About the disappearance of jobs in less than a second, and why automated scripts can be detected

Greetings!

Just for the fun of it, I asked Google about how Frontline detects automatic scripts and bots that snatch jobs in a millisecond. As we know, using this can result in a total ban of the substitute teacher from Frontline itself, not just the district.

Well, the AI answer stated the following. Of course, AI can be wrong, but the anwer really makes sense:

Frontline Absence Management (formerly known as Aesop) detects bots by tracking inhuman behavior patterns, unrealistic server request speeds, and browser fingerprints. Because Frontline's Terms of Service explicitly prohibit using software or "bots" to automatically accept jobs, they actively monitor the system for automated scripts.

Frontline's security infrastructure identifies automation tools using several primary technical methods:

  1. Request Frequency and Speed (Rate Limiting)
  • Unnatural Refresh Rates: A human manually refreshes a browser page or the mobile app every few seconds at most. If an account sends requests to the server multiple times per second (or perfectly every 5.0 seconds for hours), the system flags it as a script.
  • Instantaneous Acceptance: When a job is posted, a human must look at it, process the information, move their mouse or finger, and click "Accept." If a job is accepted within milliseconds of appearing on the server, it triggers an automated alert.
  1. Behavioral Biometrics
  • Lack of Mouse Movements: Humans interact with web pages unpredictably. They move the cursor across the screen, scroll, and hover over elements. Bots interacting directly via the web HTML or API do not generate these organic movements, making them easy to spot.
  • Keystroke Dynamics: When a human types a login or password, the time between keystrokes varies. Bots input text instantly or with mechanical precision, which behavior-tracking software flags instantly.
  1. CAPTCHA and ReCAPTCHA Challenges
  • Frontline integrates tools like Google ReCAPTCHA to separate humans from software.
  • These tools run background checks on your browser history, Google account login status, and micro-movements. If the background check is suspicious, it triggers a visual puzzle that standard automated bots cannot solve.
  1. Digital Fingerprinting and IP Tracking
  • Cloudflare / Web Application Firewalls (WAF): Frontline runs behind security layers that scrutinize the incoming connection. They look at your browser’s "user-agent" string, extension data, and hardware configurations.
  • Data Center IPs: Many custom scripts or hosted bots operate from servers (like AWS or DigitalOcean) rather than normal residential internet providers (like Comcast or AT&T). Frontline automatically blocks or flags requests originating from data centers.
  1. API Discrepancies
  • Many bots try to bypass the visual webpage entirely and send data requests directly to Frontline's backend API.
  • Frontline routinely changes its internal API endpoints, security tokens, and encryption headers. When a bot tries to use an outdated or structurally incorrect API call, the server recognizes it as unauthorized software.

I figured out how one is on a school's preferred list

It's very difficult this week to get even positions that are far ahead of time. As soon as the apps alert of a job, it it taken before one can react. One has better chances going to the website and refreshing every 5 seconds.

But there is a school that I note posts jobs, and I can delay about 30 seconds and the job is still there. Every single time I click on a job from this school, I have a 100 percent success rate in obtaining it-even during this week where many subs are idle because of little work and have a chance to be attentive to the apps and computers.

For 2 consecutive years, I have had about 55 out of 180 assignments at this same school; none of them were obtained by direct teacher requests. The app pinged me and I always get these jobs. Not so in any of the other schools. Espacially middle and high schools. These are so popular that they are snatched even before the app notitication fully appears. In the other schools, half a second of a delay is too late.

It seems that apps are way slower to notify than the old refreshing method directly from the website

Since virtually all of the jobs that come from the phne apps are taken when I click the accep tbutton, and since I am at home all day, I now use the old way of getting jobs: going directly to the Frontline website and refrehing ever 5 or 10 seconds. And yes...a job popped up on the website, and I immdiately grabbed it. Neither Subfinder nor the Frontline app notified me at all that this job was available.

With SubAlert being gone soon, and the Frontline phone app being unreliable, going directly to the website and refresing like in the old times is the way to go for those of us who don't rely on being on preferred lists or teachers requesting us directly.

I really preferred Jobulator. It worked so much better than the current Frontline app. At least this was what I experienced.

Predictions from 1965

The pictures are from a 1965 magazine. Look at what was predicted.

Now, in 2026, take a look at how many of these predictions came true. Virtually all of them.

The ad is for a single channel Tx with throttle control. The 125 dollars of 1965 is about 1300 dollars today.

The raids-one year later

It has been about a year since the "Hot Summer" in which the ICE raids were daily news and restaurants in my area closed doors like if it were the pandemic once again. Service was like those COVID times-only to go and the dining area locked.

The park from where I fly RC planes (Whittier Narrows) was dead, except the RC pilots, the shooting range and baseball. No soccer. No picnics.

A year later (now) it seems as if the raids did not happen at all. The restaurants are now fully open. The weekends are now back to full life at the park, Soccer players and picknickers are back in full force.

I am aware that, even with the apparent calm, the raids haven't stopped-it seems they are not as publcized as they were last year.

I have seen almost no laborers waiting for jobs at the Home Depot. Before the raids, there were lots of them.

As for me, I haven't encountered a single ICE agent at all .

Regarding the E-Flite Me-262

Greetings!

I know the box and as state that it’s an UNX.

In my opinion, it’s not.

It is already on the league of those FMS 800 mm T-28s and Corsairs. It is large for a UMX plane, can weigh over 250 grams with an 850 mAh battery, and does fly very fast and has a fast landing speed.

I fly this one a lot and is a delight to fly it. But again, to me it’s no longer a UMX like the UMX Pitts or Timber or P-51 in terms of size.

Just saying.

But I must say that it’s a marvel of technology. Imagine a small size, electric EDF Me-262 in 1985? That would be impossible. What we had was a 17 pound, twin ducted fan model powered by two large glow engines which required months to build and was about 70 inches in wingspan.

In an ideal world, the following would be a response to a flimsy or anonymous complaint. The reality, of course, is different.

In an ideal world, the following cartoon shows how ian employee accused anonymously would be handled. As we know, substittue teachers can be fired on the basis of any complaint, and often we are never told who accused us or even the specifics of the complaint. Just watch this clip and see how the employee handles an anonymous complaint.

Of course, in the real world we wold be immediately asked to leave the site and blacklisted. We would almost never afforded to defend ourselves against any accusations and are summarily banned from a site or terminated from employment. The clip is about dealing with a boss in the corporate world, but the situation-people complaining about us without our knowledge-is common in the world of subbing as well.

https://www.youtube.com/shorts/0G_7PzEda1Q

In a heaing that I had with an admin 16 years ago, I got this same response from the admin: I am not to know who complained about me and I was not entitled to even be told a reason but I was told a vague reason "out of courtesy" but admins did not even have to have any meetings with me to discuss a complaint and a ban. Yes, this is what I was told flat out, that I was not even entitled to know a reason.

Just like in the video, how can we fix the situation at school and improve our skills and classroom management if we are not told the specifics and what we did wrong so it won't happen again? As the vidoe states, "how can I fix the problem if I don't know what's happening?"

In another meeting with the same HR person, I was told that I was a bad example to the class. I asked for specifics but I was told that I was not entitled to any. But unlike in the cartoon video, I was not told this professionally and in a calm voice. I was treated like an incompetent child and lectured at like one.

Good night.

My job description: video presenter

Greetings.

I have come up with another job description for this job: video presenter.

It has come to the point that all I do every day is just present slide after slide after slide on the iPad and let the one in the slides do the teaching.

The entire lesson is on the iPad. All I do is mirror it on the main projector and that's it. I just keep order while the students watch. I don't even have to do anything besdies keeping order.

Keepiing order. That is what it has become. Keeping order.

Opening routine: Display the good morning slides, play the flag salute, play the days of the week, play the opening songs, play Jack Hartman, play Danny Go, display the calendar, display the class rules.

Math: display slides. Display the pages. Display the examples. Play video about the lesson and let the narrator teach. Go over work with the projector. Do iReady math. When done, do things like Prodigy or Kahoot or Geoboard or any other math app.

Reading: iReady, google classroom, Epic, etc. Walk around while the students to their thing on the iPad.

Writing: Canva, Book Creator, write drasft on paper and then type it on the iPad. Writing is, in most cases is typing the assignment or dictating to the iPad what the story should look like.

Art: watch video of a project and have them follow along; let the narrator teach the lesson.

Social studies or science: More iPad. More videos. The textbook is now in Google classroom. Follow what the slides instruct to do.

Brain breaks: more Danny Go or similar.

And this is lower elementary, by the way. All instructions are projected on the iPad.

It's like working in one of those movie theaters where all one does is present the movie. It is the same here. All I do is present video after video after video after video after video....

Rest time: another video with soothing music.

Social studies: Book on Google Classroom. More screen time. Students type answers.

Upper grades: More Canva and Google Classroom. Math is usually Desmos. Then it's Edpuzzle for any other assignments-watch videos and answer questions on Canva. IReady reading or math.

High school-more Canva. Textbook is online. Watch video or read online. Answer questions on the chromebook.

I am not teaching anything. I am just presenting slides and videos, and letting the presenters do the teaching. This is the lesson plan. Show slides on teacher's iPad or have a student project them. Follow the slide lessons and play the videos.

What is so frigthening is the hyperdependence of these students on their iPads or iPhones to function at all. Writing is declining-there are times in which I cover upper grade classes and the writing is difficult to read because they have spent more time at the keyboard than practicing writing. They expect the iPad to write the essay for them, to solve things for them.

The Frontline app has been nothing but horrendous ever since I installed it 3 months ago.

Ghost notifications (the app notifies that there are jobs but then I get that blank "No jobs available" screen. Many times it has been this way.

It is also so glitchy and unpredictable.

About 20 minuts ago, I accepted a job at a school I have lots of prestige points with (aka good rep). via Frontline. Well, I accepted the job and got the confirmation number.

Guess what....for about 10 minutes, the job does not show on my list of scheduled jobs and even shows that it is available. I check on my district's email to see if it has been canceled, but no. It hasn't. Then I click on the "accept" button but states that another substitute has taken it (the oops notification).

I keep refreshing and no, the job is not in my schedule. It is not listed on SubAlert either.

Well, about 15 minutes later, the job finally is listed on my schedule.

It happened also a week ago when I got an assignment via Frontline. The same glitch. The same errors.

At least, for me, when we had Jobulator, I never got glitches, and the app, to me, was very easy to use and I could accept jobs very quickly, without any of the issues that are so present on the Frontline app. I REALLY, REALLY hope that SubAlert is not blocked because SubAlert has been FAR, FAR, FAR more effective for me. In fact, about 95 percent of my jobs have been obtained via SubAlert. Back when I started using smartphones in 2013 and got the Jobulator app, it was a great tool to have so I would not have to log on Subfinder. It was that effective.

When we switched to Aesop, I found it far more convenient to use, along with the Jobulator app. SubAlert and SubSideKick covered all bases and I could work every single day without any struggles.

Now that we are down to SubAlert and that Frontline app, it has gotten much harder to snag a job for me, but I still work every day.

If Frontline is going to block SubAlert as well, I really hope that Frontline polishes that app and makes it error and glitch free.
