The Best Alarm Clock Apps for Android

by Cameron Summerson

At some point during the day (or even night), most of us need an alarm for one reason or another: to wake up for work, to leave for an appointment, or some other thing. Whatever the reason, the smartphone has almost completely killed the alarm clock market at this point—if you’re going to wake up by your phone, then you might as well be doing it right, right?

So you got a Raspberry Pi for Christmas! Now what?

by Alex Bate

Note: The elves at Pi Towers are all taking next week off to spend some time with their families, and this blog will be quiet for the week. We’ll be back at the start of January. Happy holidays!

Happy 25th of December, everybody!

If you’re one of the many who woke up this morning to find some Raspberry Pi goodies under your tree, congratulations.

Christmas

Now you’ve unpacked the Pi, confirmed it to indeed be roughly the size of a credit card, and confused a less tech-savvy loved one by telling them “This is a computer!”, you may be wondering to do with it next…and that’s where we come in.

The Raspberry Pi can be used to create no end of wonderful things, including robots, musical instruments, virtual pets, stop motion cameras, and much more.

It will also help you to learn programming, allow you to play games, offer the chance to explore space, and automate your home.

Not quite like this…

So many awesome things.

But how do you do any of them!? Well…

1. OS me no questions and I’ll tell you no lies.

Awful pun. I’m sorry.

You’ll need to make sure you have the latest Raspbian operating system (OS) on your Pi. You may have been given an SD with Rasbian pre-installed but if not, head to our downloads page to get it.

2. Start me up

ALL THE POWER!

You’ll need to plug your Pi into a monitor (your TV will do), keyboard and mouse in order to get started. You’ll also need a good-quality power supply providing at least 2A.

We’ve some great instructions within our help pages to get you up and running. And if you’re still stuck, our forum has loads of information and is full of helpful people. Feel free to join and ask a question, and search previous topics for advice.

3. So how do I build a robot then?!

With tinsel and tape and bows and…

Excellent question. But if you’ve never tried to code before, you may want to start with something a little smaller…like Scratch or Sonic Pi, or a physical build such as the Parent Detector or a Burping Jelly Baby.

You may also want to check out some great project books such as Carrie Anne’s Adventures in Raspberry Pi or any of The MagPi Magazine Essentials Guides and Project Books.

You’ll find a lot more suggestions in our Christmas Shopping List.

4. More, more, more!

You’ll find more projects on our resources pages, along with some brilliant inspirational builds on our YouTube channel and blog. Or simply search for Raspberry Pi online. We’ve an amazing community of makers who share their code and builds for all to use, and now you’re one of us…WELCOME!

RIP Dr. Henry Heimlich, Inventor of the Heimlich Maneuver

by EditorDavid
tomhath quotes the BBC: Dr Heimlich died at the age of 96. He invented the lifesaving technique, which uses abdominal thrusts to clear a person's airway, in 1974. In May he used the technique himself to save a woman at his retirement home. He dislodged a piece of meat with a bone in it from the airway of an 87-year-old woman, telling the BBC: "I didn't know I really could do it until the other day."

Uranium-Filled 'Lost Nuke' Missing Since 1950 May Have Been Found

by EditorDavid
Although the U.S. government "does not believe the bomb contains active nuclear material," schwit1 shares this report from the BBC: A commercial diver may have discovered a lost decommissioned U.S. nuclear bomb off the coast of Canada. Sean Smyrichinsky was diving for sea cucumbers near British Columbia when he discovered a large metal device that looked a bit like a flying saucer. The Canadian Department of National Defence believes it could be a "lost nuke" from a US B-36 bomber that crashed in the area in 1950.... The plane was on a secret mission to simulate a nuclear strike and had a real Mark IV nuclear bomb on board to see if it could carry the payload required... The American military says the bomb was filled with lead, uranium and TNT but no plutonium, so it wasn't capable of a nuclear explosion... Several hours into its flight, its engines caught fire and the crew had to parachute to safety... The crew put the plane on autopilot and set it to crash in the middle of the ocean, but three years later, its wreckage was found hundreds of kilometers inland. The crew says they dumped their bomb-like cargo into the ocean first to avoid a detonation on land.

Could the Second Amendment Soon Be Law in Mexico?

by CTD Blogger
On October 6, 2016, Mexican Senator Jorge Luis Preciado of the Partido Acción Nacional (PAN) published a policy recommendation in the Senate Gazette to amend Article 10 of the Mexican Constitution to emulate the Second Amendment of the U.S. Constitution, allowing Mexico citizens to carry handguns for personal protection in their homes, vehicles and businesses.

US Scientists Successfully 'Switch Off' Cancer Cells

by Soulskill
iONiUM sends news that Mayo Clinic cancer researchers have developed a technique to reprogram cancer cells in a lab, essentially "turning off" their excessive cell growth. That code was unraveled by the discovery that adhesion proteins — the glue that keeps cells together — interact with the microprocessor, a key player in the production of molecules called microRNAs (miRNAs). The miRNAs orchestrate whole cellular programs by simultaneously regulating expression of a group of genes (abstract). The investigators found that when normal cells come in contact with each other, a specific subset of miRNAs suppresses genes that promote cell growth. However, when adhesion is disrupted in cancer cells, these miRNAs are misregulated and cells grow out of control. The investigators showed, in laboratory experiments, that restoring the normal miRNA levels in cancer cells can reverse that aberrant cell growth.

Should Microsoft Be Required To Extend Support For Windows XP?

by timothy
An anonymous reader writes "If Windows XP were a photocopier, Microsoft would have a duty to deal with competitors who sought to provide aftermarket support. A new article in the Michigan Law Review argues that Microsoft should be held to the same duty, and should be legally obligated to help competitors who wish to continue to provide security updates for the aging operating system, even if that means allowing them to access and use Windows XP's sourcecode."

There really is a daemon in there

by Justin Sherrill

John Marino updated daemon(8) on DragonFly.  For some reason, I didn’t know it was a standalone program.  I knew about the idea of daemons as helpers based inside the computer, which is why so many server programs end with a ‘d’ – sshd, ftpd, and so on.  Inexplicably, I never actually saw the program itself.

The New Google Sheets

by Alex Chitu

There's a new version of Google Sheets. "It's faster, supports larger spreadsheets, has a number of new features, and works offline," informs Google.

Just in case you're wondering how to enable it, you should go to Google Drive's settings page, enable "Try the new Google Sheets" in the Editing tab and click "Save". You'll get the new version of the application only for the files you create from now on. The existing files will still open in the old Google Sheets.


There are some missing features in the new Google Sheets (protected sheets, spell check, publishing) and this shows that this is an early release.

So what's new? You can create and edit spreadsheets offline in Chrome, just like in Docs and Slides. The new Sheets is designed with performance in mind and handles huge spreadsheets: it supports 2 million cells of data and all of the other limitations have been removed. You're no longer limited to 256 columns per sheet. Other improvements: spreadsheets load faster and scrolling is smoother.



There are some new formula editing tools. "In the new Google Sheets, we've made it easier to build complex formulas in your spreadsheets. For example, you'll now see syntax highlighting, which shows you the argument in your function that you are working on, and you'll get more details on how to fix errors in your formula by hovering over them." Google also added 24 new functions, including SUMIFS, COUNTIFS, and AVERAGEIF.


Another new feature is called filter views and it lets you create, save and share filters, so you can get different views of your data without disrupting how others are viewing your spreadsheet.

"In the new Google Sheets, you can apply conditional formatting using a custom formula. This allows you to apply formatting to a cell or range of cells based on the contents of other cells."


You can also add a color to each of your sheet tabs, paste a rotated version of the copied cells from a column to a row or from a row to a column, restrict find and replace to a range of cells and apply custom formatting for currencies, dates, and numbers.

Lazy Reading for 2013/06/02

by Justin Sherrill

Last week was a lot of very brief links.  I’ll go for verbosity this week…

  • Regular expressions and regular grammar.  I hope you like detailed explanations.  I’ve said it before: you should understand regular expressions.  The difference between knowing and not knowing is sometimes the difference between knowing how to finish a project, and being hopelessly swamped.  (via)
  • A plea for less (XML) configuration files.  From the same place.  I don’t advocate rejecting XML files out of hand like some people, but I think you need to have a certain existing level of complexity already in your program before you use XML.  For example, so complex that nobody will notice some XML sprinkled in there too.
  • Where Looks Don’t Matter and Only the Best Writers Get Laid, a talk about the Internet from roughly the late 90s to the 2000s.  Some parts of this get farther into political notes than I usually care to read, but I like the point made with “Many women and men alike are using, not building, the web.”  I am frustrated by how the Internet is effectively one-way transmission for so many, like TV.  (via I forget, sorry)
  • Bringing Unix commands to a Windows world.  It’s about Cygwin.  I’ve installed Cygwin a number of times, but it’s such a strange hybrid I eventually stop after using it for whatever specific reason caused the first install.  These days, it’s almost easier to set up a virtual machine on a Windows system and just switch over as needed.
  • The Weird Stuff Warehouse.  How much does this look like your basement?  I like looking in stores like there cause there’s always some hardware item that seems to be worth resurrecting.  (via)
  • Open Source Game Clones.  I feel iffy about these things.  This tends to be viewed as “I want a free game”, not “I want the right to modify a game”.  Also, you could argue it takes revenue away from the original artists who work on a product when it copies the original game methodology, reducing the incentive to produce.  That could be debated, but I am certain of this: I wish people tried original rather than rehashed ideas in open source, because it has a much lower threshold for success.   You don’t need a studio to tell you when you can be published…  which is sort of the idea behind “indie gaming“, I suppose.  (first link via)
  • Remember those old not-a-desktop-not-a-laptop computers?  They looked like this image I saw recently.  I actually learned to use vi in a mild panic on a Sparcstation Voyager, which would be another device in that land between categories.
  • SSH Tricks, found by accident while I was searching for how to do per-host configs in ssh, so that I only had to type a short name and leave off the long suffix (like dragonflybsd.org) when connecting to a server.  Someday I might even get remote port forwarding over ssh correct.
  • USSR’s old domain name attracts criminals.  Somehow I doubt you can identify a criminal site by domain suffix that easily.  (via)

Your unrelated link of the week: Massive Chalice, a Kickstarter for a new strategy and tactics game.  It’s by Double Fine, who has made some fantastic stuff, and it has permadeath, turn-based combat, randomly generated maps… it’s a roguelike!  It’s cross-platform, apparently, though I don’t know if it will work on any BSDs.

Space Diving: Iron Man Meets Star Trek Suit In Development

by samzenpus
cylonlover writes "Science fiction may well become reality with the development of a real life Iron Man suit that would allow astronauts or extreme thrill seekers to space dive from up to 62 miles (100 km) above the Earth's surface at the very edge of space, and safely land using thruster boots instead of a parachute. Hi-tech inventors over at Solar System Express (Sol-X) and biotech designers Juxtopia LLC (JLLC) are collaborating on this project with a goal of releasing a production model of such a suit by 2016. The project will use a commercial space suit to which will be added augmented reality (AR) goggles, jet packs, power gloves and movement gyros."
