Back when game consoles and what were called “home computers” had composite video output using RCA jacks like the one below…
…TVs had either coax cable input…
…or, if your TV was really old, antenna input:
In that era, you needed an RF modulator to convert your console’s or computer’s output into a signal your TV could use:
These days, there isn’t as much need for RF modulator boxes, as consoles and computers have VGA and HDMI outputs, and TVs have corresponding input jacks. However, there are still a number of monitors and other devices that don’t have HDMI inputs, which means that there’s a niche market for HD RF modulators. You can plug an HDMI cable into its input, and its output comes in old-fashioned-TV-friendly coax. If you need to play PS4 or Xbox games on your grandparents’ TV, you might want one of these:
Microsoft’s recent announcement that they’re open-sourcing .NET, making Visual Studio free to small developers, and supporting development for Linux, Android, and iOS is a surprising development from one point of view, but if you were noodling with computers 30 years ago, you may think of it as a return to their oldest ways.
Those of you who grew up in the 1980s and took up programming then will remember the Microsoft logo above. You might not remember the logo they used from 1980 through 1981, making it the shortest-lived logo in their history:
Back then, a computer that you could buy from a retail store and could fit on a desktop was called a “home computer”, and more often than not, it had some version of BASIC(back when it was an acronym for Beginners All-purpose Symbolic Instruction Code), particularly Microsoft BASIC. It was either already in the machine’s ROM, or you’d load it from a plug-in ROM cartridge, cassette tape, or one of those newfangled floppy diskettes. During the “pointy logo era”, BASIC interpreters were Microsoft’s bread and butter, and if you used a version of BASIC that had the LEFT$(), MID$(), and RIGHT$() functions, you were most likely using a version of BASIC with a Microsoft license.
Some of my earliest programming experiences were on a friend’s TRS-80 Model I, which boasted a whopping 16K of RAM and Level II BASIC…
…or its bigger, beefier, disk drive-equipped successor, the Model III, which another friend had:
I would’ve loved to have a portable Model 100 back then:
…because it would’ve let me program anywhere. By this time, a Microsoft copyright notice appeared when you started up BASIC:
Computers were still largely monochrome-displaying creatures back then, so when Radio Shack released a computer that could display color, it was a big enough differentiator for them to name it the Color Computer, even though it could display a maximum of 4 colors onscreen at any given time:
It also had a version of Microsoft BASIC:
If you had an Atari 400 or 800 computer and wanted to program, you’d load up Microsoft BASIC by diskette, or if you didn’t have a disk drive, you’d use a ROM cartridge…
…pull out the manual…
…and start coding:
Terrible as the TI 99/4 was, it did have a decent enough implementation of Microsoft BASIC for me to get started with programming simple adventure games:
At my high school in the early ’80s, we had Commodore PET computers…
…and a good number of us at home had Vic-20s and Commodore 64s…
Commodore machines ran some variation of Microsoft BASIC. Bill Gates offered to license it to Commodore for $3 per unit, but founder Jack Tramiel said “I’m already married” in response. He then managed to negotiate a “pay once, no royalties” deal where they got a perpetual license for $25,000. I have a theory that experiences like this and the copying of his Altair BASIC tape led Gates to become a ruthless businessman in the late ’80s and ’90s.
Here’s a video of the Computer History Museum’s 25th anniversary party for Commodore, where Jack Tramiel tells the story of how he negotiated the deal with Gates:
We think of Apple and Microsoft as rivals, but it wasn’t always that way. Once upon a time, in the days of the
Apple ][, they were hardware/software buddies…
You could program an Apple ][ using the original BASIC that Woz implemented, but if you wanted real programming power, you used Applesoft BASIC, a variant of Microsoft BASIC. The first version was something you loaded via cassette tape:
Applesoft II came out afterwards, and it was 16K in size, which was a lot at the time. Most home computers were based on either the Z-80 processor (the TRS-80s were) or the 6502 (as Apple’s, Atari’s, and Commodore’s were), both of which had a 16-bit address bus. That meant that they could address a maximum of 64K memory locations.
A maxed-out Apple ][‘s memory was arranged this way:
It turned out that through some bank-switching magic, you could boost an Apple ][ to 64K of RAM. You could buy a 16K RAM card that would plug into one of the Apple ][‘s many expansion slots, where it would replace the upper 16K taken up by ROM. You often loaded Applesoft BASIC, Apple Pascal, or some other programming language into it, which is why this 16K card was often called a “language card”. A number of third-party vendors sold such language cards, including Microsoft:
Microsoft even sold a card that put a Z-80-based computer into your Apple ][, which let it run CP/M:
Later, when the original Macintosh came out…
…Microsoft came out with a BASIC interpreter for it…
…and Bill Gates made an appearance at an Apple event where he said that he expected that the Mac would account for half of Microsoft’s revenues in 1984:
When IBM approached Microsoft for software for their new Personal Computer, they got more than just DOS (which Microsoft put together in a hurry by buying 86-DOS from Seattle Computer Products), they also got BASIC:
It was a time when so many different computing platforms were available, each with its own operating system and features. It might have been more difficult to program them, but I found that I could leap from computer to computer with ease, because Microsoft BASIC connected them all. I knew that I could take the code from books like these…
…and make it work on an Apple, Atari, Commodore, IBM PC, Texas Instruments, and TRS-80 with only a few tweaks for each machine.
I’d like to see if Microsoft can repeat this with their new open-approach, open-sourced .NET.
In a CIO article, Tom Kaneshige opens his article about the dislike of BYOD with a couple of examples where employees were “burned by BYOD”:
At a New York banking firm, a couple of executives lost their jobs because they didn’t report lost phones within 24 hours, in violation of a draconian BYOD policy. At a California law firm, the CIO knew every time one of its lawyers slipped away to play golf, exposed by watchful BYOD management software.
Employee issues with BYOD, as Kaneshige points out, isn’t so much about technology as it is about trust — or the lack thereof. People hate BYOD when it encroaches on their privacy, particularly with:
Bad BYOD experiences or outright bans on the work-related use of personal mobile devices often lead to “Shadow IT” or “Shadow BYOD”, a term used to describe when employees use their own devices and applications for work and to access corporate resources without IT’s knowledge or approval. A recent survey by custom business application company TrackVia features these statistics on the mobile work habits of millennials, who are expect to make the majority of the workforce in a few short years:
You can see TrackVia’s complete survey results on their site, where you’ll find the infographic shown below:
“Like many other aspects of IT, BYOD operates across a spectrum from ‘definitely not’ to ‘anything goes’,” says Rob Bamforth, an analyst at the research firm Quocirca. “There will be some for whom BYOD is not the route to go down, principally due to concerns over their ability to implement effective data segmentation and access monitoring.”
Bamforth’s observation is important to keep in mind. A simplistic, restrictive, one-size-fits-all approach to BYOD is more than likely to backfire, as employees find work-arounds to such restrictions and as a result, expose the company to risk as they store company data in unsafe places, using unsafe apps, on unsecured devices. While there are certain lines of work where the security and liability requirements are too strict to allow employees to bring their own devices, most businesses can accommodate a BYOD program that balances security with usability.
SecureData’s head of cloud services, Alan Carter, suggests that setting mobile device policy should first. “Before even thinking about investing in technology, get the policy sorted. Doing it the other way around will result in anything but a perfect rollout.” We agree: an user base who’ve been taught about secure mobile use and who are working under a policy that treats them as intelligent people — and hey, if they’re not, why’d you hire them? — is as important a part of mobile security as any mobile device management solution.

We posted this graph back in July, but it’s worth repeating from time to time: according to tech consultant Chetan Sharma’s US Mobile Market Q1 2014 report, where he pointed out that as of late last year, more than half of the “Big Four” mobile carriers’ ARPU (average revenue per user) comes from data:

As mobile devices become more powerful and take on new forms (first phones, then tablets, now watches and “smart bands”), and as they find their way into more aspects of our work and home lives, their usage — and in turn, mobile data usage and spending — will continue to increase. If you’re in the business of managing mobile expenses like we are, knowing what drives the carriers’ behaviors and offerings is key to finding efficiencies and savings opportunities.
Forbes recently posted an article looking at AT&T and Verizon’s current “more data for less money” offers, where they looked at both telcos’ offerings and compiled them into a single table, which we’ve adapted below:
| AT&T | Verizon | |||
|---|---|---|---|---|
| Monthly fee | Old | New | Old | New |
| $40 | 2GB | 3GB | 1GB | 1GB |
| $70 | 4GB | 6GB | 4GB | 4GB |
| $80 | 6GB | 6GB * | 6GB | 10GB |
| $100 | n/a | n/a | 10GB | 15GB |
| $130 | 15GB | 30GB | 16GB | 30GB |
| $150 | 20GB | 20GB | 40GB | |
* AT&T has a 6GB plan at this price, but it may be discontinued.

Some notable bits of info from the article:
Ars Technica’s Lee Hutchinson was a happy and loyal customer of his carrier until he tried to unlock his device so he could use a local prepaid SIM card while visiting Germany for a week. That’s when it all went downhill, and he shares his story in this article.
The Kansas City Star reports that newly-minted Sprint CEO Marcelo Claure will present his first quarterly report today, the 2Q 2014 report, after the markets close. His first three months — he took over from former CEO Dan Hesse in August after their failed attempt to buy T-Mobile — have seen the carrier change strategies, lay off employees, and cut prices.
Bidness Etc. aren’t very optimistic about the report: while Sprint will likely show an increase in the metrics for current subscribers, there probably won’t be an increase in the number of subscribers, and between price cuts and the cost of network upgrades, ARPU (average revenue per user) is likely to take a hit.
And finally, because a lot of people can’t get enough of him, here’s Sci-Tech Today’s profile of T-Mobile CEO John Legere. He’s loud, he’s audacious, and in a mere two years changed both the company and its public perception dramatically, as well as the way the other carriers have had to do business in response.
