Tags 2:33 The versatile Nebula Mars II is a fully self-contained 720p projector with great speakers and a 4-hour battery. Anker Got wall? Cool. Let’s turn it into a home theater.Today only, and while supplies last, the Anker-made Nebula Mars II portable projector is on sale for $330 . That’s $30 less than the last time I wrote about it and the lowest price to date. (It normally runs $500.)See it at AmazonThe Mars II (sequel to the popular, but slightly flawed, Mars Portable Cinema) offers full 720p resolution, 10-watt speakers, a 4-hour battery, auto-focus and Android 7.1.That OS allows you to run just about any streaming app (Amazon Video and Netflix come preloaded), and the companion Nebula app turns your phone or tablet into a much-needed remote for those apps. That said, this thing would be downright incredible with a Fire TV or Roku UI.You can plug any source into the projector’s HDMI port, but obviously that source’s power requirements may limit overall portability.In my brief and informal product tests, I was impressed by image brightness and quality and the loudness of the speakers. Auto-focus could be a little slow when moving the projector around. But once it’s parked, it’s all good.Speaking of parking, the main appeal of the Mars II is its portability. It can run pretty much anywhere there’s Wi-Fi for streaming, though if you plug in a movie-filled USB drive, you don’t even need that. Indeed, this would be just about the perfect projector for those AtmosFX Halloween animations.

Parliament FILE PHOTOThe fourth session of the 11th parliament will begin on 8 September next after a 59-day recess in the proceedings of the Jatiya Sangsad, reports UNB. President Abdul Hamid on Wednesday summoned the fourth session of the 11th parliament, said a Parliament Secretariat media release. Before the House goes into the session at 5:00pm on 8 September, the business advisory committee of parliament is likely to sit at a meeting to fix the duration and businesses of the session. On 11 July last, the third session (budget session) of the 11th parliament was prorogued, which passed the national budget for 2019-20 fiscal year, supplementary budget for 2018-19 and 7 bills, including Law and Order Disruption (Speedy Trial) (Amendment) Bill, 2019, during its 21 working days.
The American and British flags were lowered and folded up for the final time at the regional headquarters of the international military, 13 years after the toppling of the Taliban’s radical Islamist regime launched America’s longest war. The timing of the troops’ withdrawal from the base in the strategic province of Helmand was not released for security reasons. However, according to earlier reports, the ‘longest war in American history’ will last at least another decade, as per the conditions of a garrisoning deal for US forces signed by the new Afghanistan government late last month.The deal guarantees that US and NATO troops will not have to withdraw by year’s end, and permits their stay ‘until the end of 2024 and beyond.’ Also Read – Need to understand why law graduate’s natural choice is not legal profession: CJIBut the current wrap-ups hold high symbolic currency. Camp Leatherneck is the largest US base to be handed over to Afghan control as the coalition ends its combat mission at the end of the year, leaving most of the fight against a resilient Taliban insurgency to Afghan army and police. British forces transferred the adjacent Camp Bastion at the same time. Once a teeming compound of some 40,000 personnel, the coalition’s Regional Command (Southwest) combined base on Sunday resembled a dust-swept, well-fortified ghost town.

Offices were bare, and bulletin boards stripped of photo tributes of fallen American troops. The most recent official estimate of combined international troops at the base was 4,500 – and those last few will be gone soon, officials said. After the withdrawal, the Afghan National Army’s 215th Corps will be headquartered at the 6,500-acre base, leaving almost no foreign military presence in Helmand.
Yesterday, the Deliveroo engineering team shared their experience about how they migrated their Tier 1 service from Ruby to Rust without breaking production. Deliveroo is an online food delivery company based in the United Kingdom. Why Deliveroo decided to part ways from Ruby for the Dispatcher service? The Logistics team at Deliveroo uses a service called Dispatcher. This service optimally offers an order to the rider, and it does this with the help of a timeline for each rider. This timeline helps in predicting where riders will be at a certain point of time. Knowing this information allows to efficiently suggest a rider for an order. Building these timelines requires a lot of computation. Though these computations are quick, they are a lot in number. The Dispatcher service was first written in Ruby as it was the company’s preferred language in the beginning. Earlier, it was performing fine because the business was not as big it is now. With time, when Deliveroo started growing, the number of orders increased. This is why the Dispatch service started taking much longer than before. Why they chose Rust as the replacement for Ruby? Instead of writing the whole thing in Rust, the team decided to identify the bottlenecks that were slowing down the Dispatcher service and rewrite them in a different programming language (Rust). They concluded that it would be easier if they built some sort of native extension written in Rust and make it work with the current code written in Ruby. The team chose Rust because it provides high performance than C and is memory safe. Rust also allowed them to build dynamic libraries, which can be later loaded into Ruby. Additionally, some of their team members also had experience with Rust and one part of the Dispatcher was already in Rust. How they migrated from Ruby to Rust? There are two options using which you can call Rust from Ruby. One, by writing a dynamic library in Rust with extern “C” interface and calling it using FFI. Second, writing a dynamic library, but using the Ruby API to register methods, so that you can call them from Ruby directly, just like any other Ruby code. The Deliveroo team chose the second approach of using Ruby API, as there are many libraries available to make it easier for them, for instance, ruru, rutie, and Helix. The team decided to use Rutie, which is a recent fork of Ruru and is under active development. The team planned to gradually replace all parts of the Ruby Dispatcher with Rust. They began the migration by replacing with Rust classes which did not have any dependencies on other parts of the Dispatcher and adding feature flags. As the API of both Ruby and Rust classes implementation were quite similar, they were able to use the same tests. With the help of Rust, the overall dispatch time was reduced significantly. For instance, in one of their larger zones, it dropped from ~4 sec to 0.8 sec. Out of these 0.8 seconds, the Rust part only consumed 0.2 seconds. Read the post shared by Andrii Dmytrenko, a Software Engineer at Deliveroo, for more details.
