Last year I bought an Amazon Kindle Fire on Black Friday in shopping season. The 7-inch tablet costs about 50 Euro at that time and was pre-installed with all of Amazon services and apps. Of course, we can’t expect a powerful tablet at that price level but the table’s really good for daily activities such as web surfing, listening to the audio book or playing small games. I really like it but the apps and services from Amazon. The advertisement on lock screen doesn’t disturb me at all, but the unnecessary apps from Amazon do make me really annoyed. Therefore, I decide to flash the tablet with CyanogenMod to get rid of all stuff from Amazon.
I’m using a shared hosting service provided by Bluehost and have many websites on this account. Last month, November, my brother wrote me that he received a lot of traffic to his website although he didn’t update anything. He worried that maybe a web shell backdoor was injected into his website because he used some null-ed plugins and templates (My bro, please don’t use any null-ed components anymore, buy commercial components or use free ones instead). If his website got attacked, my blog will be also on target because we use same account for both websites. I decided to make a short analysis of Apache Access Log (AAL) to check if a web shell backdoor is installed on my shared hosting.
UPDATE: For Mac OS X Sierra please follow this post How to install Mac OS X Sierra 10.12 on VirtualBox?
Years ago I wrote a post for installing Mac OS X on VirtualBox. At that time, the version of Mac OS X was 10.7.3 Lion. The installation may not work with current version of VirtualBox anymore. Therefore, I would like to make another post for updating this hack. This time, we’ll use VirtualBox 4.3.26 for hosting Mac OS X Yosemite 10.10 in Windows 8.
One year ago I encountered a problem relevant to create a shortcut for relative path. I had to deliver a software package to customers over DVD. The app is kind of archive. It should run live on DVD, connect to a read-only SQLite database (also on that DVD) and display data in read-only mode. It’s pretty easy to deploy such software but when I copy files into a sub folder and create a shortcut to program on its parent folder. The shortcut won’t work on other machine because it uses absolute path and the icon won’t also appear. So a consideration raised if I should develop a Start.exe just to start the program or use some tricks to create a same thing.
Last month I ordered a Raspberry Pi for learning purpose. I heard a lot of about this mini computer and waited until its 2nd generation comes to market to get one. Depending on purposes, there are a lot of kits for Raspberry Pi in the market (from starter to professional). I myself don’t know what I can do with this mini computer therefore I just buy at least hardware first (listed in next section). Just enough so that Raspberry Pi runs and I can remote access it. So my first project is pretty simple : go shopping and make a remote access to Raspberry Pi with VNC (Virtual Network Computing). In this post I will write down the steps I’ve done to finish this mini project.
For research purposes I have to install Kali (successor of Backtrack) on Virtual Box. The installation is pretty fast however we have to know what we have to configure the VM settings and what we should choose in the installation step. I just write down these steps for my own documentation, maybe you will find it also helpful.
The most advanced penetration testing distribution, ever.
From the creators of BackTrack comes Kali Linux, the most advanced and versatile penetration testing distribution ever created. We have a whole set of amazing features lined up in our security distribution, geared at streamlining the penetration testing experience.
Lotus Notes and Lotus Domino are the client and server of a collaborative client-server software platform from IBM. The ecosystem provides business collaboration functionality, including email, calendars, to do lists, contacts management, discussion forums, file sharing, instant messaging, blogs, and user directories. Like other business applications, Lotus system conducts a database system behind to manage all data objects for sharing data between internal applications. To make the system itself more friendly to 3rd applications, Lotus also provides a driver – Lotus NotesSQL – so that 3rd applications can query data from Domino server. With Lotus NotesSQL, users and application developers can integrate Domino data with their applications through ODBC. IT professionals can enable their existing ODBC-enabled applications to access data stored in a Domino database. It allows ODBC-enabled data reporting tools, database tools, and application development tools to read, report, and update information that is stored in Domino databases (NSF files).
Android emulator is very famous for its performance. It’s very, very, very notoriously… slow. If you debug your app with Android emulator, it get more extremely slower. This performance problem stems from the fact that Android OS is written for ARM processor (not for Intel/AMD processor or let’s say not for computer processor). Therefore when we get our apps run on Android emulator (which is running on Intel/AMD processor), every assembly code row has to be emulated. A run-time binary translation will happen to translate every assembly code of development machine to device machine. And that point slows down everything.
