SLogLib is a flexible logging library written in C++. It comes with three logging devices: console, file, and memory but often there is a need to show log directly on the user interface. I heavily use Qt for all projects requiring user interface, so I wrote a logging device for QWidget. It is available in …
Recently, I worked on a project which made heavy use of C++ threads. To use SLogLib in this project I added multi-threaded support in SLogLib with the help of c++ 11 std::mutex and std::lock_guard. Over the last few months multi-threaded support in SLogLib has been extensively tested and there are no known bugs. All threading …
If you received “Object arrays cannot be loaded when allow_pickle=False” while loading a numpy array using numpy.load() it is because numpy has changed the default loading behaviour since version 1.16.3. If you are using numpy version newer than this, at many places on internet it is advised to simply downgrade the numpy version. This is …
In the previous post, I discussed a solution to Kaggle’s Dogs vs. Cats Challenge using Convolutional Neural Networks. CNN’s takes time to train and I tried a number of different network models and various values for hyperparameters before achieving 94% accuracy. This was very time consuming and it took around two days to determine the …
Dogs vs. cats challenge [1] from Kaggle ended in Jan 2014 but it is still extremely popular for getting started in deep learning. This is because of two main reasons: the data set is small (25,000 images taking up about 600MB), and it is relatively easy to get a good score. There are many many …
Some time back, I developed a data entry application in Qt5. One of the requirements was to let the user select a single string from a predefined list of string. I developed a custom widget called SStringSelector for this purpose. SStringSelector has two views: display and selection. The display view presents the currently selected string …
Qt5 support standard dialogs such as QFileDialog, QFontDialog, and QColorDialog, however, it does not provide a color picker to allow a user to pick a color. Recently, I need a color picker for one of my projects and I implemented a simple color picker widget. SColorPicker is available from Github as a part of QtUtils …
Recently, I had to give away a computer with couple of disks in it. I wanted to securely erase data on these disks as I stored personal sensitive information on them. Using a program such as DBAN was not an option as I was not allowed to remove the operating system from the computer. My …
To see tomato cells under microscope, simply squeeze a bit of tomato juice on a clean glass slide and gently place a cover slip over it. Micrographs Below is the micrograph of the tomato cells: Tomato cells are floating in the juice and hence are not connected to each other. The thick black circles are …
This week, at work I had to implement a search box for a software I am working on. The search box is to filter some data dynamically as user types a query. I wanted to show a clear (cross) icon at the right side of the search box so that user can clear the results instead …
