== I²C over COM port ==


== Is this bug in the google search ? ==
hello, does someone by chance know of a program or a library that can bitbang the I²C protocol over an RS-232 port (or, rather, an FTDI style breakout board with TTL levels), for communicating with I²C devices, preferably under Linux? I'm aware of the electrical differences between I²C and TTL ] (]) 04:29, 9 July 2016 (UTC)

Is it possible to measure an L.E.D.'s actual watt using a typical Multimeter (supposing it can measure Current, apart from Voltage, both in AC and DC) ? ] (]) 05:42, 9 July 2016 (UTC)

:Not with one measurement. You need to measure the current, disconnect the multimeter, reconnect the supply, then measure the voltage. ] (]) 09:29, 9 July 2016 (UTC)
:Incidentally, if you have a simple arrangement with a resistor in series with the LED, you can measure the current by measuring the voltage across the resistor, and using the equation <math>I = {V \over R}</math>. You still need to make a second measurement of the voltage across the LED, though. ] (]) 09:41, 9 July 2016 (UTC)

::Many thanks Tevildo. If it's not taking too much advantage of your generosity, I'd beg you to be a bit more elaborate. For instance in first instruction you say "measure the current", now shall I measure it along with LED attached or LED removed from the circuit. And is it true that current is never measured like voltage (in parallel) but in series ? As for putting resistor in series with LED that ain't difficult, why not simply jump to this step ? Please tell how voltage across resistor and across LED ultimately give us wattage. Unless I am very much wrong I think current and wattage are separate things. ] (]) 17:00, 9 July 2016 (UTC)

:::No problem, it's what we're here for. I'm assuming your circuit is basically the same as the one to the right (from our ] article, with annotations). To find the power, we need to find the voltage across the LED and the current through it, and multiply them together.
:::Measuring the voltage across the LED is easy:
:::*Set your multimeter to "DC Volts".
:::*Connect the positive lead to point B on the diagram, and the negative lead to point C.
:::*The reading on the multimeter is the voltage across the LED. Let's call this <math>V_{LED}</math>. For example, it might be 3&nbsp;volts.
:::There are two ways to measure the current. The first is to measure it directly with the multimeter:
:::*Disconnect the wire between the power source and the LED (between points A and B on the diagram).
:::*Set your multimeter to "DC Amps".
:::*Connect the multimeter positive lead to point A on the diagram (the supply positive output), and the negative lead to point B (the LED anode).
:::*The LED should now be on. The reading on the multimeter is the current in the LED. Let's call this <math>I</math>, as in the diagram.
:::The second way is to measure the voltage across the resistor. This assumes you know what its resistance is.
:::*The circuit should be connected as in the diagram (with the LED on).
:::*Set the multimeter to "DC Volts".
:::*Connect the positive lead to point C, and the negative lead to point D.
:::*The reading on the multimeter is the voltage across the resistor. Let's call this <math>V_R</math>.
:::*If the resistance of the resistor is <math>R</math>, the current in the LED is <math>V_R \over R</math>. For example, if <math>R</math> is 100&nbsp;ohms, and <math>V_R</math> is 2&nbsp;volts, the current (<math>I</math>) is 20&nbsp;mA (0.02 = 2 / 100).
:::Now we know <math>V_{LED}</math> and <math>I</math>, the power of the LED (in watts) is <math>W = I \times V_{LED}</math>. Using the numbers from above, the power is 20&nbsp;mA * 3&nbsp;V = 60&nbsp;mW. Hope this helps! ] (]) 18:08, 9 July 2016 (UTC)

== File disambiguators (1): Explorer/W11 ==
:::To be more specific, if you try to measure the ]s of an ] circuit by measuring ]s and ]s separately and calculating the result, you end up with ]s, not watts. In ] circuits watts and volt-amperes are identical, so the technique works. The math is easy: volts times amperes equals watts, as Tevildo explained in detail above. --] (]) 22:09, 9 July 2016 (UTC)


Óla! So Explorer adds (''n'') to a file with a duplicate name to an existing one. Do you have suggestions how to easily identify and delete them? The search option doesn't recognize parentheses, so a search would merely identify files with that number in the title. The reason for asking is that if a folder has a large number of duplicates that should be deleted, it would be easier to sort/select/delete rather than ctrl+click individually.

::::Thanks for reply, Hans. If you don't mind, I'd like to know what is meant by "connected to ground" ? And how does it disqualify an oscilloscope from correct and safe gauging. I think doesn't that simply mean that like many other electric appliances that run on A.C. mains, it has its outer metallic body attached to a ''3rd wire'' that takes back any leaked current, through a cable common to whole house or complex, back to be sunk into the ground through a conductor buried considerably deep into it ? - O.P. <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding ] comment added by ] (]) 04:58, 13 July 2016 (UTC)</small> <!--Autosigned by SineBot-->


== Selecting multiple items in checkbox on this website. Is there an easier way? ==
:::::Unlike a portable multimeter that has two uncommitted probes (red +ve and black -ve), oscilloscope inputs are usually coaxial with the outer (shield or screen) permanently connected to the case and ground. If the LED circuit under investigation is powered by battery or some other floating power supply there is no problem. However if the LED circuit is part of mains-powered equipment whose circuit is connected to ground, the extra route to ground through the oscilloscope may cause a damaging short circuit. Some two-channel oscilloscopes offer a differential measurement mode that overcomes this limitation. It is also possible to "float" an oscilloscope without its ground connection but that strategy is risky even in the hands of experienced professionals. ] (]) 10:58, 13 July 2016 (UTC)

== Airlines use of continuous stationary ==


On the left of the web page you will see a checkbox "Status" with 3 items checked. The problem I have is that the only way I can get multiple items checked is by '''editing the URL'''. If I just click on an item in a checkbox on this website the other items get unchecked. In other words: the checkbox works like radio buttons. I tried a different browser; I tried ctrl-click and shift-click and alt-click. Nope. On other websites ( for example) I do not have this problem. Do you experience the same inconvenience? And if so any ideas on how to do this easier than by url editing? ] (]) 11:55, 30 December 2024 (UTC)

:::One obvious factor is cost. The best technology to replace these old technologies, as far as readability, is likely a black-and-white ] (color seems like an unnecessary expense). I imagine they cost more initially (but maybe not by much, if it only prints the width of a receipt or airline ticket). However, for these high volume operations, the more important issue is what it costs per print.

As to the use of thermal printers, they're very quick, but a key advantage may be that there's only one consumable (a thermal roll) rather than paper/ribbon or paper/ink or paper/toner - relatively speaking, this makes them a very much more easy to maintain than a printer which requires both. --] ] 22:34, 10 July 2016 (UTC)

::::re {{U|StuRat}}s' query about ''Thermal Printers'', I agree the big advantage of thermal printers may be speed.

I have worked a lot (in the past) with inkjet log printers, and I was surprised that in this application were practically instant, i.e you tap the touchscreen asking for a 'receipt' and ''bang'' its there. Barely get the chance to lift my finger off the screen. Agree with {{U|Tagishsimon}}, in other words.

::Airlines were among the earliest ]. It's entirely possible that some of what we see today just comes from the old adage of "if it ain't broke, don't fix it".

:::In other words, you have a list of at most ''n'' lists of integers, the integers themselves ranging from 1 to ''n'', the lists of integers presumably unsorted, with the additional constraints that the individual lists of integers have no duplication and that no two lists of integers from your list of lists would be the same even if sorted, and you want an efficient way to merge this list of lists into a single list containing, without duplication, exactly those integers which appeared in any list of your list of lists.

Theoretically if Microsoft had continued to develop and invest in the DOS-based Win9x line instead of switching to NT, could they have produced a 64-bit OS running on-top of DOS that took full advantage of modern hardware capabilities? <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding ] comment added by ] (]) 14:39, 13 July 2016 (UTC)</small> <!--Autosigned by SineBot-->

:There is no reason that DOS couldn't be altered and compiled to take advantage of a 64-bit CPU. Keep in mind that jumping to 64-bits isn't always an advantage in every single possible application. So, playing an old DOS game in 64-bit DOS won't make it better. ] (]) 16:06, 13 July 2016 (UTC)

== What happens exactly when you clone your SIM card ==

If you clone your SIM card and use both the new and old card at the same time, how will the phone company react? How will they discover it? Is there a central server with a list of all numbers and where they are? What if one card accesses the network through roaming? ] (]) 16:21, 13 July 2016 (UTC)

:Yes, they do keep a database, See ], ], and ]. There are special clone SIMs that disables the first SIM when switched on, but as far as I know the carrier has to turn on support for such devices.

== Spy potential of Pokemon Go ==

I've been seeing a wave of newsvertisements for ] that is unrivalled since, well, Facebook Live's snuff video PR campaign, including inducing players to jump a fence to find a dead body, and it's left me thinking about how useful this app may or may not be to spy agencies, police, or even ordinary private dicks.

* Who is in charge of placing the Pokemon monsters or other targets? Is there a straightforward way for a third party to set up an attractive feature on some property they want inspected?

* How do players find the targets they are looking for? Is there a general 'directory' that leads them to the land they are supposed to reconnoiter?

* Is the game known to ''upload'' the video the phone is taking in order to put the cartoon figure on the screen, or is that done locally?

* Does the game have a way of collecting data about things in the area, e.g. other cell-phones, Wi-Fi identifying numbers, etc.?

* If a player trespasses in order to happen across evidence, is there any possible legal argument that he is a "police agent" if it could be shown that police put the target on his map, or does his personal decision to trespass to play the game put an end to any attempt to claim a warrantless search?

* I've read about players being lured to police stations to hunt Pokemon, with cops complaining about it; is there any way to lure a ''particular'' player to a police station without luring all of them, say if that particular one had outstanding warrants?

* Are players being lured near crack houses and other highly hazardous features that someone might want to have periodic video surveillance of? I didn't see this one but it seems like an understandable "accident" to have happen.

Is this bug in the google search ?

I searched for the keywords: "Israel Folau" "Margaret Court" "David Tyree", then Google shows me blank. Is this bug?HarryOrange (talk) 22:35, 24 December 2024 (UTC)

If I do the same search, this question shows up (twice, due to how the refdesk is organized) plus a link to Stuff. So, it doesn't seem to be a bug. I tried the same format search with much more famous people and got hundreds of links. Matt Deres (talk) 13:20, 25 December 2024 (UTC)
Remember that Google has numerous servers that can respond to your search, and they do not necessarily all behave the same. --142.112.149.206 (talk) 22:17, 27 December 2024 (UTC)

File disambiguators (1): Explorer/W11

Óla! So Explorer adds (n) to a file with a duplicate name to an existing one. Do you have suggestions how to easily identify and delete them? The search option doesn't recognize parentheses, so a search would merely identify files with that number in the title. The reason for asking is that if a folder has a large number of duplicates that should be deleted, it would be easier to sort/select/delete rather than ctrl+click individually. Thank you! 2.28.124.91 (talk) 16:31, 28 December 2024 (UTC)

Thank you Polygnotus, that's great, and freeware too. It looks like it might take some getting used to! Cheers, 2.28.124.91 (talk) 18:13, 28 December 2024 (UTC)
Use a better search program - FileLocator will find * - Copy (*).*, and I'm sure there are others with will also do the job.
Use the command prompt, eg dir "* - Copy (*).*" works. (You can also use del similarly, but do so with caution and at your own risk.)

Selecting multiple items in checkbox on this website. Is there an easier way?

Please look at this link:

https://www.archonia.com/en-us/search?q-a2%5B0%5D=1&q-a2%5B1%5D=2&q-a2%5B2%5D=3&qf%5B0%5D=3046&filter_string=doctor%20who

On the left of the web page you will see a checkbox "Status" with 3 items checked. The problem I have is that the only way I can get multiple items checked is by editing the URL. If I just click on an item in a checkbox on this website the other items get unchecked. In other words: the checkbox works like radio buttons. I tried a different browser; I tried ctrl-click and shift-click and alt-click. Nope. On other websites (here for example) I do not have this problem. Do you experience the same inconvenience? And if so any ideas on how to do this easier than by url editing? 213.126.69.28 (talk) 11:55, 30 December 2024 (UTC)

Not necessarily AFAIK, and that's coming from someone with experience in web design. You're unfortunately seeing their poor web design. TheTechie@enwiki (she/they | talk) 00:17, 31 December 2024 (UTC)

Windows 10 Bin

Doing a quick search online I realized that the path to the Windows recycle bin is C:\$Recycle.Bin; however, for some reason I don't understand, it doesn't seem to be the "Recycle Bin" on the desktop, they just seem to be two different paths (explanatory screenshot at the following link: ). Are they actually two different paths? If so, why? If not... why aren't the two windows synchronized? 2A01:827:160:D601:2E75:E3BA:BBBF:B55D (talk) 14:35, 30 December 2024 (UTC)

Question(s) about Arch Linux

Moved from User talk:TheTechie § Aaaaarrrrchh brrr!

@TheTechie ... A question? Do you used archinstall to install Arch Linux? I think i will install Arch Linux, cause, i want BTW Vitorperrut555 (talk) 23:31, 1 January 2025 (UTC)

Moved this here as I found this to be a better place for it. As for your question, no, I used text commands. Though I may be able to help. Any specific questions? TheTechie@enwiki (she/they | talk) 00:32, 2 January 2025 (UTC)
@Vitorperrut555 TheTechie@enwiki (she/they | talk) 00:41, 2 January 2025 (UTC)
When I installed Arch Linux, I used a live-boot USB. Once booted, it has an "install" icon that can be used to do a basic install. Then, once installed, you can customize it by removing and adding the packages you like. 68.187.174.155 (talk) 15:42, 2 January 2025 (UTC)
68.187.174.155, I think you're confused. Archinstall is a command on Arch Linux, and the Arch Installer boots in text mode. You may be thinking of an Arch derivative like Manjaro or EndeavourOS, which do indeed boot up in graphical environments. TheTechie@enwiki (she/they | talk) 20:23, 2 January 2025 (UTC)

Bayeux Tapestry website

What image-serving technology is the new Bayeux Tapestry website using, and how can high-res images be downloaded? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 20:59, 2 January 2025 (UTC)

@Pigsonthewing Welcome to the Reference Desk for Computing. Are you trying to download all images, or only specific ones? If you reply here, please ping me. Thanks, TheTechie@enwiki (she/they | talk) 00:54, 3 January 2025 (UTC)
The former preferably, but an answer for either would be of interest, as the technology is likely in use elsewhere. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 16:46, 3 January 2025 (UTC)
According to their terms of use, "Access to this panorama is free for a private or public non-commercial use. Any commercial use of this tool is prohibited, as well as the extraction of images from this panorama" (my emphasis). This may or may not bother you. Chuntuk (talk) 18:24, 3 January 2025 (UTC)
Even more, the "images" which get loaded are tiled portions of the actual image. TheTechie@enwiki (she/they | talk) 19:11, 3 January 2025 (UTC)
