I will be quoting quite heavily from the seminal Xlib Programming Manual (3rd Ed, 1994) by Adrian Nye and published by O’Reilly. In this series of posts, I hope to demystify how window managers work, and how you might go about writing one yourself. Hence, almost 30 years since the first X window manager, we still argue over the merits of different window managers, and new window managers continue to reinvent how we interact with our digital world. It is not an exaggeration to say that they define to a large degree our day-to-day user experience, as they are responsible for deciding how individual windows look, move around, react to input, and organize themselves. ![]() ![]() Window managers are one of the core components of the modern Linux/BSD desktop.

![]() You can record from the mic and line-in inputs on a standard sound card, and supports multiple recording channels on high-end, multi-channel sound hardware. Check yours first, but be sure to notice the version number available–the Audacity project also makes beta releases available on its Web site that have new and improved features, and tends to take longer than most projects before declaring a beta release “stable.” So you might find the current beta version direct from the Audacity project stable for your own use and capable of some features not provided in the older release.Īudacity works with Linux’s sound subsystem on almost all sound cards, and is suitable for use with GNOME, KDE, or any other desktop environment. Audacity includes a selection of effects plugins, and can also use industry-standard plugins often made for commercial audio editors.Īudacity is popular enough that most mainstream Linux distributions include it among the standard packages provided by their package management systems. ![]() With Audacity, you can record audio from microphones or other playback devices, mix, edit, and adjust the recordings, edit existing sound files, and output the results to a wide variety of sound file formats. Audacity is a free, open source sound recorder and editor that runs on Linux. ![]() The overall time needed to complete the process depends on your settings, so it could take anywhere from 1 minute to a few hours. Once the recovery process begins, files are organized by type in tabs, thus letting you browse them easily, with a preview window making sure that you’re trying to restore the right file. Thorough scan modes that don't require many resources It’s obvious that the second is the one more advanced, also asking you to choose the file formats you wish to look for. ![]() There are two recovery modes at your disposal, so you can “Dig Deep” and scan file system for deleted files or “Dig Deeper” and scan the disk surface for traces of files. Recover all kinds of data from your PCĭiskDigger works with FAT, NTFS and exFAT partitions and comes with support for a wide array of file formats, such as photos and images, documents, audios and videos, archives, virtual CD images, DLLs and executable files. Still, the whole recovery process has been designed as a wizard, which means users need to follow a few steps and configure the task as they advance towards the end of the process. Easy-to-use recovery toolĪnd as far as we’re concerned, the amount of information provided to the user at any given moment indeed makes the app easy to use, but a dedicated help section with a comprehensive manual would help a lot. In plain English, it claims it comprises not only a very effective file recovery engine, but also an easy to use interface and plenty of settings to play with. File recovery solutions are everywhere you look these days, but DiskDigger promises to offer you exactly the things you need when trying to get back accidentally-removed data. ![]() Why the installation of NX server could fail with error 'Cannot add user: nx' ?

The EA Desktop app should not be seen as a game by GeForce Experience or any other recording software, and the actual game you are playing should be recorded. What happens when the bug occurs? GeForce Experience starts recording the EA Desktop app, and does NOT record the game you are launching. Steps: How can we find the bug ourselves? On a system with an Nvidia GeForce GPU, install GeForce Experience, turn on Instant Replay, and launch an Origin/EA-App-linked game from Steam (for me it happens with Battlefield 4). How often does the bug occur? Every time (100%) The default screenshot, recording and instant replay app of all Nvidia GeForce graphic cards gets broken by your new EA app. Summarize your bug Your new EA app is seen as a game by GeForce Experience, Nvidia's tool for taking screenshots and recording videos (and possibly other recording software) and thus GeForce Experience records the EA app instead of the game you are launching. When did this happen? (dd.mm.yy hh:mm) 06:40 Which client functionality are you experiencing this bug with? Launch Game ![]() Error Report ID (learn how to create an Error Report ID in the sticky post) 8f1f483f-da52-4322-84fb-c85cae72a15d ![]() VCC or VDD: This is the power supply pin and is usually connected to a 5V power source. However, most 433MHz transmitters have at least three pins: The pinout of a 433MHz transmitter may vary depending on the specific model or manufacturer. The transmitter consists of a circuit board with a transmitter chip, antenna, and other components to modulate and amplify the signal. It is commonly used in wireless remote control systems and wireless security systems to transmit data over short distances. ![]() To build a basic 433MHz transmitter and receiver system, you will need the following components:Ī 433MHz transmitter is a device use in radio waves to send signals over a frequency of 433 Mhz. The range of the wireless communication system depends on factors such as the transmit power, antenna gain, and the presence of obstacles or interference. The receiver picks up the transmitted signal with an antenna, filters out unwanted signals, and demodulates the signal to recover the data. The transmitter modulates a 433MHz carrier wave with the data signal using an ASK modulator, and transmits the modulated signal through an antenna. A 433MHz transmitter and receiver pair uses Amplitude Shift Keying (ASK) modulation to transmit and receive data wirelessly. ![]() Plus the program seems to have solved the unstability issues that affected earlier versions, so there's really no reason why you shouldn't give it a try! Nitro PDF Reader features a nicely designed interface that makes the program a pleasure to use. All you need to do is choose the Print option and select the Nitro PDF printer. Another great feature in Nitro PDF Reader is a virtual printer, with which you can convert any document to PDF – as long as the application you use to open it has printing capabilities. ![]() How to Download Videos from Facebook on a Samsung Device Method 1: Using the My Files App
![]() ![]() Then use Command V to paste the password into the appropriate field of the website, app, etc. In order to use a stored password, simply select the entry you need and press Command C to copy your password. Repeat these steps for all of the credentials you have and you will have unique, strong passwords for all of your accounts! Not necessarily as strong as Diceware passwords, but they're the next best thing. Once we have the disk image, we will mount it and drag KeePassX into our Applications folder. Our first step is to download KeePassX from their website. Previously: How to Create an Encrypted Disk Image Step 1: Get KeePassX KeePassX uses either 256-bit AES or Twofish to encrypt the password vault, and has had only a couple of CVEs (Common Vulnerabilities and Exposures) in its lifetime. I prefer KeePassX because it's open source, very secure, works on almost everything, and allows me control over my key database and key file. There are many password managers on the market, and some of the heavy hitters for macOS are LastPass, 1Password, and KeePassX. So instead of rolling up all of our passwords with Diceware, we'll let our machine do the work for us-both in guarding the passwords and generating them. We're also human, so we have a hard time creating random difficult-to-brute-force passwords. Just like most other people, we hackers have a lot of credentials to manage. Now that we've learned about keeping all our data safe with encryption, it's time to continue progressing through getting your Mac set up for hacking. ![]() You will receive a notification on your second device.A notification is sent to the Microsoft Authenticator app on your second device.A 6 digit code will be shown and your account is added.(Note: For iPhone users, you may need to change the app permission to scan the QR code: Settings > Authenticator > Camera) If you cannot use your phone camera, click " Can't scan image?" to enter the 9 digit code and the URL instead.
