Word Generation from Custom Alphabet – Base 26 Operations

Recently I've developed a brute force password cracker tool (can be found in post BruteForcer). I think it deserves to mention some design characteristics of the application. I'll mention Alphabet Generation in other words base 26 operations that is used and needed for many programmers. Alphabet to Generate Our generator should output strings based on the … Continue reading Word Generation from Custom Alphabet – Base 26 Operations →

BruteForcer – Simple Yet Powerful Brute Force Password Cracker

I'm very forgetful these days. Even though I could not remember what I ate yesterday or what I wore, I have password protected everything. As a result, most of the times I have ended up with a locked zip, tar.gz or other file. Yesterday I had same experience and I decided to write a brute force … Continue reading BruteForcer – Simple Yet Powerful Brute Force Password Cracker →

Price List Application (Flask, SQLAlchemy, pyQT4)

My elder brother needed an application to manage price lists of his wholesalers and dealers. Products' prices that he is following are subject to change daily because exchange rates may change daily and it may be very hard to find optimal price for a product if it can be obtained from multiple dealers. So I decided to help … Continue reading Price List Application (Flask, SQLAlchemy, pyQT4) →

Physical Host Metrics in Ceilometer – An Openstack Liberty Tale

This post is about the errors while getting physical machine metrics with ceilometer specifically Openstack Liberty. Simply errors can be: - No metrics shown in: ceilometer meter-list specifically metrics listed below: compute.node.cpu.frequency compute.node.cpu.idle.percent compute.node.cpu.idle.time compute.node.cpu.iowait.percent compute.node.cpu.iowait.time compute.node.cpu.kernel.percent compute.node.cpu.kernel.time compute.node.cpu.percent compute.node.cpu.user.time - No samples in: ceilometer sample-list --meter compute.node.cpu.* where * is the metrics mentioned above. - … Continue reading Physical Host Metrics in Ceilometer – An Openstack Liberty Tale →

3D Rotations about Arbitrary Axis – Euler–Rodrigues and Matrix Methods

Code is written in python, uses pyglet to draw lines and vertices. All vertex calculations is done without using 3D methods of any library. Euler-Roudrigues rotation and rotation about x, y, and z axis are given separately. Rotation method can be selected from code. Left, right, up, and down arrow keys moves the cube. x, … Continue reading 3D Rotations about Arbitrary Axis – Euler–Rodrigues and Matrix Methods →

Soket Programlama – 2

Basit bir Sunucu Yapalım Bu yazımızda basit bir sunucu yazılımı yapacağız. Bunu temel bazı kavramları yeri geldikçe açıklayarak yapalım. Beklentilerinizin aksine malesef bu sunucu multi-threaded değil single threaded olacaktır. Bu yöntemin seçilmesinin sebebi, asıl amaç olan istemci-sunucu kavramına odaklanılması içindir. Multi-threading kavramını başka bir yazımız için planlayıp konumuza dönelim. Soket (socket) nedir? Soket aslında iki … Continue reading Soket Programlama – 2 →
