Amazon makes lot of money
There is no way you can get to $150B market vaue without earning money.
They have just been clever at dodging taxes around the world and move money into deparments with operating losses (aka heavy investments). so 150B/21Y ≃ 7B/Y. Not bad at all.
As long as the stockholders do not require dividends they can still keep the stock price high.
All multinationals have lots of advisors working on how to avoid taxes and give as little as possible back to the community. IBM probably have more financal acrobats than engineers.
Re: Good hardware but why not a real operating system? @AC
All recent Crays run Cray Linux Environment (CLE) it is a Centos/RHEL clone with extra tools and added drivers for proprietary hardware like their inteconnect and distributed memory model and a highly tuned kernel.
The hardware provides high bandwidth and low latency which makes it much simpler to scale out and share massive amount of memory in a single system image.
Could not find info if XC40 scales more than the SGI UV with 64TB and 2048 cores in a single system image.
You cant get those features on a commodity box with off the shelf interconnects.
What prevents vmware to add this feature to its hypervisor?. Seems like the simplest way to boost performance. Or just buy them up.
Opensource can do the job
You can now easily get 512GB in any server. You can then host native structures in memory/disk like Redis, Elastic Search, Hadoop. There is less need for an utterly expensive database system.
I have a >1Billion rows table where most of the collumns are not indexed. An unindexed table scan query in DB2 takes 20minutes (ZOS Mainframe), in Redis it takes 45sec(My workstation). the table uses ~55GB in memory and takes 4.5min to load initially. I only do simple queries for collumn statistics and variance for fraud scoring. But my workstation can now do this in 30minutes, while it may take 20hours on a IBM mainframe running DB2.
Re: RISC, not IRONIC
Risc64 has been around since 1994 with the introduction of R8000.
I was in university at that time, and was one of the lucky sods to run my code on the state of the art Silicon Graphics Power Challenge Array. Whow It flew! Around 8 times faster than the Wax I previously used. R8000 was the processor that skyrocked SGI into the hpc space.
Unfortunately the R10k and followers where not as good. Mainly because the complex superscalar pipeline was hard to upclock. I recall all the problems with getting the R10k above 195mhz. By that time the AMD opteron had arrived and the dark ages of Mips had started.
Great for governmental emergency networks
I do not think the average Joe is the target for this product.
It would be the governemental emergency network which most countries have. It is horrendously expensive to build, maintain, need special frequencies and special devices. With goTenna you can use your phone and just need an antenna to connect. Withing your entity (aka country) You can easily change the frequency into something reserved and legal.
Re: It's the "outsourcing megatrend" at work...
And we outsource all knowledge until there is nothing left. And no-one left to train new graduates.
Never ever going to buy any MS devices again
Bought a Surface pro2 for my wife. unfortunately it is so awkward to use, so she rather uses her old eepc. I tried to use it, but It is frustratingly unintuitive. Terrible process handling, apps not showing in desktop mode, desktop apps not showing in tablet mode. I do not blame the hardware, but the win8/8.1 OS trying to be both touch and desktop but ending up being neither. Anyone that have tried an android or apple tablet just laughs at it, when trying to navigate around. No wonder it became a mega flop. Someone responsible in MS management should be spanked/deported for letting this product survive through 2 disasters. Too much money in the pockets makes people lazy.
Game of subsidies
The subsidies are higher in Canada, The next sequel will be done in Montreal :-)
Moving all over the world, work long hours get well paid is great when you are young, free and single.
Not so great when You have married, mortgage up you ears and kids in school and kindergarten.
It's the same in most industries. It's a global marked. In Norway the oil companies get flat 78% tax refund on investments, Even the oil is here and not going anywhere, but it has helped infuse massive >$80Bill yearly investments into oil upstream and downstream technologies. Making Norway number one in oil technology in the world despite ridiculously high salaries. Making it hard for us poor sods in other businesses to attract local talent resulting in immigration, relocating or outsourcing.
My adventure into Cobol
I once worked on a project setting up batch jobs for data extraction from IBM mainframe (My project was a linux server working with that extracted data). My tools were an ancient EBCDIC terminal and large cobol programs that did extraction for other programs I had to copy and rewrite so it fitted my needs. And to test it I had to call a sysadmin with the program id and he would execute it. There were also another level, when I checked off the program as working. it was then run for some days on the test mainframe verifying it did not fuzz up actual work-loads and then moved to production queue on the production mainframe.
I've replaced some of them with 50 lines of very verbose perl. IBM provides an ancient perl(5.8.X) on their mainframes. It was quite fun to show some perl one-liners to the old cobol maestro. His comment: 'It is impossible to do a proper stacktrace on that, what if it fails". The perl code was never put on the production mainframe. They were afraid what another language would do to their production load. But it still resides on the test mainframe.
governmental control divide up the bastards
In a world where everybody can set up a web based sales channel it is a paradox that Amazon,Google and Apple have become so big players.I really believe the big three needs to be split up into smaller competing companies, like what was done with AT&T in 1992. Most countries have laws against monopolies and cartels. But how do to exercise it on a global scale. If you have more than a 20% market share maybe a tax should be enforced.

Learn yourselves a scripting language
Most dbas I know use scripting, but they are quite simple. Cant be compared to scripts written by devops that dont do anything else. A few days ago I was asked about license for Toad to a new developer. I told him we mainly use the basic command line tools and script in perl/bash/python/powershell what is needed. One of my recent jobs was a cleanout of a overpopulated database with severe lack of bufferspace. I had only a period from 1500to 2400 every day to run deletion and intervalls had to be less than 50k in each commit, otherwhise the production jobs just hanged. Had to add timestamp, scheduler and load monitor modules to the scripts (basic modules in our primary software) and now they run every night to clean data older than 3years and results older than 1 year. That way we can live with an undersized database. I'm a perl developer and added full perldoc with examples so anyone can easily port this to all the other databases we support. Most dbas would probably just use toad or any gui tools and do the job every month, or shut down production to do the cleaning in one go with far less sophisticated scripts. So learn a widely awailable scripting language very well and use it all the time.
Please continue truecrypt
Truecrypt working fine on both linux and windows. I've never had any issues with it. Just making sure I have backups and keep my keys safe. But my new laptop with bitlocker is horrendously slow. encryption should be OS agnostic by a third party company.
Re: Meh... - steam on linux
"Once Linux can support my Steam games my Win7 install will be zapped and I'll be running my Linux distro full-time."
The only games I've got working on Steam Linux are Half-life2 and Portal2, only Valves own game.
And it was a bloody nightmare. I had lots of files missing I had to probe around the internet and on my original dvds to find. But it was good error messages. Maybe my problem is that I run OpenSuse. Friends with Ubuntu says it works much better.
Install activestate perl and with the ppm (perl package manager) you can install around 8000 packages for windows or build your own. It's completely integrated.
"- And the people who are too dumb to install anything, and too dumb to update their subscriptions. They now think that a virus-riddled machine is the normal state of affairs. It isn't even worth the virus writers targeting these people any more."
I'm in a forth camp:
Those who have a company locked down laptop with Norton Antivirus 2014, bitlocker and other craps. On my 3year old Opensuse 13.1 host laptop cloning a 10GB vm took 25sec, on my shiny new laptop it takes 5minutes. It is the same .vmx file. faster drive better cpu.
They should rather invest in new businesses than sharing out dividends. When your turnover sinks like Itanic and your balance gets deeper in the red for every quarter it doesnt look good giving out dividends. Why not use it to subsidies a really dead cheap Iphone/Galaxy killer. A S5 specalike with a 42MPixel camera for $100. I believe you would really get quite a markedshare then.
Re: @AC, whatever. (was: whatever.) @h4rm0ny
"..CentOS, on the other hand, is based on stable Red Hat releases so - whilst not as newbie-friendly as Ubuntu - is at least stable and predictable."
Centos Great. but _NEVER_ use Oracle Linux. Big money corporations exploiting opensource.
This only makes Redhat add more features as close source making it out of reach for CentOS.
Re: @AC, whatever. (was: whatever.) @h4rm0ny
>OpenSUSE appears to be a little media unfriendly, although does tick the box for support.
In order to remain true opensource the base distro do not contain any closed source files:
It puzzles me why this can't be a checkbox - aka 'Add non free,open multimedia codecs' in the base installer. It is easy once You know how, but first time users do not have this knowledge and once the mp3 does not play and the mp4 does not play, they reject opensuse for something else.
This is nothing new
Sgi did this with Oracle and Informix back in the nineties. The only issue was the horrendously priced memory. 4TB sat you back several million Usd, and you could at that time max get 8GB per 2xR10K nodeboard, so you needed 1024cpus to drive the memory. SGI. sold several 32 and 64 cpu configs with maxed memory just to run shmem in memory databases.
Re: Nice place
>It was clearly utter shite, and never going to happen.
>MB/MQ is rock solid mature tech that 'just works'. customer love it.
MQ is really good, but its pricetag makes it out of reach for most projects. Software like Apache's ActiveMQ is comming of age and you can use it for IPC queues. Something I've always wanted to do with MQ, but it requires the expensive MQmanager.
I bought my wife a surface pro2 because I got an offer I could not refuse. but unfortunately she's not using it. she rather use an old netbook with XP.
The worst thing is the desktop and the apps do not talk to each other.
I have to use the processlist to kill apps that do not show on the desktop, and it is a resource hog.
Better buy a standard laptop with win7. I've lost the word icon for the apps, it is in the desktop but not showing anywhere as an app.
I have to read a book just to learn the basics, that is not needed with any other 'modern' OS.
I run opensuse on arm on an old asus transporter T300 and it is way more mature than win81 touch.
In 1997 had a Toshiba Libretto, it was smaller than the EEEpc 701 I bought 10 years later had a tiny 640x480 screen Pentium166MHz, 32MB Ram, 2GB fast(at that time) HD, full windows95 and around 800g. The keyboard was excellent.
I loved it. would have loved to see a computer today with the same form-factor.
Cloud hyperscale growth
"The additional growth in ODM Direct sales, spurred most recently by a native data centre expansion by some of the largest device providers, will help the server market reach that tipping point faster,"
If you need 20K identical commodity boxes/year you can just set up your own production than buying it from the likes of Dell.
Re: What the hell did they expect?
"And how did Linux approach this? Linux's approach shows it doesn't matter if MS had performed as well as Linux, since Linux isn't taking over the desktop marketplace."
The challenge is that most people find their current desktop just as good and do not want to upgrade.
This is what happens when software becomes mature. Then you switch to yearly licensing instead of a one time purchase.
Apple Cube 2
Recall the Apple Cube from 2000. Also a very nice design, but the premium price made it fail. There were also some issues about overheating because it was fanless. And the performance was not that good.
I do not care about the design of my box. it is performance and noise that counts.
I like to hide the box in a closet somewhere out of sight.
Re: I keep looking at these NAS devices
If you want to have all the features a typical SMB-level NAS has, that'll be a six hours chargeable time to have it in a turnkey state for the user - maybe two or three if you are only throwing SMB, NFS, SMTP, an intelligent UPS on it, including installation.
Most linux distros have this preconfigured, you only have to turn on some systemd/chkconfig flags and enable some filesystem. On opensuse it takes a few minutes to format disks and configure samba and nfs. What I hate though is their apache configuration with 20+ different files.
What I really like is webyast with makes you configure the entire server via web,
Fortran with openMP
I've not written much fortran code, but I've benchmarked it and parallelized it using openMP.
As long as you could identify the serial and parallell part and assured no variable dependencies outside of the parallel part it was just to use the openmp pragmas. worked like a dream.
!some OMP pragmas I've forgotten:-)

vmware and centos makes my day
CentOS6 is the best host. Linux has way better firewall and routing capabilities with route, openvpn and ipsec. I've had all problems with routing when using windows as host. And it is 100% compliant with RHEL so all commercial linux software supports it. It also do not have the dreaded systemd (yet).
I develop commercial software used by banks/processors requiring me to log into their systems via all kinds of vpn software and citrix. I mostly use windows xp as the guest for it. some of the guests have failed when running on a windows host, but never on a linux host.
Our software is cluster based so I have lots of centos5/6 guests with dhcp along with database servers (DB2/Oracle express ) and websphere MQ guests for delivery. I use the express editions because they are compliant with the enterprise editions but I do not have to care about the licensing and lower requirements, so copying vm-images around has never been easier. I keep separate guest-vms for each customer emulating their setup. this way I can build rpms that require just a stop of application, rpm -Uvh new package and start. (usually 20sec) in production.
When it comes to the virtualization I use vmware workstation9, it works fine with the rhel6 kernel and everything works. even hwrendering (I use the binary nvidia drivers on the host) of windows games like skyrim on win7 guests works excellent.
Years ago I used the vmware server v2, and afterwards I was forced to use Xen and virtual box. (didn't want to pay for linux software) they work fine for stuff that do not requite performance. Our software is 25%-50% faster on a vmware guest compared to virtual box guest. So it is a very easy decision to use $179 for a vmware license. vmware handles io _WAY_ better than xen and virtual box.
Personally I love opensuse, but their upgrade policy makes me have to reinstall every time there is a new relase, so I have some opensuse12.3 and 13.1 guests I build and run our software on to make sure it works. with CentOS it is just yum update(ex: to upgrade from 6.4 to 6.5)
and all your binaries still works.
I've created startup scripts which starts my database and websphere MQ guests automatically on reboot. I have a samba share on the host I share among all the guest.
Here I have the source build and release directories and a webserver so I can get hold of all the software nomatter if the guests are down and I'm on a customer vpn guest and need to install software built on an other guest that now is down.
Every guests except the database ones I keep under 20GB in size, that way makes it very easy to backup and move around to other vmware instances like my laptop, home computer or to ESX/vsphere servers. I have base guest images with the base software requirements so designing for a new scenario is just a clone away (with SSD cloning 20GB takes 20sec).
Earlier I used to have several noisy boxes under my desk. they are now all in a single almost silent workstation. I have around 30 different virtual machines where up to 8 running at the same time on a 32GB Intel i74770 512GB SSD with a /shared sata disk of 2TB.
>Brit upstart ARM for a pittance, for example.
AFAIK ARM has been around since 1985, A very slow upstart to say the least. I believe they have licensed IP cores since atleas 1992.
We develop on CentOS, customers buy RHEL
All our customers run RHEL but we develop and build rpms on CentOS. It is binary compatible no need for compilers etc. Many critical systems are not allowed to have compilers installed. This works like a dream and we do not have to buy expensive RHEL licenses.
Another issue is that Opensuse and Fedora changes way too often. CentOS 5.0 was released in 2000 and I've still just 'Yum update' it up to CentOS5.10 without any problems. That is almost 13 years of patching the same binary compatible linux system. Impressive.
I've always hoped someone would do the same with Suse Enterprise. Which I consider being superior to RHEL. But their licensing is 60 day trial. No access to the patch and update service after that. It is just too much job when you have 30-40 vms lying around. Running all kinds of strange instances you might need.
Old legacy software You may suddely be paid to update and then you have to reinstall just to get the latest patches.
"bare sorgen" is a norwegian saying meaning everything is just shit and cant be worse.
I bet the hardware vendors are happy - not
Revenue but not much margin:
I knew IBM had problems with their SmartCloud when they bought SoftLayer. Amazons S3 is way much more advanced and feature rich it is like vmware ESX against first version of Oracles virtual-box. IBM is probably the vendor with the most to loose by moving to the cloud. In the cloud everything needs to be commoditized and streamlined in order to save cost and manpower. IBM wants to deal with your large problems and make a premium on it.
This is because of the Tegra4, I bet lots of other tablet will arrive using that chipset also, then they all will have this resolution.
Just first iteration
The first generation of a new technology will always have shortcommings. If we see the same advances in head up googles than in mobile phone screens like in the last 10 years. I bet the future is looking so bright you have to wear shades. As long as the initial interest is above the investment threshold, there will be money for inventing the technology further. I bet both Apple and Samsung are putting lots of money into this and just talking the technology down until it matures into consumer quality and pricerange. then it will really take off.
sysadmin that monster
I'm unable to understand the size and complexity of those monsters, but I really like to know how they sysadmin those. How they provision and load balance applications and users. How long does it take from initial load until execution when you request 10000cores. What kind of checkpoint/restart software do they use.
I once wrote an MPI ping which I frequently ran on all large clusters and shmems I was able to get my hands on (I used to work with SGI HPC 10 years ago). And with the increase of cores and nodes the bandwidth and latency did suffer. On large systems it was very easy to just congest IO unless there were strict limitations on my user. Broadcast pings where out of the question, closely build up a 1to any core ping and build carefully selected latency and bandwith maps for each core to any other core in the system. And then try out 1to2, 1to3, 1to4 etc until peak bandwith was reached, then 2to2,2to3 etc and so on then at the end lookup the ones with the lowest overall latency and highest bandwidth combinations to find the system bandwidth.
AMD not to push Fusion Android tablets
I want an android tablet with a fusion gpu/cpu. Rumours say AMD is not interested in android and is all behind win8. IMHO a terrible mistake: win8 on netbook/tablet is sinking like titanic. AMD have sacked all their linux developers. And Why not a Fusion APU in some of the 150mill smartphones that ship with Android each quarter. So they are effectively abandoning the by far largest growing market where they may have a superior product. Something is fishy, either M$ has done some behind the scene investments into the empty koffers of AMD or its just incompetent management.
Re: How about a stock buyback??? Seems like smarter move...lots smarter than giving in to Loeb
You cant buy back stocks with money you do not have. A stock buyback is great if You have money in the bank with no idea how to spend (Apple, IBM, Intel etc). But Sony is deep in the red, so they have to wrestle out all the vaules they can find.
Re: Why so long?
After installing the code I see it waits 10 sec between each shoot so everything becomes static, that is why it takes so long 10 sec every move, would have been nice this was shortened down. but AI need to be smarter then to shorten, not much brute force then.
Re: Why so long?
Or is it trying the level multiple times to see what works and what doesn't? If it is doing this why does the article not mention it?
It tries shot after shot and sees how well it goes, sets angle and power and fires away.
This computation they have shortened down from 10sec to 1/10 because they have probably taken away the presentation and go directly onto the physics computation of the impact.
The nice thing is that they do not bend the rules just try and try, although it is not much AI in this because it is easy to compute the successrate for each shot. Try 10 shots then take the one that destroys most objects and go to next shot ets. it is static and not more than 5-6 birds. This is no chess solver like deep blue.
But it is cool and fun to watch.
Re: Linux as a desktop is a failure, its time to move on
The only program I've missed from windows was Visio. Now with libreoffice4 we now have a much better draw package. And with Steam now accelerating on linux. I would say the future has never looked brighter for the linux desktop.
Re: Is this some new Microshill tactic?
suse have suse studio, I use it to set up rpms for redhat because my big do it all rpm of our commercial app spec file just fails on RHEL6. After making the spec file through suse studio, it worked. So I develop all my company commercial code in open suse, then when it is finished I verify the code with suse studio and build for centos5/6. Very nice piece of software.
>But I'm fond of jfs as a file system, which for some reason Suse stopped supprting some time back.
JFS is in the 12.3 filesystem list, it is not the default though which is ext4, I myself always uses XFS.
I've had lots of cheap disks failing, but I've always managed to get xfs_repair to restore the disk into a readable condition. much faster than Spinrite.
Thank heaven for virtualization
I used to have something similar, but now I have lots of vmware images on one quad core 24GB workstation.
disk-share on host, and all kinds of linux (opensuse 11.0,11.4,12.1,12.2,12.3,centos5,6), winxp for all kinds of vpns for work and a win7 for gaming, different work images of our software so I can test at home. etc all in all I have 23 images on 2x2TB disks all running on vmware workstation v8.0.6. Fortunately I do not need to run more than max 2-3 vms at once.
I used to hate the frequent upgrades with OpenSuse, because I have a rather tricky wikimedia setup with some heavy configured plugins and getting this to work on a new system take a lot of time. Now I Just clone the image and start upgrading while the old one is running until it is ready. if it stalls I just start on a new clone.
Gaming in win7 vm on a linux host works fine. The most demaning game I've played have been Skyrim.
I played to level 67 and put 135 hours into it, so it was a fine experience.
But You need to have a nvidia card, I tried an AMD card and then it just froze, vmware complains saying there are issues with this card/driver on a linux host when you start the vm in accelerated mode.
I consider the $179 vmware license well spent money and well within a home budget.
I've used Xen and Virtual box also, but they are not in the same ballpark. especially considering performance and hw-accelerated gfx on guest vms.
HP get over it
Itanic is dead and has been for years. How long can you beat a dead horse?
The revenue stream from itanics dwindle day by day. There cant be much left.
if they jumped ship when this was announced they would have been in much better shape now.
There is a marked out there for linuxboxes with the same feature set as itanic superdomes,
Couldn't be that hard. SGI moved from itanium to Xeons in 2 years on their Altix line.
Nobody is missing the itanics. it was a bad design that lived way too long.
The slow single thread performance and poor intel compilers will not be missed.

KDE4.9 is fantastic. I've been using it ~8h/day since beginning of September and it has not crashed once.
Now you can move all icons around from anywhere to everywhere. The shortcuts are stable and always working, which was not the case earlier. Now I'm watining for KDE4.10
I rather use Samba
Why do you get only 35MByte/s write performance? Your network must be saturated.
I do not see the point in testing a NAS array when the network is the limitation.
If the Drobo is the limitation it is a bad selling point.
I tested my samba share from my fanless low end linux box exporting a cheap WD 2TB green disk and get 70MBytes/s write and 85MBytes/s read from a win7 client.
I only have a D-Link dir-825 wireless/gigabit router in between.
IMHO the samba swat web interface is just as easy as the Drobo.
