Obtain your locked iPhone’s UUID without iTunes

by Xavier Comments: 0

So I installed iOS 7 in my brother’s iPhone today. I had his iPhone 4 registered properly but I forgot this is a new phone. So now I have:
– A phone that is locked
– I don’t my Mac at hand, only Windows machines
– It is a pretty boring drive at 10 pm and I can’t leave him several days without a phone

Tadaaaaaaaaaa. Get it from the device manager. Just one word of advice, it NEEDS to be typed in developer.apple.com in all lower case. If you write it in upper case it will not be recognized.

It is the last string in Device Instance Path


Hello iOS 7!

Install iOS 7 – How to extract the ipsw from dmg file

by Xavier Comments: 0

iOS 7 is out. I need to give it a try, even though some people say you shouldn’t mainly because it is beta as this post from cult of mac says –> http://www.cultofmac.com/231392/why-you-probably-shouldnt-install-ios-7-right-now-opinion/

In any case this guy says you can downgrade: http://www.idownloadblog.com/2013/06/11/how-to-downgrade-ios-7-to-ios-6-1-3/

But let’s cut to the chase. I downloaded the software from developer.apple.com – you need a dev account for that. And so I have the dmg file in desktop. I go to iTunes now and it doesn’t let me select the dmg file. Crap I forgot that #1 the ipsw is inside the dmg file, #2 my Mac Book Pro is at work and #3 I don’t want to wait for tomorrow as I only have Windows on this side of the city.


Download Power Iso (http://www.poweriso.com/) and open the dmg file. The dmg file is just like a zip file in logical terms, extract the ipsw and install from iTunes.

Voila! iOS 7 installed and I am ready to suffer bugs, bad battery life and everything that comes with a beta!

Banco Nacional = Usabilidad 0

by Xavier Comments: 0

La pagina del Banco Nacional esta diseñada para ser tan inusable… es para proteger su dinero!

Es increible que haya un lapso entre ingresar una cuenta para hacer transferencia y poder hacer la transferencia. La gente tiene prisa, tiene que trabajar, tiene que seguir adelante y una transferencia hacerla de inmediato y no en dos pasos.

Esto es como hacer fila pero virtualmente. Es simplemente tonto!

(Si yo se que van a decir que es una medida de seguridad, como la vara de Java de la entrada y la tontera de cambiar de clave a cada rato. Con el token es la mejor medida de seguridad y con alertas de transferencias como el BAC. Aprendan de los que si saben hacer las cosas bien – LAFISE tambien te estoy viendo…)


This configuration section cannot be used at this path. This happens when the section is locked at a parent level

Say what?

I got this error and was pretty much clueless. It is under Windows Server 2012 and it didn’t occur in 2008

How did I solve it?

Add Application Development from the Features! Remember to add the 4.5 stuff if you need it

And then do the following in a command prompt, if required. Update to Allow on the handlers and modules section in C:\Windows\System32\inetsrv\config\applicationHost.config and remember to open as administrator

< section name="handlers" overrideModeDefault="Allow" / >
< section name="modules" allowDefinition="MachineToApplication" overrideModeDefault="Allow" / >

Best shortcut in Win8 (and Server 2012)

by Xavier Comments: 0

So yes I am annoyed too. I am one of those who thinks Win XP is the best OS from the Microsoft family… however I got to like Win7 a lot.

Now I am in Win8 (and Server 2012) and the horrible usability gives me a hard time. Only accepted a bit by the nice looks of it and speed.

So trying to make my life easier I just discovered the nicest short cut (apart from Win + C for getting the oddly name thingie on the right)

Win8… Back to Basics!

Take a deep look at Windows 8 screen.


Now think hard… What does it look like? Hint: see below


The Windows 8 screen is just the Windows 3.1 one with a blue background! Is Microsoft saving some money in design here or did they bring someone old back to the team?

Inbox Zero – How often does it happen to you?

by Xavier Comments: 0

Well basically it happened to me today! Mainly because of Memorial Day, I had the chance to clean up my inbox. However this does not mean only reading or glancing one email after another or “Mark all as read:.

Do the following (some taken from the “Getting things done” book by David Allen, just a bit modified for my needs)

– If there is nothing you can do about it, simply mark as read and let it go. This is the most difficult one of all categories because it is hard to accept that there is nothing you can actually do about it. Accept it

– If you can do something but not now and it is not that importante, then [create a task in Jira (I have my own) or some other task tracking/Kanban/post it/whatever system you use] so that you can take care of it later. This is your “do it later, not important queue”.

– If it is important, you can complete it now and it is (relatively) quick then

– If it is important but you can’t complete it now, then schedule it in your important queue. Use Kanban when possible. No more than 5 important tasks queued as then you will only be moving your mess from your inbox to your task list and this is not the idea. Scheduling is key, else you can just kick the bucket.

inbox zero

Remember never to procrastinate!

I recommend also reading the Productivity Manifesto by Nathan Barry too, which is very good however in some cases it is not possible to follow his advice. I can’t do blocks of 25 minutes of my time, else some people of my team could be blocked and waste minutes of their time. And no, I am not that important but in some cases dependencies arise and minutes count.

Finding out who is using my SQL Server 2008 database!

by Xavier Comments: 0

My last post was about taking databases offline, which if in use can be very problematic.

So before doing anything that can be interrupted if there is an open connection just run this:

CREATE TABLE #sp_who2 (SPID INT,Status VARCHAR(255),
Login VARCHAR(255),HostName VARCHAR(255),
BlkBy VARCHAR(255),DBName VARCHAR(255),
Command VARCHAR(255),CPUTime INT,
DiskIO INT,LastBatch VARCHAR(255),
ProgramName VARCHAR(255),SPID2 INT,
INSERT INTO #sp_who2 EXEC sp_who2
FROM #sp_who2
-- Add any filtering of the results here :
WHERE DBName <> 'master'
-- Add any sorting of the results here :

DROP TABLE #sp_who2

Please note that sp_who2 is undocumented by Microsoft so it might change

Taking a database offline in SQL Server 2008 and avoid transition error message

by Xavier Comments: 0

Taking a database offline is a very simple task. Right click on it and select ‘Take offline’. However, if the database is being used at the moment the action will fail and your database may remain in limbo for a (sometimes long) while.

Msg 952, Level 16, State 1, Procedure sp_who, Line 79
Database ‘UATdb’ is in transition. Try the statement later.

Try this instead:

Why I ditched Google Drive and doubled Dropbox…

by Xavier Comments: 0

Simply because Google Drive is crap. Here is a list of things it did to me:
– No LAN sync, don’t know if already fixed but it is impossible to sync 100GB on each machine, and they are next to each other in the same LAN
– Duplicated my files, when I reformatted the computer and tried to install it again. Dropbox recognizes it is the same folder and files so no need to redownload the 100GB again
– Have two computers, next to each other, and they show different file counts. I reported to Google and they said just restart Google Drive. No luck
– And last but not least, I turned if off a few days and not tried to turn it on again. Guess what… It “forgot” I had already downloaded my many GBs of files and is trying to set up a new folder. Which will duplicate my files again and again and simply just make me lose my time.


Bye Google Drive, welcome 200 GB Dropbox
