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

La pagina del Banco Nacional esta diseƱada 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…)


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.

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.

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

How to view Recent Worklogs in Jira

by Xavier Comments: 0

IMHO Jira is the best bug tracking system all around. It is very user friendly, it is extremely extensible, there are tons of add ons to customize to your needs and GreenHopper brings Agile to Jira. There are many other things worth looking for, but the one great feature where I needed some help was in the worklogs.

Basically when you have a task assigned to a developer, you would like to be able to know what kind of effort/time went into completing it. Well, there is one flaw with this plan and that is that developers need to be very disciplined into entering their hours daily.

Also, they need to make sure that they did not leave any tasks out. So for me the easiest way to make sure that a dev did fill in all of their hours properly was by adding the “Recent Worklogs” add on to their tasks dashboard.

Click here to get the add on

Check it out:

Now devs do not have any excuse of forgetting to fill in their work logs. They can see this dashboard and immediately know which day they left out.

Dropbox vs Google Drive – why I am ditching Google Drive

by Xavier Comments: 0

An image is worth a thousand words I’ve heard. Look at the following image. It is VERY SIMPLE.

I have two computers which even more are in the same network, actually sitting one next to each other (which works wonderfully in Dropbox’s LAN sync) and they are showing a different number of files, about 4GB difference.

So why do you want to use a Google Drive for syncing files, when it can’t sync files?!?!?!?!?

1071 files in one computer, 1041 in the other one!


Google: you need to try harder. Not criticizing you, but don’t release a product that works with users files and that does not work! I reported the problem here https://productforums.google.com/forum/#!msg/drive/TZ4pq4fInaY/QG3VFDTlI88J
