A fun day in the world of fibre connectivity

Two records were recently made with fibre optic connections, one for speed and one for length.  Researchers at Huawei and Proximus, who operate out of Belgium, recently transmitted data over a 1,040km fiber link at 1.4Tbps using Proximus' optical backbone.  Even more impressive for the network geeks out there was the spectral efficiency of the transmission, at 5.7 bits per second per Hertz, a new record for these researchers to be proud of.

Not to be out done, and putting Ryan's Ethernet run to shame, is a link that spanned 12,000 km (7,456 miles) without a repeater.  Certainly not at the speeds in the aforementioned link but a huge step in extending the reach of fibre based networks without the problems associated with simply increasing the strength of the signal.

"Proximus and Huawei have successfully trialled a super-channel optical signal, flinging out information at up to one terabit per second (Tbps)."

Introduction, Specifications, and Packaging

Lexar is Micron’s brand covering SD Cards, microSD Cards, USB flash drives, and card readers. Their card readers are known for being able to push high in the various speed grades, typically allowing transfers (for capable SD cards) much faster than what a typical built-in laptop or PC SD card reader is capable of. Today we will take a look at the Lexar ‘Professional Workflow’ line of flash memory connectivity options from Lexar.

150121-164114.jpg

This is essentially a four-bay hub device that can accept various card readers or other types of devices (a USB flash storage device as opposed to just a reader, for example). The available readers range from SD to CF to Professional Grade CFast cards capable of over 500 MB/sec.

We will be looking at the following items today:

  • Professional Workflow HR2
    • Four-bay Thunderbolt™ 2/USB 3.0 reader and storage drive hub
  • Professional Workflow UR1
    • Three-slot microSDHC™/microSDXC™ UHS-I USB 3.0 reader
  • Professional Workflow SR1
    • SDHC™/SDXC™ UHS-I USB 3.0 reader
  • Professional Workflow CFR1
    • CompactFlash® USB 3.0 reader
  • Professional Workflow DD256
    • 256GB USB 3.0 Storage Drive

Note that since we were sampled these items, Lexar has begun shipping a newer version of the SR1. The SR2 is a SDHC™/SDXC™ UHS-II USB 3.0 reader. Since we had no UHS-II SD cards available to test, this difference would not impact any of our testing speed results. There is also an HR1 model which has only USB 3.0 support and no Thunderbolt, coming in at a significantly lower cost when compared with the HR2 (more on that later).

Samsung Publishes Battery Enhancement Tech with Silicon

Tagged: Samsung, battery

When I was in my Physics program, there was a running joke that the word “Nano” should be a red flag when reading research papers. This one has graphene and nanoparticles, but it lacks quantum dots and it looks privately funded by a company, so we might be good. Kidding aside, while I have little experience with battery technology, they claim to have surrounded silicon anodes for lithium batteries with a layer of graphene.

This addition of graphene is said to counteract an issue where silicon expands as it is used and recharged. The paper, which again is the first source that I have seen discuss this issue, says that other attempts at using silicon adds vacant space around the anode for future growth. If you can keep the material at the same volume over its lifespan, you will be able to store more electricity in smaller devices. I wonder why Samsung would want something like that...

Windows Hololens is headed to space

Tagged: windows 10, microsoft, hololens

The new Windows Hololens will be headed to the ISS to let the NASA ground crew see through the eyes of astronauts onboard and even to annotate the view in real time.  Instead of using cameras and audio instructions, an astronaut could look at a peice of equipment and the engineer on the ground could overlay a visual of what repairs or changes would need to be completed, or text annotations giving details of the equipment.  One can only hope that the public might one day get a chance to see the ISS through the eyes of someone onboard.  The Inquirer also mentions several other projects the Hololens will be used in, from virtual tours of Mars to use in an underwater training facility to make the illusion of being in orbit even more convincing and valuable as training for future astronauts.  These devices will be wonderful for gaming but there are many other applications that they will be used for.

"Early demonstrations of Hololens included scenarios involving NASA researchers walking virtually on the surface of Mars through a sister project called OnSight, but now the idea has been extended to real-life interaction with ISS astronauts."

The rumours of ECS's withdrawl were greatly exaggerated

Subject: General Tech | June 25, 2015 - 01:20 PM |
Tagged: msi, rumour

In response to the news yesterday that ECS would be withdrawing from the DIY motherboard market, Sunny Yang, President of ECS released a statement denying any accuracy to that rumour.  He cites their participation in Computex where they showed off some of their new LEET gaming motherboard in addition to the LIVA mini-PC which received far more attention from the press.  They will still have a lot of struggling to do to take market from ASRock, Gigabyte and ASUS, not to mention MSI.  Here is to hoping their new products stand out and that their Dragon gaming Ethernet solution really does help with latency.

Warner Bros. Suspends Arkham Knight PC Sales

Tagged: batman, wb games, consolitis, gameworks, pc gaming, nvidia, amd

Over the last few days, the PC version of Batman: Arkham Knight has been receiving a lot of flak. Sites like PC Gamer were unable to review the game because they allege that Warner Brothers would not provide pre-release copies to journalists except for the PS4 version. This is often met with cynicism that can be akin to throwing darts in an unlit room with the assumption that a dartboard is in there somewhere. Other times, it is validated.

Whether or not the lack of PC review copies was related, the consensus is that Arkham Knight is a broken game. After posting a troubleshooting guide on the forums to help users choose the appropriate settings, WB Games has pulled the plug and suspended the game's sales on Steam until the issues are patched.

TotalBiscuit weighs in on the issues with his latest "Port Report".

No-one seems to be talking about what the issue is. Fortunately or unfortunately, I don't have the game myself so I cannot look and speculate based on debug information (which they probably disabled from the released game anyway). I could wildly speculate about DX11 limits from the number of elements on screen, but that is not based on any actual numbers. They could be really good at instancing and other tricks to keep the chunks of work being sent to the GPU as large as possible. I don't know. Whatever the issue is, it sounds pretty bad.

Samsung Laptops Disable Windows Update Automatically

A report from Paul Thurrott draws an uncomfortable comparison between the behavior of Samsung's notebook software and the recent Superfish controversy, and should be cause for concern for anyone using Samsung laptops with factory software.

The behavior is rather malware-like, as Thurrott point out: "In disabling Windows Update, the Samsung utility is behaving like malware—is, in fact, malware—which of course opens this event up to a comparison with Lenovo’s Superfish fiasco."

This behavior is apparently designed to prevent Microsoft drivers from installing over Samsung's proprietary versions, but this obviously has significant security implications. The fact that this happens automatically in the background is a signifant breach of trust for consumers. This discovery was initially made by a Microsoft MVP, Paul Barker, who posted this response from Samsung on his blog:

“When you enable Windows updates, it will install the Default Drivers for all the hardware no laptop which may or may not work,” he was told. “For example if there is USB 3.0 on laptop, the ports may not work with the installation of updates. So to prevent this, SW Update tool will prevent the Windows updates.”

There are instructions for disabling this software, but it might just be time for all of us to go to the trouble of creating our own official restore media and starting fresh with a clean install of Windows.

ECS getting out of the retail motherboard business?

Subject: General Tech | June 24, 2015 - 01:38 PM |
Tagged: ECS, motherboards, rumours

According to rumours DigiTimes has heard, ECS motherboards may no longer be sold by themselves and will only be found in OEM builds.  With the slowdown in the DIY PC market, arguably caused in part by a lack of reasons to completely upgrade gaming systems, ECS may be withdrawing from the market.  This bears to reason as their motherboard families have been much smaller than the competitions for a while now and you do not see much marketing for them on sites recently. It is always sad to see the marketplace shrink, hopefully this will give them the ability to focus more on their tablets and laptops and make those products more competitive; though that market is even tougher to succeed at than the motherboard business.

"Elitegroup Computer Systems (ECS) has announced that it will no longer actively market own-brand DIY motherboards but will undertake ODM/OEM production if clients have demand, and this is the equivalent of a gradual withdrawal from the global own-brand DIY motherboard market, according to Taiwan-based supply chain makers."

Razer Seiren Elite is a microphone of many talents

Subject: General Tech | June 23, 2015 - 06:04 PM |
Tagged: razer, Seiren Elite, microphone, audio

The Razer Seiren Elite is a microphone which can be used in almost any situation, for meetings it can be set to omnidirectional, for conversations it can be bidirectional, the stereo mode is good for aspiring musicians and the cardioid is great for solo podcasts.  All are accessible via a switch that sits on the same side as the gain adjustment and the zero delay headset connection is perfect for those recording as opposed to broadcasting live.  Thankfully the multiple modes do not mean that it can do many things poorly, the testing MadShrimps did showed it performed well in all four modes.  At $150 it is a very good value for those who need a microphone that can fulfill a variety of roles.

intro.jpg

"Thanks to the three 14mm condenser capsules, Seiren can function in four different modes: cardioid, stereo, omnidirectional or bidirectional, in order to accommodate different recording environments. Even if you do not use it in a professional environment, it should bring a lot of benefit to people which record streams daily/weekly thanks to the added clarity but also to the ones which talk a lot on Skype or any other audio/video conference programs."
