Problems installing KB2770917 in Windows 8

I was having some problems installing Windows 8 KB2770917 update, it stopped at 15% and then it rolled back the installation. As being diagnosed as having CUD (Cumpulsory update disorder) I found a solution in Microsoft site:

http://answers.microsoft.com/en-us/windows/forum/windows_8-windows_update/i-cannot-install-windows-update-kb2770917/e2189ae7-e86a-4bf2-931a-d985b25ad950

Run msconfig (Windows+R, msconfig)
Go to Services
Select Hide all Microsoft services
Disable All non Microsoft services
Setup KB
reboot
run msconfig again, Services and  Enable all Services
reboot again to start the services
and it worked for me.

How to find out if you are running 32-bit or 64-bit version of MySQL

I neeeded to update MySQL, installed using an automatic installer, so having passed a lot of time after I did the installation, I needed to know which version of MySQL I was running.

I found two was:

Inside MySQL console:

mysql>show global variables like "version_compile%";

The answer was:


+-------------------------+-------+
| Variable_name           | Value |
+-------------------------+-------+
| version_compile_machine | x86   |
| version_compile_os      | Win64 |
+-------------------------+-------+


As I understand this means that I am runnig x86 version of MySQL on a Windows 64 machine, so the answer for me is that I am running the 32 bit version.

x86 32 bits
i686 32 bits
x86-64 - 64 bits

The other way to get this information is using the command prompt, in your mysqld.exe location run:

mysqld --version

and you will get mostly the same information. As I understand Win64 refers to the machine I am running, and the other value to the mysql version.

http://localhost/sys/en/classic/login/login page not found installing ProcessMaker

I have been trying to install ProcessMaker using Wamp to avoid having several installations of MySQL, Apache and PHP. After serveral attemps I kept getting errors and could not make it work.

My goal was to setup ProcessMaker in the following way. I tried using an alias instead of a Virtual Host.

http://localhost/ProcessMaker

As it turns out, it cannot be done that way. Whatever you do, you will not make it work (I guess there is a way, but yet have to find one, and would be not supported).

The correct way would be something like

http://ProcessMaker.localhost

This would requiere changes in my hosts file and I guess I will have to go that way. The reference I found was this:

http://forum.processmaker.com/viewtopic.php?f=5&t=249

Hopes to save you some time.

Problems after upgrading Wordpress

I've have this problem a couple of times after upgrading Wordpress to the latest version. Trying to go to the admin page in Wordpress, I received the message that the page does not exist with the following line in the address bar, after my site name


http://..../wp-admin/upgrade.php?_wp_http_referer=%2Fwp-admin%2F

I do not remember what I did the last time, I believe I reinstalled the update from Goddady's site. But this time around it did not work. After doing some research I found this at the Wordpress site:

http://wordpress.org/support/topic/upgrade-to-34

The post by chowsir had the solution for me. The way I see it it is very simple, if you read the line. The page that does not exist is upgrade.php, so I look into my wp-admin directory, and it is true, the file is not there, there are other files with similar names update.php, upgrade-functions.php, update-core.php, but the file upgrade.php is not there, at least, not anymore.

Go to http://wordpress.org/download/ and download wordpress again
unzip the files and go int wp-admin folder
copy the file upgrade.php to your site.

I received a message about the need to update the database, gave it a click, and now is working again.

Hope it helps, if not, now I know what to do the third time around.

Problem with USB drivers

Having messed up my USB drivers, doing things that shouldn't be done on Windows I ended up with the following problems:

1. USB Hubs (specifically a Belkin hub first, and all including internal notebook hubs) were not recognized as such, I made them work as USB Root Hubs installing the driver manually, but with problems.
2. Kindle Fire not recognized as a external drive, the was no way I could find a driver for it.
3. Livescribe Echo Pen not being recognized, even installing the driver manually with an error 257, and connecting and disconnecting by itself every 5 to 10 seconds.


Being desperate, I decided to remove all Universal Serial Bus controllers from the "Computer Management" or Device Manager in Windows, using the reasoning, how worse can this be. To my surprise, nothing was now recognized, even when I re-installed the USB Host Controller with the original Chipset drivers from Intel/Lenovo.

Then, something magic happened, I found an article in the Microsoft Support site:

http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/trying-to-install-usb-hubs/e46ebc32-c968-4a24-ad86-8399ae91f95b?auth=1

Basically it suggested updating the driver software from the following location "C:\windows\winsxs" as it turns out, this is very important windows folder, that I wasn't aware of, it is huge, and has every version, of everything that has been installed in your machine. I first updated the drivers for the USB hub, and magically, everything started to fell in place, it took a while, maybe 15 minutes to install the USB hub, but then, everthing started to appear, even the Kindle Fire as an external drive. The only thing missing was the Livescribe Echo, but again, I updated from drivers to c:\windows\winsxs instead of the Echo drivers location (C:\Program Files (x86)\Common Files\Livescribe\PendriverV2.2). You don't even have to look for a directory inside of it, just choose the complete folder. One of the internal USB hubs kept being recognized as a unknown device, but working, I updated it also form the same location.

At the end everything returned to work. Hope this helps if you run in the same of similar problems.

Installing Android ICS on Amazon Kindle Fire

I love my Kindle Fire, it was a good buy, and worked great. Rooting is a must, as you cannot buy or install much on it if you do not have an US Bank issued credit card. But after getting a iPad, it seemed liked getting behind. Having Android 4.0.4 Ice Cream Sandwich on my Galaxy S, I knew the problem was not the device, but the OS version. I tried installing ICS a while ago, but could not run Netflix, and YouTube, almost everything else worked, but the video part was important. So after a short while, I went back to the Kindle OS (Android 2.x, with a "you cannot get lost" interface).

But reading about the developments in ICS, and that video is now supported, I decided to try again. The process is real simple, but risky. For a couple of hours, last time I tried it, I ended with a bricked kindle. But in the end it all went back to normal.

The first step for me was installing Kindle Fire Utility:

http://forum.xda-developers.com/showthread.php?t=1399889

The instructions are there, and with this took, you can root your Kindle, once rooted you can install TWRP Recovery. With this software, you can also return your Kindle back to stock, so don't worry about "much" leaving your Kindle useless. There is also an Kindle "unbrick" utility available somewhere.

Then you can install a new ROM, the one I found was here:

http://forum.xda-developers.com/showthread.php?t=1591850

I have tried 05-12 Kernel #10 full stock CM9 and it is working like a charm.

You will also need Google utilities, that have to be installed after that, the place I have downloaded them, and it works great is:

http://goo.im/gapps/

ics-20120429 version has worked for me.

In general it works very good, just like any other tablet running ICS. Netflix and YouTube work, as well as Zinio, and Kindle. Google new Play Store works, Google Chrome beta and many more. The interface is nicer that Amazon Kindle library style interface.

You can also change the language on you Kindle, specially to avoid the annoying corrections.


Problems found:


I will say there are three problems affecting me, right now, none of them have convinced me to return to Amazon old interface.

  • Some magazines are not available in Kindle for Android client
  • I could not find Kindle 100 free books list , strange as it works on ipad, but you can use Amazon full website list: Kindle Free "Bestsellers" 
  • Kindle cannot be accessed through the USB port, there is no option to share the USB to you computer, the best work around is to boot the Kindle and use the USB mount in TWRP Recovery
  • Battery would discharge in around a day, the battery life is kind of OK, maybe around 4 hours using video, but when not use, the battery would discharge anyway. Charging indicator and lights do not work either.
  • Microphone still does not work for me, but if you program requires audio to launch, it will work, but input audio will not be usable.
Bottom line:

If you use your Kindle Fire outside of the US, and use you Kindle mainly in your house or office, you will have a better experience tranforming it to and ICS Tablet.

Ubuntu does not recognize windows partitions

Trying to install Ubuntu 12.10, the Ubuntu installer does not recognize that a Windows partition exists. Looking around, it seems kind an usual problem, but with not many real solutions. Browsing around I found an utility to "fix"my partition table. My partition table was working great in Windows, so "fix" is more appropriate than fix.

http://www.rodsbooks.com/fixparts/

Being myself I Windows person, I selected the Windows version of the program:

to run it I used

fixparts 0:

The first thing I got was:


NOTICE: GPT signatures detected on the disk, but no 0xEE protective partition!
The GPT signatures are probably left over from a previous partition table.
Do you want to delete them (if you answer 'Y', this will happen
immediately)? (Y/N):

Now I understood the problem. I used this disk to install MacOS, and the leftovers made the problem. I selected, Y (for yes) and then w to save and exit. Booted Windows again to see everything was OK, and then reran the Ubuntu installer. Now it recognizes my partitions. Now I might even try to install MacOS again, instead of Ubuntu.

The solution to this problem came from:

http://ubuntuforums.org/showthread.php?t=1712153

So if you do not understand what I did, maybe you will from there.
