Since I could no longer comprehend the technical nature of the discovery, what is the consequence of this discovery? Will existing theories be changed (or validated)? Any complications to other theories?
I hope someone with more knowledge in the subject matter will be able to share.
I think the most important medicine is to surround yourself with people who care and are able to support. Me and my colleagues started a business. Things are going well now but I had those bout of depression before (including thoughts of suicide.) Before, I felt alone in an island. The image of me being perfect was so high that I didn't open up to other people.
Now, it is different, I've learned to share and ask for support from my family and close friends. I have learned that I am not superman and I do make mistakes. I have learned to take care of myself and love myself more.:) Life is so much better now.:)
P.S. May be one bonus for me is that I am generally a happy person living a simple life. Though one disadvantage is that if bad things happen, it does probably hit me harder than other people. I also didn't take any prescription medicine.
PCs have grown to be powerful and surprisingly durable enough that it will work well for five years. In our office, we do cascade our workstations where the powerful are for the graphics and video teams and go to cascade it slowly to the rest of the company. We have some computers running on Core 2 duo/quad that are still ok for use in administrative computers.
The only time we purchase computer is when the old system conks out and parts are no longer available (such as lga 775 motherboards) or we have a new employee to use it. But generally, the cpu, memory, monitor, keyboard, mouse are ok. So we do just replace parts (harddrive, power supply) instead of replacing the entire computer. One factor is to retire high wattage workstations in favor of the modern low power system that will hopefully reduce our energy consumption (we have one of the highest electricity rates in the world.)
I think this will happen to other computing devices such as mobile phones and tablets where Apple and Samsung recently reported a drop in income (started.) Afterwards, it will just reach some steady state replacement cycle much like what we have in PCs.
Moving forward, this 2014, we have a couple of high end workstations lined up and desktop PCs for purchase. This will hopefully slow down the demise of the PC industry that is seeing 82.6 MILLION of sales as of the recent quarter.
That's the problem. All people entering the USA have no protection as accorded to American citizens. You are treated as hostile unless proven otherwise. In the meantime, all rights are suspended with no expectation of being treated as a human being.
Being a foreigner, I have read numerous times of horror stories happening at the immigration. It's really discouraging to go to the USA even if you have all the best intentions to go there. Good thing I don't have any necessity to go there at this point in time.
At the end, I'm not sure it is helping thwart bad people from entering the USA.
I think this might help Microsoft too. If they can pull it off with a great user experience, people will be getting Windows to run both Windows software that they use (such as MS Office, and other corporate software) and run parallel Android apps for their personal stuff. This will be great in sandboxing the work and personal stuff in a computer. People will appreciative of the Windows environment because it can run whatever apps they like. It might also increase the adaptation of Windows (especially ver 8 and above.)
Recently, we built a Supermicro Workstation 7047GR-TRF configuration. I am revising the system configuration to update the parts to get a comparable overview: Supermicro Workstation 5037A-i - $580 Xeon E5-2643 v2 (fastest available) - $1552 Memory (4GB/ECC/DDR3-1866 x 4) - $240 Firepro W8000 (x2) - $2560 Intel SSD 910 400GB - $2000 Windows 8.1 Pro - $140 Others Accessories - $100 Total - $7,172 The base system will be pretty much high vs the $3,999 cost
In another comparison Supermicro Workstation 5037A-i - $580 Xeon E5-2697 v2 - $2750 Memory (16GB/ECC/DDR3-1866 x 4) - $840 Firepro W9000 (x2) - $6800 Intel SSD 910 800GB - $4000 Windows 8.1 Pro - $140 Others Accessories - $100 Total - $15210 The configured system is still pretty high compared to $9599 from Apple pricing
Although specifications cannot be matched one is to one, I believe that the Windows workstation can be reduced in pricing by changing the Intel PCIe SSD and GPU to avoid using the top of the line products.
For example, using the following Supermicro Workstation 5037A-i - $580 Xeon E5-2697 v2 - $2750 Memory (16GB/ECC/DDR3-1866 x 4) - $840 Quadro K5000 (x2) - $3200 Intel SSD DC S3700 200GB - $500 Windows 8.1 Pro - $140 Others Accessories - $100 Total - $8110 The configured Mac Pro is $8119 for the 256GB Storage and Dual D500.
So I guess the configuration will depend on the system.
For us though, we have found a more cost efficient alternative by buying a Supermicro 7047GR-TRF dual Intel Xeon socket and not using the top of the line for everything. But we are able to achieve 12 cores 2GHz, 64GB RAM, Nvidia K4000 for Display, Dual GTX680 GPU for compute, 8Gb FC Celerity HBA for around $5,000.00.
It will really depend on the applications to be used at the end. For us though, most of the applications are available in Windows and Linux configurations will limited Mac exclusivity so the PC solution is economical for us.
That's the problem we are experiencing at the office right now. We have been archiving to tape for quite sometime when we were starting with LTO3. Now we are at LTO5 (always one generation behind so the cost will be cheaper.)
The problem is backup speed. Our data are incompressible data (video, pictures) so we do not gain from the very high published backup rates. Our arrays are high speed hundreds of megabytes for streaming uncompressed video (even this is not compressible by the tape, which is very odd.) With terabytes of data generated, it is hard to keep up with backup. Our data is regularly restored because of access to archival storage. This creates data management challenges as well. Our main problem is the very long time to backup and restore TBs worth of data on a daily basis. Though it would be easier to scale by adding more tape libraries, but it is not cost effective to keep on adding (as well as adding more arrays to handle streaming read and write operations at the same time.) We are also using LTFS which automated backup software are not friendly too. Our requirement is different from the enterprise backup of multiplexing data from different servers at the same time to get speed. We backup projects one at a time on a tape (self contained.)
LTO6 does not go faster much from LTO5 speeds (160MB vs 120MB for uncompressed.) It is likely that the tape is reaching its limit (much like harddrive speeds have not grown with capacity increases over the years.) SSDs are faster but not effective in capacity wise though. So time to look for new technologies in storing and accessing data. In all, storage has not kept up with the performance improvements in CPU, memory, and other bandwidth links (Ethernet, fibre channel, etc.) We should be transferring at the 10GB/s range already at this time.
This is what happened with typhoon Yolanda/Haiyan. The local telcos were able to provide cellphone coverage through a mobile cell site. I'm sure all the electric poles are down and pretty much the last mile will be disconnected even though the exchange might still be working. Though electricity will be restored months from now, cellphone will be much convenient at the moment compared to restoring pots service which could take a very long time.
I guess pots will work when there are major blackouts and not in disasters where last mile will get cut.
People will still continue to search even though Google places banner ads all around. Look at Youtube, the ads placed there are a nuisance (for me) but it didn't stop people from watching videos. If you don't like it, suck it up. Since you'll still search from them anyway.
So pretty much unless another competitor challenges Google, they can pretty much do whatever the want.
What are you going to do with all that 1Gbps download speeds when your upload is capped to 512kbps?
We have been looking at a reliable provider for high upload speeds (uploading big content such as videos.) It seems LTE has got it right now (but signal reliability is not good especially when it rains.) Fiber is not yet available at our area (hopefully it does soon enough.)
I can remember back then when the campus network was put to a halt when a single laptop overloaded the poor Cisco router connected to the internet with too much requests. It took us quite some time to isolate the problem when we were using hubs and unmanaged switches. It was quite dramatic when I stormed the room in a middle of a presentation and pulled the UTP plug out of the computer!:)
I can also remember the Nimda worm back then when it infected a part of the network. Good thing we were using higher end switches and was able to isolate it pretty fast. We just got curious back then why all the network switch ports were blinking non-stop.
We have recently purchased around 300-400 drives of 500GB from Hitachi GST.
Our test method for checking the drives is filling up the drives with files (by replication) and do a hash check after (with comparison to the original source file.) Should the drive drop out (due to retry errors) it is RMAd. We do check for SMART after, as based on experience, it is fairly accurate on the sector reallocation count when the drive is in imminent failure. You also need to keep an eye on read statistics (we use iostat) to check if the performance is sub par. Normally, the drives will return to normal speeds after sector reallocation.
Based on our statistics, I would say that we do get around 1% defect rate for the drives (we have swapped out around 3 of them for 1 died and 2 having bad sectors.) After around a month, you get a further 1% or less (for typically having bad sectors further.) The same goes for after around 1 year.
In another interesting note, we purchased around 8 pcs of 2TB from Hitachi GST and probably from a batch problem, we had to replace around half of it due to bad sectors. We had a batch before of around 8 pcs of 2TB but everything were good.
As for performance, there are times when some of the drives deliver consistent performance (the hash checks don't all finish at the same time.) Though we don't classify the drives but my guesstimate is around 5%.
i thought that galaxy is defined as a group of starts, planets, etc. orbiting a central blackhole. but probably it's more of an observation than the definition though.
Android gets to have bugs here and there. One of the gripes that we have (me and my colleagues) is the calendar function. There is a problem with the synchronization of calendar between Android and Google Apps. The interpretation of Android for whole day entry and Google is different with the calendar entry going haywire to wrong date if you switch between a time entry and whole day. In addition, we get to have sync issues when changing times and dates of the calendar. It becomes "disconnected" where the Android calendar and Google calendar does not reflect the changes made to each other. However, when you delete the entry, it will be deleted on the other.
The solution is to use iPhone (one of my colleague has and does not experience any problems.) Google sucks with the own products rather third party integration. iOS It has better support with the synchronization and does not have any problems (indicating that it is an Android issue.) The synchronization is faster (instant update after saving the changes) instead of Android which requires some time to update (and not sure if it will really update.)
Given that Google has almost 20,000 employees as of end of 2009, what are all of them doing? Maybe their mantra of launching and keeping everything in beta actually materializes in the products that they deliver.
my question though from the image produced is that the metres/meters scale shows how "strong" or "weak" the gravity is from the normalized sphere? how is it in the unit of metres/meters? i would appreciate if someone could explain the map more detailed (i probably need another explanation from the article to understand it more.)
the goce satellite is cool. i mean i didn't realize that we have technology such as xenon ion thrusters. i thought they were limited to star trek. my ignorance.:((
why is there a need to compare this and that to ipod. reading initially the headline, i though it was an ipod with hiv detection capability. everybody seems to be comparing stuff to apple products. ipod this, ipad that, iphone there, etc.
but i will have to bow to the people at apple for their great marketing. they have successfully made their products the de facto standard for everyone to have.
it's amazing that intel has improved the speed of the their cores twice that of amd. amd now has to compete by putting two cores for intel's single core. now if intel would actually package 12 cores in a single cpu (much like the core2 quad days,) then that would kill amd. of course, intel wouldn't do this since they are doing well and enjoying very very big margins compared to amd.
this has been an exciting week, it's amd vs intel on the cpu side and now nvidia and amd on the graphics side with the release of fermi. this week has been a fast one! kudos to them and hope they continue to make better products so we can all benefit from it.:)
Look at the new Windows Phone 7. It looks like they are following the footsteps of Apple. I have the feeling they are going to release the phone in limited varieties. The new design is quite impressive for me, thinking of buying when its out. This is a far cry from existing Windows Mobile 6.5 and below where the phone OS is visible. The new one, I suspect will have limited tweaking and customization capabilities in the OS.
I guess what can happen is that if you want the status symbol, get Apple. If you want to want to be hip and new, get Microsoft. If you are the geeky kind, get Android. Business users will be Blackberry. The market is getting more polarized. I guess there won't be a one size fits all phone. I had to accept the fact that you can't get business features with all the hip stuff. I've been waiting for a good HTC WinMo prone with keyboard and it seems they have killed it. I will have to accept that keyboards will be a thing of the past. Oh well. Facebook, Twitter, and Youtube is the new internet.
