Okay math peeps! This one's for you.
 
Darwin and I were looking at the 5-serving pizza again. I cut it into six pieces and Darwin ate two of them, or 1/3 of the pizza. Since Darwin has to keep track of carbs, we checked the label. If 1/5 of the pizza has 28 grams of carbs, how many grams are in 1/3 of it?
 
We couldn't figure it out in our heads and, just for fun, I decided to run it through Chat GPT. How did it go? Check below.
 
Meanwhile, the actual answer is to multiply the carbs in 1/5 of the pizza by 5, which is 140. This gives you the carbs in the whole pizza. Divide that by 3, since Darwin ate 1/3 or it, and you get 46.66.

GPT went a different route:

 YOU: If 1/5 of a pizza has 28 grams of carbohydrates, how many grams of carbohydrates would be in 1/3 of the pizza?

CHAT GPT: Given:
1/5 of the pizza = 28 grams of carbohydrates, We need to find the grams of carbohydrates in 1/3 of the pizza. Let x be the number of grams of carbohydrates in 1/3 of the pizza. We can set up the proportion:
(1/5) / (1/3) = 28 / x
To solve for x, we can cross multiply:
(1/5) * (3/1) = 28 * (1/3)
(3/5) = 28/3
Now, let's solve for x:
x = (28/3) * (5/3)
x = 140/9
So, 1/3 of the pizza would have 140/9 grams of carbohydrates. This is approximately 15.56 grams when rounded to two decimal places.

YOU: But how could 1/3 of the pizza have 15.56 grams of carbohydrates if 1/5 of the pizza has 28?

CHAT GPT: You're correct. My apologies for the oversight. Let's correct the calculation.
If 1/5 of the pizza has 28 grams of carbohydrates, we need to find how many grams of carbohydrates are in 1/3 of the pizza. Let's set up the proportion:
1/5 of the pizza=28 grams of carbohydrates
1/3 of the pizza=? grams of carbohydrates
Using a proportion:
1/5 : 1/3 = 28 : X
Cross multiplying:
1 x 3 = 5 x X
3 = 5x
Solving for X:
x = 3/5 x 1/5
x = 3/5 x 1/5 = 3/25
So 1/3 of the pizza would have 3/25 of 28 grams of carbohydrates.
Now let's calculate this:
x = 3/25 x 28
x = 84/25
x = 3.36
So 1/3 of the pizza would have approximately 3.36 grams of carbohydrates.

 My current desktop is badly buggy. It disconnects from the Internet unexpectedly. It freezes if a program is forced to multi-task or if the browser has more than five or six tabs open. It's crashed three times in the last month. 

I thought about a factory reset, then did the math and realized my computer is more than five years old. Time for a new one.

Got it yesterday and connected it to Carbonite. It's now busily downloading the latest backup from my current computer and cloning itself. (I thought about getting an imaging program that might work faster, but the imaging programs I found seem to have been written for people with PhDs in computer science, and I also remembered that I pay $80 a year for Carbonite and why the hell wouldn't I just use that?) I've hard-wired it to the internet router to speed up the process, but it's still going to take until tomorrow.
 
27 hours to go...

Thursday morning when I got to work, I learned the Internet was down in the building. No computer network, no web, no phones, no attendance program, no PA system. I couldn't even access my lesson plans--I store them in my network drive and don't print them out.

I remember back when the Internet was a new thing for the school. The district offered "everyone who wants one" an email address. I was one of the few people who took one. We had four computers for teachers to use. I kept my materials on 5 1'2" disks. It was a wonder when we got our first grade book program: GradeQuick. But all that was optional. You didn't have to touch a computer if you didn't want to--and most of the staff didn't want to. Eventually, as the World Wide Web merged with the Internet, the school started requiring computer usage. Everyone had to have an email address, and everyone had to check their email at least once per day. Then we were required to use an electronic grade book (but you could still use a physical book, and many teachers did). 

Eventually, we moved more fully online. Physical grade books vanished. (I don't know of anyone who uses one anymore.) The Internet powers our phone and PA system, and we were able to put phones on teacher desks. (Other professionals have had phones on their desks for over 100 years. I finally got one just after 9/11.)  Everyone has a ton of network space. The video library, once fully stocked with video tapes and DVDs has disappeared, since everyone simply streams everything. Copy machines have been combined with printers, and are networked to the computer system. All teachers have a district-issued computer and smart projector. All teachers have a Google Classroom account.  A lot of changes during my career in Wherever.

But it all means that when the Internet goes down, it's a major disaster. We can't take attendance. Hell, we can't even make copies.  And I'm not the only teacher who stores lesson plans in the network drive.

Fortunately, my first hour was in the middle of something that didn't require the Internet, so while they were working, I worked on my own connection. I have a hotspot on my phone, but the school computers are finicky and don't like connecting to anything but our in-school Internet service. It took quite a lot of finagling, but I finally got my computer to recognize my phone and got online. Yay! I could take attendance and access my network drive!

It still made for a frustrating day. The copiers were down. My desk phone was down. The PA system was down. If I moved my cell more than a few feet from my desk, it would drop the hotspot, so my phone was chained down.

On top of it all, we learned that the outage was caused by a broken cable, and it wouldn't be fixed today. Likely, we'd have no Internet Friday as well.

I was actually fairly lucky. My lessons for the day didn't require Internet access. I didn't need to copy or print anything. Lots of other teachers were stuck. One science teacher, who had an online day planned, ended up playing Mythbusters episodes on DVD for his classes.

Also, the lesson for my seniors went very well. I'd assigned them the article "It's Not Your Opinion. You're Just Wrong," so they could start to see how adding "In my opinion" in front of a statement didn't make the statement correct; you can have a wrong opinion. We discussed this, and then I had them write a set of statements: a fact, an opinion, a mixed statement, and a flat wrong opinion statement. We shared them with the class, and they actually got into it. I think many of them began to understand the point.

So that went well, at least. But it was a relief when the day drew to a close and I could shut off my hotspot.

Over the last few weeks, my desktop's Internet connection got slower and slower.  It took a while to notice because it was gradual. Then suddenly--BINK!  We had Big Problems.

My desktop stopped connecting properly with Trollboy, our WiFi network.  Sometimes Trollboy wouldn't connect at all, sometimes he would connect with a S-L-O-W connection (1 mb or less per second), and sometimes he would connect for a while and suddenly cut himself off.  The only way I could get online was by using the cell modem function on my phone.

The problem puzzled me. Every other device in the house could connect with Trollboy. Only my computer was affected. This meant Trollboy himself wasn't the problem.  Also, my computer could connect with the WiFi on my phone, on Darwin's phone, and a local Xfinity hotspot.  This meant my computer COULD connect with the Internet; it just wouldn't do it through Trollboy.  So where did the problem lie?

Darwin and I spent hours on Sunday trying to fix the problem.  We did all the usual stuff (reset the modem, reboot the computer, check the physical connections). Nothing worked. So we dug into esoteric stuff, checking TCP IP setting, resetting codes in the CMD prompt, and more.  The stuff we tried got more and more complicated, and I was digging into parts of my computer system I didn't even know existed.  By midnight, we still had nothing, and it was time to call it quits.

This morning, I did the thing every computer user dreads: I called AT&T's tech support. 

Here I discovered that if you tell the AI that answers AT&T's support line you're having an Internet connection problem, the AI runs a quick diagnostic and says, "We're finding no problems on your line.  Good-bye!" Then it hangs up on you.  I finally got through to a human being by just repeating, "I need help" every time the AI asked me what was wrong. The human in question, a very nice young man named Sebastian, listened to the details of my problem, clicked around on his keyboard . . . and told me there was nothing wrong with my WiFi, and have a nice day.

Okay, then.

Darwin said it was probably time to try a factory reset. There was a code or a system that needed a complete reboot, and a factory reset was the only way to find it.  I was coming to the reluctant conclusion that he was right. Problem was, we didn't know for sure that a factory reset would solve the problem, but a factory reset would definitely wipe all my programs, and I would spend at least a day reloading all of them before my computer would be usable again, a process I wasn't eager to endure.

And then I remembered something.  Back in the Old Days, when WiFi was a new thing, computers didn't come with an onboard WiFi receiver. You had to buy one separately and plug it into your tower.  Maybe the problem was with my computer's WiFi receiver.  If it were, a new one would probably solve the problem.

I drove down to Best Buy and snagged a plug-and-play adapter/receiver.  Back home, I downloaded its driver with my cell phone as modem, plugged the adapter into my computer, and held my breath.  The adapter instantly found Trollboy and asked if I wanted to connect to him.  I said that I did, thank you very much, and here's the password.  POOF!  I had full-blown Internet.

And it doesn't disconnect and it's fast.

Man.

Here's your Internet tip for the day. When you copy and post a URL (web address) from a friend's Facebook feed to your own feed, you'll notice you get a web address like this:

https://medium.com/@vickyalvearshecter/what-happened-when-a-trump-supporter-challenged-me-about-the-wall-e54e86a5edd1?fbclid=IwAR2-Fr6nOoiuxXV2vAg3u38rUWJZvnpoach5WJhilgHKmKqxo-luiV_octM&_branch_match_id

Now notice about halfway through the post, we have a string of letters "?fbclid". In a URL, anything that comes after a question mark isn't necessary for the URL to work. Everything that comes after the question mark is tracking information that allows FB--and other web sites--to track where you got the story from, who clicked on it from FB, and more, more, more. If you want to make it harder for FB to follow you around on-line, delete everything that comes after a question mark in any URL you post.

From the above example, you would post only this: https://medium.com/@vickyalvearshecter/what-happened-when-a-trump-supporter-challenged-me-about-the-wall-e54e86a5edd1 . The URL will work, and it messes up FB's tracking.

The FBI wants Apple to crack open an iPhone to help the FBI to investigate a case.  The judge who wrote the order doesn't seem to understand everything that goes into such a thing. She seems to think all Apple has to do is click a few mice and POOF! They're in.  This is not the case.

In order to crack the phone, Apple needs to assemble an entire team of engineers.  These engineers would then spend their entire work day writing code to bypass the phone's security system WITHOUT damaging the data that the phone contains, and it must be done in such a way that the findings will hold up in court.  ("Your Honor, how can we know that the code-breaking software didn't destroy evidence that would prove my clients innocence?  All we have is the word of these engineers--and they work for the prosecution!")

This would take a LOT of work and time and money.  And since when does a judge have the power to compel a private person or organization to spend enormous amounts of time and money to help the police?  Does a judge have the power to order a locksmith to crack a safe?  To require a car company to design and build a new car so the FBI can catch a fleeing criminal?  But this judge seems to think it's fine to require Apple to spend millions of dollars in time and money on this little project.

And this is without considering the privacy implications.  If Apple cracks this phone in a way acceptable in court, the genie is out of the bottle.  The software to do so MUST be reviewed by independent third parties AND by the government AND the system must be entered into the court (public) record.  In other words, even if Apple destroys the program, it'll still be out there, ready for the government, hackers, criminals, or anyone else to pick up and use.

For a full explanation of this aspect, I urge you to read this: http://www.zdziarski.com/blog/?p=5645

The government has greatly overreached itself.  Apple should, with the support of Senators and Representatives, fight this horrifying order or, at worst, simply claim the judge's order can't be done.

After the last Great Computer Crash nearly destroyed everything I own, I decided to look into on-line, automatic backup systems.  At the moment I'm trying Carbonite.  It has a free test period and it automatically uploads and clones everything on my computer to a remote backup site that will, in theory, let me reclone my hard drive if I ever have a massive fail.  It automatically backs up anything that changes, as long as I have an Internet connection.  I can also access the backups from anywhere on the Internet and from pads or smart phones.  It costs $60 a year, which seems reasonable.

At the moment, Carbonite is copying everything from my computer to the off-site location, and it's taking forever.  So far, it's been running for 24 hours and we've done 17,000 files with 86,000 to go.  It does seem to be monkeying with my connection, though, and I'm wondering if it's fighting with my anti-virus or just eating up too much bandwidth during the initial backup.  We'll see what happens once it's all over.

If this works out, it'll be a relief to know I can restore my computer as-is with a few keystrokes, even if it implodes.

Aran uses a laptop at school. It's the only way he can keep up with note-taking and writing, since he writes so slowly by hand.  On Saturday, I overheard him say to someone else that he had dropped his laptop at school and the screen was broken.

I was furious.  Not only had he broken it, he hadn't told me about it.  After the inevitable . . . difficulties that followed, I assessed the damage.  The computer itself was all right.  Only the screen was cracked.

I got on-line and surfed around until I uncovered the part number for a new one and ordered it.  It arrived today.  I sat Aran down with me and made him help me tear the computer apart.  First we had to pry the screw covers off with an Exacto knife, unscrew them, and carefully unsnap the plastic cover.  Then there were more screws, many teeny tiny ones, to unscrew.  We carefully extracted the screen, undid the tape holding the connector to the back, and spent considerable time trying to connect the new screen.  Finally got it, set the new screen into place, tested it to make sure it worked (it did) and screwed it back together.  At which point, the new screen refused to work. So we had to tear it all apart again to find the problem.  The connector had come loose.  We fixed it and put everything back together again.  This time it worked.

It was delicate, frustrating work, and since Aran was forced to go through it, I'm hoping he'll take extra care with his computer.

I'm experimenting with cloud storage now.

I don't actually like the term "cloud storage" or "storing in the cloud" or "cloud computing."  It makes it sound like the data are stored in some heavenly place where angels watch over them for you.  It also sounds . . . well, nebulous.  Like the data can't be grabbed at will, when usually it can.

But anyway, I'm trying it.  It started off as a way to access my network drive at work.  It's possible to access Nameless High School's computer network remotely through the Internet, but the interface is clunky and difficult to handle.  A number of times I've needed to access school materials at home, and it took a long time to deal with it.  Creating a cloud network storage area, however, would let me access materials quickly and easily, and the school allows the use of the Dropbox system on its computers.  So I installed it.

It works very quickly, and I can drag and drop and cut and paste and open and close and save exactly as if I were using my hard drive, but this hard drive I can access from any computer that has Internet access.  This is enormously convenient; I can put most of my teaching materials and lesson plans into Dropbox and get to them anywhere.  Also, I can designate any folder or file as "shared," meaning I can allow any individual I name to access it.  I have a co-teacher in my English 9 class, and I've been emailing her lesson plans and other materials.  Now I just give her permission to access the English 9 folder in my Dropbox account and save the materials there.  Much easier!

Once I started playing with that, I decided to move my current writing into the cloud.

See, I don't have a good network set up in my house.  My computers are all connected to the Internet, but not each other. This means that if I want to write on my laptop, I have to transfer the files from my desktop to a flash drive and bring that to the desk top.  The trouble with that is sometimes I lose track of which file is the latest, and more than once I've copied the wrong version over and lost work.

Now I put THE DRAGON MEN into Dropbox.  Any computer I want to use automatically has the latest version.  So far it's working very nicely.

However . . .

There are a few issues.  I'm limited to computers that have Internet access.  When Aran's at his piano lesson, for example, I like to write, but I don't have wifi there.  No wifi, no Internet.  No Internet, no cloud.

Dropbox also isn't totally free.  They don't charge for the first two gigabytes.  (Apple and Amazon give 5 gig for free--I use Dropbox because the school sanctions it.)  Then it's $10 a month (that's $120 a year).  Two gig is a LOT if you're only storing word processing files, but it's not very much if you want to store pictures or video or music.  And I refuse to pay for yet another utility.  It seems to me that my ISP (AT&T) should offer a certain amount of cloud storage space as part of my Internet access, but they don't seem to be interested.

At the moment, my relationship with Dropbox is a good one, and THE DRAGON MEN will be my first novel written entirely on the cloud.  Perhaps I'll even be able to submit it to my editor and get rewrites and copyedits through the cloud.  But I'm wary.  Nothing's free, and I'm waiting to see if Apple, Amazon, and Dropbox are just biding their time to get our society hooked on cloud storage before colluding to raise prices and force everyone to pay another monthly bill.

As I mentioned earlier, my computer was crashing at least once per day, sometimes twice, and often in the middle of something important.  I've known for some time that the motherboard is wonky, and I could have it replaced, but by the time I bought one and paid to have it installed and wrestled with all the attendant issues that surrounded it, I could just buy a new computer.

Did some searching, and found a factory reconditioned computer for much less than a brand new one.  Go me!  This one has a four-quad processor, 8 gig RAM, and a terabyte of memory. (!)  (Yeah, I'm sure in a few years that'll seem quaint, but right now that's 1,000 gig, man, and my crash-o-matic computer had 300.)  I also realized I can hook my old computer up to my TV and kill cable, which will pay for the new computer in a few months of saved cable fees.

So I ordered the reconditioned unit.

Buying a new computer is like moving.  It takes a long time to recover and find your way around the new place.  I spent two days dealing with file transfers and program uploads and working out bugs.  But now I'm good to go and coming to you from a new computer, one that won't go FOOP on me when I least need it to.

Now I just need to kill cable and I'll be all set.

Today I stopped by the electronics store to get a replacement part for a household gadget and I came across the Smartpen.  Catherine Shaffer has one, as I recall.  It's a combination pen, recording device, and computer.  You write notes on special paper, and later you can tap the notes with the pen and the pen plays back what was being said when those words were written.  The notes can also be transcribed and uploaded and emailed and so on.

The techno-geekie in me really, really wanted one.  Really, horribly, seriously wanted one.  But I reigned myself in.  I don't do enough note-taking and interviewing to justify it.  I truly don't.

But I still whimpered and drooled over it.

Whoa!

If you're part of the reading and writing and Internet community, you've heard about the Amazon.com problem.  If you haven't, short version is that Amazon removed the Sales Rank feature from almost all books that contain Gay/Lesbian/Bisexual/Transgender content.  At first they claimed it was because of the "adult content" of such books (except they also excluded HEATHER HAS TWO MOMMIES, a children's picture book), and then they claimed it was a glitch (terrbily specific glitch, if you ask me), and now they're claiming they're working on fixing it, whatever "it" is.  The trouble with this is that the books became excluded from Amazon's search function, making it almost impossible to find (and buy) them.

Various people are howling conspiracy, prejudice, and homphobia.

Me, I think they seriously fucked up.  I think it was meant to be a bit of code that filtered out erotic or other adult content so people could search for books on, say, vampires without getting erotic vampire stories (of which there are a large number).  I think whoever programmed the filter made an enormous error, released the new filter into Amazon's little search engine last February (when some people started noticing their books were excluded), and the filter grew more and more aggressive, excluding more and more books until it finally Got Noticed.

I watched the whole thing explode on Twitter.  It was like watching a few snowflakes turn into a blizzard.

See, I can't imagine Amazon doing this on purpose.  They exist to sell books.  Why would they deliberately exclude an entire section of their catalog just now, especially since they've sold such books for years and years and years?  And especially when they would have to know it would create a PR fiasco?

And since it came to a head over Easter, when no one in real authority was on duty over at Amazon, it was handled stupidly and poorly by people who didn't know what was going on once customers, writers, and activists started to complain.

Was Amazon at fault?  Yes.  Was Amazon stupid?  Yes.  Do they deserve the bad Internet press?  Absolutely.  The situation should never have been allowed to happen in the first place, and the dumb-asses have earned every shred of approbation. 

Do they deserve the chance to fix it?  Yes.  And they better move fast.

At least my books haven't been affected.  Yet.
stevenpiziks: (Signs)
As I recall, Amazon loaded up the first Kindle with a bunch of free books and newspapers and magazines.  They don't do that with the second one.  It came empty, and there were no offers of free books.

I played with it for a while.  It took a bit to figure out how the bookmarks work, but it have it now.  I haven't gone into playing with the text (making notes, selecting text, etc.).  That'll come later, I'm sure.

I downloaded two books.  One thing I like about the Kindle is that it lies flat.  I can use it while I'm eating.  Paperback books (and a great number of hardbacks) don't lie flat and are hard to use at the table, but the Kindle doesn't have that problem.

I'm liking it so far.

Okay, here's how it happened.

I bought my iPhone yesterday.  I felt I was ready to step into the world of hand-held Internet, and my old phone was eligible for upgrading.

Buying it meant first signing a contract (which I hate, but we're not planning on switching cell carriers anytime soon anyway) and then getting the phone switched on for me.  The very nice clerk transferred many files and much information, shook my hand, and said, "Welcome to the world of time wasting."

I got it home and did what you have to do in order to learn a new techno-gadget--I played with it.  I did have to struggle a bit to get it to connect to our WiFi (finally figured out I was giving it the wrong password, of which there are three to choose from) and download my e-mail (the iPhone automatically generated POP server information that was incorrect and I had to correct it manually), but once that was all straighted out, we were off to the world of tapping.

The screen is way fast and responsive.  It springs instantly to life and does what you tell it to without hesitation.  When you push a button or flick to the next menu, there is no load time.  I like that a lot.  And the special effects are cool.  Aran loves the way you page through photos by tossing them around with your thumbs.

I'm in love with the GPS and Google Map function.  No more getting lost, no more paper directions.

I also downloaded several apps to it--NPR, Pandora, Tic Tac Toe (Mackie's favorite restaurant game), New York Times, Facebook.

I'm getting better and better at using a touchpad typewriter.  Give me a couple of days and I'll be able to write stories on it.  :)

And now

The Wherever School e-mail server was flooded with virus spam yesterday.  Spam, spam, spam!  It came in the form of an e-greeting card supposedly from Hallmark.  I didn't even open it; I marked it Spam and blocked the incoming address.

Incidentally, if you've ever sent me an electronic greeting card, I never got it--I always delete them unread because so many of them are spam, viruses, or both.

And then another one showed up.  And another, and another, and another.  I spam-marked them all and deleted them unopened, more than a little annoyed.

We all later got a warning e-mail from IT that said, "Don't open the attachment!  It's a virus."

A couple of people in the building did open them and discovered to their horror that the thing hijacked their web browser and turned it into popup city.  Bleah!

This site is kind of fun:

http://www.r2d2translator.com/

You can type things into the translator and it'll translate it into R2-D2 sounds.  You can download them as MP3s as well.  I created a couple for download.  Now when a message arrives, R2 says, "You have mail."  And when my phone rings, R2 chirps, "Answer the damn phone!"

Snurched from [personal profile] tcastleb : http://wordle.net/ .  You can create word clouds there.  It's kind of cool, but snagging a picture from them is really complicated.  I finally managed it and can use it for some of my LJ entries.  Neat!
