== Is anyone here a Reddit moderator or do any of you know well why the automod is glitching out badly on me? It keeps autoremoving my innocent posts no matter what subreddits I post in. == |

I was highly displeased at all the flame I got for my last post, now my question is what are the antivirus programs that come with lets say a mac laptop or a pc from either 6 years ago or now. I'm not talking about program trials either, my cousin just got a new mac and want to know if he's properly protected by built in antivirus programs if any. Thanks in advance.

:General information: Most PCs come with only trial subscriptions to antivirus programs (6 months or so), and Macs come with no antivirus software at all.

Thank you for the answer, so from what I got your answer is that the majority of pc's don't have any permanent antivirus programs at all???

::Unless the particulars of the deal included the vendor installing a full version of some anti-virus program, your cousin's Mac doesn't have any anti-virus software on it. They don't come with any from Apple. That said, in the 18 years that I've been using Macs, I've never once had a virus or other malicious program on my systems. Partially because there are significantly fewer viruses written for Macs as well as the fact that I'm careful about where I go on the net and what I click on. It's not that Macs are badly protected when sold it's that, for the most part, it's just not necessary. It's like someone who lives in the United States getting a malaria shot.

::Windows Vista comes with [[Windows Defender]]. [[Mac OS 10.6]] (released in 2009) also comes with a hidden anti-virus program. All versions of Windows also automatically download the [[Windows Malicious Software Removal Tool]].

:::That basic protection, though, is very limited. The Windows MSRT only scans for specific prevalent families of malware once a month, so it cannot prevent infection by malware. The Mac OS X 10.6 "file quarantine" only applies to files downloaded using Safari, iChat, ''etc.'' and only scans for a small set of Mac [[trojan horse program]]s. It won't prevent the user, for example, from spreading a Windows virus or [[macro virus]], or spreading a virus via [[flash drive]] (if a Mac virus were to spread that way).

Thanks for all the answers, I really appreciate it. Over the past two days I've been testing to see if a keylogger would be blocked by a number of computers. What I found out was very similar to your answers. It was detected on 3 out of the 5 computers with just built in antivirus, the keylogger was'nt detected on a mac and another pc.

:Sorting by size would make it easier. If two images look the same but have different file sizes, there's probably a difference in quality or a filter has been applied, and you probably want to take a closer look to determine which is worth backing up.-[[User:Gadfium|Gadfium]] ([[User talk:Gadfium|talk]]) 21:36, 30 November 2024 (UTC) |
|||
::Using a compressed image format like jpeg, it's indeed very unlikely that two different images have the same file size, but if there are thousands of images of a few megabytes each, you'll probably have some collisions. See [[birthday problem]]. Also, two identical images may still have different file size if there's a difference in their metadata. For example, one may have a caption added. Still, sorting by file size would be a good start. Only if you're dealing with a huge number of pictures it's worth finding a more advanced method.

:::I don't see any real reason to use something as crude as exact filesize instead of file contents i.e. hash or checksum which is almost as trivial for any duplicate detection tool and even on a USB flash drive shouldn't take that long. E.g. [//dupeguru.voltaicideas.net Dupeguru] definitely can and it sounds like [//github.com/qarmin/czkawka Czkawka] can as well although at least for Windows there must be thousands and even going by only free hundreds and I expect at least tens FLOSS. I mean you might occasionally have images which are basically duplicate but have some minor changes in the metadata or whatever which you'd miss by using contents, but it's still the better choice IMO. Dupeguru and Czkawka also have similar image functionality although I've never used such functionality since I've only ever been interested in removing exact dupes. This isn't a problem for images but if we're talking large files and you're concerned about time and you're fairly sure you don't have corruption etc, I think some tools allow only hashing a part of the file to speed things up. (OTOH, if you're worried about malicious damage/changes, make sure you choose a tool with a secure hash although this isn't a common concern.)

:What exactly is making it difficult? Is it because the duplicates could be in different folders? How exact a duplicate do the images have to be to be considered a duplicate? If everything is in one directory, sorting by filesize would work, as others have mentioned. If I was doing the task, I'd sort by size and switch the view to large thumbnails or whatever. If pictures are in ''multiple'' directories, things get more complicated. When I had a similar task to do, I actually made use of the command line's DIR function to get me a list of every file in every directory and import that into Excel where I could easily check for duplicate file names, file sizes, creation dates, and so on.

Hello! I'm developing a Java application that uses network sockets to transfer <code>Object</code>s between two computers over TCP though <code>ObjectInput/OutputStream</code>s. My problem is I can't figure out what's the best way to implement a lock for the socket's <code>Input-</code> and <code>OutputStream</code>s so that when one computer wants to transfer an <code>Object</code>, the other is listening. The easiest way seems to be use two sockets and two threads per computer (an up-down socket and a down-up socket, and a thread blocking to read or write on the designated side), but that sounds really inefficient (though I'm not that familiar with socket application, so if that's the way it's usually done, I wouldn't know). I've experimented with interrupting threads blocked in I/O operation for similar tasks in the past, and they seem to ignore the interruption. (It seems like the Java API specifies a different behavior with every subclass of <code>InputStream</code> for interrupts, which gets very confusing and difficult with sockets.) I'd appreciate any related information, especially specific to Java. Thank you!--[[User:El aprendelenguas|el '''Apre'''l]] (<sup>[[Special:Contributions/El aprendelenguas|facta]]</sup>-<sub>[[User talk:El aprendelenguas|facienda]]</sub>) 03:49, 27 August 2010 (UTC) |

:One socket is sufficient for bidirectional communication; you can "simultaneously" send and receive (on both ends). In other words, both ends of the socket [http://download.oracle.com/javase/1.4.2/docs/enwiki/api/java/net/Socket.html implement] an InputStream and OutputStream. Writing to the output streams, as defined in the java.io interface, is ''non-blocking'' - so you can write data, and it will get buffered on the other end until the other program is ready to read. When reading, just be sure to check if bytes are available, and only read that many (guaranteeing that you won't block indefinitely); or set up a read-timeout or channel for non-blocking reads. The Java socket API abstracts this for you; you don't have to worry about locking the ''socket'' for [[full duplex|bidirectional communication]] to work. (Whether the data is actually flowing both directions ''simultaneously'' is entirely dependent on your network card driver; if it doesn't support this, the JVM or the operating system will buffer and serialize the datastreams; [[Transmission control protocol|TCP]] sockets ''guarantee'' that data will never be lost because of such buffering at any point in the network). In terms of ''efficiency'' - well, if you're sending and receiving, you're increasing your network traffic - so if your hardware is maxxing out on bandwidth, you'll be able to measure the slow-down; but it will only affect ''performance'', not ''functionality''. If you implement multiple sockets, (and your hardware and operating system support it), each socket could map to a different IP and network interface, parallelizing the data flow, so that could conceivably benefit you; but only if you actually have multiple IPs and network cards per machine.

::Thank you for the rapid (less than 10 minutes!) and informative reply, Nimur. I didn't know that sockets supported two-way communication—it sure makes a lot of things easier! Your note about checking available bytes before reading them was also helpful, as it led me to check the documentation for <code>ObjectInputStream</code>'s constructor, which blocks and was part of my problem.

:::I haven't done any Java socket programming, but <tt>OutputStream.write</tt> ''must'' block because the alternative is too horrible to contemplate. Writes to a TCP stream have to block when the write buffer fills just as reads block when the read buffer empties. If the write buffer were allowed to grow indefinitely, you could exhaust all available memory by sending a 10GB file on a socket at 30MB/s when the recipient happens to be on a 1MB/s DSL line. |

== Does the [[Reddit]] Automod know that I access an account on [[DuckDuckGo]]? == |
|||
:::If I understand correctly, you want each computer (call them A and B) to act as an object server for the other. Abstractly, you have four unidirectional message types: requests A→B, responses B→A, requests B→A, and responses A→B. Your original idea of two TCP connections gives you four unidirectional streams, one for each of the message types. Nimur's suggestion is to use one TCP connection and multiplex requests and responses onto the same stream. That would be somewhat harder to implement and I'm not sure if you'd see a performance benefit. If you processed each stream sequentially, you could see a degradation in performance, since a request from B to A couldn't go through while a request from A to B was pending. |
|||
Is a connection to Reddit via DuckDuckGo pretty [[sus]] to the Automod? Is it why the automod has been autoremoving all of my legit posts? |
|||
:::You also need to think about deadlock. Is it possible that satisfying the other machine's request for an object will require requesting an object from the other machine? If so, consider what happens if B requests X from A and, to satisfy that request, A needs Y from B. If you're using a single TCP connection and everything is sequential, you're doomed at this point, because the request for Y can't go down the wire until X has been sent. If you use two TCP connections, you're okay in that case, but then consider the possibility that B needs X' from A in order to satisfy the request for Y.

::::Thank you for your concerns.

:Reddit automods produce a reason why posts are removed. You haven't provided us with the reason the posts were removed. If you don't know, you need to look at the change update and instead of quickly deleting it or clicking 'read' on it, read it. I have never ever seen any hint of any automod that looks to see if the user is using a DuckDuckGo web browser. It is far more likely that you are posting something that is not allowed and the automod is removing it and you are not reading the reason why it was removed. It can be trivial. For example, I asked a question on one Reddit page and it was immediately removed. The reason for removal explained that a different Reddit page was the correct place to ask the question, so I asked it there instead and it wasn't removed.

:::::'Sequentially' in this case means that if A requests an object, it cannot make another request until B has responded with said object, and vice versa. It's essentially a 'conversation': one speaker at a time, and with one TCP connection you are limited to this. It can decrease performance, if a long response or network latency blocks the connection when a new request needs to be made. If you go for an implementation with two connections, both computers can send requests whenever they need to. The two separate connections aren't automatically synchronized in any way, which might cause other design problems. I hope this helps.

:Presumably the window has a maximized state and you're switching to that state. Perhaps your mouse movement is being misunderstood as a touchscreen swiping gesture, if such a maximize gesture exists on the OS, and perhaps you can switch gestures off in the settings. Another possibility is that your mouse has a fault (low battery or a broken button) and is sending double-click messages sometimes, making the window maximize in response to a double-click on its title bar, if ''those'' are understood by the OS as maximize. Do you find the title bar slips from your grasp sometimes, as well? That would imply a mouse hardware fault.

:The keyword in [[AJAX]] is ''asynchronous'' - so yes, you can ''definitely'' have multiple independent queries in-flight at any time, going to the same or different programs on the server-side. (This is the whole point of AJAX!) If it isn't working, it may be some kind of a bug in the order that data is returning ("asynchronous" of course means that there's no guarantee on timing or re-ordering of queries - your server could be doing "smart" things at the HTTP layer, etc.). Have you considered wrapping your data and responses in [[JSON]] (a very lightweight and simple text-based data object format)? Then, you can easily tag every transaction with its source program (A or B) and some kind of unique transaction ID to ensure it's processed in the correct place / order. This will make it easier to parse your queries and responses and guarantee that data goes where you intended (to the right server-side program / client-side javascript function, and so on).

:HTTP/1.1 specifies a connection limit of 2 connections per server. Although browsers recently started increasing this limit for better Ajax responsiveness, you might still run into this depending on what else your application/other tabs are doing. Other than that, multiple XMLHttpRequest objects shouldn't be a problem, and then I'd suspect that somehow your completion handler for B is interfering with the xhr object for A. Do you reuse A and B's XHR object, or create a new one for every request?

::Number of connections per server can be set by the server configuration; but that's something to check. On reading Steve's code a bit more carefully, I wonder if he's using the same variable name (xmlhttp) for ''both transactions''. This is one of those things that you know not to do in C++. But Javascript makes this problem even more acute, because [http://www.digital-web.com/articles/scope_in_javascript/ scope in Javascript is so complex]. You can almost always assume that "it's a global variable." I would check closely: are you ''over-riding'' Transaction A 's registered callback by assiging xmlhttp.onreadystatechange during the initiation of Transaction B? ''You're probably mucking with the first transaction object!'' In other words, Transaction B isn't a new instance of xmlhttp: it's ''the same object''! Check carefully; for safety, use clean, new names for each object; and if that fixes it, good. Follow-up by with some web-searches on "scope in Javascript" - this is a ''very'' common programmer-error because JS is so different from normal languages, it's almost impossible to have a "locally-scoped" variable.

:::Number of connections is a client-side restriction too (and there is no standard way for the server to communicate a limit, expect by using HTTP/1.0 instead of /1.1) and requires a configuration change to modify, see eg here where [http://support.microsoft.com/kb/282402 IE7 defaults to 2 and requires a registry change]. JavaScript local variables work fine, as long as you properly use the var keyword or put them in objects, and realise that even 'var' variables in JavaScript have function-scope, not block-scope as they would in most other languages.

:<drumroll>...and the winner is...Nimur! Yes, I had goofed up the scope of my XMLHttpRequest and was using the same object for both transactions. (I really, deeply, truly **HATE** JavaScript!) Giving each request a different name fixed the problem. Many thanks folks! |
|||
:@Unilynx: Now you have me worried about the transaction limits! I expect to have 50+ people using this site at the same time - and that means that there will typically be 50 connections to program A - all waiting for their 8 second heartbeat - plus some random number of connections to program B...so there could easily be 50 connections to the server - and perhaps as many as 100. When you say "a connection limit of 2 connections per server" - I hope you mean "two connections TO EACH CLIENT per server" or something - not a total system limit of two connections...right? |

== Nuclear Physics-Package Simulation Software == |
|||
<p>Hi.</p> |
|||
<p> I am seeking simulation-software which can be used to simulate the deformation and detonation of nuclear physics-packages. It should be able to:</p> |
|||
#Accept input of shape, size, dimensions, mass, etc. of the fissile core, neutron reflector, explosive lenses and package-wall. |
|||
#Visually simulate deformation of all parts of the physics-package (fissile core, neutron reflector, explosive lenses and package-wall) upon detonation. |
|||
#Output numerical values for the following at the moment of detonation; |
|||
##tonnage (TNT equivalent), |
|||
##nett energy release (in newtons), |
|||
##nett force (in Pascals) at various distances from the epicenter, |
|||
##temperature (in either kelvin or celsius) at various distances from the epicenter, |
|||
##and percentage of fissile material wasted (i.e. which did not undergo fission). |
|||
#Support designing with the following materials: |
|||
##Fissile Material: Uranium, Plutonium, Americium, Curium, Californium, Protactinium & Radium. |
|||
##Neutron-reflector: Beryllium, Titanium, Tungsten, Osmium, Steel, Graphite, Gold, Lead & Uranium. |
|||
##Explosive Lenses: Trnitrotoluene, Cyclotrimethylenetrinitramine, Cyclotetramethylenetrinitramine, Octanitrocubane, etc. |
|||
##Package-Wall: Titanium, Tungsten, Duralumin, Iron, Steel, Carbon, etc. |
|||
<p> Does anyone here know of any simulation-software (preferably free and/or open-source, but commercial is also acceptable) which meets these criterion? Any information or pointers would be useful. The available computational power for running this software would be about 2.06 teraflops. Thank you to everyone.

:I would strongly suspect that software packages with the level of detail you describe are mostly or entirely the property of national governments and classified as state secrets. If you are employed by such a government, then you might get access to their software. Otherwise, you'd probably have to develop your own software. I suspect that one could probably find public information on things like models of various explosives, or neutron response curves for various materials. However, the data to comprehensively validate a nuclear detonation model is probably also a state secret since only governments have ever been able to test bombs.

::The hard part is not ''simulating'', it is ''simulating accurately.'' For example, [[AutoCAD]] and several of its commercial and 3rd-party plugins can do deformation finite-element modeling. And if you home-brew your own full-fledged CAD tool and numerical modeling software, you can do your best to estimate all the necessary parameters, and visualize the output however you like. But do the equations used to estimate the dynamics and the material properties apply to the unique situation of nuclear detonation? The only way you can know this is if you have access to ''both'' the software (and all the mathematics behind it) AND access to empirical nuclear test data. As you know (if you use or design CAD tools), accurate [[equations of state]] suitable for predicting and modeling are ''very complicated'' and are rarely developed from [[first principles]] of physics. They are highly-parameterized and tuned for specific experimental conditions. Only a few places - say, [[Lawrence Livermore National Laboratory]] and [[Los Alamos National Laboratory]] will be able to have access to these sorts of parameters; and there is an entire ''profession'' dedicated to the validation of nuclear weapons physics-packages through computational simulation. And, as Dragons Flight points out, because of the sensitive nature of nuclear weaponry, these sorts of career-tracks invariably require access to confidential and controlled information. Your best chance to get such software is: |
|||
::#Begin the long and arduous process of studying an advanced technical field, like computer science, mathematics, physics, or nuclear engineering |

== What is 32kb of "used space" on an empty USB pendrive? == |
|||
I've plugged an empty USB2 pendrive into my computer. I had previously deleted everything on it and reformated. But when looking at the properties of the drive in WinXp, it shows 32kb as "used space". What is this "used space" used for? Could anything sinister be lurking there? Thanks [[Special:Contributions/92.15.21.39|92.15.21.39]] ([[User talk:92.15.21.39|talk]]) 19:31, 27 August 2010 (UTC) |
|||
it will be the space containing information about the drive. I can't think of the name for it (like the 'reserved' space on a cd) but someone will fill you in on the blanks. There's a certain amount of space lost between the advertised size and the size itself (though this is slightly different to that I believe).

:* It could be firmware used by the pendrive itself (which would be in hidden files so you can't delete them) - I had a pendrive with an LCD display on it that had a startup Logo that was stored as a file on the drive itself that you couldn't erase or overwrite no matter what. |
|||
:* It could be directory space and free space map for a FAT filesystem (this is by far the most likely thing). |
|||
:* It could (maybe) be bad "sectors" that it's mapped to prevent you from using them. Flash memory does eventually 'wear out' and stop working - and fancy flashdrives know to 'lock out' that worn out space so you don't use it again and corrupt a file. Cheap flashdrives don't do that (at least, not that I've noticed). |
|||
:OTOH, I don't think it's a difference between advertised space and real space as Ny156uk suggets. (eg hard drive manufacturers quote "Megabytes" meaning 1,000,000 bytes and not 1024x1024=1,048,576 bytes so it looks like they have more space than they really do). The reason I don't believe that is because the "used space" that WinXP measures will be in self-consistent units with "total space" and "free space" - there wouldn't be a discrepancy. However you might well seem to have less free space on the drive than it implies on it's case for those kinds of reasons. However, I don't think flash drive manufacturers do the god-awful things that hard drive vendors do. When they say "4Gb", they really do mean "4x1024x1024x1024" - minus the things I listed above.

::Actually flash memory device (cards, USB sticks and I think SSDs) manufacturers do use decimal based bytes.

::<s>Windows Explorer doesn't report the size of FAT16/FAT32 metadata ("directory space and free space map"), so it's not that, unless the volume is formatted as NTFS, in which case the used space would be much larger than 32K. 32K is too small for FAT as well except in unusual circumstances (a very small USB drive formatted as FAT16 might qualify).</s> USB flash drives manage bad sectors internally and don't report them to the OS (ditto modern hard drives), so it's not bad sectors. It can't be an undeletable firmware file because USB drives behave as block devices to the operating system; they can't control what the operating system does at the filesystem level. It's not a difference between advertised and actual size because drives just have one size; they don't know what it said on the retail box. |

== Can't log into facebook!! == |
|||
Ok, so here's what happened. I created my facebook acount in the united states, and I later moved to British Colombia in Canada. When I tried to log in, it said something like "your location is unfamiliar with this acount,yada,yada,yada...", so then Facebook made me do a little quiz, where I had to Identify pictures of people on my friends list. The problem is that I have over 450 friends on facebook, and I don't know who all of them are...in fact most of them are random ppl I've met on the internet. Now my question is "is there any way to bypass this, or at least to trick facebook into thinking I'm still in the united states??". Would masking my ip help???? If so how do you mask an ip address??? Any help would really be appreciated, since I really need to log in! Thanks in advance! [[User:Wikiholicforever|Wikiholicforever]] ([[User talk:Wikiholicforever|talk]]) 22:14, 27 August 2010 (UTC) |

If you go to ''Start --> Control Panel --> Internet Options --> Connections --> LAN Settings'' and check the box that says, "Use a proxy server..." you can enter in the IP address of the proxy. Then, Internet Explorer will connect to the Internet using that proxy.

== Flash video (in embedded player) restarting computer == |
|||
{{resolved}} |
|||
Hello, |
|||
I had something quite odd happen to me the other day: a Flash video in a player embedded on a web page (see link below) caused my computer to spontaneously restart (what Microsoft apparently refers to as a blue screen/stop error). Once Windows had started again, the "your system has recovered from a serious error" information box was displayed. No damage appeared to have been done, so I tried to watch the video again and the same thing happened again (at the same point in the video). |
|||
I've checked the integrity of my hard drive using [[CHKDSK]] and scanned for viruses using both [[Malwarebytes' Anti-Malware|MBAM]] and Symantec Antivirus and there don't seem to be any problems on either front. |
|||
I watched some other videos that use the same embedded player on the same site and they all played without incident. Today, my brother was watching a video on a completely different site that (as far as I can tell) uses a different embedded player and the same thing happened. In both cases, this was in Firefox (version 3.6.8). |
|||
So, does anyone have any idea what might be causing this? Could it be video card drivers? Firefox? Giant squirrels from the future? It's not really a major problem, but it's pretty strange. |
|||
'''Information''' |
|||
* First video that caused the problem: [http://www.tvo.org/TVOsites/WebObjects/TvoMicrosite.woa?civics101_explained#90604293001tvo "Everybody plays a part"] ([[TVOntario|TVO]] video that teaches kids about civics) |
|||
** Note that other videos on the same site did not trigger restarts |
|||
* Second video that exhibited the same problem: [http://www.comicbookresources.com/?page=article&id=28049 "Thor"] (the first video on the page, described as "Tom Hiddleston tells MTV News ...") |
|||
* Computer: Windows XP SP3, 2.4 Ghz Q6600, 2 GB RAM, ATI Radeon HD 5770 |
|||
* Browser: Firefox 3.6.8 |
|||
Any ideas about what's causing this would be appreciated - I'm pretty curious about how an embedded Flash video could trigger a system restart. |
|||
Thanks, |

This is related to the 2nd post up, not so much to the one right up. I followed the instructions in the first and installed download manager, put in my URL, etc. But the download manager keeps logging a "redirecting" and the files don't work. They are too small and when I try to open them in PDF Reader I get the message "Adobe reader could not open [filename.pdf] because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded". PS: This site requires a username/password so I gave the manager my username/password and checked the box and logged in; it still didn't work.

==DHCP irritations== |
|||
[Preamble: I made a confused question about this [[Wikipedia:Reference_desk/Archives/Computing/2010_August_10#LAN_authentication|back on 10 August]], then had to use a different place; now am back with a clearer head.] |
|||
There's an ethernet cable in my office. If it's plugged directly into my computer, then when I come in and first turn on the computer, start up a browser and attempt to go anywhere, I'm greeted by a page for DHCP that asks me for my ID and password -- and after I've typed both in correctly I stay connected all day, or at least until the computer falls asleep and is reawoken. By contrast, if the ethernet cable is instead plugged into a wireless hub (router?), and the hub in turn connected to my computer, then after just a few minutes regular browsing becomes impossible: I'm instead served with the log-in page and must again type in my ID and password, which gives me a few minutes, until I'm instead served with (etc etc). Of course the whole point of the wireless hub is wireless and/or a second computer; but for diagnostic purposes I only have ''one'' computer (and no printer, etc) connected, and by wire. I don't see why my choice among the output jacks should matter, but I've tried two: each has the same irritation. |

|||
:I think I remember this question. If it's what I remember, this is a lot of new information, and highlights perhaps some misunderstandings. It's a bit of a non-sequitur to say that you're "greeted by a page for DHCP". When you plug in to ''your'' computer, what's likely happening is your computer asks for an IP address, a DHCP server responds with one, and then web server sends you to a login page. When you authorize, it somehow authorizes you. |
|||
:The most interesting new issue is the "hub", which you acknowledge is probably not a hub. That's probably the case, as it's hard to inadvertently buy one these days.

I agree that if neither copy nor paste is working then there is a serious problem. You could try copying from command line, but this just uses the same subroutines as copy-paste and drag-drop, so if these have been compromised by a virus then it will not work.

== Excel Graph == |
|||
Hi. I'm having a (most likely, very basic) problem with graphing some data in Excel and wondered if someone could help. So I have the numbers 1, 2, ..., 20 in one column. I then generate the next column (which lists my x values) by multiplying all of these by 0.2, giving me 0.0, 0.2, 0.4, ..., 4.0. In the next three columns I have some data determined solely by the x appropriate x value being plugged into one of three equations (for those interested, I'm actually finding numerical solutions to a differential equation). I then want to plot the final three columns against my x values but every time I try to do this, without fail, the scale for the horizontal axis runs from 0 to 21 and I cannot fathom how to change it to run from 0 to 4. Any ideas? I'm running Excel 2004 for Mac if that helps.

:::No. All the excel options plot values against value index except for scatter which is the only one to plot values against value.

My computer screen is currently at 60 Hertz. It has the option to go to 75 Hertz. What's the difference? Might setting it higher make looking at the screen less headache inducing? [[Special:Contributions/82.44.54.25|82.44.54.25]] ([[User talk:82.44.54.25|talk]]) 20:57, 28 August 2010 (UTC) |

:::In CRTs the pixels decay in brightness until they're refreshed, so the refresh rate is the flicker rate. In LCDs they don't decay, so the refresh rate only affects how quickly the image shown on the screen can change. If an LCD is visibly flickering, it probably means the backlight is dying and changing the refresh rate won't help. If your display isn't visibly flickering but you're getting headaches looking at it, you might want to consult a doctor. -- [[User:BenRG|BenRG]] ([[User talk:BenRG|talk]]) 02:04, 29 August 2010 (UTC) |

== Firewalled download == |

My connection to the internet is through a firewall. Whenever I try to download some big files ~50 MB, I get an error stating that the response to the HTTP GET request is above the limit. My guess is that the firewall's checking the file size from the response to the get and then disallowing the download. If that's the case, is it possible to circumvent the check ?

== Dissolving Exclamation Point == |

In the Finder Window on my Mac there is a different icon than there has been in the past next to my External Drive on the side under devices. Last week it was a partially dissolved exclamation point and now it is an almost completely dissolved exclamation point with a red octagon as a background. While this does worry me, the drive it self is working fine, able to save, copy, compress, and paste files with the same ease as in the past. Can anyone give me some insight? Thanks!

Anyway, I actually got into a chat room and it was working, but the name I was logged in under, automatically, was the name I assigned to my computer, which contains parts of my real name. I want to choose a different login name and not have my real name displayed.

::Thanks that works. However, it doesn't solve my issue. Once I join a chat room, I then change my name and have a new chat name. However, as far as I can tell when I do that displayed for everyone is the change from the old to the new. In other words, everyone sees my real name, and then they see something like "john doe has changed his name and is now logged in as jake doe".

[edit]Is anyone here a Reddit moderator or do any of you know well why the automod is glitching out badly on me? It keeps autoremoving my innocent posts no matter what subreddits I post in.
[edit]Please check out my account; what is it about my account that causes the automod to malfunction and keep autoremoving my posts?: https://www.reddit.com/user/AWrride/
My post karma is in the thousands and comment karma is in the hundreds so they're not getting removed for low karma, so why are they getting removed then? How do I stop getting bothered by the automod like this?
Also, most pleas in the subreddits' ModMails go unanswered. It's as if the mods don't read my pleas.
So could someone here please help me resolve the glitching automod problem so that I can get their automoderator to please leave me alone? Thanks. --2600:100A:B030:9399:A4B7:A7C4:A534:6D53 (talk) 17:36, 26 November 2024 (UTC)
- Automod is controlled by the moderators of the subreddit for each one, and is not something users can control. Sorry about it.
- Take my honest suggestion though: It might be a good idea to abandon the subreddit if this keeps happening. TheTechie@enwiki (she/they | talk) 04:06, 3 December 2024 (UTC)

[edit]Linking several WhatsApp numbers to a Facebook business account.
[edit]It is possible to link several WhatsApp phone numbers to a Facebook business account. One of them has to be set as the primary number: It will be contacted when someone writes a WhatsApp message to the business account. But what is the use of the other linked WhatsApp numbers? Do they just serve as spares, or do they have an actual, immediate use? --KnightMove (talk) 13:40, 28 November 2024 (UTC)
- Most commonly, they are used for different departments, different countries/target markets, or for specific campaigns being run by the company. "One of them has to be set as the primary number". Not really. One can be listed as the primary PER Facebook page, but a business account can have hundreds of FB pages (and instagram accounts, and as you noticed WhatsApp numbers). —TheDJ (talk • contribs) 21:37, 28 November 2024 (UTC)
- Ok, thanks. But we agree that one needs to be set as the primary number per page, and others can still be linked to that same page. Do they play any active role? If yes, which one? --KnightMove (talk) 09:07, 29 November 2024 (UTC)

[edit]Search by image on a USB flash drive
[edit]Is there a way to search for repeating (identical) images on a USB flash drive in Windows 10? Checking by eye becomes tedious for me, as I'm back-uping many of them and don't want to transfer identical jpg images with different file names. Brandmeistertalk 20:52, 30 November 2024 (UTC)
- Sorting by size would make it easier. If two images look the same but have different file sizes, there's probably a difference in quality or a filter has been applied, and you probably want to take a closer look to determine which is worth backing up.-Gadfium (talk) 21:36, 30 November 2024 (UTC)
- Using a compressed image format like jpeg, it's indeed very unlikely that two different images have the same file size, but if there are thousands of images of a few megabytes each, you'll probably have some collisions. See birthday problem. Also, two identical images may still have different file size if there's a difference in their metadata. For example, one may have a caption added. Still, sorting by file size would be a good start. Only if you're dealing with a huge number of pictures it's worth finding a more advanced method. PiusImpavidus (talk) 09:27, 1 December 2024 (UTC)
- I don't see any real reason to use something as crude as exact filesize instead of file contents i.e. hash or checksum which is almost as trivial for any duplicate detection tool and even on a USB flash drive shouldn't take that long. E.g. Dupeguru definitely can and it sounds like Czkawka can as well although at least for Windows there must be thousands and even going by only free hundreds and I expect at least tens FLOSS. I mean you might occasionally have images which are basically duplicate but have some minor changes in the metadata or whatever which you'd miss by using contents, but it's still the better choice IMO. Dupeguru and Czkawka also have similar image functionality although I've never used such functionality since I've only ever been interested in removing exact dupes. This isn't a problem for images but if we're talking large files and you're concerned about time and you're fairly sure you don't have corruption etc, I think some tools allow only hashing a part of the file to speed things up. (OTOH, if you're worried about malicious damage/changes, make sure you choose a tool with a secure hash although this isn't a common concern.) Nil Einne (talk) 14:53, 1 December 2024 (UTC)

- What exactly is making it difficult? Is it because the duplicates could be in different folders? How exact a duplicate do the images have to be to be considered a duplicate? If everything is in one directory, sorting by filesize would work, as others have mentioned. If I was doing the task, I'd sort by size and switch the view to large thumbnails or whatever. If pictures are in multiple directories, things get more complicated. When I had a similar task to do, I actually made use of the command line's DIR function to get me a list of every file in every directory and import that into Excel where I could easily check for duplicate file names, file sizes, creation dates, and so on.

[edit]Does the Reddit Automod know that I access an account on DuckDuckGo?
[edit]Is a connection to Reddit via DuckDuckGo pretty sus to the Automod? Is it why the automod has been autoremoving all of my legit posts?
What are other users' experiences like using a Reddit account on DuckDuckGo? --2600:8803:1D13:7100:BBC6:2B3:625A:265B (talk) 12:23, 1 December 2024 (UTC)
- Reddit automods produce a reason why posts are removed. You haven't provided us with the reason the posts were removed. If you don't know, you need to look at the change update and instead of quickly deleting it or clicking 'read' on it, read it. I have never ever seen any hint of any automod that looks to see if the user is using a DuckDuckGo web browser. It is far more likely that you are posting something that is not allowed and the automod is removing it and you are not reading the reason why it was removed. It can be trivial. For example, I asked a question on one Reddit page and it was immediately removed. The reason for removal explained that a different Reddit page was the correct place to ask the question, so I asked it there instead and it wasn't removed. 12.116.29.106 (talk) 15:25, 3 December 2024 (UTC)

[edit]Do any dashcams exist that livestream drives onto Twitch, YouTube and other livestream video apps?
[edit]As a Dasher for Doordash, I'd like to have strangers watch me drive deliveries live in real-time. I wonder about whether there's a Dashcam around that allows livestreaming onto any site / apps that allow users to watch anyone's livestreams. I would also like to make some of the obscure music that I play through my car's Bluetooth speakers known to the wider world.
If there isn't such a thing as a livestreaming dashcam, how come and what would it take to innovate a fully-working livestreaming dashcam in the first place? --2600:8803:1D13:7100:B55B:B71:F6ED:7780 (talk) 12:40, 6 December 2024 (UTC)
- If you have a phone or something you could probably try to figure something out by taping it with the camera looking out and then starting a livestream. I’m not too sure about any actual dash cams so I would wait for another user to respond 1250metersdeep (talk) 13:53, 6 December 2024 (UTC)
- You can use one of many streaming cams. You would have to use your phone (or similar device) as a mobile hotspot, tethering the cam to the phone for internet access. This assumes you have unlimited data on your phone. The headache will be that the cam will likely lose internet connection every time you leave the car to make a delivery. If it is a good cam, it will re-attach itself automatically and begin streaming again. 68.187.174.155 (talk) 17:14, 6 December 2024 (UTC)
- If you're not already aware, the sort of thing you're looking to do is often referred to as IRL (in real life) streaming and those who do IRL streams often use a collection of gear consolidated in the form of a backpack for easy wearability and transport. In looking for how to accomplish your specific goals I'd look into researching the backpack setups people have posted in various places. Amstrad00 (talk) 17:44, 6 December 2024 (UTC)
- I suggest also that you consider the copyright and licencing implications of re-broadcasting other people's music, and how any intentions to monetise your streaming (or not) might interact with them {The poster formerly known as 87.81.230.195} 94.1.211.243 (talk) 18:06, 6 December 2024 (UTC)

[edit]Mac window behavior
[edit]Recently in MacOS, when I drag a window laterally by its title bar, sometimes it blows up to nearly fill the screen. Why? —Tamfang (talk) 23:23, 7 December 2024 (UTC)
- Presumably the window has a maximized state and you're switching to that state. Perhaps your mouse movement is being misunderstood as a touchscreen swiping gesture, if such a maximize gesture exists on the OS, and perhaps you can switch gestures off in the settings. Another possibility is that your mouse has a fault (low battery or a broken button) and is sending double-click messages sometimes, making the window maximize in response to a double-click on its title bar, if those are understood by the OS as maximize. Do you find the title bar slips from your grasp sometimes, as well? That would imply a mouse hardware fault. Card Zero (talk) 00:13, 8 December 2024 (UTC)
- The double-click hypothesis is at least worth testing next time it happens. —Tamfang (talk) 22:04, 8 December 2024 (UTC)
