NASA Announces Artemis III Crew And Ambitious Goals

When the Artemis lunar program was first conceived, the third mission would have seen astronauts step foot on the Moon for the first time since Apollo 17 in 1972. But as hard as getting into space is, a sojourn to our nearest celestial neighbor is even more mindbogglingly complex, and so earlier this year it was announced that actually landing on the Moon would be pushed out to the fourth mission.

In turn Artemis III would take a page out of the Apollo 9 playbook and test out rendezvous and docking procedures with commercial landers while operating in the relative safety of low Earth orbit. Moving the target date for the landing a few years down the road gave all involved parties a little more breathing room, but it also provided a valuable opportunity to gain insight into the performance of the vehicles and systems ahead of the critical moment. In the original timeline, the first time Orion would attempt to dock with the lander would have been just before descending to the lunar surface — leaving precious little time to troubleshoot should anything go wrong.

Yesterday NASA held a press conference to update the public on their progress towards the planned 2027 launch of Artemis III, which included the long-awaited announcement of the crew that will kick the tires on the next-generation lunar landers being developed by SpaceX and Blue Origin

Revisiting Using AI Coding Assistants: You’re Holding It Wrong Edition

After scathing accusations of skimping on due diligence, as well as other feedback to my article on trying to use an ‘AI coding assistant’ for the first time, the only rational, academic response is to lick one’s wounds following a particularly bruising peer review and try to address the raised issues. Reality after all does not care about one’s feelings, and there may be more to this AI assistant technology that can be coaxed out with a more in-depth look.

To this end I’ll do my best to try and work through each raised point, criticism and accusation, to see what I – and perhaps others – can learn of this endeavor. Said points include the use of the wrong frontend – i.e. Copilot – and the wrong model – being Claude Haiku 4.5 – as well as the egregious flaw on my end of ‘prompting wrong’.

For the sake of due diligence the best frontend and models will be investigated for particular tasks, with finally the verbal minefield of ‘prompt engineering’ examined for industry-standard approaches.

Hunting Submarines Via Gravity Is A Tough Errand

Among so many other technological advances, the Cold War saw the advent of the ballistic missile submarine. The concept was simple—pack enough nuclear warheads to destroy a small civilization into a compact metal tube, and then hide it underwater. The oceans would act as a cloak for your fleet of world-enders, and keep your enemies forever on their toes. A terrifying machine that could both start and end a war with the push of a button.

Most nation states are populated by humans with the will to live. Thus, there has been a great incentive to find ways to keep tabs on these sunken doombringers. Great efforts have gone into improving sonar and magnetic detection methods over the decades, which are the bread and butter of sub hunting to this day. However, military researchers have also explored the prospect of whether submarines could be detected via their effect on the gravitational field alone.

Remember When Flash Drives Were Going To Make Your PC Faster?

The 2000s was a decade of great change in the computer industry. The world had grown accustomed to corruptible floppy disks, blue screens of death, and achingly slow load times. In a few short years, all of that would change, as USB drives, better operating systems, and faster processors brought forth a new age of stability and speed.

Amidst this era of upheaval, Microsoft introduced a new technology. It was intended to increase performance on the cheap to a new generation of machines, but it would turn out to be little more than a gimmick that never really caught on. Let’s explore the easily-forgotten legacy of ReadyBoost.

Magnets Are Bad For Hardware Again

If you were around tech in the bad old days, magnets could be really bad news. They were fine on the fridge, no problem at all. Put one near a floppy disk, or a hard drive, or even a computer monitor, though, and you were in for some pain. You’d lose data, possibly permanently destroy a disk or drive, or you’d get ugly smeary rainbow effects all over your screen.

The solid state revolution has eliminated a lot of these problems. We all use SSDs, flash drives, and LCD monitors now, all of which care a lot less about flirting with magnets. However, the same can’t be said about all our modern hardware, for a magnet could cause your smartphone some major grief indeed.

Between-Device Sharing Still Sucks

Once upon a time, computing was simple. You had files on a floppy disk. If you wanted to take them to a different computer, you ejected the disk from one machine and put it in another. It wasn’t fast, but it was easy and intuitive. Besides, you probably only had one computer of your own, anyway.

Life has since gotten a lot more complex. You’ve got a desktop, a laptop, a work laptop, your personal and business phones, and a smart watch to boot. You live amongst a swirling maelstrom of terabytes of data. Despite all the technical advances that got you here, it’s still a pain to get a file from one device to another, even when they’re sitting on the same desk. Why?!

How Search Engines Enabled Finding Needles In A WWW-Sized Haystack

When the World Wide Web surged into existence during the 1990s, we were introduced to the problem of how to actually find something in this ever-ballooning construction zone that easily outpaced even the fastest post-WW2 urban sprawl. Although domain names provided a way to find servers using DNS rather than having to mash in IP addresses, you still somehow had to know the relevant URL.

A range of solutions were thought up over time, ranging from printed Yellow Pages type guides, to online curated lists of resources, as well as things like web rings where one website would link to a relevant similar website. This was the time when word-of-mouth was also very relevant, with people proudly announcing their own website on Geocities or other hosting service.

Search engines already existed long before the WWW became the hot new thing during the 1990s, but it was the WWW that would really push them to their limits. As anyone who used search engines for the WWW can attest, they had many issues. Often you’d end up using multiple search engines to find something, and despite fierce competition between web search engines to become the starting page for their browser, actually finding things on the WWW remained a tough problem.

Since a web search engine ‘just’ has to index the WWW and match a search query against the results, why was this such a hard problem that persisted until Google apparently cracked the code?
