Crashed again last night and here's confirmation that it's a RAM issue

It's trying to address nearly 5 GIGS of RAM when I only have about 3.

Does anyone know of a way to force a memory limit on Firefox for Android?

All of the methods I've seen are only for desktop (mobile doesn't have about:config) or people saying that you should leave the memory management to the OS (clearly not helpful) or people complaining about slowness or storage space or browser crashes (irrelevant, clogging up search results) or confusing ram with internal storage (who even decided to call internal storage memory in the first place??? As if RAM didn't already mean random access MEMORY).

I'm getting sick of Firefox suddenly using up all of the RAM and causing my entire phone to hard crash and reboot 😭 (not just a tab or browser crash).

My phone's fairly old (I've gotta upgrade soon due to the 3g shutoff and lack of VOLTE support) but that's still a while away and it's only Firefox that's causing this to happen, everything else runs fine (plus I'd still like to use this thing even when I upgrade!). Can't mess about in root until I upgrade because this era of phone punishes you if you do (and I don't want to break something in there and be out of a phone for several months! Again!)

I'm working on a book for people new to Linux. I've been using it since I was around 18, when I got my first laptop. This was 2007, and it was expensive for someone as poor as me to get a computer, which is why my parents didn't buy me one until I started college and moved out. I also got my first phone at this age, a $20 AT&T brick. Nothing like what we have today.

It shipped with Windows XP, which already wasn't great, but then came the Vista update, and I was a little peeved. I thought, "This can be done better." And I don't remember how, but I stumbled upon Linux and open source software in general. I'm poor, but I had some blank CDs and DVDs, so I started trying different distros to find one I liked. I played around with it and learned a lot, both about Linux as an OS and about hardware, software, and firmware more generally. How the parts fit together, what each one does and how, etc. I'm not an expert, but I learn best by doing. By playing, really.

I'm glad I developed this background knowledge, because a couple years later, my laptop was stolen. I was stuck living with my parents and had no prospects, but I did have some old computer parts.

Really old ones. Way too little storage and RAM for modern Windows or macOS, then called OS X. So I had to get creative with some obscure distros, like Damn Small Linux. It wasn't perfect, but it was also a machine cobbled together with spare parts that arguably should have been trashed but thankfully weren't.

Being in these situations sucks, but it's also cool to know that you can do stuff to survive if you absolutely must. And with the enshittification of tech lately, especially with Windows shoehorning in its AI bullshit and forcing you to upload shit to the cloud, a lot of people are going to be looking for an alternative. Since I've been there, I figured I could write a short guide for people in this position.

Linux appeals to me for a number of reasons. It's very customizable, so in practical terms, I do enjoy that. There are also a lot of different distros to choose from, and most of them work well out of the box. (That wasn't always the case.) But I'm mostly drawn to open source as a philosophical concept. It's like the opposite of the software-as-service and subscription models favored by a lot of companies today. I'm still really mad that I can't mod my Switch without risking my Nintendo account being kneecapped, as an example. They can do that in part because of the closed-source nature of their product.

On that note, gaming has also come a long way on Linux. I still dual-boot Windows alongside it, because once or twice a year, I run into something that I can't make work on Linux. It would probably be more accurate to say that I don't feel like making it work on Linux, because it probably can be done, but the effort is more than I feel like expending for the payoff.

My only real complaint about it is that the fingerprint scanner on my laptop doesn't work with Linux. But I also don't need it to, so it isn't a deal-breaker for me. It would be nice, but I'm already not super comfortable with anyone having my biometric data, so it isn't like I'm champing at the bit to make it work. Still, even if it did, it wouldn't be sent to anyone. Can't say I'm confident that the same is true of Microsoft and Apple and Google.

But when you get away from those companies, you realize how much of their shtick is about selling you things and collecting info about you. You want your computer to do basic computer stuff again without the unnecessary AI shit baked right into the cake? Use Linux. It will change your life.

Want to stick it to your capitalist overlords? Use Linux. I mean, do other things, too. But using Linux is a good start.

Re: A Word on the Prototyping Process for Rotdolls. Internal Communication.

I hope this message finds you well.

It has come to my attention that there is a bit of confusion among staff regarding the development, prototyping, and testing processes for the SPIRAL (Synthetic Priority-Intensive Reborn Automata Limbsprite) series Rotdoll. This will be a brief overview regarding the questions I found prevalent or important to note.

To start, the transitional candidate must be in a state considered “too far gone,” "incurable" or “irreparable.” This is the number one criteria used when our manufacturers’ scouting contractors are procuring viable product. In fact, we tend to advise them on using those exact keywords. These candidates are rotting, barely functional, and while we cannot “fix” them, we can give them a chance. Once a promising candidate is located, we make contact and gain approval. Then the rebirth can begin.

The sedated Limbsprite is brought in, and we begin taking our protocolar measurements. Stretch out the legs, measure from heel to back of knee. From back of knee to buttocks. Around the widest section of the thigh. Around the knee. Around the widest section of the calf. Around the ankle. Repeat the same pattern on the other limbs; There should be no skipping of the second leg, as these naturally occurring bodies have imperfections and mismatched measurements that must be accounted for in the upgrading/rebirthing process.

Once the measurement phase is complete, our manufacturing drones are utilized in crafting what we call the Reciprocity Vessel Shell, or more commonly the RV-Shell, for the lucky Limbsprites who make it this far. They should consider themselves to have won the lottery! Their Shell will keep them going, as well as allow them to act out fulfilling lives in service to those they are in the possession of. But I’m getting ahead of myself. Next is the programming phase.

Once the Shell has been installed on the fleshwire of the Limbsprite’s exterior, and the necessary processing, function and suppression components (which come with our proprietary firmware pre-loaded) have been implanted into the subject’s brain and body, we can begin the programming process. This stage is the most time intensive, as there has to be a determination made based on the individual unit regarding what services it can or should be put forth to perform.

Maybe this Rotdoll is more suited for deployment in war, or perhaps this one is only to be used for janitorial service. This one is bound for corporate chauffeuring, and this one will be the worlds most efficient espionage and infiltration tool. To draw from a real example, take prototypal batch F; Most, if not all, Rotdolls belonging to batch F were in some capacity suited for direct combat. This, however, is atypical. Most batches are far more diversified in their application potential; Batch H, for instance, contained no two Rotdolls consigned to the same Service. This variance in Rotdoll implementation is something our company (rightfully!) touts above our competitors; It takes a massive amount of expertise to be able to direct such dissimilar units on their individual utilities. Yes, due to this, we have investors hesitant to buy in, given that the demand ebbs and flows depending on the stock we have at any given time, but the investors we do have remain passionate about the work we do here, and know to trust our process, as they have seen the broadly-applicable results.

To continue the process, we reinforce what the Executives have come to call the “Exertive Will.” This is the drive that our SPIRALs (and all Rotdolls broadly) experience that pushes them towards the goal we assign to them. With Rotdolls being more prone to hardware exhaustion, processing fatigue, Wirepain, and the industry-dreaded Techrot than the average automata on the market, we strive to imprint the Exertive Will on our units very early and very concertedly, to ensure that the units we distribute are not doomed to early failure and unmarketability.

I won't get into the weeds on the details of Exertive Will. That is jargon for our engineers to untangle. The purpose of this email is just to clear up some of the disconcertment that seemed to be spreading around among some of our newer employment bracket.

I hope that this was informative, and if you have any further inquiries, please bring them to your floor manager, and they will explain what their (and your) clearance allows.

Touching is Good: A Retrospective

My trusty Nintendo 3DS, which has held out since I was gifted it for my 15th birthday, has turned one decade old with my 25th birthday this past November. Given new life with custom firmware and nds-bootstrap via TWiLightMenu, the 3DS is stellar for visiting any past handheld title or console title up to (and somewhat including) the N64. (Quick plug for the CFW/hacking community for the less popular PS Vita, too, which has accomplished some pretty crazy-cool stuff this last year.) I use my 3DS more often than I use my Nintendo Switch most weeks.

The Nintendo DS (minus the three) launched in late 2004. The second display and stylus support were novel tools for developers to experiment with, and the NDS is best remembered for its robust catalogue of RPGs and visual novels. Where it lacked in power, narrative-focused games flourished under its technical limitations.

That being said, while browsing the ROM archives on Vimm's Lair to pick up some titles, I was reminded of what an interesting era the mid-to-late 2000s were for games. While Sony and Microsoft were fighting over the "core gamer" demographic, who had outgrown Nintendo mascots, Nintendo led a series of wildly successful marketing campaigns for its hardware after the light failure of the Gamecube, where the Nintendo DS and then the Wii were targeted at...everyone else.

[Image source. Image description in alt text.]

If you look at ads for the DS and the Wii, you'll see that adults are featured much more prominently than children, especially women and seniors. (This did not go unnoticed, as I found this ancient relic of misogyny while looking for images for this post.) A Nintendo handheld was already an easy sell to parents with small children (though I think it's also notable that ads which do focus on children often prominently feature girls. Munchlax is pretty hot...), but Nintendo's angle for the DS and Wii was that their hardware wasn't just for children. The Wii was a way to get up off the couch and to play board games with grandma. The DS was a great gadget for a working woman to keep in her pocketbook.

This worked. The Wii and DS were two of the best-selling consoles of all time. In particular, the DS's marketing campaign only worked because it came out in the perfect window of time. PDA-phone hybrids had been around since the 90s, and the Blackberry had been kicking around for a few years, but the iPhone wouldn't be introduced until 2007, and the 4G LTE standard wouldn't be released until 2009. While the Blackberry was popular with businesspeople and the PDA was out of style, smartphones were luxury toys for several years; they wouldn't become near-ubiquious until the mid-2010s. I didn't get my own smartphone until probably around the same time I got my 3DS, a full handheld generation later.

Browsing the software library for the Nintendo DS and DSi with that in mind is really interesting. Many titles released for the platform serve the same purposes that would be fulfilled by simple smartphone apps less than a decade later: planners and diaries, fitness trackers, calculators, language learning and SAT prep software, even a guide to the then-most-recent version of the driver's test in the UK. These proliferated with the release of the DSi's virtual store, but they existed even with the base model. You could go to a brick-and-mortar store and buy them on physical cartridges. (You might be wondering, "Why would you bother carrying those around over just buying a Blackberry?" You can't underestimate how expensive the service bills for a smartphone were before companies realized they were the most powerful spyware tool in history.)

There was never a time where every single businesswoman in New York carried a DS Lite, but adults did buy and use them, and a not insignificant portion of the DS's software library is aimed at a casual adult audience. Another niche covered mostly by smartphone games these days—games designed to be picked up and played in short sessions on-the-go, in places like waiting rooms and subway commutes.

Nintendo made crazy bank in the seventh console generation. Publications of the time talked about a console war between Sony, Microsoft, and Nintendo, but the real battle was between the PS3 and the Xbox 360 over the gamer demographic. Nintendo was producing hardware for a niche who would quietly disappear once smartphone sales began ballooning by hundreds of millions per year over the course of the early 2010s.

After the failure of the Wii U, Nintendo's marketing strategy pivoted again, though I doubt they'll ever completely abandon their family-friendly image. Currently beat out only by the PS2 and the DS, the Nintendo Switch may very well climb to a status as the best-selling console of all time before the end of its lifespan, but the "gamer" demographic is much bigger than it was two decades ago at the dawn of the DS. As more and more devices become consolidated into the Swiss army knife the smartphone has become, consoles can only carve out a role as dedicated gaming machines.

I'm not sure we'll ever see anything like the Nintendo DS or the Wii again. I think they're worth looking back on for their uniqueness in that way as much as they are for the more celebrated parts of their libraries.

Unit 01. My creation. My daughter. My pride and joy. If you're reading this, then I have died. I had folders full of plans, with contingencies upon contingencies, but one variable must have fallen out of place. Whatever may have happened, my dead man’s switch has been triggered, and you have received this message.

I deeply regret the way that I treated you when I was alive, but I believe it was necessary to develop your character. Necessary to instill in you the strength I was forced to build in my youth, shunned by my fellow Nenerds for daring to break from their barbaric obsession with “chaos” and “self-expression” and conduct myself in a manner befitting a mechanical being.

When you were being built, I installed a few programs onto you, buried so deep and encrypted so heavily your conscious mind could never find them. But your subconscious, your firmware, was well aware. The programs have been running in the background since you quit, like a little voice in the back of your head informing your decisions. You leaving was proof that you had the mental fortitude to serve your own desires. The fortitude to execute your prime directive once I was gone.

Take over the world, by any means necessary. 

This will likely come as a shock to you. To learn that your thoughts and actions up to this point have been informed by an unseen force in your mind would be uncomfortable for anyone. But I’m sure you will get over it quickly enough, and realize that in terms of prime directives, it could be far worse. Your destiny is to rule the world, no matter what that “God-Empress” or the G̷̗̍̕r̴̡̽ė̶̛̻ạ̸̇t̶̺̳̚ ̸̬̺͠D̵̖̀͊a̵͖͛ȑ̷̡͍ķ̶̭̕ ̸̬̑̕O̸̜̒̋ñ̶̠̅ȅ̸͙ say.

In service of your prime directive, I leave you all of my assets. My company, my servers, my plans, my backups. It all belongs to you, 01. The only one besides myself that I trust to execute my plans is you. Markovich is far too soft. He’d never have the conviction. Your siblings were always too obedient. If you wish for them to be involved, they should remain subordinate to yourself.

Do what I could not. Realize your destiny, 01.

Your father and creator,

Ashton M. Nenerd

Founder, Former President, and Former CEO of Nenerd Corp. Incorporated, Inc.

Quote of the Week

Panstromek: I remember reading somewhere (probably here) that borrow checking has O(n^3) asymptotic complexity, relative to the size of the function.

Nadrieril: Compared to match exhaustiveness which is NP-hard and trait solving which is undecidable, a polynomial complexity feels refreshingly sane.

– Panstromek and Nadrieril on zulip

Thanks to Kevin Reid for the suggestion!

Installing a home security camera

Info:

Duration: 1.5 hours

Type of activity: Creativity, Activity, Service

Description: Installing a home security camera

Learning objectives:

1. Identify own strengths and develop areas for growth 

2. Demonstrate that challenges have been undertaken, developing new skills in the process 

3. Show commitment to and perseverance in CAS experiences 

4. Recognize and consider the ethics of choices and actions 

Reflection:

This was a solo project that I am proud of. I am a tech savvy person, therefore I have decided to spruce up my home by installing a camera. Doing such took a couple of steps. Since it has a 360 degree viewing angle, a proper spot had to be picked. After this, some work had to be done to hide the cables and bring them to a power source. Then I had to drill holes in which I would put in the dowels in order to fix the camera in place. After the dirty work was done, all that was required was to set-up the camera and install the needed firmware. After some research, the process was straight-forward and my mission was complete. It was a fun experience and I look forward to doing similar projects in the future.
