Friday to mark 14th annual SysAdmin Day

Here are a few tips for how to celebrate the occasion

Contests, cake and appropriately heartfelt thanks are central to the celebration of the 14th annual System Administrator Appreciation Day this Friday.

So exactly how are sysadmins and sysadmin admirers marking the occasion? What follows is a sampling of ways gleaned from Twitter and the hashtag #sysadminday:

First some of you (who don't read Network World) may need to learn the basics -- such as what a system administrator is -- as this amusing ambush video from Spiceworks demonstrates:

You also could show your appreciation by becoming a better user and/or sysadmin supervisor. Toward that end, ITWorld recently solicited input from actual system administrators for a story headlined, "9 reasons sys admins hate you."

Hate is almost certainly not in the vocabulary of your sysadmin, of course.

Contests are becoming a bigger part of SysAdmin Day every year as more vendors recognize the value of both system administrators and the publicity generated by giving away stuff. Among this year's contests:

Thwack's second annual SysAdmin Day meme contest;
Puppet Labs gif contest;
TrainSignal's call to complete this sentence: "All I want for Sysadmin Day is ___________________."
Dell KACE's IT desk photo contest (with an Alienware laptop up for grabs);
Cyber-Ark giving away a Kindle Fire to the sysadmin who best answers: "What skills and experience have you gained in the past year that will most help you in the coming one, and why?"

And here's a giveaway that doesn't even require a contest entry: In honor of SysAdmin Day, the League of Professional Systems Administrators is offering a $14 discount on its normal $50 membership fee.

(Geek-themed Meme of the Week Archive)

Nothing says appreciation quite like cash.

Unless you'd prefer to sing The System Administrator Song:

In any event, have a happy SysAdmin Day.

Microsoft denies giving government open access to customer data

If the government is cracking encrypted data Microsoft isn't providing the tools, company says

Even as it seeks more freedom to discuss how it turns over customer data to the government, Microsoft is revealing details that don’t violate laws meant to keep such transfers secret.

In a blog post yesterday, Microsoft General Counsel Brad Smith says:

= Microsoft does not provide direct access to Outlook.com emails or instant messages but does turn over content for specific accounts named in search warrants or court orders. “When we receive such a demand, we review it and, if obligated to we comply. We do not provide any government with the technical capability to access user content directly or by itself,” the post says.

BACKGROUND: Microsoft asks to disclose FISA requests to set the record straight

A LONGER VIEW: FISA court asks government to declassify secret order in Yahoo case

= Outlook.com uses HTTPS to encrypt Outlook.com instant messaging as it travels across the Internet and does not provide tools or encryption keys to help the government decrypt that traffic. “When we are legally obligated to comply with demands, we pull the specified content from our servers where it sits in an unencrypted state, and then we provide it to the government agency,” Smith writes.

= The government does not have direct access to customer information in Microsoft’s SkyDrive storage service. This year it has made changes to the procedures it uses to respond to requests for customer information to make it easier to handle an increasing volume.

“None of these changes provided any government with direct access to SkyDrive. Nor did any of them change the fact that we still require governments to follow legal processes when requesting customer data.”

= Microsoft moved its Skype peer-to-peer Internet-calling and instant messaging service infrastructure in-house to improve the technical back-end of the service. “These changes were not made to facilitate greater government access to audio, video, messaging or other customer data,” Smith says. “We will not provide governments with direct or unfettered access to customer data or encryption keys.”

= When the government wants emails and documents of Microsoft business customers that are stored in Microsoft clouds, the company recommends the government seek them from those customers directly. “We do not provide any government with the ability to break the encryption used between our business customers and their data in the cloud, nor do we provide the government with the encryption keys,” Smith writes.

In general, Microsoft doesn’t provide “direct and unfettered” access to customer data, he says, “Microsoft only pulls and then provides the specific data mandated by the relevant legal demand.”

That means it turns over data for accounts and identifiers specified by the legal requests, all of which Microsoft lawyers review to make sure they are valid, he says.

Windows 8.1 deep-dive review: Well, it's a start

Windows 8.1 deep-dive review: Well, it's a start
The preview of Windows 8.1 brings more cohesion, less frustration and a direct login to the desktop. But is it enough to save the OS?

With the just-released preview of Windows 8.1, Microsoft has gone a long way towards fixing many of the interface goofs and anomalies of Windows 8; it's also cleaned up the OS's rough edges and introduced some nice new features and apps.

Windows 8 remains a dual-interface operating system -- the touch-oriented "Modern" interface (previously called Metro) and the desktop -- but one that is less frustrating to use and a bit better integrated than previously. The changes don't solve all of Window 8's problems, but they make it more palatable to use.

The Start screen and the desktop have been at the core of most complaints about Windows 8. In Windows 8, you're forced to boot into the touch-oriented Start screen, and because it is primarily designed to launch Modern-style apps, many people would prefer to bypass it and head straight to the desktop when they log in. Microsoft made that impossible in Windows 8. Like many people, I was not pleased.

Finally, in Windows 8.1, you can bypass the Start screen and go to the desktop when you log in. Oddly enough, to do that, you don't change a setting on the Start screen. Instead, you have to do a bit of tweaking over at the desktop.

Go to the desktop, then right-click the taskbar. Select Properties and from the screen that appears, click or tap the Navigation tab -- a new tab added in Windows 8.1. Divided into two sections, Core navigation and Start screen, it lets you customize many of the frustrating things about the way the Start screen works.

Look for the setting "Go to the desktop instead of Start when I sign in" then check the box next to it. After that, each time you sign into Windows, you hop straight to the desktop. It's simple and straightforward, and desktop fans will be extremely pleased -- me among them.

There's more on that little tab that can go towards making the Start screen a more useful tool. If you have no need for the Start screen's tiled interface, and mainly use it as an app launcher, there are several settings that do that for you. Check the box next to "Show the Apps view automatically when I go to Start," and every time you head to the Start screen, you'll instead see the Apps view -- a listing of every Modern and desktop app on your system. Click an app to launch it. I find this far more useful than the Start screen's normal multi-sized tiles.

If you mainly use desktop apps rather than Modern ones, make sure to check the box next to "List desktop apps first in the Apps view when it's sorted by category." That way, your desktop apps show first on the screen, so it's easier to find them. I have found this small tweak quite helpful, because I frequently head here to launch Office. Now it appears high on the list.

Note that even if you leave the normal tiled Start screen intact and don't change the settings on the Navigation tab, there's now an easier way to get to the Apps view. On the Start screen down towards the bottom, there's a new arrow that was introduced in Windows 8.1. When you click it or tap it, you're sent to the Apps view.

Microsoft has also taken a very minor stab at trying to make the desktop and Start screen look as if they are a single, unified operating system, rather than two separate ones. A setting on the Navigation pane allows you to use the same wallpaper on the Start screen that you have on the desktop.

That's a nice piece of eye candy, but that's all it is. The two interfaces still look and work differently from one another. It's not quite like putting a lipstick on a pig; it's more like outfitting a pig and a giraffe in the same dress and hoping people will mistake them for twins.

The Core navigation section of the Navigation tab has a few settings that I find a bit less useful, but you might want to give them a try. You can turn off the Windows navigation feature that displays the Charms bar when you point your cursor at the upper-right corner of the screen. You can also turn off the navigation feature that switches between your recent apps when you click the upper-left corner.

There's one more setting there, and it slightly alters the Power User menu that pops up when you press the Windows key + X or right-click the lower-left corner of the screen. It replaces the Command prompt on the menu with the Windows Power Shell command-line automation tool. That setting is turned on by default in Windows 8.1.
The Start button and shutdown

The next big question you likely have about Windows 8.1 is whether there's a Start button. Well, there is and there isn't.

If you hover your mouse over the lower-left-hand portion of the Start screen or while you're in a Modern app, the button appears. It also appears on the desktop's taskbar (without your having to hover your mouse).

But calling it a Start button is a stretch, because that implies that it does what the Start button did in previous versions of Windows -- that is, launched a menu that lets you browse and launch your apps, search, find links to various Windows locations and services, and so on. Instead, it's just a task switcher that switches you between the Start screen and whatever else you were just doing. I rarely find myself clicking the Start button for the simple reason that it doesn't really start anything -- except my blood boiling about how useless it is.

However, Microsoft has taken one Start button feature from earlier Windows versions and made it more accessible in Windows 8.1: the ability to shut down, restart or put your device to sleep. Pull up the Power User menu and click Shut down to find those options.

In Windows 8.1, Microsoft has addressed a serious Windows 8 shortcoming: the close-to-useless Modern version of Internet Explorer 10. How seriously can you take a browser without the ability to create and use bookmarks, or that won't allow you to have more than 10 tabs open at a time?

Not very. And so I simply didn't use the Modern version of IE10.

In Windows 8.1, that's changed. Like every other browser out there, IE11 lets you have as many sites as you want open in separate tabs. And -- be still my beating heart! -- you can actually bookmark pages as Favorites. The bookmarking feature includes the ability to organize Favorites into folders.

However, the Favorites feature still isn't perfect. The Favorites in the Modern version of IE don't show up in the desktop version of IE, although the desktop IE Favorites do show up in the Modern version. That's something that should be fixed.

You can now also open tabs side by side, so that you can view more than one tab at a time, each in its own window onscreen. Normally you'll be only able to view two tabs this way, but on high-resolution displays, you can view up to four.

The new Internet Explorer also has improvements under the hood: notably, its addition of WebGL, a JavaScript API that renders interactive 3D graphics and 2D graphics. WebGL allows websites to essentially deliver the same interactive experiences as game and multimedia apps, but from inside a browser. Competing browsers such as Chrome already have this. In a world in which HTML5 and associated technologies will become standard, the lack of WebGL in Internet Explorer was a serious shortcoming. It's a shortcoming no longer.

Search has been considerably improved, which wasn't that difficult, given how poor Windows 8's original search feature was. Previously, when you did a search, you didn't see all the results on a single screen. Instead, you had to highlight the category you wanted to search through (such as Settings or Apps) and you'd see just those results.

In Windows 8.1, search has become more universal and far more powerful. You now get results from the Web (including graphics and videos) as well as local files, apps and settings, all presented in one interface.

If you like, you can filter to search only settings, only files, only Web images or only Web videos.

A great addition is the so-called Search Hero, which takes results from your device and the Web, and aggregates graphics, videos and information onto a simple-to-browse page. Here you can not only click to get more information, but if you search for a musician, you'll be able to play music right on the page, via a widget from the Xbox Music app. I find this feature especially useful, because it lets me search for and play music without having to launch the Xbox Music app.

How does Windows search do all this? The page you click to is essentially a Bing results page.

Keep in mind, though, that many searches you do won't display results this way, because many searches don't have a rich set of results including Wikipedia entries, photographs and videos.

This isn't to say that search is perfect. It still has its quirks. For example, if you're in the Windows Store, you can't simply start typing in a search term as you can on the Start screen. Instead, you need to display the Search charm, and then do a search.

Internet Explorer isn't the only Modern app that Microsoft has done work on. It's upgraded others, and included new ones as well. And in doing so, it's addressed a major Windows 8 shortcoming: the general awfulness of its Modern apps. Those apps have been extremely underpowered and feature-poor, anemic and touch-focused.

In Windows 8.1, that's changed. The Photos app, for example, now does more than just allow you to view photos, as it did in past versions. Now it includes some very good editing tools. Is it as powerful as Photoshop? Of course not. But it has plenty of features, including color editing, brightness and contrast changing, special effects, cropping, rotating, red-eye removal and more. I've used it several times for simple editing chores such as removing red eye and cropping, and found it simple and straightforward.

Microsoft has also introduced some very nifty new apps as well. The Food and Drink app is a particularly good one. When you find recipes, you'll be able to integrate them into a shopping list, meal planner or collections. It lets you plan out meals for the week. It's all very clear, clean and well done. And it also shows off a new trick Microsoft has taught Windows 8: hands-free mode. Rather than use the keyboard and mouse or touch, it lets you move from screen to screen by waving your hand (it uses your device's built-in camera).

Or at least, it's supposed to. I was never able to get hands-free mode to work, although at least one other reviewer has reported he got it working. Still, if it ever works properly in this app, it will be great for those times when you're in the kitchen, up to your elbows in flour and don't want to foul the screen.

There's also a semi-useful new Reading List app, which lets you clip content from the Web or other location, save it and then read it when you want.

To clip something, you open the Charms bar, select Share, choose Reading list and save the page. Later on, you can open the Reading List app to see everything you've saved. You can search through the list and delete from the list.

While it's nice to have this feature, the app pales compared to similar, more powerful apps already out there, such as Evernote. Reading List clips entire Web pages rather than highlighted content like Evernote does. And Reading List has one single list; it doesn't allow you to organize your data into folders or notebooks. I'm certainly not about to give up Evernote for it.

One of the frustrating things about the Modern interface has always been that you could change a few system settings via its Settings screen (accessible by going to the Charms bar and selecting Settings --> Change PC settings), but if you wanted to dig deep and change many of your settings, you had to head to the Control Panel on the desktop. That's still true to some extent in Windows 8.1, but more settings can now be changed from the Settings screen.

To make it easy to use those settings, the Settings screen has been redone. One of the most useful changes is that when you head there, you'll come to a Top settings screen, which makes it easy to change those settings you most frequently use. The screen alters according to which changes you make most often. So if you often change your Bing settings, they'll show up there.

If you're a dedicated tweaker like I am, you'll still need to head to the Control Panel to change things such as whether to show hidden files in File Explorer. But otherwise, you may be able to make most or all of your changes from the new Settings screen.

There have been plenty of other changes. SkyDrive, Microsoft's cloud storage service, is now more deeply ingrained into Windows. You can set it up so that by default all your files are saved to SkyDrive. You can also configure it to have all the photos you take with your mobile device automatically saved to SkyDrive.

The Windows Store has also been given a revamp, with a more pleasing graphical look and features that make it easier to browse and find apps. For example, when you've viewing an app and you scroll or swipe over to the right, you'll see a list of related apps, a feature that is old hat by now in other places, but is now finally making its way to the Windows Store.

Also, if you drag or swipe from the top of the screen you'll see a listing of all the categories in the store. Again, pretty much every other app store already has this, so the feature isn't new. More than anything, when it comes to the Windows Store, Microsoft is playing catch-up.

There is also more comprehensive support for portrait mode, such as in the News app. Unfortunately, not all apps are capable of portrait mode yet. Why should you care about this? Today, you likely don't. But a generation of Windows 8 and Windows RT mini tablets is on the way, and portrait mode is well suited for those devices.

File Explorer (called Windows Explorer in previous Windows versions) has been given some minor tweaks as well. The Computer view is now called This PC. And if you're looking for your file libraries, you won't find them. Instead, you'll see folders for Documents, Music, Pictures and so on, as well as a SkyDrive folder. This is just the latest iteration of Microsoft's long, winding, and confusing road of default organization for your files, which seems to change every several years.

Some reviewers tell you that this version of Windows 8 is the one that Microsoft should have shipped in the first place. They're only partially right.

It's true that the new features -- such as the ability to log in straight to the desktop and easier access to desktop apps -- should have been baked into Windows 8 right from the beginning. And overall, the new features have improved Windows 8.1 considerably, especially for die-hard desktop users and those who don't have touch screens.

But this still isn't the Windows 8 that should have been shipped. The ideal Windows 8 would have been a coherent operating system, with a single, unified interface and way of working, rather than a touch-oriented tablet operating system bolted uncomfortably onto a desktop operating system, and forced to do double-duty for two very different categories of hardware.

With Windows 8.1, you don't see the bolts quite so much. But they're still there, and so are two separate operating systems, coexisting a bit less uneasily than before. Still, this is a good enough upgrade that once it ships, all Windows 8 users should use it. They'll find that it makes Windows much better.

You can get the Windows 8.1 preview right now. But keep in mind that if you install it, you won't be able to upgrade directly to the final version of Windows 8.1 when it ships. Instead, you'll have to go through a reinstallation procedure, and when you do that, you'll have to reinstall all of your desktop apps.

Retracing Microsoft's missteps that sunk the Xbox One

The next-generation console wars are over and Microsoft has blown it. Even before PRISM blew up and people began to wonder about their electronics invading their privacy, the design of Xbox One is leaving such a bad taste in people's mouths that the PlayStation 4 has the lead before the two are even in the blocks.

Never mind that the PS4 will be $100 cheaper. That's the easy part. It doesn't take a lot of surfing to see that the incredible intrusiveness of the Xbox One will keep it out of a lot homes, including mine. And Sony is drawing thick lines of separation between itself and Microsoft, making as much noise about the subject as possible.

First off, you cannot play any games if your Xbox One does not connect to the Internet, at least once every 24 hours. Not even single player games. Until the Xbox One phones home, your game console is a DVD player. Sony has no such restriction.

If you disconnect the Kinect player, which is now mandatory and part of the Xbox One bundle, your games won't work. This caused all kinds of fears, with increasing irrationality and amusement, of what people feared it would do. They thought Kinect would record them walking around the house naked or engaging in various…acts.

Microsoft said no, "you are in control of when Kinect sensing is On, Off or Paused." When the system is off, the Kinect will only listen for a single phrase—"Xbox On"— before it comes on, and you will be able to disable that, too.

At first, people feared the Xbox One would not allow for playing used games. Microsoft punted on this one and said it will allow the sale of used games at "participating retailers," but only if the publisher allows it. Well, the publishers are the most vehement opponents of the used game business. Microsoft said it will not charge a fee for a hand-me-down disc, but the publishers certainly can.

The question then becomes which retailers will participate? We all know about Game Stop, but there are many independent shops that do this as well, mom-and-pop videogame and even record stores, the few that remain. Will Microsoft, EA, Activision, etc., want to go through the headache of certifying all these indie stories, or just go with a few big chains?

And if you want to loan a game to a friend? Get this: That person has to be on your Xbox Live friends list for at least 30 days and you can only lend them the game once. That pretty much kills not only lending to friends, but also rentals, like the few remaining video stores offer and mail order services like Game Fly.

The topper to all of this? Don Mattrick, president of the Interactive division at Microsoft, was asked about this issue. One example brought up was how popular the Xbox 360 was among soldiers stationed abroad in remote areas like Iraq and Afghanistan or on a submarine. His response? "We have a product for people who don't have some form of connectivity, it's called Xbox 360…if you have zero access to the Internet, it's an offline device."

See it for yourself:

Seriously, Microsoft, did you hire the old Divx development team from Circuit City?

Sony, of course, is making hay of this. They are loving it. Fans begged them not to engage in this kind of control prior to the release of the PS4, and they listened, for the most part.

Ars Technica reported that when Jack Tretton, president and CEO of Sony Computer Entertainment, slammed Microsoft at its E3 press conference with statements like "You can trade in the game, lend it to a friend, or keep it forever," the reaction was overwhelmingly positive.

It should come as no surprise that EA President Frank Gibeau told VentureBeat "Sony's having a great show." I didn't attend the show; to be honest, E3 is such an unpleasant experience I don't like to go and didn't ask for any assignments. But I can see the momentum shifting. There isn't a vendor-neutral site out there where the reader reaction is entirely behind Sony and entirely against Microsoft. Mattrick's 'let them eat cake' comment was the final straw.

The head of Australia's top civil liberties group, called Civil Liberties Australia, called Xbox One "the definition of a surveillance device under some Australian laws," and that Aussies "should vote with their wallets and skip the next Xbox" if Microsoft is not up front with its privacy rules. He's not alone. Germany's federal data protection commissioner, Peter Schaar, told Spiegel Online that Xbox One is nothing more than a monitoring device under the guise of a gaming console.

Rumors about the Xbox One license agreement and Kinect behavior had been floating around for a while, and just as Microsoft didn't listen to the bad reactions to Windows 8 during its beta cycle, it didn't listen to the massive opposition here, either. I guess they need to suffer another overwhelming consumer rejection again. And I suspect the only person who will lose his job will be Mattrick, because he told the truth.

Google's latest Penguin update lets you squeal on spammy websites -- as well as anyone else

Penguin 2.0 makes large-scale algorithm changes, affecting 2.3% of U.S.-English results

The latest version of Google's sophisticated anti-spam algorithm, dubbed Penguin 2.0, was announced yesterday in an official blog post from the company's well-known webspam czar, Mike Cutts.

The 2.0 label was applied, according to Cutts, because the update is a major one -- it includes changes to the underlying algorithms used to evaluate whether a website is spammy or not, not just the dataset Google uses. About 2.3% of queries in U.S. English will be visibly affected by the changes.

Cutts also posted a link to a webspam report page, where anyone can flag sites they consider spam for the attentions of Google's engineers. The form doesn't ask for any identification by the reporting party, requiring only a copy/pasted URL.

While this appears to present a golden opportunity for abuse -- as several Twitter responses to the announcement noted -- Cutts noted on Twitter that Google has always had an extensive array of options in place to report spammy sites, and that "we'll listen to feedback and look for ways to improve results."

Search Engine Land Editor Barry Schwartz wrote that this is actually the fourth major generation of Google's current anti-spam algorithm. However, its effects have been wider-ranging than all but the initial release of Penguin, which reached 3.1% of queries.

Cutts didn't discuss the algorithm changes in detail, so as not to provide too much information to black hat search engine optimization practitioners, but laid out some broad goals that Google is working toward in a video released earlier this month.

Ericsson makes bus windows part of a Wi-Fi network

Translucent layers of metal inside glass windows could block outside signals and reinforce those inside

Ericsson may have a contender for oddest networking product if it commercializes the wireless bus windows it demonstrated at this week's CTIA Wireless trade show.

The windows would have built-in, translucent antennas connected to an internal Wi-Fi system for passenger use while on the road. In the example Ericsson showed at CTIA, the dual-band Wi-Fi antenna was just a square of barely visible red metal embedded between layers of glass.

The mobile infrastructure giant demonstrated the concept on the upper level of its booth at CTIA, above a showcase of other technologies designed for so-called heterogeneous networks with both Wi-Fi and cellular radios. On Tuesday, the company announced enhancements to its network management software that will allow carriers to do a better job shifting subscribers between the two systems for the best possible coverage.

Ericsson's solution had its origin in a problem for wireless users on buses, cars and trains. For insulation and sun protection, some windows are now being built with thin, translucent layers of aluminum sandwiched between glass. Combined with the metal that covers the rest of a vehicle, those windows essentially create a so-called Faraday cage, a box that blocks all outside radio waves, said Bryan Coley, a marketing program manager at Ericsson.

Travelers in such a vehicle can't get online using the outdoor cell network, because it's signals are blocked. But Ericsson researchers decided to use the metal-in-glass principle to their advantage by building antennas into the windows along with the insulating metal. Though the window antennas are simple passive antennas, each one reinforces the internal network's signal.

The resulting network becomes like an in-flight Wi-Fi system on an airliner. Passengers log in to an internal Wi-Fi network that uses a longer range technology, such as LTE, to connect to the outside world.

At the same time, using signal-blocking windows and internal Wi-Fi prevents a situation that can strain outdoor cellular networks and is one of the problems with cellphone use on planes. If an airline passenger turns on a phone, it can cause cell towers on the ground to try to connect with it, diverting bandwidth that could be used by people on the ground. A train full of passengers unknowingly trying to get on cell towers as they speed past can make it hard for carriers to manage traffic. Plus, it can quickly draw down the battery life of the phones as they work hard to grab faint signals, Coley said.

The concept could also translate from buses and trains to glass-walled office buildings, he said. In addition to strengthening an interior Wi-Fi network, such antennas could improve coverage and capacity on indoor cellular systems while easing the demands on nearby cell towers that people indoors would otherwise be using.
