Why are PC sales declining ? (Skybuck thoughts on it too)

Ok,

Yesterday I saw it and played with it...

It was quite an amazing experience.

None the less it remains somewhat of a toy device.

What irritated and annoyed me the most is the way the scrolling is down.

The fingers have to glide over the screen, and if one is not carefull it
might activate
a button.

What also irritated me is that there is only a backward button and not a
forward button.

If I want to return back to were I was that's not possible. I would have to
restart the play store
for example which is very annoying.

Also it's very sensitive... all kinds of buttons will be activated... also
menus in the weirdest places
it's not really centralized at any spot... will be difficult to learn and
remember where all the menus
are located.

Also the device shuts off real fast, and it seems to have some problems with
the lightning of it...
it goes dark... and then bright again... kinda weird.

The device shuts off in like 5 seconds or something... this can probably be
changed.

I also looked at the software... it's mediocre here and there... it reminds
me of my ms-dos days when I wrote all kinds
of crappy little programs.... this is just like that... all kinds of
neato/crappy apps... there are probably also some nice
apps... my mam is way too scared to download anything... so I didnt download
anything.

There were some slightly interesting games but nothing to exciting, also
somewhat mediocre.

I am kinda surprised that this device is already 2 years old... so it seems
they sold her an older one ?

It still looks fancy pancy... I wonder what the latest and greatest is ?


Android will sure give Microsoft a run for it's money... for now I am not
too worried...

I haven't really seen windows 8 yet on a tablet... have seen it in virtual
machine...

Maybe windows blue will make short work of android... time will tell

Androad did run extremely fast though, everything was butter smooth, except
for the occasional video
download, that sometimes failed and the device shutdown.

Flash was also not available kinda weird.

Perhaps this model is a bit older and perhaps it's solved in newer version
me dont know, maybe not.

It costed 500 euro or so with 50 euro cut or so.

I ask here about the warranty period she didnt ask

Probably dont matter... it will probably die a few days after warranty
expires as usual

Though it didn't seem to run hot.. and it made zero noise...

It was a nice experience.... but for me being used to big LCD screens... and
a nice big keyboard and mouse... I'll stick with that

Also I like scrollbars way too much ! =D

The pinching and widening to resize pictures was fun...

The sound of the device kinda amazed me... I read before I went over
there... in the specs... that it had surround sound...

I was wondering how such a flat device could achieve that... the sound was
indeed impressive for a flat little thing.

But ofcourse it pales compared to my x-fi + 7.1 surround sound system (even
without the subwoofer) lol.

I don't have wireless internet so for me a tablet makes little sense in that
sense

Unless I want to keep it a little bit more secure... but it's probably not
really secure... it could end up on random wifi networks.

Though sometimes I wish I had one too for in bed... then I can be lazy in
bed

I will wait and see if any windows blue arm tablets arrive... me kinda fan
of microsoft/windows... that's what I know...

That android thing could kinda drive me crazy with all it's weird quircks...
but for newcomers they probably dont mind as much.

The way it swept the screen/menus was kinda fun to look at but not very
convienent hard to find things.

So it's all flashy and eye candy... but little real practical
value/handyness and that kills it for me mostly

Though the integrated deeper menus did show some sense and ordering... and
that was more okish

The screen was super reflective like a mirror... I could see myself when the
screen went black... it wasn't very pleasent to look at... though I am a
handsome guy :P* =D

I like looking at myself... but not when I am trying to look at the screen
lol.

Also the button to take a picture of yourself seems quite annoying... I
offered my mom to remove it... but I am not even sure if it's possible I
would think so...

Also setting before so many cameras makes me feel slightly uneasy.

Plus the added radiation of all that wireless traffic makes me wonder about
liver cancer and all that =D the final crazy nail in the coffin

Plus also wireless interception/hacks and cracks...

I asker her if she was going to bank with it... she said no... I thought
that was kinda weird.. cause she would do it with the bigger laptop.

I can see her point/argument though... the tablet is more convenient to
quickly catch up with some stuff... she seems to like facebook the most...
watching new pictures of family members and acquintences. I saw some
interesting photos as well, but mostly it bores me.

As a software developer I found watching at the stores the most interesting


I took a look at the software development stack needed, it's quite
large/immense... and it uses java for ****s sake ?

Though in a few days Delphi XE 4 is coming out and it might have android
support...

Would be fun to make a stupid little app/hello world for my mother's android
device

Maybe more but dont count on it... probably not a lot of money being made
with it... but that depends on what you call a lot and which store
service one uses.

I have seen stories of cap limits of 30k perhaps 5k per year... also 1m per
month ad stories - crazy/angry birds anybody ? LOL.

What ****es me off is that most of this technology does not seem available
for PCs ?!

Can I please have some of this embedded into a PC ?!

Thanks ?!

Perhaps that's a pie dream for now... driving big LCDs requires a bit
more...

I don't really believe that though... I think it's already possible...
something is ****ed up... too hot processors for desktops... need more cool
ones =D

Bye,
Skybuck.

You got that wrong, the Titan video card was named after the

So it's the graphics card that probably gives it the most of it's processing

However one would have to make sure the power supply can handle it and

The titan probably gets hot though, so a passively cooled graphics card is
interesting too though they not as powerfull.

Perhaps a mid range card is safest.

Also a good case is needed for ventilation.

You mentioned upgrading an old desktop and then you mention buying a new one

I am a bit confused about that.

If truely upgrading have to be carefull that all components can handle it..

If buying a new one, perhaps being a computer from a specialized gaming rig
company is an idea.

Perhaps they can throw it some nice water cooling... or just a decently
designed air cooled PC.

It all depends on the budget

Minecraft is probably not the most demanding game but you also mentioned
overheat of laptop... so you are familiar with the overheat topic

Dell is probably crap, HP is probably crap too... a little bit less crap
though just cheap... at least my mothers HP still running barely... it
little used though... my sister bought a Dell it died

All computers seem to die lately

1.) should I buy from Dell? *(I've used them in the past.)

If you lazy perhaps yes, or give Alien Ware a try or so - they
selling gaming rigs if I am not mistaken

2.) Which operating system. *I was thinking of win8... but now you've
all made me nervous, but I wouold like some newer version of windows
(running XP at home and work.) moslty becasue the kids will be using
the newer version in school. *So maybe Win7?

Perhaps wait a bit for the new windows 8.1 operating system.

It would suck having to buy windows 7 with all those services packs and
patches... it would be patching 2 days at least.

Also it's on the way out so not really future ready ?! More and more games
will start focussing on windows 8...

3.) How much memory? I figured 8 or 12G.

It's a bit overkill but always good to have more.

Even my system with 4 GB ram only uses 3.2 and it works fine.

If you want to be future proof get 8GB otherwise spent the money on
something else.

4.) Do I need the fancy graphics cards for gaming? *(My thought was I
could let my son pitch in for a better card if that's needed.)

Yes for good gaming a graphics card is needed/essential.

I see more and more games using CUDA, so getting an NVIDIA card would be
wise plus I am a slight nvidia fan so I may be biased

I hope to have been of some help, trust me it not easy

Thanks Skybuck, At the moment I'm eyeing an older machine here at
work. Maybe I can just upgrade to a better video card for my son.
It'd be useful for him to get his head inside hardware of a computer

If you're going to use Windows 7 or Windows 8, there should be
a downloadable "Upgrade Assistant" or "Upgrade Advisor", which
will note any issues. These generally require some version of
..NET to be installed, so if they don't run, that would be
the reason.

W7UpgradeAdvisor (to check existing apps).
"make sure .NET Framework 2.0 is installed..."

http://www.microsoft.com/en-us/downl...ion.aspx?id=20

Checking whether W8 will work. Not sure what version of .NET
this one needs. (Programs without .NET detection, die with a
"mscoree" dependency, for software that is too dumb to check.)

http://windows.microsoft.com/en-US/w...e-to-windows-8

To run Win8 x32 or x64, first, you need a processor of the
appropriate instruction set. If you wanted to run the x64 version
(machine has more than 4GB installed), then the processor would
have to support the x64 instructions. (Microsoft doesn't allow
desktop OSes to use PAE in a way that extends past 4GB, for program
usage. Only drivers can use PAE on x32, above 4GB.)

The next requirement for Win8, is the CPU must support NX/XD.
That means the processor must be more modern, than the last P4
processors they'd made. The P4 I have, doesn't have XD, so I
can't run Windows 8. I could probably run Windows 7 x32 on it.
On the AMD side, probably an S939, AM2 or later would be OK.
The advisor software from Microsoft should be able to figure this
out.

If you had some old P3 machine, then that probably wouldn't be
a good candidate.

Windows 7 could benefit from having around 2GB of memory. That
would be a comfortable starting point. It will run on less than
that, but with slight performance impact. More than 2GB, you'd
probably be better off with an x64 OS.

An x64 OS install, won't run 16 bit software. That might include
the installer from some of the older games. If you have some
crusty old games in your collection, that might be a potential
issue with an x64 OS install. If the games are 2013 releases,
there should not be a problem.

My old Q6600 benchmarks at 2962 and uses ~350W with graphics card
whereas the new i7-3770K benchmarks at 9461 and about ~120W all in.

I can't say I've run any tests, but I don't see how they are getting

speculative execution should have been mature some 10 years ago. What
exactly is left to improve on?


Actual benchmark speeds are still increasing provided that you have the
right software and can use fully multicore and multithreaded code. The
problem is that after about 6 CPUs the law of diminishing returns sets
in and the code spends an increasing amount of its time sharing the load
between threads or worse still doing work in parallel that will later be
scrapped when the independent thread results are combined.

That assumption is a big one! The study I read said the turn was less
than 4 CPUs. Many apps just won't see much improvement with even two
processors. The observed increase in performance is because the OS
needs elbow room, so a second processor helps get it out of the way of
the user app.


These days the biggest performance increase can be had by putting
frequently used files onto an SSD with essentially zero seek time and a
transfer speed that maxes out SATA3. The Samsung 830 & now 840 drives
are very impressive - beware that some benchmarks give artificially high
performance figures of merit on highly compressible data.

The SSD upgrade is capable of giving old kit a new lease of life.

I'm taking a look at the combined drives now. I'm not going to pay an
arm and a leg for one. I can get a SSD for under $200 that is bigger
than what I have now. A combined drive should be close to $100 I am
thinking.


You can get the 256GB Samsung 840 for around £180 and the cheaper
consumer grade 250G one for ~£130. Provided that you keep it backed up
just in case the storage medium fails then what are you waiting for? The
prices may fall a bit more but the technology is available and the price
is not outrageous for the performance boost it offers.

I'm not sure I want to go that route. I need to weigh my options.
Also, I have some work to do for the next month or so and can't have any
down time. After that I'll look at this harder.

Most SSD's have such an algorithm and more. What it does is detect
errors, and reassign alternate blocks in its place. When access time
to any block on the drive is the same, such a system makes good sense.

Do they do that with rotating media? I have a problem with my laptop
where it occasionally looks like it is locked up. If I wait long enough
it returns. Usually it is one or two programs that stop, but if I try
to use other programs they can all end up halted. Eventually it returns
to normal operation. The cause seems to be a disk access that ties up
the interface without moving much data as indicated by the Resource
Monitor. The blue line maxes hard at 100% with a low erratic data rate.
When I looked up what the blue line is, it appears to be the disk
interface usage. This says to me the drive it trying to read a sector
which is bad and continues to reread it for some time before it either
gets the data correctly or finally fails.

I was ready to replace the drive at one point, but some of the files are
corrupted and the copy software throws up its hands and says, "What do
you want me to do about it?" I found my recovery disk but haven't taken
the time to fix the corrupted files yet. In the meantime, I've noticed
the SSDs are getting cheaper. This machine only has a 160 GB drive and
I can get a larger SSD replacement for under $200. I'm thinking this
will let me continue to use this machine for another year or two until
Windows 8 is acceptable.

I've always wondered why the hard drive or the OS doesn't automatically
take the bad sectors out of service. It's not like rotating media
doesn't develop problems with age.

Yes. Rotating media hard drives, have automatic sector sparing.
The long outages (up to fifteen seconds), are attempts at
automatic handling.

You should use HDTune, try the Health tab which shows S.M.A.R.T
statistics for the drive.

http://www.hdtune.com/files/hdtune_255.exe

The Data field of "Reallocated Sector Count" and
"Current Pending Sector", should be zero. If is is not,
and there is a significant number there, the Current
field will show remaining life, dialing down from 100%.

But you already know the drive needs to be replaced. Now,
things are bad enough, you need to copy the disk to another
disk, using the program listed at the bottom of this article.
It will scavenge sectors, and try and get as many sectors
off the original drive as possible. Then, you can run
CHKDSK on the copied drive, and hope for the best.

http://www.cgsecurity.org/wiki/Damaged_Hard_Disk

The procedure recommended, is a two pass copy...
You'd do this from a Linux LiveCD. The first pass,
gets as many sectors as possible, that aren't
complaining. The second pass, fills in the gaps.
I'd try getting "ddrescue" from the package manager,
rather than building it from source. But you could
probably do that, if you were motivated.

./ddrescue -n /dev/old_disk /dev/new_disk rescued.log
./ddrescue -r 1 /dev/old_disk /dev/new_disk rescued.log

If you wanted to, you could zero the target disk first,
before starting the copy. (new_disk is a placeholder for
/dev/hda, /dev/hdb, /dev/sda, or /dev/sdb or the like)

dd if=/dev/zero of=/dev/new_disk

Once you've done your best, and are happy with whatever
state is recorded in rescued.log, you could boot back
to Windows with the new disk, and run CHKDSK on it.

Before errored sectors start to show up, the disk is
patching out the bad ones, using the spares it has. It's
when the spares run out, that the problems start to
surface.

Twenty years ago it was hard into the performance limit curve. But that
was multi board level processors. The delay limits are relatively smaller
on chip and 8 way multi core is not as far around the diminishing returns
knee. Still memory bandwidth (even with today's huge multilevel caches)
is the fundamental limiting factor.

I was under the impression that modern drives not only take bad sectors
out of service, but attempt to copy failing sector to new locations
and transparently remap the storage location. This process might be
what your drive is doing when your system locks up.
