One of the things that every student of digital electronics learns, is that every single logic function can be made from a combination of NAND gates. But nobody is foolhardy enough to give it a try, after all that would require a truly huge number of gates!
Someone evidently forgot to tell [Notbookies], for he has made a complete 8-bit ALU using only 4011B quad NAND gates on a set of breadboards, and in doing so has created a minor masterpiece with his wiring. It’s inspired by a series of videos from [Ben Eater] describing the construction of a computer …read more
[Ivan] has been keeping his 3D printers busy with parts he’s experimenting with to build a tracked motion setup for a tank-like vehicle. His design uses several interlocking parts, so if you want to duplicate it, we hope your printer calibration is up to snuff. He’s still printing more parts and promises to release the files once the design proves out.
However, you can see he’s off to a good start. Small pieces fit together and accept a piece of filament as a sort of hinge. Some pins keep the filament from working out. Pads fit into the main parts …read more
“It seems that nearly every job posting for a software developer these days requires someone who can do it all,” complains Slashdot reader datavirtue, noting a main focus on finding someone to do “front end work and back end work and database work and message queue work….”
I have been in a relatively small shop that for years that has always had a few guys focused on the UI. The rest of us might have to do something on the front-end but are mostly engaged in more complex “back-end” development or MQ and database architecture. I have been keeping my eye on the market, and the laser focus on full stack developers is a real turn-off.
When was the last time you had an outage because the UI didn’t work right? I can’t count the number of outages resulting from inexperienced developers introducing a bug in the business logic or middle tier. Am I correct in assuming that the shops that are always looking for full stack developers just aren’t grown up yet?
sjames (Slashdot reader #1,099) responded that “They are a thing, but in order to have comprehensive experience in everything involved, the developer will almost certainly be older than HR departments in ‘the valley’ like to hire.”
And Dave Ostrander argues that “In the last 10 years front end software development has gotten really complex. Gulp, Grunt, Sass, 35+ different mobile device screen sizes and 15 major browsers to code for, has made the front end skillset very valuable.” The original submitter argues that front-end development “is a much simpler domain,” leading to its own discussion.
Share your own thoughts in the comments. Are “full-stack” developers a thing?
LoRa and LPWANs (Low Power Wide Area Networks) are all the range (tee-hee!) in wireless these days. LoRa is a sub 1-GHz wireless technology using sophisticated signal processing and modulation techniques to achieve long-range communications.
With that simplified introduction, [Omkar Joglekar] designed his own LoRa node used for outdoor sensor monitoring based on the HopeRF RFM95 LoRa module. It’s housed in an IP68 weatherproof enclosure and features an antenna that was built from scratch using repurposed copper rods. He wrote up the complete build, materials, and description which makes it possible for others to try their hand at putting together …read more
Terrace House is a tough show to explain. Like The Real World and other reality TV, the show puts a group of largely young and attractive strangers together in a house. But that’s about where the similarities end. On Terrace House, most of the cast members genuinely seem to be rooting for each other. And […]
The nominees for the 2018 Hugo Awards were announced today, representing the best science fiction and fantasy literature published in 2017.
The Hugo Awards are one of speculative fictions most prestigious prizes. Named for Amazing Stories editor Hugo Gernsback and first handed out in 1953, they recognize the best works in science fiction and fantasy literature each year. The awards are overseen by the World Science Fiction Society and are selected by members of the World Science Fiction Convention (known as Worldcon). Another set of prizes, the Retrospective Hugo Awards, recognizes works published prior to the beginning of the Hugos (this year, for works published in 1943).
For off-grid renewable electricity, solar seems to make sense. Just throw some PV panels on the roof and you’re all set to stick it to the man, right? But the dirty little secret of the king of clean energy is that very few places on the planet get the sort of sunshine needed to make residential PV panels worth their installation cost in the short term, and the long-term value proposition isn’t very good either.
The drearier places on the planet might benefit from this high-power thermoelectric generator (TEG) developed and tested by [TegwynTwmffat] for use on a wood burning …read more
The world of Minekos Night Market is one obsessed with cats. Felines roam freely around its cartoony, cutesy island. Mini-games make sport of their adventures, and occasionally theyll trail after you like ducklings behind their mother. On Mount Fugu Island, inhabitants even worship cat deities specifically, the Sun Cat, a portly, upright creature called Abe. Developer Meowza Games has made no secret of its love of one specific animal, but the pleasing aesthetic of its upcoming game only lends to the friendly, approachable atmosphere of it all.
Minekos Night Market, launching this year, follows a girl named Mineko whos recently moved to Mount Fugu Island. She currently runs a market, but its been in a financial pinch as of late….
While a lot more than camera gear goes into making those movies look the way they do, the fact that professional filmmakers are using cameras that many of us keep in our pockets is a pretty encouraging sign when it comes to what we should be able to produce.
I wanted to test out just what you can do to improve your phones photo- and video-taking abilities, so I tried out a few different things: some add-on lenses, a microphone, and a stabilizer. You can see the results in the video above.

At a time when the models of traditional social networks are being questioned, it’s more important than ever to experiment with alternatives. Arbtr is a proposed social network that limits users to sharing a single thing at any given time, encouraging “ruthless self-editing” and avoiding “nasty things” like endless feeds filled with trivial garbage.
The New York International Auto Show opens to the public this weekend, and upon entering the Javits Center attendees will be bombarded with new cars, SUVs, trucks and even a handful of supercars that will most likely be out their price range. Heres our primer for anyone who wants to cut through the noise and see the stuff that really matters.
Most Futurama-ready car: Genesis Essentia
Anyone who grew up on dog-eared copies of Popular Science probably assumed wed be riding around in self-driving cars while viewing the passing scenery through glass or plastic bubble roofs. The self-driving car part is playing out right now, but the glass or plastic bubble part seems to…
MIDI instruments and controllers are fun devices if you want to combine your interest in music and electronics in a single project. Breaking music down into standardized, digital signals can technically turn anything with a button or a sensor into a musical instrument or effect pedal. On the other hand, the receiving end of the MIDI signal is mostly overlooked.
[FuseBerry], a music connoisseur with a background in electronics and computer science, always wanted to build a custom MIDI device, but instead of an instrument, he ended up with a MIDI controlled light show in the shape of an exploded …read more
About a month ago, I saw American Made while on an international flight to Barcelona. It seemed like it would be a big and fun enough film to work on a small, dull screen its based on a real story about a guy who simultaneously worked for the CIA, the DEA, and the foreign drug cartels they were trying to bust and for the most part, it was.
The downside is, thats also what was disappointing about the film. The movie seems to have so much to say about the United States meddling in foreign affairs to continually ludicrously effects. And yet, despite establishing all that went wrong, the film never manages to comment on it, or at least not very much.
That lack of depth makes the fun experience ultimately feel just a bit too empty….
Starting today and continuing on for the next week, Google is bringing Wheres Waldo? to Google Maps. On Android, iOS, and the desktop, youll see Waldo pop up in his signature red and white stripes and give you a friendly wave. From there, just tap or click on him and youll see the option to play a game thats straight out of the classic childrens puzzle books. This is one of Googles annual April Fools Day jokes, but the Maps integration is actually happening.
Aside from Waldo himself, youll also be on the lookout for his friends Wenda, Woof, Wizard Whitebeard, and also the villainous Odlaw. (If youre like me, those faces probably wont be quite as familiar to you when you start playing.)
At some point in the not-so-distant past, April Fools was about pranks and hoaxes, but given that we apparently have enough of those on the web, the day has somehow morphed into a celebration of random jokey things. This year’s Google Maps gag is no exception. Starting today, when you open Google Maps on your […]

Im a big fan of Ian McDonalds science fiction novels. The Dervish House and Luna: New Moon are complicated, intelligent stories about how societies cope with advanced technologies. McDonalds next (and final) novel in the Luna trilogy, Moon Rising, isnt hitting bookstores until 2019, but we will have a new story from him to tide us over while we wait: Time Was.
This book is a novella from Tor.com about Ben and Tom, two engineers who fall in love while working on a secret project for the British government during World War II. When they vanish during an accident, the two men are presumed to have been killed, but theyre still alive, simply cast apart in time. They search for one another across the decades, leaving clues in books as…
There are plenty of us out there who enjoy the look of vintage speakers, but using them today isn’t necessarily practical. However, that’s not to say you can’t add some 1950’s flair to your listening setup. The Lofree Poison aims to combine a vintage aesthetic with 21st-century technology, and it’s on sale for $79.99 in the Boing Boing Store.
Boasting a design reminiscent of 1950’s appliances, the Lofree Poison lets you tap into this feeling of nostalgia while blasting your living space with its powerful 20-watt amplifiers and enhanced bass driver. It features a 2000mAh rechargeable battery that allows for up to six hours of playtime and includes a physical rotating dial and built-in FM radio so that you can search for music the old-fashioned way.
