Comment It's simple... (Score 1) 83

They just need a 2-column setup.... current posts on one side, or one pane, and "important"/interesting posts in the other.

Plenty of space for it in the main twitter web page, mobile people may have to swipe left or right between screens... Tweetdeck could do it simply...

Comment Re:Before SSDs can replace HDs (Score 1) 272

Fusion-io did that 5 years ago with their pci-e flash cards. The drives were very vocal about any trauma they might have suffered and would drop into a reduced write mode if you didn't heed the warnings in order to get your attention... if you still ignored them, they would go read only and you'd be forced to copy your data off.

Comment SanDisk sells a 512TB 3U shelf... (Score 2) 219

SanDisk's Infiniflash is 512TB in a 3U chassis that is SAS-connected. You can front this with something like DataCore's SANsymphony to turn it into a NAS/SAN appliance.

The pricing looks to be around $1/GB, which is a ton cheaper than building a SAN of that capacity, plus it's much smaller in power/space/cooling.

Submission + - Facebook Finally Ends XMPP Support For 3rd Party Chat.

AcquaCow writes: Facebook has been pushing their Messenger app to all devices, requiring it for chatting with friends and family. It was announced last year that they would be ending their chat API and that the service would end on April 30, 2015. April passed, so did May, but the serviced remained functional. Finally, as of July 7th, 2015 it has not been possible to connect to chat.facebook.com. This doesn't seem to be an outage at this point...Looks like we have to wait for 3rd party messenger apps to adopt support for Facebook's Platform API v2 to allow new connectivity.

Comment Charge trap vs floating gate NAND... (Score 4, Interesting) 184

Newer 3D NAND is using a charge trap design which basically solves the electron leakage issue found with the older floating gate NAND...

Also, the move to the newer 3D NAND brings us back up to 40nm processes vs the 10nm gates we are currently working with, allowing for much better reliability.

You can't read game files faster because the process that reads the game file is single threaded vs multi-threaded... so it can only read as fast as a single thread can read.

A fully saturated CPU has enough lanes to do about 26-28GB/sec, but a single I/O thread might only be able to do 100-200MB/sec.

There was never any reason in the OS before today to make that any faster because the spinning disks that fed data to the CPUs couldn't do more than 100MB/sec.

Now that we have all this great flash, code needs to be re-written to be able to use other idle CPU time to spin up more threads and read the data faster.

It's worth remembering that 98k IOPS will be at a very small block size and will rapidly drop as you increase block size to 4K-1MB as the larger transfer size will directly equate to less I/O.

The real problem is that apps are not written for multi-threaded I/O which is what you really need in order to take advantage of the throughput provided by PCI-e flash.

Comment Re:It all depends on the workload... (Score 1) 162

Booting from RAID is more supported, and the support is baked into nearly every BIOS out there... booting PCI-e over NVMe or UEFI is brand new and very few things support it and all the code is new.

Booting through a raid card that has it's own BIOS is nothing like booting off of a native PCI-e device.

Comment Re:"old sata drives"? (Score 1) 162

The PCI-e native SSDs are indeed faster, the problem is, the code reading data off of them (your application/os) isn't written to take advantage of the increased speeds. Single threaded reads cap out at the read speed of a single thread, and that isn't that fast. This is especially true if they are 4K reads vs 1M reads, as you aren't going to saturate anything until you get up into larger read sizes.

To really take advantage of the bandwidth SSDs enable, you need to be running multiple parallel apps running multiple reads, or you need an app that can do multi-threaded reads.
