• New Visual Studio 2012 Project Templates for DotNetNuke

  - by Chris Hammond

  Earlier this month Microsoft put the bits up for Visual Studio 2012 RTM out on MSDN Subscriber downloads, and during the first two weeks of September they will officially be releasing Visual Studio 2012. I started working with VS2012 late in the release candidate cycle, doing some DNN module development using my templates at http://christoctemplate.codeplex.com . These templates work fine in Visual Studio 2012 from my testing, but they still face the same problem that they had in Visual Studio 2008...(read more)

• HTG Explains: Why is Printer Ink So Expensive?

  - by Chris Hoffman

  Printer ink is expensive, more expensive per drop than fine champagne or even human blood. If you haven’t gone paperless, you’ll notice that you’re paying a lot for new ink cartridges — more than seems reasonable. Purchasing the cheapest inkjet printer and buying official ink cartridge replacements is the most expensive thing you can do. There are ways to save money on ink if you must continue to print documents. Cheap Printers, Expensive Ink Ink jet printers are often very cheap. That’s because they’re sold at cost, or even at a loss — the manufacturer either makes no profit from the printer itself or loses money. The manufacturer will make most of its money from the printer cartridges you buy later. Even if the company does make a bit of money from each printer sold, it makes a much larger profit margin on ink. Rather than selling you a printer that may be rather expensive, they want to sell you a cheap printer and make money on an ongoing basis by providing expensive printer ink. It’s been compared to the razor model — sell a razor cheaply and mark up the razor blades. Rather than making a one-time profit on the razor, you’ll make continuing profit as the customer keeps buying razor blade replacements — or ink, in this case. Many printer manufacturers go out of their way to make it difficult for you to use unofficial ink cartridges, building microchips into their official ink cartridges. If you use an unofficial cartridge or refill an official cartridge, the printer may refuse to use it. Lexmark once argued in court that unofficial microchips that enable third-party ink cartridges would violate their copyright and Lexmark has argued that creating an unofficial microchip to bypass this restriction on third-party ink would violate Lexmark’s copyright and be illegal under the US DMCA. Luckily, they lost this argument. What Printer Companies Say Printer companies have put forth their own arguments in the past, attempting to justify the high cost of official ink cartridges and microchips that block any competition. In a Computer World story from 2010, HP argued that they spend a billion dollars each year on “ink research and development.” They point out that printer ink “must be formulated to withstand heating to 300 degrees, vaporization, and being squirted at 30 miles per hour, at a rate of 36,000 drops per second, through a nozzle one third the size of a human hair. After all that it must dry almost instantly on the paper.” They also argue that printers have become more efficient and use less ink to print, while third-party cartridges are less reliable. Companies that use microchips in their ink cartridges argue that only the microchip has the ability to enforce an expiration date, preventing consumers from using old ink cartridges. There’s something to all these arguments, sure — but they don’t seem to justify the sky-high cost of printer ink or the restriction on using third-party or refilled cartridges. Saving Money on Printing Ultimately, the price of something is what people are willing to pay and printer companies have found that most consumers are willing to pay this much for ink cartridge replacements. Try not to fall for it: Don’t buy the cheapest inkjet printer. Consider your needs when buying a printer and do some research. You’ll save more money in the long run. Consider these basic tips to save money on printing: Buy Refilled Cartridges: Refilled cartridges from third parties are generally much cheaper. Printer companies warn us away from these, but they often work very well. Refill Your Own Cartridges: You can get do-it-yourself kits for refilling your own printer ink cartridges, but this can be messy. Your printer may refuse to accept a refilled cartridge if the cartridge contains a microchip. Switch to a Laser Printer: Laser printers use toner, not ink cartridges. If you print a lot of black and white documents, a laser printer can be cheaper. Buy XL Cartridges: If you are buying official printer ink cartridges, spend more money each time. The cheapest ink cartridges won’t contain much ink at all, while larger “XL” ink cartridges will contain much more ink for only a bit more money. It’s often cheaper to buy in bulk. Avoid Printers With Tri-Color Ink Cartridges: If you’re printing color documents, you’ll want to get a printer that uses separate ink cartridges for all its colors. For example, let’s say your printer has a “Color” cartridge that contains blue, green, and red ink. If you print a lot of blue documents and use up all your blue ink, the Color cartridge will refuse to function — now all you can do is throw away your cartridge and buy a new one, even if the green and red ink chambers are full. If you had a printer with separate color cartridges, you’d just have to replace the blue cartridge. If you’ll be buying official ink cartridges, be sure to compare the cost of cartridges when buying a printer. The cheapest printer may be more expensive in the long run. Of course, you’ll save the most money if you stop printing entirely and go paperless, keeping digital copies of your documents instead of paper ones. Image Credit: Cliva Darra on Flickr

• 'Photo editor' and 'RAW editor' in Shotwell

  - by Chris Wilson

  The preference menu in Shotwell allows the user to specify both an 'External photo editor' and an 'External RAW editor', but I'm confused as to why two external editors would be required. I'm not a photographer, so this confusion may simply be a result of my ignorance, but I thought RAW images were unprocessed photographs, in which case two editors would be kinda redundant. Am I simply missing one of the finer details of photograph processing?

• Missing features from WebGL and OpenGL ES

  - by Chris Smith

  I've started using WebGL and am pleased with how easy it is to leverage my OpenGL (and by extension OpenGL ES) experience. However, my understanding is as follows: OpenGL ES is a subset of OpenGL WebGL is a subset of OpenGL ES Is this correct for both cases? If so, are there resources for detailing which features are missing? For example, one notable missing feature is glPushMatrix and glPopMatrix. I don't see those in WebGL, but in my searches I cannot find them referenced in OpenGL ES material either.

• Exploring the Excel Services REST API

  - by jamiet

  Over the last few years Analysis Services guru Chris Webb and I have been on something of a crusade to enable better access to data that is locked up in countless Excel workbooks that litter the hard drives of enterprise PCs. The most prominent manifestation of that crusade up to now has been a forum thread that Chris began on Microsoft Answers entitled Excel Web App API? Chris began that thread with: I was wondering whether there was an API for the Excel Web App? Specifically, I was wondering if it was possible (or if it will be possible in the future) to expose data in a spreadsheet in the Excel Web App as an OData feed, in the way that it is possible with Excel Services? Up to recently the last 10 words of that paragraph "in the way that it is possible with Excel Services" had completely washed over me however a comment on my recent blog post Thoughts on ExcelMashup.com (and a rant) by Josh Booker in which Josh said: Excel Services is a service application built for sharepoint 2010 which exposes a REST API for excel documents. We're looking forward to pros like you giving it a try now that Office365 makes sharepoint more easily accessible.  Can't wait for your future blog about using REST API to load data from Excel on Offce 365 in SSIS. made me think that perhaps the Excel Services REST API is something I should be looking into and indeed that is what I have been doing over the past few days. And you know what? I'm rather impressed with some of what Excel Services' REST API has to offer. Unfortunately Excel Services' REST API also has one debilitating aspect that renders this blog post much less useful than it otherwise would be; namely that it is not publicly available from the Excel Web App on SkyDrive. Therefore all I can do in this blog post is show you screenshots of what the REST API provides in Sharepoint rather than linking you directly to those REST resources; that's a great shame because one of the benefits of a REST API is that it is easily and ubiquitously demonstrable from a web browser. Instead I am hosting a workbook on Sharepoint in Office 365 because that does include Excel Services' REST API but, again, all I can do is show you screenshots. N.B. If anyone out there knows how to make Office-365-hosted spreadsheets publicly-accessible (i.e. without requiring a username/password) please do let me know (because knowing which forum on which to ask the question is an exercise in futility). In order to demonstrate Excel Services' REST API I needed some decent data and for that I used the World Tourism Organization Statistics Database and Yearbook - United Nations World Tourism Organization dataset hosted on Azure Datamarket (its free, by the way); this dataset "provides comprehensive information on international tourism worldwide and offers a selection of the latest available statistics on international tourist arrivals, tourism receipts and expenditure" and you can explore the data for yourself here. If you want to play along at home by viewing the data as it exists in Excel then it can be viewed here. Let's dive in.   The root of Excel Services' REST API is the model resource which resides at: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model Note that this is true for every workbook hosted in a Sharepoint document library - each Excel workbook is a RESTful resource. (Update: Mark Stacey on Twitter tells me that "It's turned off by default in onpremise Sharepoint (1 tickbox to turn on though)". Thanks Mark!) The data is provided as an ATOM feed but I have Firefox's feed reading ability turned on so you don't see the underlying XML goo. As you can see there are four top level resources, Ranges, Charts, Tables and PivotTables; exploring one of those resources is where things get interesting. Let's take a look at the Tables Resource: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model/Tables Our workbook contains only one table, called ‘Table1’ (to reiterate, you can explore this table yourself here). Viewing that table via the REST API is pretty easy, we simply append the name of the table onto our previous URI: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model/Tables('Table1') As you can see, that quite simply gives us a representation of the data in that table. What you cannot see from this screenshot is that this is pure HTML that is being served up; that is all well and good but actually we can do more interesting things. If we specify that the data should be returned not as HTML but as: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model/Tables('Table1')?$format=image then that data comes back as a pure image and can be used in any web page where you would ordinarily use images. This is the thing that I really like about Excel Services’ REST API – we can embed an image in any web page but instead of being a copy of the data, that image is actually live – if the underlying data in the workbook were to change then hitting refresh will show a new image. Pretty cool, no? The same is true of any Charts or Pivot Tables in your workbook - those can be embedded as images too and if the underlying data changes, boom, the image in your web page changes too. There is a lot of data in the workbook so the image returned by that previous URI is too large to show here so instead let’s take a look at a different resource, this time a range: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model/Ranges('Data!A1|C15') That URI returns cells A1 to C15 from a worksheet called “Data”: And if we ask for that as an image again: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model/Ranges('Data!A1|C15')?$format=image Were this image resource not behind a username/password then this would be a live image of the data in the workbook as opposed to one that I had to copy and upload elsewhere. Nonetheless I hope this little wrinkle doesn't detract from the inate value of what I am trying to articulate here; that an existing image in a web page can be changed on-the-fly simply by inserting some data into an Excel workbook. I for one think that that is very cool indeed! I think that's enough in the way of demo for now as this shows what is possible using Excel Services' REST API. Of course, not all features work quite how I would like and here is a bulleted list of some of my more negative feedback: The URIs are pig-ugly. Are "_vti_bin" & "ExcelRest.aspx" really necessary as part of the URI? Would this not be better: http://server/Documents/TourismExpenditureInMillionsOfUSD.xlsx/Model/Tables(‘Table1’) That URI provides the necessary addressability and is a lot easier to remember. Discoverability of these resources is not easy, we essentially have to handcrank a URI ourselves. Take the example of embedding a chart into a blog post - would it not be better if I could browse first through the document library to an Excel workbook and THEN through the workbook to the chart/range/table that I am interested in? Call it a wizard if you like. That would be really cool and would, I am sure, promote this feature and cut down on the copy-and-paste disease that the REST API is meant to alleviate. The resources that I demonstrated can be returned as feeds as well as images or HTML simply by changing the format parameter to ?$format=atom however for some inexplicable reason they don't return OData and no-one on the Excel Services team can tell me why (believe me, I have asked). $format is an OData parameter however other useful parameters such as $top and $filter are not supported. It would be nice if they were. Although I haven't demonstrated it here Excel Services' REST API does provide a makeshift way of altering the data by changing the value of specific cells however what it does not allow you to do is add new data into the workbook. Google Docs allows this and was one of the motivating factors for Chris Webb's forum post that I linked to above. None of this works for Excel workbooks hosted on SkyDrive This blog post is as long as it needs to be for a short introduction so I'll stop now. If you want to know more than I recommend checking out a few links: Excel Services REST API documentation on MSDNSo what does REST on Excel Services look like??? by Shahar PrishExcel Services in SharePoint 2010 REST API Syntax by Christian Stich.

• How to Connect Your Android to Your PC’s Internet Connection Over USB

  - by Chris Hoffman

  People often “tether” their computers to their smartphones, sending their computer’s network traffic over the device’s cellular data connection. “Reverse tethering” is the opposite – tethering your Android smartphone or tablet to your PC to use your PC’s Internet connection. This method requires a rooted Android and a Windows PC, but it’s very easy to use. If your computer has Wi-Fi, it may be easier to create a Wi-Fi hotspot using a utility like Connectify instead.

• HTG Explains: Are You Using IPv6 Yet? Should You Even Care?

  - by Chris Hoffman

  IPv6 is extremely important for the long-term health of the Internet. But is your Internet service provider providing IPv6 connectivity yet? Does your home network support it? Should you even care if you’re using IPv6 yet? Switching from IPv4 to IPv6 will give the Internet a much larger pool of IP addresses. It should also allow every device to have its own public IP address, rather than be hidden behind a NAT router. IPv6 is Important Long-Term IPv6 is very important for the long-term health of the Internet. There are only about 3.7 billion public IPv4 addresses. This may sound like a lot, but it isn’t even one IP address for each person on the planet. Considering people have more and more Internet-connected devices — everything from light bulbs to thermostats are starting to become network-connected — the lack of IP addresses is already proving to be a serious problem. This may not affect those of us in well-off developed countries just yet, but developing countries are already running out of IPv4 addresses. So, if you work at an Internet service provider, manage Internet-connected servers, or develop software or hardware — yes, you should care about IPv6! You should be deploying it and ensuring your software and hardware works properly with it. It’s important to prepare for the future before the current IPv4 situation becomes completely unworkable. But, if you’re just typical user or even a typical geek with a home Internet connection and a home network, should you really care about your home network just yet? Probably not. What You Need to Use IPv6 To use IPv6, you’ll need three things: An IPv6-Compatible Operating System: Your operating system’s software must be capable of using IPv6. All modern desktop operating systems should be compatible — Windows Vista and newer versions of Windows, as well as modern versions of Mac OS X and Linux. Windows XP doesn’t have IPv6 support installed by default, but you shouldn’t be using Windows XP anymore, anyway. A Router With IPv6 Support: Many — maybe even most — consumer routers in the wild don’t support IPv6. Check your router’s specifications details to see if it supports IPv6 if you’re curious. If you’re going to buy a new router, you’ll probably want to get one with IPv6 support to future-proof yourself. If you don’t have an IPv6-enabled router yet, you don’t need to buy a new one just to get it. An ISP With IPv6 Enabled:  Your Internet service provider must also have IPv6 set up on their end. Even if you have modern software and hardware on your end, your ISP has to provide an IPv6 connection for you to use it. IPv6 is rolling out steadily, but slowly — there’s a good chance your ISP hasn’t enabled it for you yet. How to Tell If You’re Using IPv6 The easiest way to tell if you have IPv6 connectivity is to visit a website like testmyipv6.com. This website allows you to connect to it in different ways — click the links near the top to see if you can connect to the website via different types of connections. If you can’t connect via IPv6, it’s either because your operating system is too old (unlikely), your router doesn’t support IPv6 (very possible), or because your ISP hasn’t enabled it for you yet (very likely). Now What? If you can connect to the test website above via IPv6, congratulations! Everything is working as it should. Your ISP is doing a good job of rolling out IPv6 rather than dragging its feet. There’s a good chance you won’t have IPv6 working properly, however. So what should you do about this — should you head to Amazon and buy a new IPv6-enabled router or switch to an ISP that offers IPv6? Should you use a “tunnel broker,” as the test site recommends, to tunnel into IPv6 via your IPv4 connection? Well, probably not. Typical users shouldn’t have to worry about this yet. Connecting to the Internet via IPv6 shouldn’t be perceptibly faster, for example. It’s important for operating system vendors, hardware companies, and Internet service providers to prepare for the future and get IPv6 working, but you don’t need to worry about this on your home network. IPv6 is all about future-proofing. You shouldn’t be racing to implement this at home yet or worrying about it too much — but, when you need to buy a new router, try to buy one that supports IPv6.

• Best SEO practices for mobile URLs: 301, rel=canonical, or something else?

  - by Chris

  I am developing a site with a mobile version and am trying to figure the appropriate way to manage the URLs for search engines. So far I've considered: Having a mobile site with rel="canonical" links to the regular site. Putting both the mobile site and full site on one URL, and doing user agent sniffing. Another opinion: Spencer: "If you have a mobile site at a separate location or URL, you should 301 redirect each and every mobile page to its corresponding page on your main website. Employ user agent detection so that the mobile optimized version is served up if someone's coming in from a hand-held. - http://developer.practicalecommerce.com/articles/1722-Mobile-site-Development-Best-Practices-for-SEO-Usability Both 2 and 3 make it hard for a user who wants to switch to the full site or mobile site manually, but I'm not sure 1 is the best alternative.

• How to Find Your Computer’s Private & Public IP Addresses

  - by Chris Hoffman

  An IP address (or Internet Protocol address) identifies each networked computer and device on a network. When computers communicate with each other on the Internet or a local network, they send information to each other’s IP addresses. Your computer likely has public and private IP addresses. You’ll need the IP address if you’re hosting server software – the client computers will need your computer’s IP address to connect to it.

• Windows 8.1 Will Start Encrypting Hard Drives By Default: Everything You Need to Know

  - by Chris Hoffman

  Windows 8.1 will automatically encrypt the storage on modern Windows PCs. This will help protect your files in case someone steals your laptop and tries to get at them, but it has important ramifications for data recovery. Previously, “BitLocker” was available on Professional and Enterprise editions of Windows, while “Device Encryption” was available on Windows RT and Windows Phone. Device encryption is included with all editions of Windows 8.1 — and it’s on by default. When Your Hard Drive Will Be Encrypted Windows 8.1 includes “Pervasive Device Encryption.” This works a bit differently from the standard BitLocker feature that has been included in Professional, Enterprise, and Ultimate editions of Windows for the past few versions. Before Windows 8.1 automatically enables Device Encryption, the following must be true: The Windows device “must support connected standby and meet the Windows Hardware Certification Kit (HCK) requirements for TPM and SecureBoot on ConnectedStandby systems.”  (Source) Older Windows PCs won’t support this feature, while new Windows 8.1 devices you pick up will have this feature enabled by default. When Windows 8.1 installs cleanly and the computer is prepared, device encryption is “initialized” on the system drive and other internal drives. Windows uses a clear key at this point, which is removed later when the recovery key is successfully backed up. The PC’s user must log in with a Microsoft account with administrator privileges or join the PC to a domain. If a Microsoft account is used, a recovery key will be backed up to Microsoft’s servers and encryption will be enabled. If a domain account is used, a recovery key will be backed up to Active Directory Domain Services and encryption will be enabled. If you have an older Windows computer that you’ve upgraded to Windows 8.1, it may not support Device Encryption. If you log in with a local user account, Device Encryption won’t be enabled. If you upgrade your Windows 8 device to Windows 8.1, you’ll need to enable device encryption, as it’s off by default when upgrading. Recovering An Encrypted Hard Drive Device encryption means that a thief can’t just pick up your laptop, insert a Linux live CD or Windows installer disc, and boot the alternate operating system to view your files without knowing your Windows password. It means that no one can just pull the hard drive from your device, connect the hard drive to another computer, and view the files. We’ve previously explained that your Windows password doesn’t actually secure your files. With Windows 8.1, average Windows users will finally be protected with encryption by default. However, there’s a problem — if you forget your password and are unable to log in, you’d also be unable to recover your files. This is likely why encryption is only enabled when a user logs in with a Microsoft account (or connects to a domain). Microsoft holds a recovery key, so you can gain access to your files by going through a recovery process. As long as you’re able to authenticate using your Microsoft account credentials — for example, by receiving an SMS message on the cell phone number connected to your Microsoft account — you’ll be able to recover your encrypted data. With Windows 8.1, it’s more important than ever to configure your Microsoft account’s security settings and recovery methods so you’ll be able to recover your files if you ever get locked out of your Microsoft account. Microsoft does hold the recovery key and would be capable of providing it to law enforcement if it was requested, which is certainly a legitimate concern in the age of PRISM. However, this encryption still provides protection from thieves picking up your hard drive and digging through your personal or business files. If you’re worried about a government or a determined thief who’s capable of gaining access to your Microsoft account, you’ll want to encrypt your hard drive with software that doesn’t upload a copy of your recovery key to the Internet, such as TrueCrypt. How to Disable Device Encryption There should be no real reason to disable device encryption. If nothing else, it’s a useful feature that will hopefully protect sensitive data in the real world where people — and even businesses — don’t enable encryption on their own. As encryption is only enabled on devices with the appropriate hardware and will be enabled by default, Microsoft has hopefully ensured that users won’t see noticeable slow-downs in performance. Encryption adds some overhead, but the overhead can hopefully be handled by dedicated hardware. If you’d like to enable a different encryption solution or just disable encryption entirely, you can control this yourself. To do so, open the PC settings app — swipe in from the right edge of the screen or press Windows Key + C, click the Settings icon, and select Change PC settings. Navigate to PC and devices -> PC info. At the bottom of the PC info pane, you’ll see a Device Encryption section. Select Turn Off if you want to disable device encryption, or select Turn On if you want to enable it — users upgrading from Windows 8 will have to enable it manually in this way. Note that Device Encryption can’t be disabled on Windows RT devices, such as Microsoft’s Surface RT and Surface 2. If you don’t see the Device Encryption section in this window, you’re likely using an older device that doesn’t meet the requirements and thus doesn’t support Device Encryption. For example, our Windows 8.1 virtual machine doesn’t offer Device Encryption configuration options. This is the new normal for Windows PCs, tablets, and devices in general. Where files on typical PCs were once ripe for easy access by thieves, Windows PCs are now encrypted by default and recovery keys are sent to Microsoft’s servers for safe keeping. This last part may be a bit creepy, but it’s easy to imagine average users forgetting their passwords — they’d be very upset if they lost all their files because they had to reset their passwords. It’s also an improvement over Windows PCs being completely unprotected by default.

• Couldn't find package - But package is listed in the Packages file

  - by Chris

  (Quoted items are redacted elements) I am using a private repository and an currently trying to repackage some packages 3rd-party packages. I extract the package, make a few modifications (just the control files to fit with company policy - though sometimes file install locations though not in this case) and repackage (and usually rename). Normally I copy the files into a new blank debhelper project and reconstruct the package, however, with a recent one I attempting to convert and some libraries and stuff aren't linking properly (I did copy the postinst, postrm, and preinst files along with all DEDIAN files exactly), the original package worked, but my repackage doesn't, despite providing the same files in the same locations and the same postinst and preinst. So I was attempting to just modify the current packages control files (as the original package is not very good and will not list in our repository and getting a better one from the 3rd party is not an option). I also renamed the package. I did the following: dpkg-deb -R "directory" Modify DEBIAN/control dpkg-deb -b "directory" "package name I want" I did this and put it in our repository. The package shows up in the "Packages" file on the repository and running apt-get update on the client side shows the package in: /var/lib/apt/lists/"server"_"location"_Packages However when I do an apt-get install on the package name (as listed in the Packages file - I did a copy paste) it says it can't find the package. Same with an apt-cache search The Packages listings is as follow (name redacted): Package: "package name" Priority: extra Section: unknown Maintainer: "maintainer" Architecture: any Version: 1.0-lucid5 Depends: libc Filename: "directory"/"package_filename" Size: 2206292 MD5sum: "md5sum" SHA1: "sha key" SHA256: "sha256 key" Description: "description" I am running as sudo (and tried as root as well). I don't understand why apt-get won't see the package. Can you point out any flaws in what I have done, or perhaps some help on getting apt-get to properly see the package. Or perhaps an alternative. I am not even sure if this is a valid way to repackage something. Thanks.

• 3D Ray Casting / Picking

  - by Chris

  Hi, I am not sure if I should post this link, but I feel this falls into game development just as much as it does math. I have a ray cast's far and near values and I am trying to calculate the end point of the ray so that I can either draw a line to show the ray, or render an object at the end of 3d mouse position. Here is my post on the stack overflow math site, if there is a problem with me doing this just close the thread. Thank you. http://math.stackexchange.com/questions/15918/help-with-matrix-mathematica

• Macbook Pro wifi won't work

  I opened xdiganose and it told me to go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware in order to download and install the wireless driver. I followed the instructions for Ubuntu and it aborted the installation saying something about an unsupported device (I should've saved the output, I'm using a late 2011 13" Macbook Pro.) Now when I trysudo apt-get install firmware-b43-installer I get this: Reading package lists... Done Building dependency tree Reading state information... Done firmware-b43-installer is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 338 not upgraded. What do I do?

• HTG Explains: How Private Browsing Works and Why It Doesn’t Offer Complete Privacy

  - by Chris Hoffman

  Private Browsing, InPrivate Browsing, Incognito Mode – it has a lot of names, but it’s the same basic feature in every browser. Private browsing offers some improved privacy, but it’s not a silver bullet that makes you completely anonymous online. Private Browsing mode changes the way your browser behaves, whether you’re using Mozilla Firefox, Google Chrome, Internet Explorer, Apple Safari, Opera or any other browser – but it doesn’t change the way anything else behaves.

• HTG Explains: Do Non-Windows Platforms Like Mac, Android, iOS, and Linux Get Viruses?

  - by Chris Hoffman

  Viruses and other types of malware seem largely confined to Windows in the real world. Even on a Windows 8 PC, you can still get infected with malware. But how vulnerable are other operating systems to malware? When we say “viruses,” we’re actually talking about malware in general. There’s more to malware than just viruses, although the word virus is often used to talk about malware in general. Why Are All the Viruses For Windows? Not all of the malware out there is for Windows, but most of it is. We’ve tried to cover why Windows has the most viruses in the past. Windows’ popularity is definitely a big factor, but there are other reasons, too. Historically, Windows was never designed for security in the way that UNIX-like platforms were — and every popular operating system that’s not Windows is based on UNIX. Windows also has a culture of installing software by searching the web and downloading it from websites, whereas other platforms have app stores and Linux has centralized software installation from a secure source in the form of its package managers. Do Macs Get Viruses? The vast majority of malware is designed for Windows systems and Macs don’t get Windows malware. While Mac malware is much more rare, Macs are definitely not immune to malware. They can be infected by malware written specifically for Macs, and such malware does exist. At one point, over 650,000 Macs were infected with the Flashback Trojan. [Source] It infected Macs through the Java browser plugin, which is a security nightmare on every platform. Macs no longer include Java by default. Apple also has locked down Macs in other ways. Three things in particular help: Mac App Store: Rather than getting desktop programs from the web and possibly downloading malware, as inexperienced users might on Windows, they can get their applications from a secure place. It’s similar to a smartphone app store or even a Linux package manager. Gatekeeper: Current releases of Mac OS X use Gatekeeper, which only allows programs to run if they’re signed by an approved developer or if they’re from the Mac App Store. This can be disabled by geeks who need to run unsigned software, but it acts as additional protection for typical users. XProtect: Macs also have a built-in technology known as XProtect, or File Quarantine. This feature acts as a blacklist, preventing known-malicious programs from running. It functions similarly to Windows antivirus programs, but works in the background and checks applications you download. Mac malware isn’t coming out nearly as quick as Windows malware, so it’s easier for Apple to keep up. Macs are certainly not immune to all malware, and someone going out of their way to download pirated applications and disable security features may find themselves infected. But Macs are much less at risk of malware in the real world. Android is Vulnerable to Malware, Right? Android malware does exist and companies that produce Android security software would love to sell you their Android antivirus apps. But that isn’t the full picture. By default, Android devices are configured to only install apps from Google Play. They also benefit from antimalware scanning — Google Play itself scans apps for malware. You could disable this protection and go outside Google Play, getting apps from elsewhere (“sideloading”). Google will still help you if you do this, asking if you want to scan your sideloaded apps for malware when you try to install them. In China, where many, many Android devices are in use, there is no Google Play Store. Chinese Android users don’t benefit from Google’s antimalware scanning and have to get their apps from third-party app stores, which may contain infected copies of apps. The majority of Android malware comes from outside Google Play. The scary malware statistics you see primarily include users who get apps from outside Google Play, whether it’s pirating infected apps or acquiring them from untrustworthy app stores. As long as you get your apps from Google Play — or even another secure source, like the Amazon App Store — your Android phone or tablet should be secure. What About iPads and iPhones? Apple’s iOS operating system, used on its iPads, iPhones, and iPod Touches, is more locked down than even Macs and Android devices. iPad and iPhone users are forced to get their apps from Apple’s App Store. Apple is more demanding of developers than Google is — while anyone can upload an app to Google Play and have it available instantly while Google does some automated scanning, getting an app onto Apple’s App Store involves a manual review of that app by an Apple employee. The locked-down environment makes it much more difficult for malware to exist. Even if a malicious application could be installed, it wouldn’t be able to monitor what you typed into your browser and capture your online-banking information without exploiting a deeper system vulnerability. Of course, iOS devices aren’t perfect either. Researchers have proven it’s possible to create malicious apps and sneak them past the app store review process. [Source] However, if a malicious app was discovered, Apple could pull it from the store and immediately uninstall it from all devices. Google and Microsoft have this same ability with Android’s Google Play and Windows Store for new Windows 8-style apps. Does Linux Get Viruses? Malware authors don’t tend to target Linux desktops, as so few average users use them. Linux desktop users are more likely to be geeks that won’t fall for obvious tricks. As with Macs, Linux users get most of their programs from a single place — the package manager — rather than downloading them from websites. Linux also can’t run Windows software natively, so Windows viruses just can’t run. Linux desktop malware is extremely rare, but it does exist. The recent “Hand of Thief” Trojan supports a variety of Linux distributions and desktop environments, running in the background and stealing online banking information. It doesn’t have a good way if infecting Linux systems, though — you’d have to download it from a website or receive it as an email attachment and run the Trojan. [Source] This just confirms how important it is to only run trusted software on any platform, even supposedly secure ones. What About Chromebooks? Chromebooks are locked down laptops that only run the Chrome web browser and some bits around it. We’re not really aware of any form of Chrome OS malware. A Chromebook’s sandbox helps protect it against malware, but it also helps that Chromebooks aren’t very common yet. It would still be possible to infect a Chromebook, if only by tricking a user into installing a malicious browser extension from outside the Chrome web store. The malicious browser extension could run in the background, steal your passwords and online banking credentials, and send it over the web. Such malware could even run on Windows, Mac, and Linux versions of Chrome, but it would appear in the Extensions list, would require the appropriate permissions, and you’d have to agree to install it manually. And Windows RT? Microsoft’s Windows RT only runs desktop programs written by Microsoft. Users can only install “Windows 8-style apps” from the Windows Store. This means that Windows RT devices are as locked down as an iPad — an attacker would have to get a malicious app into the store and trick users into installing it or possibly find a security vulnerability that allowed them to bypass the protection. Malware is definitely at its worst on Windows. This would probably be true even if Windows had a shining security record and a history of being as secure as other operating systems, but you can definitely avoid a lot of malware just by not using Windows. Of course, no platform is a perfect malware-free environment. You should exercise some basic precautions everywhere. Even if malware was eliminated, we’d have to deal with social-engineering attacks like phishing emails asking for credit card numbers. Image Credit: stuartpilbrow on Flickr, Kansir on Flickr

• HTG Explains: What Does “Bricking” a Device Mean?

  - by Chris Hoffman

  When someone breaks a device and turns it into an expensive brick, people say they “bricked” it. We’ll cover exactly what causes bricking and why, how you can avoid it, and what to do if you have a bricked device. Bear in mind that many people use the term “bricking” incorrectly and refer to a device that isn’t working properly as “bricked.” if you can easily recover the device through a software process, it’s technically not “bricked.” Image Credit: Esparta Palma on Flickr HTG Explains: What is the Windows Page File and Should You Disable It?
