The other day I heard a reference to the “high side vs low side” of a computer system in a podcast, and the speaker didn’t stop to clarify. Worse yet is when you hear “on the low side” or “on the high side.” I came from the private sector into government contracting myself. I wasn’t born knowing this jargon either, so I’ll explain it.
Google is moving its corporate applications to the Internet. A year ago I would have said that’s the dumbest thing I ever heard. Today I’m not so sure.
Sticking stuff in the cloud is the popular answer to everything these days, and I just see the cloud as the new mainframe. It’s not a solution so much as a different take on the same problem, and while I see a couple of potential disadvantages, believe it or not I see some real advantages to the approach as well.
My Nook Color is my experimental Android rig. Since it’s aging fast, I don’t use it nearly as heavily as my other Android devices, so if I accidentally do something wrong, I can live without it much more easily than I can do without a phone or my nicer tablet.
So I tend to try a lot of different things on it, just because I can.
Continuing this discussion of Android, the next question that came up was what the deal is with Android memory usage. I wondered the same thing at first, so that seems like a good topic to explain.
Prior to 2005, operating systems tended to use a set amount of memory, then what was left over was for programs. So a freshly booted system would have 2/3 of its memory left free, if not more. If you read my book and my blog way back at the turn of the century, you might have a lot more.
Fire up an Android, though, and you might only have 1/4 of the memory left, or less. Much of this is by design. Read more
Ars Technica made a bit of a splash this week with this provocative headline. This is real.
The article gives the usual advice, like not opening e-mail from strangers, not clicking attachments from strangers, and not visiting dodgy websites. That’s all good advice, as is staying off torrent and other file sharing sites, but even all that is not enough.
I saw an assertion last week that Yahoo and Gmail accounts are less secure than an account that came straight from your ISP. Perhaps there was a time when this was true, but no longer. Today there are reasons to believe the exact opposite is true.
So, no, you don’t have to apologize for using a Yahoo or a Gmail account.
I’m a security professional by trade, with two certifications. I’m not responsible for defending your computer networks, but I want your networks to be secure. There’s a really simple reason for that. If your computer and your network is secure, then it isn’t attacking mine. Or anyone else’s.
Several fellow subscribers to a train-related interest group that I like got hacked recently, and have been sending out spam messages. They’ve received a lot of advice in the hours since. Some of it has been good, and some not as good. So I tried to think of some things that people could do in about 30 minutes to keep the crooks at bay.
Incidentally, the computer crooks won’t be going away. Computer crime happens because the criminals can make more money doing that than doing something legal. The only way to make it stop is to make it too hard, so that getting a real job becomes more profitable. You won’t solve that problem in 30 minutes, but if we all take that single step down that road, we’ll make the world that much safer. So, with that, let’s roll up our sleeves. Read more
Google Drive, on its surface, looks useful. They give me a few gigs of storage that I can access from any computer with Internet access. I could use it like a virtual USB drive.
Except I won’t. The terms of service are too problematic for me. Read more
Antivirus vendor Kapersky has identified a new trojan horse targetting Macintoshes. It spreads a botnet based somewhere in China via an infected Microsoft Word document, typically sent as an e-mail attachment.
The spin is that if you don’t use Word on your Mac, you’re safe. That’s true–this week. But going forward, it’s going to take more than that. Read more
