Bitcoin quietly goes legit

bitcoin-logo-3d-300x300The US Marshals Service doesn’t normally make economic policy but this week they apparently did so by auctioning 30,000 Bitcoins, a crypto currency I have written about before. This auction effectively legitimizes Bitcoins as part of the world economy. Am I the only one to notice this?


My first column on this subject was a cautionary tale pointing out the two great areas of vulnerability for Bitcoin: 1) the US Government might declare Bitcoins illegal, and; 2) someone might gain control of a majority of Bitcoins in which case their value could be manipulated. While number two is still theoretically possible it becomes less likely every day. And number one seems to have been put to rest by the U.S. Marshals.


The Marshals dispose of property confiscated by federal authorities, giving the proceeds to the Treasury Department and back to the Department of Justice. This auction -- worth about $11 million -- could not have happened without the permission of both agencies (Treasury and Justice). This is why I can claim that economic policy has been made, because it was authorized by the very agencies normally responsible for such policies.


When drug dealers lose their helicopters, Swiss watches, and Cigarette speed boats, the US Marshals sell them for money. However the Marshals don’t sell confiscated drugs because drugs are illegal and are destroyed. If Bitcoins were illegal they, too, would have been destroyed, not sold. Hence Bitcoins are not illegal.


And why should they be, really? Between derivative securities, futures and options there are already plenty of financial instruments that don’t look much like money to me but are treated as such.


Now, even though nobody has yet announced it, we can add Bitcoins to that list.


And who bought all those Bitcoins? Third generation VC Tim Draper, saying he’ll use the coins as a currency hedge.


In theory this threatens the US dollar‘s role as the reserve currency, but that theory is pretty weak with a finite number of Bitcoins even possible and most users still thinking of it as anonymous dollars.


It’s this anonymous nature of Bitcoins that has me puzzled. My guess is they aren’t anonymous at all and the NSA has thrown its elves into de-cyphering Bitcoin metadata. Otherwise this auction would never have happened.


Where is Edward Snowden when we need him?

Cloud sprawl: What is it, and how can you beat it?

moscow_cloud_1_fullwidth


Today's workplace plays host to employees using a variety of cloud services side-by-side with corporate-sanctioned IT. This often results in incongruent information sourcing and storage, typically known as cloud sprawl. Whilst software as a service (SaaS) can boost smarter working and innovation in businesses, information disparity issues need to be addressed to sustain efficient working environments.


As businesses adoption and management of cloud services matures, some are still suffering organizational inefficiencies due to cloud sprawl. At the moment, different software is being selected for different solutions by different departments or even individual members of staff; there is a knowledge gap where businesses aren't fully informed about how cloud technology can respond to business challenges in a different way to on-premise solutions, and so the potential for better information management is not being realized.


From the mid-market to larger enterprise, businesses need to enable company-wide education about the benefits of cloud.


To avoid cloud sprawl, there are a host of things that need to be considered; things that IT managers don't often think about when moving to cloud. People are still figuring out what cloud means to their business, and this often leads to information sprawl as new and different clouds are being deployed. Eventually cloud computing will mature and become standardized and interoperable, but until then there are certain sprawling issues to be addressed.


Cloud sprawl is also partly down to CIOs losing control of their IT strategies and procurement processes. Software as a Service has enabled more business departments (whether HR, marketing or finance) to make purchasing decisions oncloud solutions. For the CIO, this can lead to chaos as there are lots of different systems running in siloes. This can lead to challenges meeting overall goals, with CIOs effectively taking on a supply management role as they fight to manage disparate systems and ensure interoperability and business agility.


With 'Shadow IT' (systems businesses depend upon not deployed or managed by the IT team) becoming increasingly commonplace in the industry, teams are now making decisions without the CIO. As a result, we are seeing fragmentation of ultimate decision makers; not the desired effect of cloud computing.


There needs to be clear direction from the CIO to the business in terms of where it is necessary for information systems to share data; they must be clear on the need to interrelate information.


Individual departments may work perfectly well alone, but they still need the CIO to provide mechanisms to connect with each other and ensure compatibility. Many SaaS solutions have overlapping and duplicate functions, such as social or messaging plug-ins, which is another feature of cloud sprawl.


The key lesson to be learnt from the cloud sprawl issue is about the interconnection of business systems. This highlights particular problems for SaaS since linking systems together is critical to achieving maximum return. Organizations need to learn that systems might potentially overlap, and that solutions being too siloed or having too many overlaps may cause sprawl.

Microsoft brings better document collaboration to Office 365

06-Traditional-Edit-Reply-New-Edits-Reply-1024x514


With the introduction of Office 2013, Microsoft brought software as a service to the table -- something some analysts had long expected would happen. Under the moniker of Office 365, the company introduced a subscription model that allows for a monthly or annual fee and grants five licences to each person or family.


Today the software and services company rolls out an improvement to this offering, adding what it calls better document collaboration. The feature was actually announced earlier this year at the Exchange Developer Conference, but only now do we see the final product. Microsoft hopes this will eliminate the need to share documents via emails in an effort to work with other people on the files.


"Today, we’re thrilled to introduce the first of these enhancements which aims to improve the way people interact with files as attachments in their email. Now, you will be able to edit a document straight from Outlook Web App and attach this edited document to an email response in just a few clicks", the Office 365 team announces.


Added are side-by-side comparisons, which allow for viewing of the attachment and email next to one another, as opposed to flipping back and forth between the two. Users will also no longer need to download the attachment, as the document can be edited and returned right from this new view.


Finally, Microsoft promises a better user experience overall, with attached files being easier to see during the send process, and the ability to download multiple attachments in one single ZIP file.


"We are excited to deliver the first step in this enhanced document collaboration experience in Outlook Web App. We’ll have more enhancements to share later in the year. In the meantime, we look forward to your feedback on how we can continue to meet your needs", the team concludes. The company also promises more enhancements are on the way.






Almost 1 in 5 websites now blocked by censorship filters in the UK

censorship


Browse the web in the UK, and sooner or later there’s a good chance you’ll stumble across a website that’s been blocked. Sites like The Pirate Bay, Fenopy and H33t are no longer viewable due to court orders preventing access, and other sites -- many perfectly legitimate -- are being blocked by censorship filters.


It’s not quite as bad as living in China, but according to a new project by the Open Rights Group, ISPs are currently blocking 19 percent of tested websites.


The Blocked project is an online tool that lets you check whether a website is being censored by filters. So far it has checked over 105,000 websites, and disturbingly found over 20,000 which have been blocked by one or more ISPs.


The filters are designed to prevent children and young people from viewing content aimed at over 18s, including pornography and sites that talk about alcohol, smoking, anorexia and hate speech.


However, the Open Rights Group says the filters are routinely blocking sites which are not harmful to children -- sometimes seemingly by mistake, and at other times deliberately.


Executive Director of Open Rights Group, Jim Killock said: "Through, the Blocked project we wanted to find out about the impact of web filters. Already, our reports are showing that almost 1 in 5 websites tested are blocked, and that the problem of overblocking seems much bigger than we thought. Different ISPs are blocking different sites and the result is that many people, from businesses to bloggers, are being affected because people can’t access their websites".


One of the blocked sites is the political blog, Guido Fawkes whose Editor Paul Staines quipped: "We would really appreciate it if TalkTalk would remove us from their block list. The only people who block us are them and the Chinese government".


Other sites found to be blocked include a feminist rights blog and a Porsche dealership.


UK users can check to see if a website has been blocked by filters using the free checking tool at www.blocked.org.uk. It tests services from 3, Andrews & Arnold, BT, Everything Everywhere, O2, Plusnet, Sky Broadband, TalkTalk, Virgin Media and Vodafone.

Nokia Lumia 635 comes to T-Mobile

Nokia Lumia 635 T-Mobile


Now is a great time to be looking for a new Windows Phone 8.1 smartphone. The entry-level Nokia Lumia 630 is already available, while the Lumia 930 flagship will launch shortly, as will the more affordable Lumia 635. For those living in US, however, their options are far more limited.


The only Windows Phone 8.1 smartphone that is set to launch in US is Lumia 635. It will reach mobile operator T-Mobile, as well as its MetroPCS subsidiary, in just a couple of days. For Simple Choice customers, it goes for $7 per month for two years (the total cost is $168, when taking into account the $0 down payment).


It will be available first through Home Shopping Network, starting July 5, and through T-Mobile's online shop afterwards, starting July 9. MetroPCS customers will be able to buy Lumia 635 for less only days after, starting July 18, as it will be offered for $99 -- the "promotional price" is available both online and in "select" brick and mortar stores. So-called "participating" T-Mobile stores will also sell the MetroPCS version for $99, starting July 16.


Lumia 635 highlights include: 4.5-inch IPS display, glove-friendly, with a resolution of 480 by 854; 1.4 GHz dual-core Qualcomm Snapdragon 400 processor; 512 MB of RAM; 1,830 mAh battery; 8 GB of internal storage; microSD card slot (can house cards up to 128 GB in size); 5 MP back-facing camera with 720p video recording (there is no front-facing camera, however); Wi-Fi 802.11 b/g/n; GPS with Glonass; Bluetooth 4.0 and USB 2.0. The physical dimensions are 129.5 x 66.7 x 9.2 mm and weight is 134 grams.


T-Mobile also announces that both Lumia 521 and Lumia 925 will receive an over-the-air software upgrade to Windows Phone 8.1. There is a vague estimate for when this is expected to happen -- "later this year".






Stella makes it easy and fun to emulate classic Atari 2600 VCS games

Stella


When it comes to tapping into our fondness for old computing and gaming platforms, Stella has always been at the forefront. This cross-platform Atari 2600 VCS emulator first saw the public light of day back in 1996, and now -- 18 years later -- it may just have delivered it most significant update yet with the release of Stella 4.0.


Version 4, also available in 64-bit form, sees the emulator ported across to SDL2, which brings many new features and performance improvements.


Chief among these improvements is support for native hardware acceleration support on all three builds: Direct3D in Windows, and OpenGL on Mac and Linux. The transition to SDL2 also means it’s now possible to port Stella to iOS and Android platforms via OpenGLES.


Support for hardware acceleration is now mandatory, so users must ensure they’re using up-to-date drivers to support it; software rendering remains in place for now, but is no longer optimized and is no longer supported.


With hardware acceleration now a requirement, TIA TV effects have been extended to all video modes. Another notable improvement is that switching Stella to full-screen sees it use the current desktop resolution rather than resizing the desktop.


Users gain a more detailed view of a cartridge’s extended RAM via a new Debugger tab, while both AtariVox and SaveKey controllers gain the ability to complete erase the virtual EEPROM data in the debugger itself.


A new "savesnap" debugger prompt command has been added -- also accessible via the debugger’s TIA output area context menu. Selecting this saves the current TIA image as a PNG file.


A new "hidecursor" command line option has been implemented, allowing systems without a mouse to complete disable the cursor from view.


Version 4.0 is rounded off by updating the included PNG library to the latest stable version. Stella 4.0 (32-bit) and Stella 4.0 (64-bit) are both available now as a free, donationware downloads for Windows, Mac and Linux.






Sony Walkman turns 35 years old


Walkman


Sony launched the first Walkman in 1979, and this is this week the tech breakthrough is celebrating its 35th birthday.


Nowadays there are iPhones, devices that one can use as a phone, a computer and a music player. Before that, there were just iPods that enabled people to put their favorite music all onto one device and create playlists to fit their mood or preference. However, what many younger kids today won't know is that what started this whole process and changed the way we listened to music entirely was the introduction of the Walkman.


It was revolutionary. The idea that someone could listen to the music of their choice without disturbing anyone else really changed the impact music had on society, as it meant people could discover their own unique genre of music and just put on some headphones to listen to a whole tape of it really was something special.


Many features that the iPod now has originated from the Walkman like the small headphones that truly were different at the time but now are extremely popular with millions of people using them daily and thousands of different designs and types.


The Sony Walkman certainly did affect all areas, such as exercise due people were able to create their own music to exercise to which actually caused a boom in exercise. It also was used a lot during travel; in fact, the reason the Walkman made headphones was due the co-chairman of Sony wanting something that meant he could listen to his opera music while travelling on long journeys and that of course has led to the mass use of headphones and iPods being used today on a very regular basis.


So even though in this day and age we see the Walkman as a chunky, old fashioned MP3 player, it actually was the main and maybe only reason that iPods and other handheld MP3 were even thought of so for that reason and many others, it was and still is brilliant.
