New Touchscreen Technology Improves Contrast of E Ink Screens - Will Be Especially Good For Colour E Ink Screens

Date Published: Thu, 27 May 2021 10:15:37 +0200

Yesterday E Ink announced the launch of a new touchscreen technology for ereaders and e-notes that improves contrast of E Ink screens by 40% for color Kaleido screens and 30% for black and white Carta screens.

The new touchscreen that E Ink has developed is called On-Cell Touch. They don’t give any technical details about it, but apparently it’s cheaper than traditional capacitive touchscreens and it can be used with both flexible and glass-based E Ink screens.

This will be exciting to see on colour E Ink screens which appeared a bit washed out. Colour certainly makes magazines, graphic stories, etc more viable but has long been needing better contrast and clarity.

Unreal Engine 5 Hits Early Access, Linux Still Supported - Games Resolution Will Be Looking Really Realistic

Date Published: Wed, 26 May 2021 23:18:48 +0200

Epic Games today pushed Unreal Engine 5 out to early access. Like with UE4, Unreal Engine 5 continues offering native Linux support and allowing use of the Vulkan API. Unreal Engine 5 is not yet considered production ready but is available in this early form for anxious developers wishing to begin experimenting with this next-generation game engine.

Just watch the interview video and demo at the linked article below to see how incredibly realistic games will be able to look once this is incorporated into modern games. It takes my breath away.

VW ID.4 EV Survives Baja 1000 Mile Off-Road Race Without Any Repairs

Date Published: Wed, 26 May 2021 11:06:09 +0200

It turns out that the Volkswagen ID.4 is a lot tougher than the average crossover. It didn’t win any Baja races, but it did finish one without any repairs. That’s something most vehicles couldn’t do.

Individual stages ranged from as little as 33 miles to 167 miles. Between stages, they charged the ID.4 with a 50 kW charging station, powered by a biofuel generator. Out of 90 vehicles that entered the race, only 64 vehicles finished the brutal race. The ID.4 was raced mostly in “B” level battery regeneration mode with stock traction control turned on.

Race testing is an important part of new design validation as it helps tweak components to endure conditions that most normal users will never encounter.

Emulate the Sinclair ZX81 (or ZX80 and ZX Spectrum) home computer with Linux, MacOS, Windows or Raspberry Pi

Date Published: Wed, 26 May 2021 10:43:11 +0200

Emulation is the practice of using a program (called an emulator) on a PC to mimic the behaviour of a home computer or a video game console, in order to play (usually retro) games on a computer.

The ZX81 was a hugely successful Z80-based home computer produced by Sinclair Research and manufactured in Scotland. It was launched in 1981 and sold for £49.95 in kit form and £69.95 for an assembled computer.

For many of us our introduction to programming came with one of these home computers which helped launch us in our careers. I tested out the ZEsarUX emulator, and it was easy to get running in a GUI environment. Just note it uses ZX81 key mappings, so you may need to open help to remember for example that " is actually SHIFT-P on today's keyboards.

Gromit-MPX Lets You Draw Anywhere On Linux Desktop Screen

Date Published: Mon, 24 May 2021 13:24:49 +0200

Have you ever wished that you could freeze your Linux desktop screen and draw anything on it? Or, you may want to point out or highlight a part of your app or desktop to someone else while screen recording on Linux?

If so, Gromit-MPX is an easy-to-use on-screen annotation tool that you could use right now.

Under X11, it enables graphical annotations with several pointers at once or a dedicated annotation device setup where you can use a second pair of input devices to annotate while simultaneously continuing to work normally with the first pair.

It was an easy AUR install for me on Manjaro and works well. Gromit-MPX is pressure sensitive, if you are using properly configured XInput-Devices you can draw lines with varying width. It is possible to erase something with the other end of the (Wacom) pen.

Full Electric Vehicle Registrations Overtake Plugin Hybrids In South Africa - 92 BEV's registered mainly to the super rich for whole of 2020

Date Published: Mon, 24 May 2021 12:59:48 +0200

Yes the sad fact is that none of the cheaper EVs are available in South Africa so there is nothing for the mainstream buyer to consider. The chief reason why a cheaper EV model comes onto the market is for a cheaper price advantage. SA has the unique position of actively discouraging EV takeup with a heavy additional tax charged.

"Whilst petrol and diesel vehicles from the EU have a customs duty of 18 percent in South Africa, for electric vehicles the duty is 25 percent in South Africa! Then there is the Ad Valorem Customs Excise Duties and VAT".

But finally the SA government is waking up to the fact that the local assembly market for exports of ICE vehicles is going to be drying up, so now there is movement to comment on a draft paper to change incentives.

Even the imminent launch of the VW ID.4 will be at a disadvantage in this market. Once Hyundai, Kia and some of the Chinese BEV's launch here it will signal the viability of more affordable BEV's in SA.

Lithium-Ion Battery Care Multi-Part Guide - They are used in everything from cell phones to power tools to electric cars

Date Published: Sun, 23 May 2021 11:28:43 +0200

They have well defined characteristics that cause them to wear out, and understanding these characteristics can help you to double the life of your batteries or more. This is especially useful for products that do not have replaceable batteries.

Battery wear is loss of capacity and/or increased internal resistance. The latter is not a well known concept, but over time the battery is able to put out less amperage as the battery ages and eventually the battery is unable to generate power quickly enough to operate the appliance at all even though the battery is not empty.

Lithium batteries age from the following factors:

  • Time
  • Cycles
  • Storage/operating temperature
  • Charge and discharge characteristics
  • Depth of charge and discharge
  • Time spent at near empty/near full

The series below goes into each factor in more detail from charging, storage and use of these batteries.

The 25 best educational podcasts for learning what you missed in school - Podcasts are not only music or tech shows

Date Published: Sat, 22 May 2021 14:02:59 +0200

Most folks love learning, regardless of whether or not school is "their thing." Sometimes it's just a matter of finding the right teacher for your learning style — or maybe even the right medium.

For auditory learners, podcasts can be excellent vehicles for processing knowledge that'd be less digestible in more visual mediums like video or even the written word.

There are some quite interesting podcasts listed in the linked article. Why not fill some routine chore with something really interesting to learn about. I did not realise that Spotify has a whole bunch of audiobooks too... to think I just used it for music.

SnowRunner was released on Seam Games and it's working on my Manjaro Linux desktop

Date Published: Fri, 21 May 2021 19:54:57 +0200

I was enjoying MudRunner a lot - relaxing, no rush, beautiful countryside to drive through, etc. So when SnowRunner was finally released on Steam Games I had to see if it worked on Linux, and yes it did with the Proton GE 6.5 driver along with my steering wheel.

Apart from the new vehicles, maps, and physics this game is a multi-player with a Co-op mode (up to 4 players), so you can tackle challenges together or just do a trail drive together with your friends. Some of the custom mod maps can be the most fun.

About the game: "SnowRunner puts you in the driver’s seat of powerful vehicles as you conquer extreme open environments with the most advanced terrain simulation ever. Drive 40 vehicles from brands such as Ford, Chevrolet, and Freightliner as you leave your mark on an untamed open world. Overcome mud, torrential waters, snow, and frozen lakes while taking on perilous contracts and missions. Expand and customize your fleet with many upgrades and accessories including an exhaust snorkel for heavy waters or chain tires to battle the snow."
