If you can address this issue, please edit the page! Thanks.

This is a scatter plot comparing how good an idea sounds to how good the idea actually is. For example, leaded gasoline sounds like a good idea due to the anti-knocking effects, but is actually a bad idea due to lead toxicity. Fake prank fire extinguishers however sound bad and are bad as they can result in a dangerous situation in an emergency. Putting mold on infections sounds like a bad idea, but this could be referring to Penicillin, an antibiotic.

The title text combines leaded gasoline and a fake prank fire extinguisher into something that is worse than either. Not only is the fire extinguisher fake, it also releases flammable material onto the fire, and there is the additional lead toxicity.

Idea What it means How good it sounds How good it actually is Explanation
Leaded Gasoline Adding tetraethyl lead to gasoline to increase performance ++ --- Leaded gasoline was introduced in the early 1920s to greatly increase fuel efficientcy and engine performance. Lead, however, is toxic. Burning the leaded gasoline in an engine releases the lead in the air. This is bad, and was known to be bad at the time, which is why there was an extensive PR campaign by oil companies to prove the alleged safety of the new product, which broadly speaking succeeded up until the 1970s.
Bloodletting Releasing "bad blood" from the veins --- --- You need your blood.[citation needed] Bloodletting has been performed as a medical procedure for at least 2000 years until it was considered pseudoscience from the 19th century, when the harmful effects became known. The idea was to withdraw blood to balance the body's "humors". Nowadays phlebotomy is only used therapeutically in a small number of cases, such as hemochromatosis (too much iron in the body).
Asbestos Mineral which does not burn and is good isolation +++ --- Asbestos was used extensively. Sadly the microscopic fibers which make up asbestos greatly increase the risk of cancer when inhaled.
Extension cords with prongs on both ends allows easy connection between 2 female connectors 0 (neutral) --- Prongs on both ends would make it easier to plug the extension cord in on either side. But once plugged into an outlet, the other end becomes a serious shock hazard.
Stair Kayaking Riding down a flight of stairs in a kayak -- --- Stair kayaking is a stunt where a person positions a kayak at the top of a flight of stairs and then, using their paddle to push off, rides the kayak down the stairs. This poses significant risks of injury or death, as well as being very bad for the kayak, which is designed to ride on water, not concrete.
Fake prank fire extinguishers --- --- The idea of placing fake fire extinguishers as a prank, presumably so that a person who thinks they are grabbing a real fire extinguisher will instead find a decoy, sounds very dangerous and potentially life-threatening for many people, and it would, in fact, be highly dangerous. In the United States, (and presumably most countries), this would also be a felony in most, if not all, jurisdictions. An example of a similar situation, although not intended as a prank, can be found here[1]

The title text expands this idea by having the prank fire extinguishers filled with (leaded) gasoline. This is literally adding fuel to the fire.

Always saying what you think ...regardless of the feelings of others or other considerations ++ -- They may reply without concern for your feelings or other considerations. Openness and honesty are seen as positive character traits in people, however taken to the extreme of always telling people what you think about them, can lead to awkward or unpleasant situations. Keeping negative thoughts to yourself or telling "white lies" can be considered a better alternative in some situations.
Replying to spammers Clicking on the "Reply" button from spam mails and writing (and sending) a reply (or worse, clicking on the links in these mails) -- --
Solar cars Having solar panels on the car's surface (mostly hood and roof) for power generation +++ - Cars require large amounts of energy in short periods of time and portable solar panels do not produce this, nor are they as efficient as fixed installations on the power grid.

There are competitions for solar powered cars, though, like the World Solar Challenge.

Heelies Heelys are shoes with a inline skate wheel embedded in the sole, at the heel. + - Heelys allow the wearer (usually children) to shift between normal walking and rolling like a roller skate. This sounds like fun but has lead to numerous injuries.
Prequels A work of fiction (mostly movie) telling the "story before the story" of another work of fiction. +++ - More of a good story sounds great on the surface, but the constraints of a prequel's ending needing to create the starting conditions of the original work often precludes organic development and causes contrived plots.
Transition Lenses Photochromic lenses in glasses get darker (like sunglasses) in bright light. + - Photochromic lenses are clear lenses that darken when exposed to UV light, then turn clear again when the exposure is removed. The advantage is that wearers of glasses don't need to buy separate (prescription) sunglasses. However, the process is relatively slow (about a minute) so not so useful when there is a quick succession of shade and bright light, perhaps in a forest or when driving. Also, car windscreen filter out UV light to some degree, which prevents the glasses from darkening as required. Finally, the process is temperature dependent, so in hot weather the glasses don't become as dark and in cold weather they might stay dark for too long.
Cutting pizza in squares Cutting (a presumably round) pizza in squares - - Most people cut pizza into wedges and hold it by the crust. Cutting it into squares allows for more pieces to be shared, but pieces near the center will have no crust to hold it by, getting cheese and sauce all over your fingers. There will also be lots of leftover tiny pieces. While hardly a disaster like the other items in its quadrant, square pizza pieces are just not very useful and rather inefficient. Cutting a rectangular pizza into squares might not suffer from the problems above, but, unless the pizza itself is square and cut only inot four squares, some people will end up with a higher crust-to-topping ratio than others.
Project Orion Study by the U.S. government looking into nuclear pulse propulsion for spacecraft. --- - Using repeated nuclear explosions to generate motion sounds bad for both the spacecraft and everything else, especially with a ground launch, but there are ways to address a lot of the concerns, so it isn't as bad as it sounds. Project Orion's theorized specific impulse and thrust would also be far higher than anything chemical rockets can accomplish. The efficiency of Project Orion is extremely low, however.
Soup Soup 0 (neutral) 0 (neutral) Soup is probably one of the oldest foods created by prehistoric cooks. Most people enjoy it, though many soups are considered somewhat lacking as a meal on their own, or bland.
Combo washer dryers A device which combines washing machine and laundry dryer into one device +++ + Better at space efficiency, but worse at each task than separate devices.
Cutting sandwiches diagonally Cutting sandwiches diagonally + + Generally regarded[actual citation needed] as the structurally superior way to slice a sandwich, providing better support in the hand and fewer all-crust bites. Required in the assembly of a club sandwich, where the diagonal components are stacked again.
Diverging diamond interchanges Road junction where the two road direction cross over to switch sides (so if you normally drive on the right, now you drive on the left) then switch back to normal after the junction - + Highway engineers believe the shape improves safety and traffic flow through the interchange because switching to the other side facilitates merging to and from the other road in the junction. However the shape appears to be insanity to an unfamiliar driver.
Toasting sandwiches Making a sandwich first and then cooking it, as in a dedicated sandwich toaster, a toaster oven or frying pan, or under a grill. ++ ++ The grilled cheese sandwich is a familiar form to most people, and many other sandwiches are improved by toasting as a final step. Others, such as the Western or club are prepared using toast. The Elvis is a specific case of a sandwich that normally wouldn't be toasted, but is improved by it - peanut butter, bacon, banana, and jelly, with the assembly lightly fried.
Crumple zones Designated areas of a car that crumple in case of a crash... -- ++ ...to absorb the energy of the crash to prevent damage to the passengers
Sliced bread Bread, sliced by the baker before packaging for sale +++ ++ It's far more convenient for making sandwiches or toast, but unfortunately pr-esliced bread will go stale faster and some applications may be better off thicker or thinner than the slices provided. Sliced bread is often used as a comparator for how good something is in the phrase 'the best thing since sliced bread'.
Pizza Flat, though usually leavened, bread with tomato sauce, cheese, and often vegetables or preserved meats ++ ++ꟶ Pizza is a widely popular dish throughout much of the world, uncontroversial except certain toppings.
Eating citrus fruit while at sea 0 (neutral) +++ The vitamin C present in citrus fruits prevents one from contracting scurvy.
Putting mold on infections Seemingly a reference to ancient practice of pressing moldy bread against infected wounds --- ++ While this sounds like a good way to get a fungal infection, with the correct mold this is a primitive antibiotic, and led to the discovery of penicillin.
Wheels on luggage Some luggage bags have small wheels inset on their frame and a carrying handle. +++ +++ A relatively simple fitting for rigid or semi-rigid luggage that substantially eases its transport through air and seaport terminals.
Heat pumps Refrigeration (or air conditioning) technology operated in reverse to heat an area instead. ++ +++ Because refrigeration is a very efficient way to move heat (as long as the cold side's temperature is high enough) this is often far more energetically efficient than directly heating a space. Reversible heat pumps also exist which can take care of both temperature needs in some climates.
Laser eye surgery Surgical techniques using lasers for precision cutting in the eyeball. - +++ This technology has substantially improved the eyesight of millions of people worldwide by allowing treatment of eye problems otherwise only corrected by lenses, or entirely untreatable. Randall has previously commented on laser eye surgery, amongst other ideas both good and bad, in 1681: Laser Products.
Fecal transplants Transfer of gut microbiome of healthy person to sterilised gut of ill person. --- +++ The gut microbiome is a collection of bacteria that lives in our guts. It can influence our health. It is responsible for last stages of digesting our food. It can also produce neurotransmitters that are carried by blood to our brain influencing our behaviour. A healthy microbiome can be destroyed by bad eating habits, unhealthy lifestyle, infections or antibiotics. The important part is a composition of different species of bacteria that compromise the biome. Sometimes it may be necessary to completely sterilise the gut and then take a sample of a healthy biome from another person. A sample is enough as the bacteria will multiply. As long as the patient eats correctly, the microbiome after transplant should develop correctly.

It sounds bad because we tend to think of our feces as something gross, to be discarded. It is called fecal transplant as our feces contain about 50% of gut bacteria, but nowadays the sample usually takes the form of a coated pill that is applied rectally.

Discussion

What was going on with this page? Sarah the Pie(yes, the food) (talk) 00:58, 19 November 2022 (UTC)

Vandalism. I mentioned it on the Admin requests page. It's getting reverted back to normal pretty quickly when it happens, but it will probably keep happening until an admin bans the person doing it, or the person doing it gets bored and stops on their own. Equites (talk) 01:05, 19 November 2022 (UTC)

are two nazis actually in an edit war or is it just one person astroturfing --162.158.63.100 01:18, 19 November 2022 (UTC)

I'm trying to combat it, but I'll only be able to keep this up for around another 20 minutes or so. InfoManiac (talk) 01:21, 19 November 2022 (UTC)

Is TheusafBot ofline or something? Generally it handles this sort of stuff pretty well--Mapron01 (talk) 01:44, 19 November 2022 (UTC)
I'm pretty sure he is. Starstar (talk) 02:23, 19 November 2022 (UTC)

This reminds me of the time I used a character in my password that was the "stty kill" character for one workstation's default console terminal settings. I normally logged in via ssh, and occasionally logged in via xdm, but the time I tried logging in via the console, it really didn't like what was left of my password. 162.158.62.180 01:25, 19 November 2022 (UTC)

Ah, the good old days when ordinary printing characters were used for erase and kill. Barmar (talk) 01:43, 19 November 2022 (UTC)

Vandals are just looking for a fun time, generally. Solution: make it not a fun time for them. Revert their edits dryly, patiently, with no particular comment or anything. Eventually they will get bored and find something else to do. Or, perhaps they'll sit there vandalizing while we revert them, we dozens against probably just one vandal. But if you make your irritation clear, that's "fun" to them, and they'll keep at it with renewed vigour. 108.162.216.239 01:37, 19 November 2022 (UTC)

I accidentally used a backspace character in a username one time. It caused all sorts of problems with my account.

Also, I've never found the whole "The trolls will leave you alone if you don't move." thing to be effective. But I've never found anything else to be effective at universally adjusting behavior either. -Master Areth

I wrote most of the current page after the first paragraph. It's a fairly sloppy first draft that could probably use some editing. Anyone who can should feel free to clean it up. Especially since the page is now protected (I'm not complaining; it was necessary) and so I can't edit it any more. Equites (talk) 05:57, 19 November 2022 (UTC)

Hi Equites, I rewrote the explanation, hope that's okay. I removed the references to the security aspect because I didn't think it was relevant. (Also pinging FrankHightower.) --Hddqsb (talk) 07:59, 20 November 2022 (UTC)
The first paragraph seems a bit superfluous - it's basically just a description of the comic, so isn't really adding anything to the explanation. Also, I think the bit about Pascal could come out of the second para - it doesn't appear to be relevant to what's going on in the comic, so it could just skip to the bit about null terminators.172.70.91.54 16:46, 21 November 2022 (UTC)
I removed the most superfluous part from the first paragraph, and pared down the explanation of Pascal strings (diff). I didn't remove the first paragraph entirely because I think it provides important context and details which are implicit in the comic. And I think it's important to at least mention Pascal strings because that sets the scene for the explanation of C strings (which don't explicitly store the length). --Hddqsb (talk) 10:08, 22 November 2022 (UTC)

Seems to be another Tech issue comic, its a tech issue with Cueball talking to Megan and the tech issue is extremely cursed. Should we add this one?162.158.22.98 06:00, 19 November 2022 (UTC)

"since there is no sequence of keys he could type that would result in a null terminator" ... I can type a NULL (ASCII 00) just fine in my editor on Linux (ctrl-v ctrl-@, the latter I type as ctrl-shift-2). However, I am not quite sure how to phrase this in the explanation without sounding like "Áctually! ...." Henri

I am amused that both in the main text and in this comment something has converted the "at sign" into [email protected].

The title text is likely a reference to this reddit post. Pb (talk) 07:06, 19 November 2022 (UTC)

I don't think that's likely... --Hddqsb (talk) 08:50, 20 November 2022 (UTC)

The only thing is I'm pretty sure it's not terribly difficult to enter a null string character, you just have to know what it is. On a PC with a keyboard that has a number pad, you can press Alt-[Number] to enter special characters using their ASCII code (Alt-65 will get "A", Alt-8 is backspace or delete, I forget which but I think BS, etc. MIGHT need leading zeroes to be 3 digits). The 0 to 31 codes - 32 is space, starting the normal characters - tend to have all the special characters, I think null string is 0? NiceGuy1 (talk) 04:14, 20 November 2022 (UTC)

It is. And (with caveats, depending upon other issues and circumstances) Alt-numpad0 would give me the null-char wherever it's practical and not blocked (intentionally or just because it isn't specifically catered for).172.71.178.206 15:25, 20 November 2022 (UTC)
I know a sysadmin friend of mine had to help a user whose account name was "🦙" (The Llama unicode symbol) and he was on a computer where not all layers between the username field and the password authentication understood unicode. Examples like this will happen in real life. IIVQ (talk) 11:16, 21 November 2022 (UTC)
Were they Spanish, by any chance?172.70.90.173 16:49, 21 November 2022 (UTC)

As Cueball is showing and handing over his laptop, I don't think the issue is about a website account (where he could probably do a password reset), but his local account on the laptop, of which he is now locked out, and hopes Poneytail can break into it? ghen (talk) 18:28, 19 November 2022 (UTC)

Good point, updated to avoid referring to "website" specifically. (Another possibility is that it is the password for some installed application.) --Hddqsb (talk) 07:17, 20 November 2022 (UTC)

"Suppose a website's registration form allows the user's new password to have up to 20 characters, but due to a programmer error the login page only accepts passwords with up to 18 characters."
There are also cases where page or application is updated with the expectation that old user accounts will still be working, but updated page no longer accepts same characters (or number of characters) than the old one, locking some people out. -- Hkmaly (talk) 01:35, 20 November 2022 (UTC)

I know from experience that (at least one version of) Windows Server allows very long passwords and that the Windows Server installer will accept very long passwords when setting up the initial admin account, but that the installer silently truncates the password to a "normal" length when actually setting up said account. If you aren't aware of this (and you have a client that uses ridiculously long passwords), you can easily trick yourself into thinking you mistyped and locked yourself out, and have to reinstall. Once installed with a shorter password, it can be changed to whatever length you want.172.70.134.122 16:16, 21 November 2022 (UTC)

Concerning the password described in the title text. If the characters are used in the order they appear in the Unicode Table the password starts with the Null String Terminator and therefor you will essentially end up with an empty password if C or a programming language is used handling strings the same way. Kimmerin (talk) 12:51, 21 November 2022 (UTC)

Good point, added (snapshot). --Hddqsb (talk) 15:38, 21 November 2022 (UTC)

I've actually had this problem long ago; I used the @ sign as part of my password, and it didn't let me log in anymore. Some systems in the good old days (I think it was an FTP server) used the @ character to separate username and password when authenticating. Also, I am still running into this problem sometimes with usernames (emails) allowing "+" in the address on registration, but not when logging in. Pbb (talk)

The @-sign is used to separate authentication and hostname information in an URL, e.g. http://user:[email protected]:port/... Within an FTP-session it was commonly used in FTP-proxy scenarios, i.e. you've connected to an internal FTP-proxy-server providing username and hostname as username in the form [email protected] (similar to the syntax used for scp/sftp) and the password as is. An @-sign in the password in the latter shouldn't have any effect and within the URL an @-character would get URL-encoded not having an effect, either. URL-encoding might be the reason for the last problem, you've described leading to a space in the stored value on the server side. Kimmerin (talk) 15:50, 21 November 2022 (UTC)

A very similar situation happened when I was network manager at Moravian College back in the mid-‘90s. A user was unknowingly typing an ASCII 0 character as a “special” character for their password, and doing it as like the 4th character typed, so the rest of what they typed (which was about 8 more characters) was simply ignored, the system thought their password was just the first 3 characters, the user was none the wiser, until the day I implemented checks to require “strong” passwords that included a minimum length. The user came to me all huffy that their password *was* long enough, but they system was making them change it, but not accepting the change. I never ask users for their password, so diagnosing the problem took a few tries, I had to think to ask them to prepend 8 x’s to the front of their password, and when that worked then I understood the problem.

NULL was also a headache for me in the early 2000’s, working with Oracle web forms, and some weird interaction of software bugs between a particular version of Safari web browser, Apache web server, and Oracle somehow allowed the string “NULL” to get into the Oracle database, breaking the SQL Boolean function IS NULL. The kludge was to change the IF [string] IS NULL” test to be IF [string] IS NULL OR [string] = “NULL” (Unfortunately not the ugliest code I have ever written) John (talk) 12:40, 25 November 2022 (UTC)

Not with null-character, that I'm aware, but when our small company (with Novell-based networking, for fule-servers, printers and most asynchronous communications to the outside world via a somewhat proprietry email gateway over a dial-up) merged into a larger company (with NT servers, and the rest, and now tied directly into their worldwide-WAN by ISDN) there were various hiccoughs in making sure existing and extended infrastructure didn't have conflicting ideas of what was acceptible in the now unified logins. (Not to mention that our username system had been initial-based, but we were now needing formats based upon full names. We had to keep both continuity (for our own long term usage validation) and a migration (to integrate into theirs) and otherwise competent users who were big experts in their own field of data analysis often could not handle the technicalities of multiple/nested logins or the logistical fallout from having their initial login profiles 'remembering credentials'. The fuss it took, until we phased through a full migration (helped by some staff turnover) and relegated the much more competant Novell system to backup/archive servers only.
And then there was the printer that aperiodically 'broke' because the replacement Windows printserver was somehow unable to pass some particular control characters (not sure if null was ever amongst them) that were occasionally used as the daily-changing hashed output to 'sign' the printouts and thus prove their legacy/providence.
I got a great deal of experience with system migrations, from all that, but also a strong dislike of being pushed into them or things that aren't themselves 'broke' being 'fixed' by mandatory upgrades. 172.70.91.58 14:53, 25 November 2022 (UTC)
