A while back I finally figured out how to use UBlock’s element blocker and promptly went mad with power. Just now I turned off all my extensions to debug something and realized how much more useable it made everything. As soon as I see something annoying I open the Ublock popup, select the element picker, click the annoying thing, and (most of the time) the annoying thing is gone forever and I never have to think about it. So here’s my shameless ad pitch for things you can do with it, other than the default “block ads”:

  • Remove all of the UI buttons that are definitely useful for someone but that you’re never going to use in your life
  • Remove UI buttons you use only once, like “register”
  • Hide the “Posts +” button in tumblr
  • Clear all of the information your credit card website tries to show you that you don’t care about so that you can focus on the couple numbers that you do
  • Send those pop-up “do you want to chat!” notifications to hell, where they belong
  • Remove various website overlays
  • Remove specifically the calorie numbers on food delivery websites
  • Hide the comments and recommended videos sidebar on youtube
  • Hide promotions that an adblocker doesn’t pick up on because they’re native
  • Hide your facebook newsfeed (if you just use it for chat/events/groups)
  • Hide discord’s sidebar when you just need one channel open and don’t want to be distracted, and then unhide it when you want it back
  • Get rid of distracting moving elements on pages
  • Hide almost all of the elements on twitter except the actual tweet, if you only interact with twitter via other people’s links and don’t want to be sucked down the rabbit hole
  • Generally hide “Related!” or “See also” or “You might like!” type distractions on sites where you only want to see what you came there for, not browse
  • Remove all of the news from weather websites so that they can actually do their job and show you just the weather
  • Remove the footer text on websites no one ever reads

I don’t think this requires being a Computer Person to use even though it has the Computer Person aesthetic, but being (to my great chagrin) a Computer Person I might be misjudging this. If you want help setting it up I will help you. If you want step by step debugging of why it suddenly break something I will help you. Two weeks away from graduating with my CS degree I have apparently discovered the obligatory Thing That A Computer Person Must Write Passionate And Slightly Unhinged Rants About No One Else Cares About. Via the power of caring way too much about something it now comes with free tech support, warranty not included, void where prohibited etc.

Further advice, because it is very non-obvious from the UI and I was very frustrated until I figured it out: the popup that shows up when you block things has two sliders. The one on the left makes your selection wide (i.e. also grabs the parents element(s)) or narrower; this is very useful if you’re trying to select something and just can’t managed to click in the exact right place that will grab the entire thing you want to block. The one on the right makes the selection more/less specific, so that in some cases when the default selection will grab all buttons of type X you can make it grab just this one button, or vice versa.

Hey yall, I wanted to make a PSA about this because it’ll be useful to many of you in the United States. You might qualify for public assistance now, specifically because of rising food prices.

The federal poverty line, the biggest determining factor for public assistance, has been kept artificially low for decades because it was based on the outdated assumption that food was the primary expense for most American households. For decades now, shelter has been the larger expense, but the federal poverty limit has still been determined based on the prices of food commodities.

Because food prices have recently gone up, the federal poverty line has gone up significantly as well. This means if you were previously slightly over the income limit to qualify for public assistance such as food stamps or medicaid, you likely qualify now. I’d like to encourage everyone who thinks they might qualify to apply for these programs. The qualification cutoffs are still absurdly low, so please be assured that if you qualify for assistance, you’re not taking something you don’t need or deserve.

Please reblog this if you think your followers will find it useful. I haven’t seen anyone talking about this, it’s just something I noticed recently, so I want the info to become more public to help people who might be struggling.

I’ve found it’s a good practice to, after doing your taxes each year, take a look at that official net income figure and go “does this qualify me for anything?”.

Check your food, your shelter, your utilities, your healthcare. If you take public transit, check that too.

It’s tax season, so it’s about that time again.

don’t get me fucking started on hard water and yes i am writing this right in the post i am so sorry op but where i live we have hard water (there’s a higher Very Hard level) so i would like to rant with you about how showering makes your skin so itchy and how you live and breath dandruff because your scalp is crying and how soap won’t rub off your hands no matter how hard you scrub and how drying yourself with a towel just leaves you clammy and how you have to wipe every surface down to combat the accumulation of limescale even though it doesn’t help so everything is spotted white and how your plants can just start dying because of the shitty shitty water and how you can technically drink tap water but it tastes terrible so you have to go on pilgrimages to mountain towns to get water from their fountains and how, since we’re ranting about shampoo, you think your hair is Irrevocably and Horribly damaged until you go to a city with soft water and wash it there one (1) time and your hair comes out silky and shiny and like a goddamned commercial yes i am still pissed knowing what my hair could be like if only i weren’t washing it with liquidized minerals

I hope I’m not barging in too hard, but I saw this in the notes and I thought I should tell y’all in case nobody has yet:

It’s possible to plumb a water-softening device into your home pipes. I have one, as do most homes in my area.

I’m *guessing* that for y’all there aren’t big displays of softener salt readily available in every grocery store and most convenience stores, otherwise you’d have found out sooner (although it’s also possible you *do* have displays and didn’t notice because you didn’t realise they were relevant to your interests, I could definitely see myself doing that), but some models run off of resin beads instead and only need the resin replaced every few years (possibly at the cost of worse taste than salt-based systems, but I’m not sure about that part).

I was doing some googling on prices recently because mine is getting old and decrepit, and it looks like it’s on the order of a few thousand if you don’t already have your pipes set up for it, or a few hundred to slot in a unit on piping already designed around it. I’m aware that a few grand is a lot of money and that many people don’t have the authority to make those kinds of changes to their homes, but it’s still good to know that it’s *possible* to have soft water without having to move to a naturally-soft area.

Changes to Tagged and Search URLs on Tumblr

Heads up! We’re changing the way we parse URLs on tagged and search pages, to properly encode/decode them to support spaces, hyphens, plus signs, and underscores. Most of these changes will be invisible to you, but if you’ve kept bookmarks or links to tagged and search pages on Tumblr or your blog, read on!

We’re going to start this process by rolling out a new setting you can enable when customizing your blog on the web:

969693ff2adc28acba72fc81a1c8ad96026065ac

What does it do? Today, and with that toggle disabled, going to a blog’s tagged URL like https://staff.tumblr.com/tagged/tumblr-tuesday would turn “tumblr-tuesday” into “tumblr tuesday” and you’d see posts with that tag. Same with search URLs. If you have that toggle enabled, that https://staff.tumblr.com/tagged/tumblr-tuesday URL will be decoded as “tumblr-tuesday” instead. If you want to link to the “tumblr tuesday” tag on your blog, you’ll have to use “tumblr%20tuesday” in the URL. But this means that if you use certain special characters in your tags, you’ll now properly be able to link to them!

The toggle above gives you early access to figure this all out. On December 1st, 2021, we’ll be enabling this behavior for all blogs on Tumblr.

We’ll update all of the links when you click on tags in Tumblr. However, if you manually added links to your tags in your blog description, theme, somewhere off Tumblr, saved bookmarks, or in posts (like a pinned post on your blog), then you’ll need to update those links if they contain spaces, underscores, or hyphens. Spaces in tags will now be encoded as “%20” rather than “-” or “+”. To do this, turn that toggle on, and click around on your tags to see if any of the URLs changed. Having this setting enabled and updating any links you’ve saved somewhere will future-proof you for when we roll this change out site-wide.

502bf463eb76bed45351e4c578357eaa93178ea0

We hope this is great news for anyone who uses tags in specific ways (we see you!) and has been frustrated that the way to link to them has been inconsistent, or just plain not working since… forever. We’re working on several fixes across Tumblr related to these inconsistencies, but the majority of them require no action on your part.

Please hit us up via Support if you have any questions or concerns about this!

shitty MS Paint 3 minutes doodle, nto entirely accurate: When you have your pinky hooked on the “bottom” edge of the phone for the extra security so it doesn’t slide out of your hand that easily, you’re wreaking damage on your hand, since the pinky is extremely askew from it’s resting position. You might have noticed that when you hold your phone like that for long time it begins to hurt, like when you are gripping a pen too tightly for example.

Green lines – the fingers are going their natural way. Red line – the pinky is way off, that’s bad.

Anonymous asked: I know you’re not an apple fan but what do you make of the iphone’s built in password manager?

ms-demeanor:

ms-demeanor:

I know nothing about it but seriously any password manager is better than no password manager.

But okay here’s what you want to look for in a password manager:

  • Portability – you log in to accounts across devices, you want your password manager (PWM for the rest of this post) to work across devices and sync across devices. For most people you’re going to want a PWM with an app, but some people like to store a password vault on various devices so they aren’t reliant on internet connection to access passwords. 
  • Security – A PWM should never store your passwords in plaintext, they should always be encrypted. Pretty much all decent PWMs use 256 bit AES encryption which I know sounds like gibberish but basically it means your passwords are locked up with really hard math and if you’re comparing options do a ctrl+f on each PWM’s feature page for “256″ to make sure it uses the proper encryption standard.
  • Usability – Some PWMs are a pain in the ass. You should try out a couple that seem like good options and figure out which one feels most usable for you. This may mean that you want a PWM with an app, or one with a browser extension that works in your browser; it may mean that you want a PWM with a very simple user interface. You may find that the paid features of a PWM make it more usable for you than the free version. The thing is that you have to USE it. Whatever PWM you are most likely to use based on the interface and features is the one you should install.
  • Port-ability – There’s always the possibility that your PWM will have an update and the update will make it unusable for you; maybe you’ll hate the layout, maybe it’ll add steps that make using it inefficient. You may need to bail on your first choice, which is why you should make sure that whatever PWM you choose makes it easy to transfer your credentials from one PWM to another. Look up how-tos and tutorials on “how to move my passwords from bitwarden to apple password manager” or “how to import passwords into firefox password manager.” Any reasonable PWM will allow you to easily export your credentials; if they don’t let you export with a simple process, don’t install it.

Features to look for:

22bd215b0350e3a24d0d62745cd77c914d8dd6dc
  • Password Generator – a tool that will create passwords of varying complexity for you. If your PWM won’t generate complex passwords for you but will only store passwords you’ve created I would recommend looking for a different manager.
  • Password Checker – a tool that ensures the password you have selected isn’t on any lists of compromised credentials.
  • Customizable Security – maybe if your desktop and your cellphone are password protected with a short timeout you don’t care how long your vault stays open. Maybe if your desktop screen lock you want your PWM to lock itself after fifteen minutes. Maybe it’s easier for you to log in with a pin than a password, maybe you want to require multifactor authentication for access. Setting your settings the best way for you personally is going to make the whole PWM more usable for you, so make sure you’re comfortable with the options your PWM allows.
  • Cards and ID – Some PWMs will allow you to securely store credit card info. This is extremely handy and very useful if you do happen to lose your cards. Some will let you upload photos of your ID or your car insurance or other things. This is also very, very handy.
  • Customizable folders – Look, sometimes you just have to sort things. Your PWM should give you the option to create a folder structure that makes sense to you instead of limiting you to predefined categories.

Off the top of my head that’s all I can think of. I’m sure that the apple password manager is better than nothing so you should absolutely use it if that’s what’s easiest for you.

649e62d5e12e79f56eac86312d12125768eaf3dc

This is why the 256 bit AES encryption is important! If the password manager is hacked through the company’s servers getting broken into or something like that nobody has your passwords. The company doesn’t even have your passwords.

Choose a good, complex, memorable password for your password manager, don’t share that password with anybody unless it’s a life-or-death situation (literally; I don’t know the password to my spouse’s password safe unless he is going in for surgery) and unless someone is able to crack your password or gains physical access to your desktop while your password vault is unlocked there’s no way to get at the passwords.

You do need to have SOME good security practices in place to ensure safety even with a password manager.

  • Don’t let people remote in to your computer
  • have your computer time out after short period
  • lock your phone and require a password to get back into it
  • don’t give people you don’t know and trust physical access to your devices
  • Use complex, unique passwords to log in to your devices and your password manager (I like doing this with song lyrics – “Nggyu,Nglud,Ngraady57″ is a rickroll and a family member’s birth year so it’s complex but easy for me to remember)

But if you’re worried about your passwords getting revealed in a data breach the way personal data gets revealed by like, target and experian and the US government then don’t worry about that. That doesn’t happen if you choose a password manager with appropriate encryption.

Let’s talk respirators!

{{previous post in sequence}}


What’s a respirator?

Short version: it’s like a mask, but better. *Much* better.

Let’s put the headline news up front: if you maintain an airtight seal at all times, a P100 respirator blocks 99.97% of incoming viral particles. [source]

Yeah. 99.97%. That’s a *lot*.

(Specifically, we are going to be talking about what’s called “elastomeric” respirators. These have a base unit made of plastic and silicone, with attachment points on the cheeks for swappable filters.)

99.97%?! What’s the catch?! There’s gotta be a catch, right?

A few catches, but generally nothing dealbreaking.

The filtered air is very dry: take frequent breaks if you can to go outside (or somewhere else with clean air) and drink some water. I work 4 – 5 hour shifts for 2 – 3 straight days a week with a respirator and no water breaks, and that’s *doable* but dehydrating.

They muffle your voice a bit more than masks do. You’ll have to speak louder and probably be more careful with enunciation than usual, and talking on the phone will be very difficult.

The 99.97% figure is for *incoming* air. An elastomeric respirator does not, by default, filter outgoing air at all. This is okay for two reasons: one, since you can’t spread a disease you don’t catch, protecting yourself *is* protecting others. Two, for even more protection of others you can tape a layer of cloth over the valve on the bottom of the respirator.

They cost more up-front (about USD$30 for a base unit and USD$11 per pair of filters), but they last for such a long time (more on that later) that in the long run it’s actually very economical.

So why isn’t everyone using them already?

Mostly because people don’t know about them. Cloth masks were supposed to be a stopgap measure until we had a chance to manufacture more respirators, but word never got out when the respirators had caught up. They do *sometimes* go out of stock still, but they’re very often available now.

Also, the kind of respirators we’re going to be talking about here are aimed at construction workers, which means people looking for “medical” masks tend to overlook them. But a particle is a particle, and there’s no reason you can’t use construction respirators against germs. In fact, in some ways they work even *better* against germs than they do against construction fumes.

(Edit: Okay, yes, also they look funny, but people in 2019 would have told you masks looked funny too.)

What do I need to know about how to wear them?

First, check the fit. Take off your glasses if you have them, then put the base unit on and adjust the straps until the seal is airtight without being painful. You won’t be able to get an airtight seal if there’s facial hair in the way: you’ll need to at *least* trim it down very far, and probably shave it.

To confirm that the seal is airtight, there are two methods depending on whether the filters are attached right now.

  • If the filters are *not* attached: cover the attachment points with your palms and try to breathe *in*. If you can’t, the seal is airtight. (Except for the attachment points themselves, of course: *those* are big gaping holes in your seal if they don’t have filters on them. But we’ll be fixing that soon.)
  • If the filters *are* attached: cover the valve at the bottom with your palm and try to breathe *out*. If you can’t, the seal is airtight.

(You’ll want to confirm the seal every time you put the respirator on.)

Next, take a pair of filters and screw them onto the attachment points. (This is much easier to do if you’re not wearing the respirator while you’re doing it.) Be sure to screw them on very tightly, otherwise they might fall off. (I didn’t screw them on tightly enough my first time, and it was pretty scary when one of them fell off in the middle of a crowded restaurant. But now that I’ve gotten them on correctly, they stay put.)

Now you can wear it. If you have glasses, take them off first, then gently rest them on top of the respirator’s nose once you’ve put it on. Check the seal as above to make sure it’s airtight.

Once a week or after every outing, whichever is less frequent, wipe down the silicone (the part that sticks to your face and forms the seal) with some mild cleaning solution to keep the skin oils from building up. You can also wipe down the outside if you are concerned about fomites, but note that of the two styles of filter (more on that later) you can *only* wipe down the plastic cartridges, *not* the pink cloth circles. Here is the official manufacturer’s guide on cleaning these respirators [link]: note that “quat” is janitorial jargon for the type of cleaning solution that Lysol wipes are dipped in.

(Bonus tip: if you’re having trouble sourcing disinfectant wipes, look for bottles of “quaternary ammonium” *next* to the barren disinfectant-wipe section at the grocery store, put it in a spray bottle diluted to the level stated on the bottle instructions, then heavily spritz a paper towel with it. Voila, a disinfectant wipe!)

According to the CDC [link], the filters last somewhere between a month and a year depending on how much you need to conserve resources and how well you can avoid getting them wet or dirty. The main limiting factor on longevity is that the filters get clogged with fumes and dust from the construction work: if you’re not *doing* construction work or similar fume-heavy activities, they can keep going for ages. If you can still breathe through it and the filter hasn’t been wet, you’re good.

Where can I get them?

Depends on where you live.

Base unit (currently USD$27.81): https://www.amazon.com/3M-Facepiece-Respirator-Respiratory-Protection/dp/B008MCUT86

Filters:

If possible, I recommend getting them from ULine: https://www.uline.com/Product/Detail/S-20007/Reusable-Respirators/3M-7093-Hard-Shell-Particulate-Filter-P100

ULine has the water-resistant plastic-cartridge filters, is a very reputable dealer, and sells for a good per-pair price. The only trouble is that they sell 6 pairs at a time: split a pack with a group of 3 people if you can, so that each of you will have one spare set.

If you really need a smaller pack or if ULine is out of stock, you *can* get the pink-circle kind from Amazon: 3 pairs for USD$28.90 (https://www.amazon.com/3M-2091-Particulate-Filter-Pairs/dp/B00KYX8JBU), 1 pair for USD$12.80 (https://www.amazon.com/3M-50051131070009-Particulate-Filter-2091/dp/B07571LKP4).

The pink-circle filters are *not* water-resistant: try not to stay out in the rain very long or otherwise get them wet, and don’t try to disinfect them (just avoid touching them instead, and wash your hands if you do have to). Also, counterfeits occasionally slip into Amazon’s stocks: try Amazon filters on when you first get them, and if you can still smell anything through them, demand a replacement. You should *not* be able to smell anything through a true P100 filterEdit: @nuclearspaceheater, who is a more experienced respirator user than I am, reports that many genuine P100 filters *do* let some scent through: I merely happened to have filters with some extra vapor filtration. I’ve seen reviews saying that fakes are suspiciously light, but it’s hard to tell if you don’t already know how much they should weigh, plus that *also* might have been a vapor-vs-nonvapor distinction. It’s possible that the people complaining about counterfeit filters from Amazon are just straight-up mistaken and they’re all fine, but I would still go with ULine for the water resistance if nothing else.

Canada:

Base unit (CAD$44.19): https://www.amazon.ca/dp/B008MCUT86/

Filters:

Canada has branches of both ULine and Amazon. Read the tips I gave the Americans on filter selection: the same things apply.

ULine (6 pairs for CAD$89): https://www.uline.ca/Product/Detail/S-20007/Reusable-Respirators/3M-7093-Hard-Shell-Particulate-Filter-P100

Amazon (2 pairs for CAD$24.71): https://www.amazon.ca/Particulate-Nuisance-Organic-Release-2097PA1/dp/B007STCT00/

Amazon (1 pair for CAD$16.95): https://www.amazon.ca/3M-2097-Particulate-Filter/dp/B00328IAO0/

Other countries:

I don’t have links for these on hand. For the base unit, check your hardware and general stores for “3M model 7502 respirators”; for the filters, look for “3M bayonet-style P100 filters” and prefer the plastic cartridges over the pink circles if possible. If you can’t find any of those, try looking into other elastomeric respirators, but I don’t have any experience with other ones so you’d be on your own there. Remember that you should not be able to smell anything through an airtight P100 respirator: if you put the filters on and can still smell stuff, something’s wrong with those filters, go back to the seller and get them to either give you a better set or refund you. Edit: This is not necessarily true and indeed there might not be counterfeits at all: check the edit in the USA section for more details.

Getting a respirator has been a life-changer for me, and I hope it can help you too. If you found this useful or know someone who would, please let people know.

Postscript, 2021-09-14: It has been my experience that nuisance-vapour filtration wears out after 3 – 4 months. If you value its psychological benefits (I don’t know about you, but nothing reassures my subconscious about air quality quite like respirator-specific anosmia), or have additional uses in mind for your respirator such that you need nuisance-vapour filtration, I recommend planning to replace your filters about that often.

Also, here is a nice pocket umbrella I got to protect my non-water-resistant filters from unexpected rain. No more standing at the threshold of my workplace stuffing my respirator into a plastic bag! It makes a pretty good parasol, too.
