Metro Tiles not working after Upgrade

I found myself among a multitude of users scouring message boards trying to find out why my metro tiles aren’t working after their windows 8 upgrade.  After researching the issue I found a list of items that can cause your tiles not to work.

Screen Resolution (Must be at least 1024×768)

User Account Control (UAC must be enabled)

Permissions of the Metro Apps folder

Intel Graphics display driver

Corrupted User Account

Multiple Monitors with different resolutions

I looked over attempting to resolve any configurations listed above that would inhibit Windows 8 Metro tiles to load and was unable to resolve my problem.

I researched the issue further online still determined to not have to do a fresh Windows 8 install which was the only fix for many people experiencing this problem. Spending hours reinstalling and reconfiguring all my programs was simply not an option I wished to choose. I disabled startup items and even deleted some programs I no longer use to no avail. I went into safe mode and even created a new local admin account and much to my dismay I was about to pull the trigger on doing a fresh install.

I still forged through online posts ever more determined to find a couple more fixes I had yet to try when one person suggested to Avast users to update the program (not the definitions). I updated the program, restarted the computer and my tiles immediately starting functioning in the glory that is Windows 8. I went ahead and uninstalled Avast and began using Microsoft Security Essentials which I’ve had much luck with on all my other computers.

Surface RT Review

Okay, I’ve gone crazy. I actually stood in line opening day to buy a Surface RT!

I must say I’m in love. I bought the 64GB model with the touch cover. I even took my craziness a step further and left my laptop at home while I took a week long trip to Las Vegas for the SEMA auto show. I am happy to report I did not have the slightest urge to borrow my wife’s laptop for anything. I used the Surface to answer emails, make forum posts, and fix work issues. I even remoted into my office machine (in Oklahoma) to use SQL Management Studio to troubleshoot an issue on one of our customer sites AccreditationNow.com. All this was done flawlessly. Below, I’ll list my breakdown of random things about the Surface. Then I’ll give you my PROs and CONs list.

The Touch Cover

The touch cover is thin and uses pressure-sensitive keys somewhat like a foldable keyboard. The keyboard works great. It takes a little bit to get used to the idea that you don’t have to push very hard. It also took time to get the alignment of the keys down. However, once you adjust to it, it works great. Also, unlike my laptop, I don’t find myself hitting the touch pad and moving the mouse all over the place. I do not know if this is the software knowing I don’t mean to or the placement of the touch pad.

The Kickstand

The kickstand is a great addition. If you have the nifty folding iPad cover on your iPad, you get a sort of kick stand in portrait mode, but if you are watching a movie or anything more suited for landscape, you have no alternative.

The Surface’s kickstand is at what seems to be the perfect angle. It sits on my lap just fine, and I can use it like a laptop if I want to. Using it this way is by no means excellent, but it is doable. Plus it’s light enough that I can sit on the couch with it like that through several TV shows while tinkering away without issue on message boards or writing emails.

The Software

For some reason, it is surprising how well the new OS is. It shouldn’t be. Microsoft has been making software for over 30 years, so they have some experience in this area.

At first glance, I was like everyone else wondering how I would live without a start button and what this new tile interface was. Technically, people using an Xbox have been seeing this interface for quite a while.

There are four gestures you simply must get used to right away.

When holding the device in landscape with a hand on each side, swipe your thumb from the right side to bring up the charms bar. This bar has search, settings, start, share and devices buttons.

  • searches the current application if possible or the entire machine.
  • gives you all the sharing options to share what you’re looking at with friends.
  • takes you back to the start screen.
  • lets you duplicate the screen to any attached display like a projector.
  • lets you see the settings or options for the application you are in.

Swipe your left thumb over from the left and you can easily switch through applications that are currently open. Bring your thumb back but not off the screen, and a tile display of all applications opens up so you can pick one.

Swipe a finger from the top down to the bottom, and the app you are in closes. Yeah, it closes, not hides until you manually close it later!

Then we have multitasking like no one else has done before. Not only does the OS seamlessly multitask, it lets you split the screen between apps. I had firsthand experience enjoying this when I was emailed a security update for vBulletin saying there was a YUI exploit and that I needed to do steps 1 through 6. I simply slid the email client over to the left and opened up IE on the right, followed the instructions, and fixed the bug in two forums we maintain for our customers.

So overall I’m extremely happy with my purchase, and I don’t feel bad about ditching my Galaxy Tab 8.9 at all. Now for the pros and cons list:

CONS

I cannot run native x86 apps on the Surface RT. I knew this going into it, but it really sucks. My desktop and my tablet look and function the same now except that programs like Management Studio or Visual Studio simply won’t run. I have to remote into another machine to accomplish that stuff. Granted I don’t need or want to do that stuff on my little tablet all the time, but it would be nice to be able to without being forced to remote in.

The app store is limited on apps. There are tons of apps, and overall there are plenty to sift through. However there are not as many as the Google Play store or Apple’s App store.

It is somewhat heavy. I’ve been saying the iPad 3 is a joke because it’s thicker and heavier than our iPad 2, and the ‘upgrades’ make no real difference to the average person. All the Apple fans took the increases and didn’t even remember the original goal of the iPad to be the thinnest, lightest it could be. So Microsoft rolled with it, and this thing is a tad bit heavier than the iPad 3. Compared to the iPad 2, it’s night and day, and you think, ‘Wow, that is heavy’ Compare it to the iPad 3, and you don’t really even notice a difference unless you want to be picky.

Randomly, the keyboard did not work when I wanted to use it. I had to unplug it and re-attach it before it would come back to life. Only happened twice, but it did happen.

The charging port is at an angle which makes plugging the magnetic adapter to it a bit of a skill versus the entire goal of a magnetic adapter to make attaching easy. This thing would have been better if it were a simple USB style connector. HOWEVER, being magnetic means it won’t break if it’s ripped off, and that must be the only real goal of this connector in Microsoft’s mind.

PROS

I can do anything on it I can do on my desktop. I have a mouse and a full keyboard. It’s truly liberating versus your average tablet. You just don’t realize how much you miss being able to actually DO something versus just read the web.

The app store has an efficient layout and is easy to use. All the primary apps I like to use such as news360, Newegg, or Kindle are there ready to go. Even the more popular apps like Angry Birds, Skype, Epicurious, Netflix, Hulu, WeatherBug and the list goes on. No shortage of really big name apps we all need.

The other app stores having 250,000 apps means there are thousands upon thousands of apps I never even knew existed, so there is a perk to an app store that has a limited number of apps.

It comes with a pretty complete version of Office. There are some limitations, like the use of Macros and what not, but for your average user, this is a sweet deal. Office alone is half the price of the machine.

It lasts on the battery ALL DAY just like they said. No matter what I did with this thing, I played games, watched Netflix, worked, and it never ran out of juice. Today I didn’t use it much at all; I just read the news this morning, and it sat on my desk all day until I needed to reference something. It is still sitting at 94% battery life.

If you push it hard with games, it doesn’t get hot like other devices. I’ve never felt it get warm.

It has a USB port! I’ve already plugged my flash drive in a couple times to copy music and files to it. You can utilize the port like any other USB port and plug just about anything into it, and Windows has drivers.

It finds ALL the printers and devices on my network like a normal windows machine, and I can actually use them! Unlike Android and Apple which pick and choose which devices you can access or print to, this device lets you do what you want just like you can on your normal Windows desktop.

The cameras have a little LED to let you know when they are on. This is small, and it has been like that on desktops for years. However all my phones and tablets, whether Android or Apple just forgot that touch. I never know if anyone is accessing the camera. The Surface let me have my privacy back.

Speaking of privacy, the Surface has cookie tracking turned off by default. It has EVERYTHING in the privacy section turned off by default. Microsoft took note and chose to let the user decide what information they track.

Skydrive, contacts, email integration is excellent. Everything just simply works. By utilizing my Microsoft account, it automatically imported things like my desktop background from my desktop and my Wi-Fi settings from my laptop, so I didn’t have to re-enter all that. This can easily be turned off via your Microsoft Live account though, so don’t worry if you don’t like it.

iPhone 5 To Upgrade Or Not To Upgrade

Hello World! Joel from Skynet Solutions here. This is my first ever blog post, so I thought I’d use the opportunity and discuss my thoughts on purchasing the newly released iPhone 5. Unless you spend most of your time in the unexplored regions of the rainforest, you already know about the release of Apple’s new iPhone 5. And just like me, there are probably a lot of iPhone fans wondering if they should go for it and upgrade now.

My current phone is an iPhone 4, which doesn’t have some of the features of the “4S” like iCloud integration or being able to ask Siri the meaning of life. But my “4” is a great product that continues to serve me well, and since I seem to be immune to hype, I didn’t upgrade when the “4S” came out.

Now, I love playing with new gadgets, but I am also very aware of the realities of new product launches. I haven’t installed iOS 6 on my current phone yet for the same reason that when buying a car (new or used), I never buy the first model year after a fresh redesign. There are ALWAYS bugs to work out of a new product. This is especially true in the world of mobile phones where the pressure to be first with the latest innovations is tremendous. So when a new iOS comes out, I always wait a while before updating.

Exhibit “A”: Steve Jobs’ replacement Tim Cook just put out an apology for the problems with the new Maps app. As you’ve probably already heard, the Google-based Maps has been replaced by a homegrown app developed by Apple. There have been complaints about numerous mapping mistakes and misinformation about locations (much like when Google began their map project a few years ago). Apple is playing catch up, so it will take time to perfect it. If they can deal with the problems, this new version provides turn-by-turn directions with big, easy-to-read onscreen graphics, it re-directs you to alternate routes based on traffic, works when the screen is locked, and supports Siri, so it should be a real asset in your car.

About the problems, Cook also surprisingly said: “While we’re improving Maps, you can try alternatives by downloading map apps from the App Store like Bing, MapQuest and Waze, or use Google or Nokia maps by going to their websites and creating an icon on your home screen to their web app.” I bet that was a tough pill to swallow for a guy attempting to follow a predecessor like Steve Jobs. The new Maps app was obviously released too soon. Strike one. According to Cook, they are already working “non-stop” to fix the issues. And I’m sure they will. They can’t afford to squander their biggest asset, the loyal hoards of Apple fans.

Does this mean the iPhone 5 is no longer a consideration for me? Of course not. There have been similar iPhone problems in the past, such as dropping calls if you touch the wrong spot on an iPhone 4. Oh wait, isn’t that the phone I have now that I like so much?! In other words, this Maps problem too shall pass.

So for now, I am going to postpone the decision to buy. And in the meantime, I will look in-depth at some of the new features. But that’s a blog for another day.

Samsung Galaxy SII SGH-I727 ICS Update

Finally, the update I’ve been waiting for comes! Although it’s quite unfortunate it has come right after I’e now got my sights set on Jelly Bean, and now that Ice Cream Sandwich is yesterday’s news. Hopefully Samsung and other manufacturers will pick up the pace in releasing Android updates.

I used Samsung Kies to do the upgrade. I do not think this was an over-the-air upgrade; I just decided to check Kies, and it had an update.

Previously, Kies would say the firmware upgrade was not supported on this device. I upgraded Kies, and it instantly said there was a firmware upgrade for my phone.

Unfortunately, my phone was only at 30% battery. The software will not let you upgrade unless the phone is 100% charged. Use your A/C charger; it takes FOREVER to charge via USB 2.0.

Here is a list of feature updates to ICS:

A few of them are actually already available via the Samsung device and software. I guess Google decided having some of these features (ie. quick responses for incoming calls, the home, back, and current apps buttons) always available was a great idea. It is still pretty cool that those buttons are on the phone at the bottom already, not wasting screen space – so no real upgrade there. For other model phones, I imagine this is a HUGE upgrade.

Here is a list of things I noticed right away:

1. The phone is CRAZY FASTER. I mean WOW, I thought it was quick and fluid before. This is insane. It is like I added ram and a faster processor. Maybe it will change overtime, but so far I’m impressed!

2. Several apps instantly downloaded updates.

3. The default widgets like Google Search, Facebook, and AccuWeather were all added back to my home screen.

4. The widget on the home page that lets you turn off Wi-Fi, Bluetooth, etc. is no longer a single row with the button letting you see the rest; it is two rows, now letting you see it all.

5. The display of available widgets you can add is much cleaner looking. A+ job on this – seems planned versus thrown together like before.

6. The layout of the settings section is completely different. Again, this is laid out like there was thought put behind it instead of just a list of everything. Excellent upgrade! Wi-Fi is right at the top, and you can change what you are connected to with one touch instead of two touches into the menu. Battery status is also another one right there instead of having to go to About Phone then Battery Usage. Instead of having to do three steps to change your background wallpaper, you simply touch Display, and then the options you really want are right there. No more digging into settings to change the simple stuff.

7. There is now a nice security section. You can use Face Lock to let facial recognition unlock your phone. Also you can encrypt the entire phone or just the SD card.

8. Big changes to the Camera interface. It has tons more settings. You can tap and hold and then pick from 16 settings from shooting mode, timer, GPS tag, to white balance. You can also modify what four you see right away without tapping and holding on the initial screen.

9. Last but not least, Samsung Voice Talk. It is basic voice functionality like text messaging, calling, navigation, searching, etc., and it seems to work really well. I’ve set up my search button hold event to load this and auto listen.

All in all, I’m much happier with this update than I expected. All the new tweaks to the interface and the performance increase are excellent. I cannot wait to get my hands on a Jelly Bean interface!

Windows Secure Web Patch Virus

Windows Secure Web Patch is a nasty new piece of malicious malware. Once your machine is infected, it locks you out of your anti-virus, internet, and task manager, even in safe mode. It also claims to show you tons of infections on your computer and offers to clean them for a price. Under no circumstance should you buy this rogue security software.

After looking around the web, I found a great article providing information on how to remove this from your machine. There is an additional minor step required. I’ll post below how you can remove this from your machine within 15-30 minutes, depending on the speed of your computer.

Step 1: Go to Command Prompt – From the desktop, click the start button, and then in the run field – type command

Step 2: Kill the Secure Web Patch Process Type: taskkill/IMprotector-scxb.exe /F

Step 3 : Open Internet Explorer and go here: http://malwaretips.com/blogs/windows-secure-web-patch-virus/

Step 4: Scroll down to step 3 of theirs and continue the process.

Virtual Infrastructures Which is Faster NFS or iSCSI

Part 1. The setup

In my current position I am responsible for the support and management of all aspects of my employer’s IT infrastructure. This ranges from firewalls and network switches to servers and printers to phones and desktops. While my employer is a not-for-profit agency we have been able to implement an enterprise-class infrastructure thanks in part to several grants and donations we have received. It is my hope to make these enterprise-class methods & best-practices available to small-businesses and educational institutions at a fraction of the cost through the use of user-friendly open-source software.

At the core of these best-practices is the use of virtualization technology which has numerous benefits such as:

consolidate under-utilized physical servers to reduce hardware, electricity, and cooling cost

isolate applications to individual virtual machinesto prevent incompatibility issues

run multiple operating systems utilizing a single hardware platform

If you have only one virtual machine host server then local storage is sufficient however if you have several servers working in conjunction with each other then you need some sort of centralized storage to utilize those servers to their fullest potential. Centralized storage usually consists of a SAN or NAS that makes disk space available to the servers using the NFS, iSCSI, or Fiber-Channel protocols.

I have not yet had the opportunity to work with Fiber-Channel due to the costs associated but for the past few years I have having been using the NFS & iSCSI protocols in virtual infrastructures. There are numerous discussions on the Internet stating that one is better than the other but few have gone into the details as to why.

Recently I have been involved in several discussions with some of my peers regarding the different filesystems (EXT3, EXT4, UFS, ZFS) available in today’s mainstream Linux distributions. Each has its own set of requirements, benefits, and drawbacks. As a result of these discussions I decided that I wanted to see for myself which protocol and filesystem provided the best centralized storage performance for virtualization host servers.

For hardware, my test environment consists of a Supermicro Xeon 3450 based server with 16GB ram and a 500GB hard drive connected via cross-over cable to an HP Proliant N40L Microserver with 8GB ram, a 250Gb hard-drive, and two 1.5TB Western Digital Black hard-drives. For software, the Supermicro server is running VMWare vSphere 5.0 and the HP server will serve as the centralized storage running FreeNAS, CentOS, Ubuntu, & OpenFiler. The servers are connected via dedicated network cards and a cross-over cable to eliminate the possibility of a network switch’s backplane bandwidth affecting performance.

After a bit of research I came up with four procedures/applications that I wanted to use that would consistently test each of the protocols and filesystems on the different distributions. The applications are installed in a Windows XP virtual machine hosted on the Supermicro’s local datastore but ran on a secondary thin-provisioned 80GB virtual hard-disk that is hosted on the HP’s datastore.

  1. Use the vSphere client to copy a 3.05GB ISO file from the Supermicro’s local datastore to the HP’s datastore (and vice-versa) and time how long it takes.
  2. Run ATTO Disk Benchmark v2.47 inside the virtual machine with all of the default settings. This program transfers data ranging from .5KB to 8MB both to (write) and from (read) the secondary virtual disk and measures the transfer rate.
  3. Run Intel NAS Performance Test v1.7.1 inside the virtual machine with all of the default settings. This program is capable of running around 12 different benchmark tests on the secondary virtual disk.

HD Video Playback, 2x HD Playback, 4x HD Playback

HD Video Record

HD Playback & Record

Content Creation

Office Productivity

File copy to/from NAS

Dir copy to/from NAS

Photo Album

4. Run Iometer v inside the virtual machine using the procedure and config file provided on http://technodrone.blogspot.com/2010/06/benchmarking-your-disk-io.html. Iometer creates a 50GB file on the secondary virtual disk and the following tests are ran for 5 minutes each with a 2 minute lead up in an attempt to produce more “real world” scenarios.

4K; 100% Read; 0% random (Regular NTFS Workload 1)

4K; 75% Read; 0% random (Regular NTFS Workload 2)

4K; 50% Read; 0% random (Regular NTFS Workload 3)

4K; 25% Read; 0% random (Regular NTFS Workload 4)

4K; 0% Read; 0% random (Regular NTFS Workload 5)

8K; 100% Read; 0% random (Exchange Workload 1)

8K; 75% Read; 0% random (Exchange Workload 2)

8K; 50% Read; 0% random (Exchange Workload 3)

8K; 25% Read; 0% random (Exchange Workload 4)

8K; 0% Read; 0% random (Exchange Workload 5)

8K; 50% Read; 50% random (Exchange Workload 6)

64K; 100% Read; 100% sequential (SQL Workload 1)

64K; 100% Write: 100% sequential (SQL Workload 2)

64K; 100% Read; 100% Random (SQL Workload 3)

64K; 100% Write: 100% Random (SQL Workload 4)

256K; 100% Read; 100% sequential (Backup)

256K; 100% Write100% sequential (Restore)

Ideally each of the above tests would be ran a minimum of three times and the results averaged to get the final results for each test for each OS, filesystem, & protocol. However doing so would have taken way longer than I can spare for this project so each test was ran just one time.

I’m not going to go into considerable detail about each of the operating systems I’m testing as each could be a full article in itself. Instead I’m going to just cover the basic setup of each and focus more on the results.

Part 2  FreeNAS 8

FreeNAS 8.0.4 x64 ZFS NFS

The first operating system tested was FreeNAS 8.0.4 x64. I installed the operating system to the 250GB hard-drive and created a ZFS mirror of the two 1.5TB hard-drives. A secondary subnet IP address is assigned to a dedicated NIC that can be accessed from the storage NIC on the ESXi host and a NFS share is created on the ZFS mirror. The NFS share is mounted inside of ESXi and the first set of tests are began.

  1. Copying the 3.05GB ISO file to the NFS datastore took 16m 35s for a throughput of 3.04 MB/s. Copying the ISO from the NFS datastore took 2m 16s for a throughput of 22.71 MB/s.
  2. Screen capture of the ATTO benchmark results:

3. Screen capture of the Intel NASPT benchmark results:

4. Summary of the Iometer results after taking approximately 4 hours to create the 50GB test file:

It would appear that the overall results show good read performance but slow write performance for FreeNAS 8 running NFS via a ZFS mirror.

FreeNAS 8.0.4 x64 ZFS iSCSI

Next the NFS share is removed from ESXi and FreeNAS and replaced with an iSCSI extent. Unfortunately FreeNAS 8 doesn’t support device extents on a ZFS mirror so a file extent had to be used. A file extent is simply a single file that is shared and looks like a single disk to the ESXi host. This is not recommended in production environments because if something happens to that file all of the virtual machines could be lost. All other settings remain the same as the first test.

  1. Copying the 3.05GB ISO file to the iSCSI datastore took 49s for a throughput of 61.63 MB/s. Copying the ISO from the NFS datastore took 2m 10s for a throughput of 23.23 MB/s.
  2. Screen capture of the ATTO benchmark results:

3. Screen capture of the Intel NASPT benchmark results:

4. Summary of the Iometer results after taking approximately 30 min to create the 50GB test file:

It would appear that the overall results show a slight drop in read performance but considerable improvement in write performance for FreeNAS 8 running iSCSI via a ZFS mirror.

FreeNAS 8.0.4 x64 UFS NFS

Next the iSCSI file extent and the ZFS mirror are deleted and replaced with a UFS mirror and NFS share.

  1. Copying the 3.05GB ISO file to the NFS datastore took 58m 28s for a throughput of .86 MB/s. Copying the ISO from the NFS datastore took 3m 4s for a throughput of 16.41 MB/s.
  2. Screen capture of the ATTO benchmark results:

3. Screen capture of the Intel NASPT benchmark results:

4. Summary of the Iometer results after taking over 24 hours and crashing FreeNAS to create only 30GB of the 50GB test file:

FreeNAS 8.0.4 x64 UFS iSCSI

Next the NFS share is removed from ESXi and FreeNAS and replaced with an iSCSI extent. Again, since FreeNAS 8 doesn’t support device extents on a ZFS mirror a file extent had to be used.

  1. Copying the 3.05GB ISO file to the iSCSI datastore took 1m 26s for a throughput of 35.12 MB/s. Copying the ISO from the NFS datastore took 2m 14s for a throughput of 22.54 MB/s.
  2. Screen capture of the ATTO benchmark results:

3. Screen capture of the Intel NASPT benchmark results:

4. Summary of the Iometer results after taking approximately 30 min to create the 50GB test file:

FreeNAS 8 Summary of results

In order to get a better look at each of the test results I put them all into LibreOffice Calc so that I could see each test side by side and bolden/underline the top performer of each:

  1. Summary of the copy ISO test for each filesystem and protocol:

2. Summary of the ATTO test for each filesystem and protocol:

3. Summary of the Intel NASPT test for each filesystem and protocol:

4. Summary of the Iometer test for each filesystem and protocol:

Based upon each of these summaries it would appear that ZFS is definitely the winner between the two filesysems. It is interesting to note that if the need for a datastore with faster reads is greater then NFS is the way to go but if faster writes are needed then iSCSI is the way to go. However in a production environment I can not recommend the use of iSCSI in FreeNAS unless a hardware raid solution is used for the ZFS drivespace so that file extents are not used.
