Jab Comix Grumpy Old Man Jefferson An Adult Comic By --acf-- -

--ACF-- has done something rare with JAB Comix: he has created an adult comic that is mature not because of what it shows, but because of what it understands. It understands that getting older doesn't make you wiser. It just makes you tireder.

4.5 out of 5 dented trash can lids. Recommended for: Fans of The Simpsons' Abe Simpson, UP’s Carl Fredricksen, and anyone who has ever muttered "unbelievable" under their breath at a grocery store. JAB Comix Grumpy Old Man Jefferson An Adult Comic By --ACF--

--ACF-- taps into a very specific vein of millennial and Gen-X humor: the realization that you have become the old man yelling at the cloud, and you are okay with that. The dialogue is sharp and venomous. In one standout issue, Jefferson spends twenty panels trying to open a "child-proof" medication bottle. He wins, but the victory costs him two hours of his life and a chipped tooth. There are no sex jokes here; there is only the crushing weight of a broken pull-tab on a can of cheap soup. Fans of --ACF--’s previous work will recognize the signature blend of cynicism and hidden heart. While Jefferson is ostensibly a bastard, the comic includes silent flashbacks. We see a younger Jefferson holding a dying car, or helping a stranger change a tire in the rain. These moments are wordless and over in two panels, but they reframe the present-day crankiness as exhaustion rather than malice. --ACF-- has done something rare with JAB Comix:

In the sprawling, often chaotic universe of JAB Comix, where surrealism meets slice-of-life absurdity, few characters have resonated with jaded audiences quite like Jefferson. The series Grumpy Old Man Jefferson , penned by the enigmatic creator --ACF--, takes a beloved side character and shoves him brutally into the spotlight. The result is a masterclass in adult animation writing: raw, unfiltered, and painfully relatable. The Premise: The World Owes Him Sleep Forget the power fantasies. Grumpy Old Man Jefferson strips the concept of the "protagonist" down to its crankiest bones. The comic follows Jefferson—a retiree who has seen it all, hated most of it, and wants the rest to get off his lawn. There is no grand quest. There is no redemption arc. There is only the daily war between a man who wants silence and a universe determined to provide noise. The dialogue is sharp and venomous

--ACF-- writes Jefferson not as a villain, but as a prophet of annoyance. Whether he is battling neighborhood kids who refuse to return his shopping cart, dealing with automated phone trees that lead to hell, or simply trying to enjoy a cold beer without his neighbor’s subwoofer shaking the plaster off his walls, Jefferson is the hero we didn't know we needed. The art style in Grumpy Old Man Jefferson retains the classic JAB Comix aesthetic—bold lines, expressive faces, and a vibrant color palette that ironically highlights the protagonist’s grey mood. --ACF-- utilizes a specific visual trick: Jefferson’s world is usually depicted in warm, bright, suburban tones, while Jefferson himself is perpetually drawn in shadow or with a glare that could curdle milk.

--ACF-- suggests that Jefferson isn’t angry because he hates the world; he is angry because he remembers when the world worked better, and he is tired of pretending the decline isn't happening. Grumpy Old Man Jefferson is not for everyone. If you are looking for fast-paced action or romantic subplots, look elsewhere. But if you have ever felt a surge of righteous fury at a "15 items or less" lane being violated, or if you believe that the pinnacle of human achievement is a silent house at 6:00 AM on a Saturday, then this comic is your holy text.

CPU Stress / Torture Testing

Prime95 has been a popular choice for stress / torture testing a CPU since its introduction, especially with overclockers and system builders. Since the software makes heavy use of the processor's integer and floating point instructions, it feeds the processor a consistent and verifiable workload to test the stability of the CPU and the L1/L2/L3 processor cache. Additionally, it uses all of the cores of a multi-CPU / multi-core system to ensure a high-load stress test environment.

From the most recent "stress.txt" file included in the download:

The Prime95 Wikipedia page has an excellent overview on using Prime95 to test your system and ensure it is working properly. The tips presented there should be helpful regarding how long to run the torture test and provide a solid guideline on how long to run the Prime95 stress test.

Performing a stress test is simple:

1. Download the software and unzip the files to your desired location.
2. Run the Prime95 executable and select "Just Stress Testing" when asked.
3. The default options are sufficient to do a well balanced stress test on the system.

Upgrade Instructions for Existing Users

1. Download the appropriate program for your OS

2. Upgrade the software. Stop and exit your current version, then install the new version overwriting the previous version. You can upgrade even if you are in the middle of testing an exponent.

3. Restart the program.

4. Read WhatsNew.txt

Questions and Problems

Please consult the readme.txt file for possible answers. You can also search for an answer, or ask for help in the GIMPS forums. Otherwise, you will need to address your question to one of the two people who wrote the program. Networking and server problems should be sent to . Such problems include errors contacting the server, problems with assignments or userids, and errors on the server's statistics page. All other problems and questions should be sent to , but please consult the forums first.

Software Source Code

If you use GIMPS source code to find Mersenne primes, you must agree to adhere to the GIMPS free software license agreement. Other than that restriction, you may use this code as you see fit.

The source code for the program is highly optimized Intel assembly language. There are many more-readable FFT algorithms available on the web and in textbooks. The program is also completely non-portable. If you are curious anyway, you can download all the source code (37.7MB). This file includes all the version 30.19b21 source code for Windows, Linux, FreeBSD, and Mac OS X. Last updated: 2024-09-14.

The GIMPS program is very loosely based on C code written by Richard Crandall. Luke Welsh has started a web page that points to Richard Crandall's program and other available source code that you can use to help search for Mersenne primes.

Other available freeware

At this time, Ernst Mayer's Mlucas program is the best choice for non-Intel architectures. Luke Welsh has a web page that points to available source code of mostly historical interest you can use to help search for Mersenne primes.
