Lumbar Support Can Make a Huge Difference in Your Office Chair

I also spoke to John Gallucci, a licensed physical therapist and athletic trainer who specializes in treating symptoms from poor office posture, and he confirmed much of what Egbert said. Closed case, right? Well, it’s certainly not just marketing speak so that office chair manufacturers can charge you extra. But there are some important factors to consider.
Not All Lumbar Support Is Equal
Gallucci was quick to point out the benefits of lumbar support, but he also issued some warnings about how to proceed. Turns out, not all lumbar support is equal. “The most important thing to look for in a chair is ergonomic adjustability,” he says, referencing the need for adjustable lumbar support. “A good chair should support your posture for long periods without causing discomfort or fatigue. That means it should allow you to adjust the seat height, seat pan depth, armrests, lumbar support, and backrest tilt.”
Chairs with fixed lumbar support mean it isn’t adjustable to your body. Lumbar support and adjustments come in different forms these days. For example, some chairs have lumbar height adjustment but not depth, also known as “two-way” adjustment. Some use a dial for adjustment, and others use a ratchet or lever system. Other chairs let you adjust the entire backrest to find the right position, and some cheaper chairs resort to just a simple pad that can be manually moved. These can, in theory, all be good solutions, so long as you’re able to find the right position.
“That curve has to be adjustable as to where it is,” Egbert says. “My butt might be lower than your butt, and you want it to match where that curve in your lower back is. You want to be able to slide it up and down.”
A good example of an ergonomic chair with “two-way” lumbar adjustment is the Branch Ergonomic Chair Pro. We’ve tested dozens of chairs, and this excellent lumbar support is one of the reasons WIRED’s office chair reviewer, Julian Chokkattu, found it so comfortable. It also doesn’t cost over a thousand dollars like so many high-end office chairs.
If you aren’t ready to shell out $500 on an ergonomic chair, that doesn’t mean you have to be doomed to lower back pain. Some DIY solutions can even be better than a chair with inadequate lumbar adjustment. We’ve even tested some add-on lumbar cushions that we like, such as this LoveHome model you can find on Amazon.
When it comes down to it, though, lumbar support isn’t the first thing to tackle when setting up your workspace. If you’re sitting at an old desk working from only a laptop, lumbar support is never going to solve your posture issues. Fix that first, with either a laptop stand or a height-adjustable monitor.
After that, yes, lumbar support is a good thing. It needs to be adjustable and well-implemented, but it’s something you’ll want to make sure is available on your next office chair. If you’re sitting for eight hours a day, your back deserves it.

Musk’s SpaceX spends $17 billion to acquire spectrum licenses from EchoStar

Elon Musk’s SpaceX has reached a deal worth about $17 billion with EchoStar for spectrum licenses that it will use to beef up its Starlink satellite network.
The deal for EchoStar’s AWS-4 and H-block spectrum licenses includes up to $8.5 billion in cash and up to $8.5 billion in SpaceX stock. SpaceX will make approximately $2 billion in cash interest payments on EchoStar debt through November 2027.
SpaceX and EchoStar will enter into a long-term commercial agreement which will allow EchoStar’s Boost Mobile subscribers to access SpaceX’s next generation Starlink Direct to Cell service.
Shares of EchoStar surged 19% before the market opened Monday.
Last month AT&T said that it will spend $23 billion to acquire wireless spectrum licenses from EchoStar, a significant expansion of its low- and mid-band coverage networks.
EchoStar said that it anticipates that the AT&T deal and the SpaceX transaction will resolve recent inquiries from the Federal Communications Commission about the rollout of 5G technology in the U.S. The FCC had been calling for hearings on whether Echostar was properly using the spectrum that it is now selling, and its efforts to make 5G more available to communities.
EchoStar said Monday that it will use the proceeds from the sale partly to pay down debt. Current operations of Dish TV, Sling and Hughes will not be impacted, the company said.

The New Bose QC Ultra 2 Are the Best Noise-Canceling Headphones Right Now

When it comes to cutting out annoying outside noise, there is no brand in history that has denatured more decibels than Bose. The pioneers of noise-canceling haven’t been without challengers in recent years, including Sony, Apple, and others, but Bose has maintained the crown for generation after generation. Perhaps no product showcases this iterative talent more than its latest earbuds, the QuietComfort Ultra 2.
There wasn’t anything wrong with the first pair. I liked their ergonomic fit, excellent noise reduction, and bold low end, not to mention their excellent microphones, angled toward your mouth in an homage to Apple’s popular AirPods Pro.
With the new QC Ultra 2, we get wireless charging, more customizable sound, better immersive audio, and improved noise reduction. As far as I’m concerned, if you’re a business traveler or someone who wants a compact pair of headphones that truly removes the sound of the world around you, these are—once again—the best you can buy.

I find it very hard to fault Bose for its rubber-stamped design approach; the previous pair were very comfortable and functioned extremely well. The slight changes that appear on the new model are welcome, and I’m not mad at the lack of physical changes.
You now get wireless charging in the clamshell case and a guard to prevent earwax buildup, and you can toggle the included touch controls in the app, which is very helpful when doing activities where you might brush your ear.
Places I don’t find improvements include the weight (the new buds are about a gram heavier but still perfectly fine in your ears) and battery life (the new buds have the same six hours with ANC on, 24 hours in the case as the old model). Bose has even opted for the same drivers in this new generation of buds, with slight tuning adjustments that I’ll get into in a bit.

If you’re new to the world of wireless earbuds or are coming from a more basic pair, the amount of customization that you can do with Bose’s latest buds can feel daunting. You can choose various “modern traditional” adjustments like EQ and noise canceling/transparency modes, but the buds also allow you to dial in two kinds of immersive 3D upscaling (one for staying in place, one for while you move around), among other wild and fantastical new settings that take advantage of modern processors and machine learning tech.

Dell AI server revenues leap but storage waits on Project Lightning | Computer Weekly

Dell’s quarterly results show a huge growth in server sales, driven by artificial intelligence (AI) projects, but a relative lag in storage. Key reasons behind that might be that Dell’s current storage lags a little behind the curve in AI performance, while its massive parallel network-attached storage (NAS) that aims to plug that gap, Project Lightning, is in gestation.
Dell’s PC division usually massively outsells its datacentre products, but that’s not the case in its latest (second) quarterly results, which show 69% growth in sales of servers and networking equipment year-on-year. That equated to a revenue of $16.8bn for the infrastructure division that put the client services – i.e. personal equipment – into the shade with $12.5bn of sales.
Dell has benefited here from being the first to the AI market, with servers, the latest Nvidia graphics processing unit (GPUs), and switches compatible with high throughput Nvidia Spectrum-X networking and Ultra-Ethernet cards.
“In the last six months we have delivered $10bn worth of servers for AI,” said Jeff Clarke, vice-chairman and chief operating officer for Dell Technologies. “That’s more than was attained in the whole previous year. Demand is strong and sales of the new AI hardware has totalled $20bn for the year.”
Overall, Dell’s Q2 results showed record revenue of $29.8bn, which was up 19% on the previous year. Of the $16.8bn of revenue contributed by the infrastructure group – growth of 44% in a year – servers and network equipment contributed $12.9bn.
Meanwhile, however, storage arrays – flash and disk – saw revenues lower by 3% over the year at $3.9bn in the quarter.
Meanwhile, the client services group’s revenue growth was a mere 1% year-on-year, with enterprise PCs reporting $10.8bn revenue (+2%) and consumer products $1.7bn (-7%).
Storage the poor relation in infrastructure sales
A salient feature of these results is that the demands of AI seem to favour compute hardware more than storage.
That might be confirmed by the latest results from NetApp, which is number one in flash storage arrays, according to IDC. Here, the array maker posted quarterly results of $1.56bn in August, which equated to annual growth of 1%.
Meanwhile, Pure Storage announced revenue of $861m, and that was an increase of 13% on sales in a year – but there’s a catch. That set of figures included its delivery – unprecedented – of SSD DirectFlash Modules (DFM) to hyperscaler Meta.
Pure’s DFMs are a proprietary format in which the vendor has packed a much higher density of storage onto SSD cards. That’s because it offloads a lot of on-board cache to the array and handles data there instead.
HPE’s third quarter results showed revenue growth for servers at $4.9bn, up 16% year-on-year, but doesn’t appear to break out storage revenue.
Towards evolution in storage
Why have we seen a boost in revenue for servers for AI, but not really with storage?
There’s no doubt from a technical point of view that storage is an essential support for compute for AI; it’s possible that enterprises have staged their budget spend and focused first on processing power.
At the same time, it’s true that storage products have lagged behind in terms of performance compared with compute. For example, servers that feed GPUs are able to move data at a rate of 400Gbps or even 800Gbps. Current storage products offer around 100Gbps.
Storage suppliers have, however, centred efforts to develop AI storage around parallel file system storage for AI.
Vast Data led the way here, with massive parallel access to storage, while Hammerspace and Weka also followed.
Dell responded with Project Lightning – which comprises Powerscale, the rebranded Isilon scale-out NAS – but that doesn’t seem to have a release date yet. Meanwhile, NetApp has Ontap Data Platform for AI, while Pure has FlashBlade//Exa.
