATA Express, and even PCIe lack the sheer bandwidth to support the levels at which 3D XPoint can perform. But this week Intel officially revealed its plans for 3D XPoint memory support: It will slip into a DDR4 slot, and it’s a decision that won’t make vendors happy.
Have they backtracked?
 
7:44 PM
@kerbalspacecat oh ok, that's newer info than what I was working off of
the initial speculation when it was announced was 100% "this is the next SSD"
 
Is there something else I could try?
 
@DanieleC I still think an overall system usability test, benchmark / SMART self-test in Ubuntu on a thumb drive would go a long way
 
Ok I Will do it.
 
if we can get good I/O perf out of your disks and good system usability (web browsing, etc) on Ubuntu, we know something Windows-related (driver? rootkit? something...) is bad
keeping in mind a USB thumb drive as your system volume will be a bit slower than an HDD, but if it ends up being faster for usability than running off your SSD, you know the problem lies in Windows somewhere
 
@allquicatic To be fair, the article is nearly a year old, and the recent "demo" units of Intel 3dXPoint have been PCIe Optane drives
> In the week of Intel's Developer Forum we have heard its Optane XPoint SSDs and DIMMs may be delayed.

We are hearing that the first version of XPoint chips can only be used for SSDs. A second, more developed version is needed to make XPoint for DIMMs. That means XPoint DIMMs may not appear until 2018, which would give competing non-volatile DIMMs more time within which to establish themselves. If true, this means Diablo and Netlist get more breathing space.
 
7:47 PM
I already have got a DVD with Ubuntu 16.04, Can I use that
?
 
@DanieleC sure thing :)
 
Ok
 
boot time and first time application launch will be slower than a thumb drive
@kerbalspacecat hah, so my initial impression was accurate then? :P
 
@allquicatic Heh, you knew before Intel themselves did! :-P
 
Intel should take me out of my basement once a year for allquicatic's day at Gobbler's Knob in Punxatawney, Pennsylvania to determine if Intel's next product will be delayed or come out on-time
I'll make some vague meows or something and the Mayor will go, "And it seems you'll have to wait six more weeks for Intel's next processor, folks!" to the crowd going "Awwwww!"
 
7:51 PM
Once a year is an extremely long time in the tech world :-(
 
@allquicatic Like that dog/horse/turtle/whatever it was that predicted some football match scores some years back?
 
so who here is preordering the iBone 777-ER on September Ninth Twenty Sixteen?
it only costs $631 Million USD :)
those sweet dual-core GEnx engines
 
!!tell 32148498 wat
 
Paul the Octopus (26 January 2008 – 26 October 2010) was a common octopus who supposedly predicted the results of association football matches. He made many accurate predictions in the 2010 World Cup which brought him worldwide attention as an animal oracle. During divinations, Paul's keepers would present him with two boxes containing food. Each box was identical except for the fact that they were decorated with the different team flags of the competitors of an upcoming football match. Whichever box Paul ate from first would be considered his prediction for which team would win the match. His...
 
@kerbalspacecat Octopus
 
@DavidPostill this is perhaps the only time I've seen a chat line consisting entirely of a reply with the word "Octopus" that made perfect sense in context
 
Is there another new 777?
 
and I may never experience that again
@kerbalspacecat Yes. Stack three iBone 7s together and you've got an iBone 777.
oh wait, the 7s isn't until next year ;)
 
It boots Windows I am not able to boot from cd
In the bios it' s enabled though
 
7:55 PM
@DanieleC you have to use the boot menu to tell it to boot from the CD - I don't know what key you have to press, it varies
F10, F11, F12, Del, Windows Key + PrtScr + Pause + [, Brightness Up + Power, who knows
 
I did
 
XKCD needs a comic about that... combinations to press to get to the BIOS / boot menu
 
Still It boots from hdd
 
@DanieleC hmm, maybe the DVD is damaged?
 
I'll create a thumb drive i guess
 
7:57 PM
I want to press that key for the boot menu
the hiss key ;p
 
@DavidPostill interesting... a lot of intersection with stuff I like there
you have Spotify?
 
@allquicatic Nope :/
 
hmm, who can I kick off of my spotify family subscription
 
Remember I'm a on a 10 GB / month total bandwidth ... (mobile tethering).
 
8:09 PM
Spotify is going to get suspicious if 3/4 of my family members are outside the US constantly
 
@allquicatic lol
 
already have a Brit and a Canadian on there
and someone who constantly travels but is based in the US
@DavidPostill oh, that sucks. well you could just download all the music you like to saved offline spotify playlists and tell it to use the lowest available quality (it's still very good quality IMO)
 
@allquicatic I already have 150 GB in iTunes and another 125 GB as yet uncategorised (as it wont fit on my iPod) :)
Not much from the last 18 months since I lost my fast connection ...
 
why'd you lose your fast connection and get stuck with 10 GB/month?
 
@allquicatic Long story short - lived in NL, lost job, split up, lost house, moved back to UK, unemployed, ...
 
8:17 PM
:(
no landline?
 
guys I'm gonna try tomorrow to run ubntu and do some tests
 
@allquicatic yes, but could move at any point. don't want to get tied into 12 month contract.
 
I have really appreciated your halp!! thanks a lot!
help*
 
@DanieleC No problem, stop in tomorrow and hit up Bob or JourneymanGeek or DavidPostill or BenN if I'm not around
 
@allquicatic Eh. I know families of "mobile" people where the parents are the only people left in their home country
Mostly students/graduates. And pretty much everyone under 30 after brexit
 
8:21 PM
@kerbalspacecat :D
 
@kerbalspacecat Yeah, My sister lives in San Diago, another sister in the south of France, I was in NL and my mum on her own in the UK.
 
hey, a Britain with nothing but 50+ ppl will make it super hard for them to get "dem ritirement moneys"
 
All over 50
 
@allquicatic Maybe, or maybe they'll guilt their children into sending money home from abroad
Dunno how the brits deal with it but in Chinese families it's pretty traditional for the younger generation to send money home to support the parents.
Because there aint no pensions or nuffin
 
New AMD 300-series chipsets for socket AM4! tomshardware.com/news/…
 
8:29 PM
@bwDraco okay, so AM4 is new, but it's still 28nm for now?
 
@allquicatic It's not that new, but yes.
Upcoming Zen CPUs will be AM4, but so are current-gen Excavator CPUs
 
ahh
is the new mobo chipset being released going to support both existing CPUs and Zen?
 
> The AMD AM4 platform provides next gen I/O and peripheral support including PCIe Gen 3, USB 3.1 Gen 2, NVMe, and SATA Express. It also offers higher power efficiency than previous AMD desktop platforms (up to 70 per cent power used compared to AM3+). AMD says that the new HP and Lenovo designs featuring AM4 show the ecosystem's readiness for the upcoming high performance 'Summit Ridge' processors, based upon 'Zen' cores. AMD has a "commitment to support AM4 for years to come".
Last time I heard AMD commit to support my socket for "years to come" they ditched it less than one full generation later.
@allquicatic Yes
 
@kerbalspacecat What socket? AM3 chips will work in AM2 and AM2+ boards.
 
@allquicatic I will! thanks a lot again!
 
8:35 PM
Part of the reason behind AM4 is so AMD can amalgamate everything into one socket, for all their processors. Both the high-end ones and the low-end APUs are going to become AM4
 
Mar 28 at 2:27, by bwDraco
As noted before, all Zen desktop AMD processors will use Socket AM4. No more confusion with three different sockets (AM3+, FM2+, AM1) as before.
 
Wait Type: ASYNC_NETWORK_IO...

Translation: The moment you realized that you should have upgraded your aol dialup internet from AOL ultra version to the AOL titanium version.
That is how you database.
 
Dammit I need to re-learn how to database
Or rather how to architect a database from scratch
 
@kerbalspacecat for what purpose?
 
I got a complaint earlier saying a report was taking too long to run. And I gave them that response.
 
8:44 PM
@allquicatic mobile network signal readings
The service I used to use is getting slow and unreliable and takes about one minute per 1000 data points to show/filter it on a map. I have about 50,000 data points per network now :-/
So basically going to build my own Web service (and eventually mobile app) to visualise the data
 
@GuitarShoeDave Do people still use "Codd's Rules" these days? (you can tell when I last did any serious database design ...)
 
8:59 PM
!!wiki Codd's Rules
 
Codd's twelve rules are a set of thirteen rules (numbered zero to twelve) proposed by Edgar F. Codd, a pioneer of the relational model for databases, designed to define what is required from a database management system in order for it to be considered relational, i.e., a relational database management system (RDBMS). They are sometimes jokingly referred to as "Codd's Twelve Commandments". == Details == Codd produced these rules as part of a personal campaign to prevent the vision of the original relational database from being diluted, as database vendors scrambled in the early 1980s to repackage...
 
@CanadianLuke Yeah, I know what they are. My questions was do folks still use then when designing databases? Or have they been superseded by some newer wisdom?
 
@DavidPostill rules of normalization, sure, but I've never heard of them used as Codd's rules
and "over-normalizing" can be bad
 
@DavidPostill I had no idea what it was... I just know of normalization... And only 3 levels of it
 
also they don't apply to NoSQL databases generally
 
9:02 PM
@allquicatic Why not?
 
@DavidPostill because NoSQL databases aren't relational; they're usually key-value or object-based
 
@CanadianLuke Ah. I learnt them 30 years ago or something.
 
key-value is just a persistent hashmap, and the relationship between objects is defined by the object graph
rules about an RDBMS don't map well onto either of those paradigms
 
@allquicatic Gotcha.
 
> Rule 1: The information rule:

All information in a relational data base is represented explicitly at the logical level and in exactly one way — by values in tables.
yeah, k:v and object databases fail that rule right off the bat, by design, intentionally
and somehow they manage to work in production software all around the world

Grrr. Converting 3700 files with

Downlaod them... all the same. Whoops
steamer.gif -> $file
 
You can use PowerShell!
 
We can?
 
You can
 
I just uploaded them all to a BSD host, run imageMagic, and now downlaod them back
I guess it is a 'people use the tools they know' thing.
 
It can run any .NET assembly, like System.Drawing, which has a thing that can convert images
Add-Type -AssemblyName System.Drawing
dir *.gif | % {
  [System.Drawing.Bitmap]::FromFile($_.Name).Save($_.Name + '.jpg', 'jpeg')
}

@BenN nice little script
 
Thanks! PowerShell is pretty great
 
I wrote a fairly simple Excel spreadsheet manipulation script in VBScript, PowerShell and C# a few years back for work
the PowerShell version ended up being the most painful because of the automatic loop unrolling and figuring out how to make it not do that
the C# was the easiest
 
If I understand correctly, it shouldn't do that unless you explicitly do something to the collection that's not applicable to the collection as a whole
e.g. if you tried it in a PS version less than v3, it would fail, like (dir).Name
 
This got a bit out of hand:

0) Browse a webcomic (alexcartoon), starting from the first comic>
1) Failing to find a first button, image the repagination plugin to get all comic on one page (3755 images plus headers etc)>
2) Save do disk
3) Play with the 26MB .html file, decide that you might as well use the photoviewer>
4) Find out that windows photoviever does not zoom. At least not with these gifs. Worked when converted to PNG, JPEG etc, just not at gif
5) Upload to a BSD host and convert to JPG
A never ending story.

Q: Lenovo IdeaPad Flex 14 leaking sticky gel

lovely coveOur Lenovo laptop, which was manufactured on 2013/08/25, started leaking a clear gel from the lower right hand corner of the screen. Other than being messy, it does not appear to have any effect on the performance of the device. Any suggestion on what is causing this and if so what can be done ...

That's new.
