Raspberry Pi: The smart person’s guide

The Raspberry Pi’s success defied expectations. Conceived as an affordable computer for getting kids to learn how to code, its creators thought they’d sell 1,000. They’ve sold more than eight million. Here’s why.

Executive summary

  • What it is: A credit card-sized computer that costs as little as $5 that spawned a community of millions of home makers and programmers.
  • What it does: A lot. Despite its low-cost, the Pi can be run as no frills PC, a pocketable coding computer, a hub for homemade hardware and more.
  • Why it matters: The Pi is a great machine for stoking interest in programming among schoolchildren worldwide and helping create the next generation of developers.
  • Who it affects: Anyone with the inclination to pick up a Pi and start tinkering.
  • When is this happening: Right now. More than eight million Pi boards have sold since the machine’s launch in 2012 and demand was reinvigorated by the recent release of the Raspberry Pi 3.
  • Where is this happening: All over the world, with the Pi’s official forums supporting a community of more than 150,000 active users.
  • Who is making it happen: A not for profit charity on a mission to get the world interested in how computers work.
  • How to get it: Online from Premier Farnell and RS Components, if you’re based in the UK, or from Allied Electronics or Newark, if you’re in the US.

Upcoming TAPCUG and OMUG Linux SIGs

The next TAPCUG Linux SIG meeting is Sep 15, 2015 (3rd Tuesday) 5:30 PM – 8:30 PM at the SE Tacoma Community Center 1614 99th St E, Tacoma, WA 98445. Traditionally we are on vacation during the summer- June, July, August.

The next OMUG Linux SIG meeting at the Olympia Center is Aug 11, 2015 (2nd Tuesday) 7 PM, see http://olymug.org . To get the most out of these meetings bring your ideas, questions and be an active part of the discussion. New members are always welcome.

We have three major computer systems today: Windows which is based on DOS, Apple’s OS X which was derived from open source FreeBSD . (Windows and Mac are closed proprietary systems). Linux, which is based on the Linux kernel and unlike the first two, is basically free and open source. Companies make money from the packaging and support of Linux.Linux is much more secure because its roots are from Unix,a serious business multiuser system. Linux has extra built in security such as Netfilter and IPTables which makes your system rock solid and secure.

Linux was created by Linus Torvalds in 1991 because he wanted a better desktop operating system. Ironically, it has totally dominated everywhere else from supercomputers, to servers, chromebooks and your smart phone but monopolies have so far mostly kept it off computers you can buy until now. It is now time to switch to Linux including Linux Mint XFCE or a Chromebook.  Linux Mint is the number four operating system in the world! Download and try it for free. Install if you like it. You convert easily and save lots of money! A+ Computers sells Linux computers along with other proprietary computers.

At the TAPCUG General meeting Aug 8, 2015 we will demonstrate Google+ Hangouts on a Samsung ARM Chromebook. At the Sep 15, 2015 TAPCUG Linux SIG we will review all the software that runs on the Raspberry Pi 2 including Berryboot and Noobs. We will review gpt vs mbr partitioning, xda Android replacement, plex, Chromixium, Nvidia Tegra K1 computers, K1 Linux install, Transmission, Openshot, Google Drive, Linux flash drive install, Gnome system monitor, quantum computers, youtube-dl, gsmartcontrol for hard drivesLightbeamGoogle hangout, Google Keep, Kdenlive, recorditnow, Chromecast, Pixel Qi screens, Remastersys and mesh networks, dual booting Linux on a Windows 8 computer, audacity, Mint xfce 4.12 upgrade, smart phone customizing: Convert Android to OnePlus One, TV music streaming, owncloud, youtube-dl, Google+ Hangout On Air,Samsung ARM chromebook hdmi to vga cable, BIOS replacements including UEFI, Coreboot, Seabios, OpenBios, Plop, flashrom.

We also plan to connect other persons computers to the projector so they can demonstrate what they are using.

How To Defragment Your Disc Drives In Windows 8.1

The good old Disk Defragmenter tool that suffered a series of changes in Windows 7 has been changed again in Windows 8.1. It has a new name – Optimize Drives – and some new inner-workings. As a result, defragmenting drives in Windows 8.1 is a little bit different from what it used to be in previous versions of Windows. Read on to learn how to defragment your disc drives in Windows 8.1.

When To Use Optimize Drives?

When defragmenting a disk partition, Windows rearranges the files stored on the disk so that they occupy contiguous storage locations. Doing this increases the access speed to your files by minimizing the time required to read and write files to/from the disk and by maximizing the transfer rate. You might also see improved startup times.

Defragmentation should be done especially when both your operating system and your most commonly used applications are installed on the same drive and the operating system gets slower over time.

Do not defragment SSDs or USB drives. These types of drives have a different way of allocating files and they have a limited number of read/write cycles before they stop working. Hence, defragmenting them will decrease their lifespan. Given the high read and write speeds provided by SSDs, you shouldn’t encounter slowdowns anyway, so there’s no reason to defragment them.

How To Really Speed Up Your Computer – Common Myths & What To Do Instead

You might have noticed that your computer has never been as fast as it was when you first got it. But do you know why our devices slow down over time? Many of us have a number of misconceptions about sluggish PCs, so let’s crack these open and find out how to actually speed things up.

There are myths about slow computers that still get rehashed to this day: keeping too many files slows your machine down; you need to buy as much RAM as possible; viruses are designed to make everything run sluggish. In actuality, these statements aren’t true. Although they do have nuggets of truth contained within, it’s time to separate the wheat from the chaff.

Sticking with Windows XP? Here are your options

If you’re a Windows XP stalwart, you may decide to stick with Windows XP, even after Microsoft officially ends support. Scott Lowe discusses some of your options for making things work with what you have.

If you’re still running Windows XP in your organization, you’re probably painfully aware of the pending end of support for the venerable — but wildly popular — Windows XP operating system. Released in 2001, Windows XP was originally dismissed as a “play toy,” thanks to an interface that people compared to Fisher Price products. But with a couple of rock solid service packs, XP became the real workhorse of the enterprise.

And then along came Vista. There’s probably not much I can say here that hasn’t been said elsewhere. Vista was an unmitigated failure on the part of Microsoft and its overambitious and poorly planned development process.

Next came Windows 7. Much like Windows XP, Windows 7 has been greeted with great acceptance in both the consumer and enterprise spaces. As a result, many organizations made the jump from Windows XP directly to Windows 7. However, plenty of others couldn’t justify the time and expense of shifting to a new operating system when Windows XP was perfectly viable, so a lot of companies decided to wait for Windows 8.

And today, Windows 8 has been largely written off as a debacle, much like Vista. This leaves organizations with an option to move to Windows 7, which remains an excellent operating system, move to Windows 8, which is considered high risk for many, or find ways to stick with Windows XP and continue to make it work while the world awaits the release of Windows 9, which we all hope is a successful undertaking.

Review: Dashlane is a robust password manager with a gorgeous interface

A password manager is a must. Unless you’re using the same password for everything (not recommended) or have a truly phenomenal memory, your productivity can benefit from a place to store all your passwords and easily use them whenever necessary. There are several strong players in this field, such as LastPass and KeePass. Dashlane (free for basic version, $20/year for Premium) aims to take on both.

Dashlane is a robust password manager with additional room for your various IDs, credit cards and other payment methods, receipts, and notes. It comes with an auto-fill feature for online forms to which you can add different addresses, phone numbers, and other personal information you’re tired of typing repeatedly. There are two features that make Dashlane stand out when compared to both LastPass and KeePass: Its beautiful and easy-to-use interface, and its optional cloud syncing.

Buying A New TV Or PC? Avoid Showroom Tricks That Cost You Money

Wondering why your HD TV isn’t producing images as good as in the store, or baffled you’re your expensive new computer isn’t as fast as advertised? The truth is, special techniques and tricks are used to persuade you to part with your money for hardware that you might have avoided under other circumstances.

One of my pet hates is shopping in a consumer electronics store. Over the years I’ve become more and more resistant to their tactics and approaches, thanks mainly, I think, to the realisation that they haven’t been entirely honest with me.

Throw in some experience working at a major electronics retailer in the late 1990s (where I picked up a few tips and tricks concerning customer-facing roles) and it seems apparent that what we experience in these stores is pretty much theatre.
