From this article, the Raspberry Pi 4’s USB-C power port was designed outside of official USB-IF specifications, making it incompatible with many USB-C chargers and/or power supplies. You can read more about from the link above and the information gathered to come to such a conclusion was done by a well known Google engineer, Benson Leung.
The raspberry Pi is a collection of small computer boards put together in a simplistic way to create the foundation of a computer system. The Raspberry Pi (also known as RPi) was released back in Feb of 2012 in the United Kingdom. The original intent of the RPi was to develop a low cost and simplistic computer which students could learn and develop.
The original model became far more popular than anticipated, and started selling outside its target market for uses such as robotics. It does not include peripherals (such as keyboards and mice) or even come inside a case. Literally a bare-bones product.
To give you an idea of the popularity, the RPi products have sold over 19 million units between its release in 2012 to the end of fiscal year 2018. This makes the RPi one of the best-selling computers in the world, although a computer with limited resources. Until now.
This week the Raspberry Pi Foundation has released the Pi 4. This is one hell of a great product. Check out these specifications:
- A 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU (~3× performance)
- 1GB, 2GB, or 4GB of LPDDR4 SDRAM
- Full-throughput Gigabit Ethernet
- Dual-band 802.11ac wireless networking
- Bluetooth 5.0
- Two USB 3.0 and two USB 2.0 ports
- Dual monitor support, at resolutions up to 4K
- VideoCore VI graphics, supporting OpenGL ES 3.x
- 4Kp60 hardware decode of HEVC video
- Complete compatibility with earlier Raspberry Pi products
In addition to the hardware improvements, the Raspberry Pi Foundation says
It’s been a hard day because your USB stick or SD card with important content doesn’t have the file you are looking for. Somehow, maybe your kid, formatted the device and what you are looking for is no longer there.
Wouldn’t it be nice to get some recovery software to find that file?
Better yet, wouldn’t it be nice to have a free download to show you what files can be seen… and then you can decide to buy the software? I mean, your day has already been bad enough, why spend money for a shot in the dark?
EaseUS Data Recovery software is just what you need. Today is a review of this software. Our first and last impression, it’s good stuff!
Here is the “Readers Digest” version of the data recovery software review. Oh, and if youâ€™re a millennial who doesn’t know what “Readers Digest” is, it was a small magazine that would provide short stories and reviews and jokes. Nothing long, everything quick and to the point.
The EaseUS Data Recovery software is free for download with upgrade options.
The fee download gives you the ability to recover up-to one GB of data. The types of situations the free software is best used for is when the file was deleted or the file was formatted off the drive.
Anyone in tech has seen the reports and news about USB sticks with a virus ruined a company network or infect computers. Google built a small and affective feature into their latest Chromebooks.
The USBGuard is a feature which blocks interaction between the mass storage device and the Chrome operating system. The OS will give power to the device, but not let data transmit.
The USBGuard blocks this activity when the Chromebook is in locked mode. When the Chromebook is not in lock mode, the USB will interact as expected as a read/write device.
Account security is one of the most vital pieces of the busy and interconnected world right now and nobody wants strangers accessing their personal information online. You might use a password manager as well as two-factor authentication like we mentioned in a previous post, but now there’s another way to stay protected.
In response to similar approaches from Google and Dropbox, Facebook has added support for safe login security keys. When you log into your account, this device will prove your identity rather than a code which sends to your phone. In addition to the superior security, they’re also potentially faster. With just a tap on the device you can have access to your Facebook account and feel safer in knowing only you can unlock it. It’s a welcome move from the company in an age where cyberattacks and identity theft are on the rise and as a universal rule on the internet, it’s never a bad time to strengthen your defences.
If the “smart TV” craze hasn’t made it to your home entertainment yet, making one on your own is getting easier every year. All you need is a spare HDMI slot and the Intel Compute Stick.
There are two ways to make a USB stick read only. One way is a universal solution and is 100% permanent, the other way is PC specific and a good deterrent. When we say 100% permanent, this means the USB stick is read only (write protected) on all computers, whether it be a Mac, PC, Linux, etc type computer, the USB is read only and the status cannot be changed. The other method flags a USB device to be read only in relationship to the PC it is connected to so that whenever that USB stick is connected to that computer, it makes the USB read only and blocks all write commands to the device.
Most times an IT manager or content owner wants the USB stick to be read only so the files cannot be deleted or formatted off the drive. Another reason for making a USB read only is for the original files to remain the same and blocks the ability for files to be changed or manipulated. Finally, it’s smart to have USBs read only so that virus’ don’t jump onto the drive and possibly spread to other computers.
Let us start with the less permanent way because it’s easier to do and doesn’t require any specific hardware. You will need a Windows7 machine or higher. The Windows7 machine will have DiskPart utility which allows us to perform all sorts of cool things to flash drives, like setting write protection.
- Connect the USB to your Windows computer.
- To begin, go to your Windows Start and in the Search Field type â€œcmdâ€
This will run your Command prompt.
- Next, you will want to get to the C root of the Command prompt and if you are signed in as a user you can simply type cd\ this will get you back to the root of the C drive.
- Type DISKPART
- Type LIST DISK
Now you will need to find the USB stick connected to your PC. Most likely it’s DISK 1
