If you think about getting something from Packt – this is the right time: http://bit.ly/1r5fCms

You can get all the stuff for $5.

I, personally, suggest to get these two from Packt:

and

rxvtimg.C error: ‘PictOpDifference’ was not declared in this scope

If you experience the issue with following error:

rxvtimg.C: error: ‘PictOpDifference’ was not declared in this scope

you can overcome it by commenting out following part in config.h

/* Define to enable xrender support */
/* #undef XRENDER */

Update:

Optionally, you can disable transparency by setting following settings in config.h

/* Define if you want your background to use the parent window background */
#undef ENABLE_TRANSPARENCY

#error Blitz is configured with –enable-threadsafe

#error Blitz is configured with --enable-threadsafe, 
but no compiler thread support is found. 
Did you forget, e.g., "--pthread"?

This message might be quite confusing, as typically, you will blindly take “–pthread” and pass directly into g++. However, g++ have other option :)

-pthread

DDD – compilation fails: strclass.C: In function ‘std::istream& operator>>(std::istream&, string&)’: error: ‘EOF’ was not declared in this scope

If you have an issue while compiling DDD

strclass.C: In function ‘std::istream& operator>>(std::istream&, string&)’:
strclass.C:1546:35: error: ‘EOF’ was not declared in this scope

Go ahead, and thanks this guy http://garricksblog.blogspot.com/2012/02/mid-terms-and-build-errors.html.

quote: “It turns out that the constant EOF was not probably declared by including stdio.h. So I went ahead and added that in:

I owe you a beer ;)

Theme, you can fall in love with :)

    Recently, while reading Getting started with tmux, I have read about really nice theme -“SOLARIZED”. You can find it here: http://ethanschoonover.com/solarized

    There is a predefined profile for iTerm, so you are good to go straight after downloading it. Highly recomended.

Getting Started with tmux by Victor Quinn, J.D.

tmux

Summary: short and straight to the point

This book is one of these short manuals where you get exactly what you need. Simple and straightforward explanation of the tool, helpful examples, and real life cases that show how can you improve with tmux with really not too much effort.

You are literally guided step by step in each case and it is really hard to get lost. In my opinion, samples do really reflect activities that most people do while working with ssh. It is not just a random set of advices taken from the internet.

And, you get this nicely organized Appendix with all the key bindings used through out the chapters.

I would recommend this one for anyone who haven’t heard about tmux yet, but works with ssh a lot.

Modern Perl Best Practices by Damian Conway

bkt_perl_modern_practices

Summary: Highly recommended

Whether you want to watch this video heavily depends on how much Perl do you use, and how much do you appreciate good advices.

If you work with Perl on day to day basis, and you want to improve by applying some of the good practices, really consider this one. Damian Conway goes over variety of topics here and presents best practices. Of course the term best is heavily biassed here, as author shows what is the best in his opinion. It not always must be the case, but still, huge part of the video shows you really good practices, while remaining one presents almost best practices.

What is really worth to watch is the approach to certain topics and, to my surprise, some of the ideas can be easily adapted to Python as well. Of course you can’t get them directly, but concepts and ideas are really worth taking them into Python instead of Perl. This, for example refers to hash map manipulations, passing arbitrary number of arguments via dictionary, naming conventions, data layout in the code, code formatting and documentation, etc. Even though you won’t be able to apply these rules directly, you will be still able to follow them.

As for perl itself, there were few surprises in the video that caught my attention (I am just a casual perl developer). I was caught by some builtins (e.g. enumeration), I was surprised by some conventions that can do you lots of harm when incorrectly used (e.g. scalar vs. list context), and in general it was real eye-opener in many cases (but that might be the result of my rather reduced activity when it comes to day to day usage of language).

If you ask about lecture delivery, video quality, and material preparation – they are simply top-notch.

As for the best practices themselves, these are not defined by simple set of rules, but your attitude towards excellence in what you do – as Damian points out at the end.

Highly recommended.

How to import Safari bookmarks into Opera 25

It is not an easy task. Unfortunately, it doesn’t work out of the box, but you can cheat Opera a little bit.

So, to get all bookmarks from Safari inside Opera 25 you have to use Chrome :) Install Opera, install Chrome.

After starting Chrome, it will ask you to import bookmarks from Safari – agree to do this.

Then, open Terminal window and execute following command

cd ~/Library/Application\ Support/com.operasoftware.Opera
cp ./Bookmarks ./Bookmarks~
cp ../Google/Chrome/Default/Bookmarks .

And, that’s it :)

You have all your Safari bookmarks inside Opera.

NOTE! Opera 26 – 26.0.1656.24 gives you the option to import bookmarks directly from Opera -> Import Bookmarks and Settings … !!

Keynote – disable snap to objects

Sometimes, it’s quite frustrating when you can’t place object exactly where you want it. And that’s the result of “snap” feature in Keynote. You can easily overcome that by clicking Command button. Take a look below.



Diablo 3 – crashes at OS X and freezes my Mac

If you have experienced the issue with Diablo 3 completely freezing your Mac, take a look at file inside /Application/D3Debug.txt.

In my case, there was this issue that files were corrupted. You can tell that by examining the D3Debug.txt

2014.11.12 00:38:24.407071158	ERROR: Failed to validate 
file (Appearance\a3dun_Keep_Cart_A_Breakable.app). Details:
F9E0777B147CBC680FB8E6358613B470 778840 1

Data_D3\PC\MPQs\Cache\base\patch-base-26451.mpq

2014.11.12 00:38:24.407202563	ERROR: [Data Validation Failure] 
Diablo III was unable to validate core data files.

What you can see here is that one of the patches is corrupted. In order to fix that, you have to go inside

/Applications/Diablo III/Data_D3/PC/MPQs/Cache/base

And remove mentioned patched file + anything that is newer than that. In my case, it was: patch-base-26451.mpq file.

After removing broken patches, application downloaded all the data once again and this time it was just fine.
