2:00 PM

Or maybe with 21,000 hours on the backlight it's just time to replace it :-/

I need to go read those piston reviews.

I'm not sure whether I should be doing it in bed, in the living room, at my desk, or on the bus.

Journeyman Geek

also that top monitor is awesome ;p

That's a neat idea, space ship feelz ;p

Journeyman Geek

2:16 PM

looks like he has a loft bed too

@qasdfdsaq No messier than mine... I think

:S

Journeyman Geek

lol

I don't have the excuse that I'm working on stuff either

I have to use the living room table for soldering

Speaking of which, I really need to clear this out

there's a stack of letters on the left -_-

@Bob Did the letters fall off your keyboards or out of your monitors? ;)

@DavidPostill Both? :P

Journeyman Geek

2:28 PM

hands @Bob duck tape

@JourneymanGeek ...*throws onto duct tape pile*

@JourneymanGeek Haha, thanks. Its a crappy old VGA TN though, and is the sole reason i still need a graphics card that outputs analogue

@JourneymanGeek Yeah, tiny room, not enough space.

wait, is that one of those lab stands? o.O

Derp.

Q: Can the A380 ferry an extra engine, like the 747?

A useful little quirk about the 747 is that it can ferry a fifth engine on the wing, for when another aircraft is stranded somewhere in the world. Does the A380 have the same capability? If not, how would an airline manage an aircraft needing a new engine whilst away from a maintenance base?

engine-failure boeing-747 airbus-a380 ferry-flight

Also, Dell seems to have missed the "Consumer" part. This is clearly a top of the range professional mpnotor.

2:39 PM

waiiit since when did dell do oled?

@Bob Since today.

Journeyman Geek

@Bob considering its the same 4-5 companies that make panels for everyone

@Bob The whole point of an A380 is the amount of space inside the plane...

Using it to externally carry an engine would be pretty dumb. Also an A340 could do it cheaper.

Journeyman Geek

They probably got on the phone with LG, ordered a few hundred thousand grade A+ 30 inch OLEDs and got to work

@qasdfdsaq Well, the weight capacity helps. Not just the space.

DAB+ radios are expensive :\

2:48 PM

More on the new AMD Wraith thermal solution: pcworld.com/article/3019993/ces/…

Should ship standard with high-end AMD processors.

Heh. AMD is flaunting their new cooler, while Intel doesn't bother including one -_-

AMD stock coolers have proven to be notoriously noisy in the past. This should be the end of these complaints.

Hmm... local supermarket has $3.75 BT speakers.

I wonder how shitty they are.

Journeyman Geek

lol

@Bob The one I have (HMDX Jam Plus) ran me $30.

Journeyman Geek

2:52 PM

@Bob how bad could they be?

@JourneymanGeek I don't know if too quiet or ear-bleedingly poor would be worse.

I think my benchmark for "uselessly bad" would be if it were as bad as the built-in phone speaker.

20 hours ago, by bwDraco

AMD has had a history of complaints with noisy stock CPU coolers. This should silence (ha) those complaints.

@bwDraco shrug I picked up an x100. About the same price.

Journeyman Geek

@bwDraco the best stock cpu coolers won't be much use without a compelling product range

That was a while back.

2:54 PM

@Bob Well they've not got much else to flaunt right now...

I mgiht look into getting a better one soon.

Journeyman Geek

@PatoSáinz chat.stackexchange.com/transcript/message/26661958#26661958

But I don't care much for max volume.

@JourneymanGeek Well, AMD has significant new products on the horizon.

Journeyman Geek

@Bob also intel's stock coolers have essentially just been the same base design and shrunk since the late PIVs

2:54 PM

@Bob The £5 ones I got in my local supermarket were actually pretty good.

Journeyman Geek

@bwDraco vaporware until they come out

@qasdfdsaq Hm. I might have to check if the local one has them in stock tomorrow.

Worst case I can laugh/rant at/about it and then take it apart.

So good that I used one as my main speaker for 9 mpnths last year

@JourneymanGeek They apparently shrunk too far and now they can't find them.

The best air-based thermal solution Intel has right now is the TS15A.

2:56 PM

@Bob lol no

Then again, Intel is no longer shipping any thermal solution at all with their high-end processors.

It's really only the top of the range overclocking SKUs that don't come with stock coolers.

Journeyman Geek

lol

@qasdfdsaq 'twas a joke :(

And that's pretty sensible since no high-end overclockers would ever seriously use the stock cooler.

The rest of them... the shrinking isn't too bad actually. The average TDPs have gone down too.

Journeyman Geek

2:57 PM

yup

Nowadays, the maximum TDP of their mainstream line is 65w, compared to 95-130w previously.

Hmm.

Vodafone is doing a $3 for 2 GB data for 24 hours.

Journeyman Geek

yup

That's actually not bad.

I for once didn't spend a penny on roaming calls or data while I was abroad :-D Singapore and Thailand have such good prepaid/visitor mobile deals :-/

3:01 PM

The TS15A is rated for 130W (Wraith is specified for 125W) but AMD seems to be using a larger fan than what is on the TS15A which should mean lower noise.

Journeyman Geek

@bwDraco intel does use a very different/simpler hs design to this

the wraith looks a lot like a decent third party, low end cooler. Intel's just a solid slug of copper, with a aluminium jacket.

Its crude but effective ;p

Airbus Beluga XL

The Airbus Beluga XL is a planned large transport aircraft based on the A330-200 airliner, to be the successor to the Airbus Beluga. The XL has an extension on the fuselage top like the Beluga. It is being designed, built and will be operated by Airbus to move oversized aircraft parts. The program was launched in November 2014 to build five aircraft, with 30% more capacity than the existing five Belugas. It will be able to carry two A350 XWB wings instead of one. The design freeze was announced on 16 September 2015, final assembly should start in 2017, and service should begin in 2019. The aircraft...

Whyyyyyyyyyyyyyyyyyyyyyyyyyy...

Journeyman Geek

why not?

The A330 is a fairly small, two-engine aircraft.

I'd have imagined using an A340 fuselage as the base would make more sense

Plus there's going to be considerably less demand for the A340 so there'll be unused capacity on those lines

Journeyman Geek

meh, they should make a drop nose 380 ;p

IIRC they wanted to do a cargo versuion but that got cancelled

3:07 PM

Yup. Lack of demand, and too much weight capacity

Maybe they wanted something more fuel efficient?

Also the A380 has an ugly as fuck drop nose already

Journeyman Geek

lol

its an airbus

they do not make pretty aircraft

the A380 is ugly compared to the old 747

I find the A320 series looks pretty nice

The A340 isn't exactly ugly either

Intel's design is a single large vapor chamber in the center of the unit, with metal fins extending from it and a fan on top. The AMD design is more traditional, with a series of heat pipes that nearly make direct contact with the CPU package.

3:09 PM

Ok. So we've had strangely heavy rain and floods for the last half week. And now there's a heatwave incoming...

And the A350 is weird, but in a futuristic kinda way, and not really bad

The TS15A is a very interesting cooler design. I don't recall anyone using a big vapor chamber in this fashion before.

4:00 PM

@JourneymanGeek Older Intel coolers, e.g. RTS2011AC, used a solid copper core. This was replaced with a vapor chamber ("heat column") in the TS13A, and the TS15A is an extension of this design.

The AMD Wraith seems to use a beefier fan (for lower noise) mated to a more traditional heatsink design with heatpipes.

This is the old HSF assembly AMD ships with their current CPUs.

hii

For starters, this looks like an 80mm fan. (TS15A uses a 90mm fan.)

4:23 PM

The AMD CPU heat spreader surface is just over 37mm square, for perspective.

So it looks like AMD is using a 100mm fan, which is the largest I've seen on a stock HSF unit.

Okay, the old AMD cooler is 92mm. If this new Wraith thermal solution uses a 120mm fan, I'd be impressed.

It's much, much larger than a typical stock thermal solution, in any case.

Podcast #70 - David Was Wrong And Jason Was Right

Abby T. Miller on January 7, 2016

Welcome to the Stack Exchange Podcast episode #70! Today's podcast is brought to you by the BB-8 droid. Today your hosts are joined by developer Jason Punyon, whom you may remember from way back in Podcast #21. Punyon works out of balmy Buffalo, NY. (Here's the Buffalo sentence they talk about for a weirdly long time.)

5:01 PM

It's possible AMD is using some nonstandard fan size, but whatever it is, it's much larger than what you'd normally find on a stock cooler.

@qasdfdsaq: I enjoy the C5 Galaxy

this is going to be an enormous year for high-end consumer (gaming) tech

AMD Polaris, Nvidia Pascal, both 14/16nm FinFET; and 4 TB Samsung 850 EVO / 850 Pro models hitting shelves in late Q2 / Q3 2016

Grr. Home. But neighbours are not home

I want my damn PC!

I am still tempted to go for a samsung 951 NVMe

Probably 256GB since that is afforable as OS drive

But first I get to play with the 1/3rd price, same capacity slow as a dog SSD.

At least if I ever caputure my neighbour at home, so I can pick up my posted package

5:40 PM

linipc.com/blogs/news/…

Passive cooling thermal solution for M.2 SSDs

Controller throttling shouldn't be a major issue in most consumer use cases, but heavy workloads can cause the drive to overheat.

Maximum temperature rating is 70 °C (which is typical for most SSDs); throttling occurs at about 75 °C.

Even SATA SSDs have it easier because they can use the case of the drive for passive cooling (most SATA SSDs have a heat pad between the controller and the case).

Aye. I am a simple user

Std coolong should suffice. As will PCI-e 3 x4

But first I want to see if the 1/3 rd price SSD (BX200) feels as fast in most user scenarios

And play some with ESXi (aka vmsphere), UEFI (never used any firmware but BIOS, suns and alfa's) and see how wel lPCI-e passthough works for GPU's

Sadly that might be tested with NVidia, which has a less then nice IOMMU for gforce cards. I might need AMD for that

@Hennes The BX200 will feel much slower than any PCIe SSD, let alone one that uses NVMe.

Aye

BUt 1/3rd of its price

In fact, the BX200 is noticeably slower than most SATA SSDs.

I am willing to test of BX200 for OS and proper SSD for work data works.
or if I should banish the BX200 (worst case it will replace a 300GB WD black which fails unless I connect 2 USB ports

5:53 PM

Latency and IOPS at low queue depth are the main determinant of storage responsiveness in consumer environments.

The BX200's power usafge is very high for an SSD, but it shoukd feel at home with single USB2 connection

The BX200 has a small SLC cache

Not sure how well that will work out

But willing to test

Worst case, Eur 67 down for a 240GB drive

@Hennes Unlike the BX100, however, it's built on TLC NAND. That is not ideal for workloads that are even remotely heavy (unless it also uses 3D NAND; see Samsung SSD 850 EVO).

Aye

I read the reviews

For sustained it truly sucks

But for an OS drive. No idea yet

...and there is no getting around the fact that TLC is slow—although once again, Samsung's 3D TLC NAND implementation does not suffer as much especially at higher capacities.

(The 250 GB version of the Samsung SSD 850 EVO is rated for 300 MB/s write speed once the TurboWrite cache is exhausted.)

Right now I want a play station to test ESXi, win10, win7 and VT-d and similar as yet untested stuff

5:58 PM

The BX200 drops to less than HDD speeds (75 MB/s) once the cache is full.

user image

Left: 480 GB version. Right: 960 GB version.

Image credit PC World: pcworld.com/article/3000913/storage/…

Afterwards I might add 2x2TB (mirror) as main storage, 1x 1TB SSD and a 951 as OS disk to get a main new desktop.
And possibly move my gForce 960 for graphics,
While keeping the old X58/i7-920/ RAID with 4x1TB RAID 5 as backup system

Absolutely not ideal for heavy workloads.

Again, I'd recommend the SSD 850 EVO for everyday users.

But regardless of what I choose. I play desktop, one work desktop

And yes, 951 NVMe is overkill. I know

I have the SSD 850 PRO, which uses 3D MLC NAND with very high endurance. It was very expensive when I got it for Christmas 2014 (we paid $350 for it) but it's pretty much the best SATA SSD you can get.

The 850 PRO is ideal for workstation users looking for reliable storage with excellent all-round in any workload, light or heavy, random or sequential. It's much cheaper than PCIe SSDs these days, even if it can't match their performance.

It's also available in very high capacities, up to 2 TB, with a 4 TB version to be released later this year.

My current replacement cycle is 6 years. So it should last that long

6:11 PM

Mine is 512 GB, by the way.

I'd recommend 256 GB for everyday users and 512 GB or 1 TB for power users (depending on whether you have large applications such as games and/or a mechanical hard disk for bulk data storage).

128 GB is marginal for modern systems and should only be considered if you have a very limited budget. It's also not the best value as cost per GB is considerably higher on very small drives.

@bwDraco Many SSDs do this, but the variable is how much writing it can endure before it starts to bottleneck.

@allquixotic That only happens with TLC NAND.

TLC NAND drives use a simulated SLC cache to try to make up for slow write performance in typical consumer use cases. Once that cache is exhausted, however, you wind up seeing the slow performance of the TLC.

Samsung has a better time handling this because they use TLC in conjunction with 3D V-NAND but it's still slower than MLC NAND (3D V-NAND or otherwise).

anyone found an internal 2.5" 4 TB laptop HDD for sale?

6:27 PM

@allquixotic Nope. That kind of density is not yet possible with mechanical hard drives.

The Samsung 2 TB SSDs have a 7mm z-height, which means that SSD storage density has already exceeded that of hard drives.

@bwDraco Not true; there are 4 TB 2.5" HDDs available in an external hard drive form factor. If you have the right tools, you can rip it out of the enclosure. I was looking to not have to do that.

@allquixotic Well, those drives are 15mm z-height. They will not fit in a laptop.

@bwDraco oh, okay.

I'm betting the first 4 TB anything that fits in a laptop will be an SSD, then

and it's coming this year

The underlying Samsung Spinpoint M10P disks are 5-platter.

sigh

Gotta replace the cyan cartridge on my printer soon, it's down to 2%.

Note that I always have a full set of cartridges on hand so this isn't really an issue but replacing a cartridge always involves a full cleaning cycle.

The cartridges are not cheap ($30 for C/M/Y, $35 for K) but the yields are decent at 1050 pages each.

This is a SOHO-grade printer. Cheaper consumer-grade printers are generally much worse.

6:43 PM

Both new hard drives arrived. Mirroring the first drive over, accepting that some backup data from November won't make it

6:54 PM

At the low end of the spectrum, HP's cheapest Deskjet printers use type 61 cartridges. Yields are horrendous for the standard cartridges (190 black, 165 tri-color). High-yield cartridges are a bit better (480 black, 330 tri-color) but are $80 a set, much worse than the $125 a set for 1050 pages I'm getting.

Then again, HP printers with integrated-head cartridges tend to be more reliable than Epson printers with permanent heads in the occasional home printing use case. We've had HP 57 tri-color cartridges last years without clogging before they needed to be replaced.

Epson printers are more economical for heavier usage.

7:30 PM

anyone know how to serve IPython/Jupyter notebooks or slides using nginx?

I'm banging my head against the wall trying to get them to work properly... but I can't seem to get it to work

8:02 PM

Just saw a feral cat chase after a squirrel first-hand, and it was in our neighbor's backyard :p

Who won the chase?

Squirrel seems to have gotten away.

Can't say for sure, though.

8:32 PM

This trend towards TLC SSDs is not a good one. TLC NAND has poor endurance (1000 cycles or less) and while SLC caching helps, the SSD will dramatically slow down once the cache is exhausted.

Samsung is able to mitigate the effects of this very well because of their 3D V-NAND technology, but everyone else is having trouble keeping up.

pcworld.com/article/2947864/storage/…

pcworld.com/article/2993875/…

PC World's Jon L. Jacobi is a huge critic of these TLC drives.

> the TLC is slow, and there’s not nearly enough SLC cache to maintain performance during even modestly large file transfers

...and there are use cases in a consumer environment where this will be an issue.

The 120 GB Samsung SSD 850 EVO is not immune to this issue (it drops to 150 MB/s once the SLC cache is exhausted). However, the 250 GB and larger models are much less prone to this kind of slowdown due to larger caches and the underlying 3D V-NAND is faster even though it is TLC (250GB model: 300 MB/s after TurboWrite is exhausted).

anandtech.com/show/8747/samsung-ssd-850-evo-review/2

Samsung's implementation still suffers from a small cache but they have better NAND (and smarter controllers) which means the impact of exhausting the SLC cache is nowhere near as noticeable.

8:58 PM

sigh

Alas, the best option is to keep flagging. Maybe post a MSE post about this. Also, oneboxed spam makes me sad.

@CanadianLuke, are you able to delete or edit that message?

Which one?

@bwDraco @CanadianLuke It's gone. I flagged as spam (not enough) then use my super delete option. I guess 3 deletes were enough.

@bwDraco I know ;)

@bwDraco Meh, Samsung had a 1 year lead on V-Nand but everyone else has caught up now

9:10 PM

@qasdfdsaq Not yet. There are no finished 3D NAND products from anyone other than Samsung

Apr 27 '15 at 5:01, by DragonLord

@JourneymanGeek From the looks of it, Samsung is an entire year ahead of IMFT and Toshiba on 3D NAND.

IMFT has focused on a fundamentally different non-volatile solid-state storage technology called 3D XPoint.

Err Intel has been shipping finished products for a year

@qasdfdsaq That's just NAND chips. I have yet to see an actual, finished SSD that uses IMFT 3D NAND.

Not even an enterprise drive.

He'll have the account until a mod on a site he's signed up for has manually destroyed him. I don't know if it's network wide without a community mod, though

The first consumer 3D NAND SSD, the Samsung SSD 850 PRO, was announced on July 1, 2014.

Samsung is at least 18 months ahead of everyone else to a finished 3D NAND product.

9:51 PM

Quick photography question.

Today's compact cameras have more sensor resolution than ever but it seems that resolution is never really attained.

With slow lenses (leading to diffraction limiting) and high noise even at base ISO means, I'm getting the feeling that more pixels are not worth the extra storage.

@CanadianLuke Thanks for the explanation ;)

(Of course, this is not the case for large-sensor cameras like DSLRs where every pixel is much larger.)

So, on my Nikon COOLPIX S9900, should I drop to 8 MP or continue to shoot in 16 MP mode?

Welcome

Hi!

@bwDraco iirc changing the resolution is tell the camera to save a scaled-down version to the memory card (i.e. the sensor still captures the full 16MP and then rescales it before saving)

10:01 PM

@nc4pk The issue is that there's not much more information available from the sensor from 8MP to 16MP.

Could anyone recommend a command to run to generate enough entropy for gpg on a Debian server?

right, the only potential pitfall of shooting in 8 MP is that Nikon might be using a fast (as opposed to higher quality) scaling algorithm

there's not much additional detail but you might be losing detail because of the scaling

if the camera didn't rescale (i.e. only captured data from, say, every other pixel) then there'd be little downside with shooting only in 8MP

@bilbo_pingouin What are you trying to accomplish?

...or better yet, pixel-bins (e.g. Nokia 808 PureView)

@CanadianLuke generate a gpg key... which requires some entropy, but now I seem to have made it

10:09 PM
