CRC32 Catches Errors, but then What's the Point of SHA?

Cyclic redundancy checks are for quickly checking data integrity, mainly for detecting accidental data corruption. CRCs are not meant to be attacked, not even by your little brother, they are easily reversible, and have one application. Think of the CRC as functioning along the lines of a hand-held calculator.

Cryptographic hashes can help protect national-level strategic intelligence against well-funded, highly efficient adversaries, and data like the world's most important financial transactions. Cryptographic hashes expect vigorous attack from the best attackers, and they have many, many, applications such as creating cryptographic primitives, which is serious business. Think of cryptographic hashes as workhorses for our modern, highly computerized cryptography.

Your question does make sense based on what you observed. But the point is that cryptographic hashes can do so much more than a CRC. A hand-held calculator from 1980 can multiply 25519 and 7.

11. IBM's Summit supercomputer can do that too, at 200 petaflops a second, and get the same result. But that does not mean that the calculator and supercomputer have exactly the same abilities

If crc or CRC32 is specially designed to catch errors, then what's the point of SHA or md4-5 or any other hashing function? What I did was, I had a 190 mb png file (rendered in 16k resolution with blender lol) and I took its sha256 and CRC32 hash, then I did the same, only changing 1 bit of the image. Just 1 bit. And I got a different crc, but also a different sha256

190 mb 1 520 000 000 bits,

So what's the point then, if they both detect such small errors?

What Are the Effects on Hearing of in Ear Headphones?
What Are the Effects on Hearing of in Ear Headphones?
The main effect on hearing is the volume of the sound. Both the intensity and duration matter. However, it seems like hearing loss from personal music players is not as prevalent as from other causes like gunfire or occupational noise exposure (see also here).The specific problem with in-ear headphones is people tend to listen to them louder than other types of headphones, here is an example study that shows this result. So, in summary, there is not anything wrong with in-ear headphones if you listen at a low volume, but be wary that peoples' tendency is to listen louder with in-ear headphones, and you already mentioned liking loud music. The volume is going to be your problem.Be very wary with your hearing though: once you have lost hearing, there is no way to get it back at this time. Hearing aids only temporarily compensate for the loss. You might be okay now but regret a lifetime of noise exposure by the time you are an older adult.References:Clark, W. W. (1991). Noise exposure from leisure activities: a review. The Journal of the Acoustical Society of America, 90(1), 175-181. Hodgetts, W. E. , Rieger, J. M. , & Szarko, R. A. (2007).

Best Cheap On Ear Headphones?Sorry, but quality DOES have a price and it is NOT that low! If REAL quality is an issue, please go for REPUTABLE brands only such as B&W, Sennheiser (most affordable), Shure, Grado, Denon, AKG, Audio-Technica (NOT to be mixed with Technic which is utter rubbish as well!), Etymotic or Beyerdynamic. Things like V-Moda, Klipsch, Sony, Panasonic, JVC and Philips are ONLY "okay-ish" indeed. Please do NOT fall a victim to FASHION ACCESSORIES by buying Boombox, Ministry of Sound, Sol/Republic/Revolution, Noontec Zoro's, Benetton, a-jays, iFrogz, Marley, Fanny Wang, Razer, Karl Kani, WESC, Turtle, JH, Dr.Dre/Beats/Solo, Ludacris/Soul, Koss, Skullcandy, Lady GaGa, Skullcrushers, Monsters nor Bose, because they are ALL seriously overhyped and overpriced "fashion blingbling gimmicks" with a very poor durability and sound quality, NOTHING else (and those who try to claim they are good do NOT know ANYTHING about QUALITY anyway!), BE THEM FAKE OR NOT! Also, please do NOT go for the overly thumping bass that only distorts everything else, focus on GOOD sound quality and durability IN GENERAL.2. What is the best pair of over-the-ear headphones?Panasonic Retro Headphones - (RP-HTX7-G1) *This model number is for the green ones which I have, There is also Red and White..and if you search online, Pink can be found* I bought these at Target on sale for $39.99 They are by far the best headphones that I've ever had. (And the cutest!) They are also very soft, and cushy so they do not hurt your ears. Regular price (At Target) Is $57.99, but they can be found online cheaper.3. What are the best over the ear headphones for sound quality and noise insulation?Well, according to hi-if afficionado Steve Gutenberg these headphones are THE best in the world:Abyss AB-1266 headphones run $5,495, but they are worth itNow, you can try on your Sony's, Sennheisers, AKG, Beyer etc but if you want some excellent headphones those are for mere paupers. Sell that new car back to the dealership and buy a runaround and make yourself truly happy... life is simple than you think!Qualifier:i do not sell audio equipment for a living, nor work in any aspect of audio. I use audio equipment at home. I do not own a pair of the above headphones because I know I will listen too much and too loud on them and so would finish off my hearing. Steve Guttenberg has been in audio a very long time and has been a professional reviewer for many many years. He has listened to probably many hundreds of headphones over the years (along with much other home audio equipment). I enjoy his YouTube channel as the shorts are just enough to watch each episode. I am not affiliated to Steve Guttenberg in any way.What are the best over the ear headphones for sound quality and noise insulation?

Why Does Music Sound Bad When Played Backwards?
Why Does Music Sound Bad When Played Backwards?
Why does music sound bad when played backwards?Eric, Classical music, and really, most kinds of music, sound odd when played backwards because the harmonic progression does not lead where you expect it to. Without going to deep into music theory, I will outline the basics.A typical cadence, or ending of a chord progression, is a IV chord to V to a I chord. (Roman numerals signify chords built out of a major scale, starting on that degree of a major scale, so V is the fifth scale degree.) This cadence is a very typical one, and you will hear it everywhere. What that cadence does, is go from the chord with the most tension in the key... to the tonic, or home chord of the key. In this way, you have tension and relaxation, which is the foundation of harmony. A more advanced chord progression might go I-vi-ii-IV-V-I. This progression sounds different, but it still ends with that characteristic IV-V-I, also called a Perfect Authentic Cadence.Now getting into one of the reasons music played backwards sounds so odd: Our ears expect that Perfect Authentic Cadence. (Simplifying here, there are other pleasing cadences.) Sometimes, a composer will do a cadence like: IV-V-vi. This cadence is called a Deceptive Cadence, because your ear will expect the IV and V to inevitably lead to I. When it goes to the vi you get a denial of expectations. While I am simplifying, these basic ideas of tension and relaxation are what gives music it's sound, feeling, attitude, soul, etc.When these characteristic cadences and progressions get reversed, it essentially throws that whole system out the window. Now you are going I-V-IV-ii-vi-I and not only does that defy expectations, your brain likely is just going WTF?!? For lack of a better term...To hear these cadences for yourself play this on the piano: Courtesy this Wikipedia article: To hear a recording of just these three chords, go here.Hopefully this makes sense!— — — — — —How has learning music theory changed the way you listen to music?Because music theory is generally key to the compositional process for classically trained musicians. When the musical stave first developed (Guido d'Arezzo [c.995-1033] is credited as a pioneer in this field), composers could for the first time conceive their ideas by working them through in writing. It was at this time that the more complex art of counterpoint evolved as a result.Now, if you are a genius like Mozart, you might well be able to conceive a symphony or concerto in your head and then simply commit it to paper. However, most of us lesser mortals are very grateful for the opportunity to work our ideas through. So was Beethoven, by the way -as his sketch books bear ample testimony.How all this has changed the way I listen to music is that I now hear it from a composer's perspective. There's an old maxim "Hear with the eye, see with the ear"; this is what music theory/composition has developed in my faculties of response. Music can be appreciated at different levels, but if you have studied music theory and composition, your critical faculties are more highly attuned as to what is going on in the music. You see, as composers we are engaged with certain events that lie below the surface presentation of music. These events may not be at all apparent, therefore, to the casual or less informed listener. Nevertheless, they contribute to the overall auditory experience, but at an enhanced level to the trained musician who is seeking to follow the composer's thought processes in greater depth.When you are working on paper (or nowadays on a computer screen quite often), you are innately occupied with the idea of "perfection" - getting things "just right" because by writing them down they are achieving a form of permanence and public scrutiny (including ones own). At this level, it goes against a composer's instinct to "cut corners" whereas work of an improvisatory type, by virtue of the instantaneous nature of its conception, cannot have received the same level of intellectual consideration. This by no means relegates improvisatory music to a lower tier necessarily; but it does require recognition on the part of an informed listener to have different expectations from those which he applies when listening to paper conceived music. This can sometimes prove to be more of a challenge, therefore, for the trained musician than the simple music lover unconcerned with background technique

Do You Think Long Hair Will Be Fashionable for Men Again?
No. Less than 1% of guys look good with long hair, like Fabio or Adrian Paul from the old Highlander TV show1. Is it ok to have a cheerleader with really long hair?No, do not cut it off! Long hair is really prettyy!:)2. my sis-in-laws bathroom sink is clogged. she put baking soda and vinegar combo down and boiling water.?could be hair if she has long hair. drano, lye or acid based drain cleaner available at most hardware stores. BE CAREFUL WITH THIS3. Do girls like my hair? (i got pictures)?I love it way better with long hair. I think that the long hair is more attractive4. Hairstyles for girl with oblong face and thick, wavy hair?Girls who have 'long' faces generally look better with their hair away from their faces. Since you like long hair, wear it with a headband, combs or pull the front sections of your hair away from your face and secure it with an elastic band at the back. This will keep your long hair from causing your face to look longer than it is. Ponytails and bangs can also be flattering to your facial shape5.

How do you put ur hair in a bun.?I even have long hair & what i do is, first positioned it in a severe ponytail with out tying it. basically carry it there. then save twisting the ponytail in the comparable directional tightly till the hair starts to twist to the side by skill of itself save twisting at the same time as slowly making your ponytail right into a spiral then as quickly as you have that bun, tie it with a hair tie!7. older women and long hair?My mom & grandmothers all have short hair and having grown up with only seeing older women with short hair, you just come to accept it as normal. I think the reasoning behind it is that when you get older, you have less motivation/reason to spend hours grooming yourself and short hair is easy & convenient. To be absolutely honest, the older women that I have seen with longer hair look very elegant and stunning and I am definitely FOR it! One of my grandmother's friends has silvery grey/white hair to her elbows that she always wears in a bun and it looks stunning... I hope my hair looks that great when I am her age!8. Why do people call me emo?Because u have long hair? You said if u have long hair ppl think ur emo. Dude u ansered ur own question. And dude deal with it and dont thrash emos ppl call me it all the time because i have alot of aspects of the steryotype emo. Like apparently my hair is emo because my bangs cover one eye.

Make sure you rub thoroughly, and dont hold back on the shampoo. if it is a dog with long hair, make sure he/she is getting frequent cuts. long hair is part of the cause. The second is conditioner. do the same with the shampoo, but leave the conditioner on for 10 mins. And make sure it is 10 mins. And rub thoroughly. massage all over the dogs body. And lastly, buy a pet cologne. They really do work For shampoo, use something that is silky, and has a berry scent to it. Same goes for conditioner. make sure conditioner has some sort of oatmeal in it. Hope this helps. Good Luck
China Has Successfully Manufactured the First 3D Printed Specimen of Nuclear Reactor Pressure Vessel
China Has Successfully Manufactured the First 3D Printed Specimen of Nuclear Reactor Pressure Vessel
Recently, China has made new significant progress in the application of 3D printing technology in the field of nuclear energy - China Nuclear Power Research and Design Institute, in cooperation with Nanfang Additive Technology Co., Ltd., has successfully manufactured the cylinder test piece of acp100 reactor pressure vessel through the self-developed electrofusion additive manufacturing (3D printing) technology for heavy metal components.It is understood that the 3D printed specimen weighs 400kg, and after testing, its material chemical composition and basic mechanical properties meet the requirements of international nuclear power code RCC-M and ASME. The successful 3D printing of the pressure vessel specimen marks a solid step forward in the overall goal of cooperative two-way small reactor pressure vessel additive manufacturing and product application.Acp100 is a multi-purpose modular small reactor independently developed by CNNC. It can not only be used for power generation, but also be comprehensively utilized, such as heating, seawater desalination, refrigeration, industrial heat, providing energy for offshore platforms and power for ice breakers. At present, acp100 modular small reactor has completed all scientific research, become the world's first small reactor technology that has passed the general reactor safety review (grsr) of the International Atomic Energy Agency, and has the conditions for project implementation.The combination of emerging manufacturing technology and new nuclear power reactor type will bring revolutionary changes to the traditional design and manufacturing in the future. The successful printing of acp100 pressure vessel cylinder specimen is of positive significance to the engineering application of Heavy Metal 3D printing manufacturing in the field of nuclear power. It can be predicted that the application of this technology in the field of nuclear power will greatly shorten the equipment manufacturing cycle, reduce the equipment cost, improve the equipment quality and the safety of reactor equipment, and provide important technical support for the improvement of nuclear power equipment design and manufacturing capacity, the concept of "made in China 2025" and the implementation of nuclear power "going global" strategy.

Another approach to shortening names to create a directory link, so the folderC:UsersMyUserNameDocuments will have the alternate name of C:short.I have not tested how it works in the problem cases, but it should performbetter since it is still inside the same disk.I think you cannot create a directory link in the root folder C:, so youmight need to create a short sub-folder name, even one letter, such as C:dand create the link inside it.The Windows command to use ismklink,which has two variants:Soft link pointing to a directory:Hard link pointing to a directory, also known as a directory junction:For more information about links, see for example the articleThe Complete Guide to Creating Symbolic Links (aka Symlinks) on Windows.• Suggested ReadingUsing Alt Keycode for accents?First hold CtrlShift, then tap U and let go.An underlined "u" will appear, to which you can append a combination of characters. Hit enter after that and the new character will appear.For instance, if I hold CtrlShift and hit U, type e9, then hit enter, an appears. If I hit e8 instead, an does instead.You can find the correct combinations using the Character Map program in Accessories. The first "0" or two that you find on certain entries can be dropped (e.g. a is listed as 00E7, but you only need to type the e7).It's a bit odd coming from using the Alt method in Windows, but you'll acclimate quickly.N.B.: If you need to frequently type many types of accented characters see Adam Byrtek's answer below for a nice method that, while it requires some setting up, can save a lot of time in the long run.------Launch a GUI Tkinter program on bootYes it is possible to launch Tkinter Python program to the Pi console. What you have tried should have worked. However, if python /home/pi/guiprog.py has a end, a window will appear and run the program to the end and then close the window before the system completes the boot. A good test would be to have a lxterminal and execute the command python /home/pi/guiprog.py launches command window no gui. Did that work? if yes, that is good. Next exec lxterminal -e 'python /home/pi/guiprog.py launches command window no gui'. If the new lxterminal stay open, it should also work on boot up.A GUI EXAMPLE:You have to keep the window open as in "mywindow.mainloop()" or some other way. Note, as I put the program in /home/pi/bin a boot is requited after creating the bin directory------How to use BCDEdit to dual boot Windows installations?You need a BCDEdit /set command for configure the boot volume. Then add the entry to the Windows Boot Manager operating system menu by calling the BCDEdit /displayorder command. It will identify the other OS' partition or the following command as wellThe following line makes the entry bootable by adding it to the menu You can verify that the new entry will appear on the boot menu by running the command bcdedit /enum ACTIVE and looking for the Windows Legacy OS Loader entry.Note: /create command is used to add non-Microsoft OS to boot loader entry.For more information regarding this you can read this source articleRegarding your question about "Difference between Windows Boot loader and Boot manager"From wikipediaSee also on technet.Visual BCD Editor is an advanced GUI version of Windows bcdedit utility.Download page for visual BCD editor.Give a try to repair option in the tool.------Windows Vista and 7 crossrealm authentication MIT KerberosThe following two links have some detailed information on the SupportedEncryptionTypes configuration for Kerberos: general, you need to have common algorithm between the KDC and your Windows machines. If you are running more recent version of MIT Kerberos, you should have AES support, but if your KDC is older one, you would need to use DES to interop. @tommed is correct that DES is disabled by default in Win7, but it should work fine on Vista. Alternatively, capture the network traffic between the KDC and your client machine and look at what the client is offering and look at the KDC config to ensure you have at least one of the crypto algorithms in common.------Slow SQL Server authentication, but fast SAN, fast querying?Here is your answer:If MSDB is on c: master is on c: as well and I'm almost willing to bet that tempdb is still in the default location as the average I/O stall on c is 19 seconds!First, check if tempdb is on c: or has any file on the c: partition and if so move it awayCheck if the master database has some free space - Usually you dont need to tune it as very little is written to the master database, unless if someone has created objects in itThen make space in the MSDB database is way to big which can cause a lot of troubles, please remove as much backup and job history from it database as you can. You can do all these checks very simply by downloading and running sp_blitz------Is Windows 10 backup safe from ransomware?Generally speaking, most ransomware tries to encrypt both the main drive, as well as any attached drives (USB, network shares, etc). My bet is if it could find your backup files, they would be encrypted as well (had someone get an early version of Cryptolocker and encrypted all the network shares). Backups (with a defined backup policy) saved us from paying out.This is why either an offline backup (i.e. external HDD not permanently attached) or a cloud backup is so important. Something that cannot be immediately accessed should your computer be compromised.I should note that Windows (all versions going back to XP) uses its own proprietary incremental backup system. It builds a backup file and then increments the data with each subsequent backup. This is more than sufficient to keep your data safe (provided you have an offline drive)------Easy way to type accented charactersAs joulsauron said in his answer Stack Exchange cannot do anything for this. This problem has to be dealt on your own PC. That can be done by changing the keyboard layout. I will post ways to change the keyboard layout on different OS. Click on System -> Preferences -> Keyboard Then click on the Layouts tab and then click on Add A new window will open. Click on the By Language tab. Select language as "Spanish, Castillian" and select whichever variant suits you best (By the way I chose Spain in the variant). PS for quick changing between layouts there is a shortcut keypress Shift Caps LockORYou will also get an icon on your taskbar, use it to change quickly. See this article on wikihow.com Refer to this article on Official Microsoft Website------Why are my backups using so much space? ORA-19804I've managed to make the error go away, for now at least. I'm putting the conclusion here as a community wiki answer since it leaves some things unexplained.After bypassing rman and deleting the oldest files manually, it was necessary to:which convinced rman that it had enough free space to start working again. A level 0 backup completed successfully after that cleanup, and a level 1 backup completed successfully the next morning.A notable feature of this solution is that this:still says that it is using the 31 day window, and doesn't list any files needing to be backed up. The way I figure it, that means the files that were deleted were in fact obsolete.control_file_record_keep_time has also been updated to 39, following the recommended formula. Hopefully, this was the root cause of the problem, and automatic deletion will work from now on------Is there a high end expensive photo transfer cable for my Olympus E-520 DSLR to PC?Camera makers seem to have been among the last electronics manufacturers to completely adopt standard USB cables.Olympus point-and-shoots in particular took a long time to come around to standard USB cables. The camera-end of the cable has a proprietary connector, which is also used for non-USB connections such as wired remote shutter release, A/V breakout, etc.I have seen the cable your camera uses referred to as "CB-USB6". I don't believe that's an industry-standard name, and I don't know if that's how Olympus refers to the cable. But searching for "Olympus E-520 replacement USB cable" returns several product links with the same cable:Note the camera-end connector: it is not a standard USB A/mini-A/micro-A or B/mini-B/micro-B connector.As far as "high-end expensive USB 2.0 cable", I'm not sure what you mean there. Being non-standard, this cable is what it is------Creating email alert from object with email as From email addressI don't believe you'll be able to use a custom field as your from address for e-mail alerts. You can't even use the standard e-mail field on a contact as the from address for an alert. However, you can create a trigger to send e-mails when a new contact us record is created. The documentation for sending e-mails via Apex Code is here: Outbound Email docsHere's an example trigger:Another suggestion would be to use e-mail alerts but instead of having the e-mail come from the person who filled out the contact us form, add a mailto: link in the message that the responder can click on that will open a new e-mail window with the e-mail address and subject pre-populated. For example: ">Respond to this contact request.------Windows 8 shortcut keys for Modern UI (tiled) AppsJust create a shortcut in your desktop and assign a Hotkey:For example: This is for People app1. Create a new shortcut in your desktop: using the following formatApp's URL Protocol name? read about it at the end2. Open its properties dialog and setup the hotkeys you want to useAnd that's it, now you can launch your Windows 8 applications with that hotkeyApp's URL ProtocolSome applications have their own URL protocol to open its supported files, something similar to or mailto:And you will find those names in windows registry : HKEY_CURRENT_USERSoftwareClassesThere you will find some of your applications (not all of them), just look for the ones with default value like this one:Another hint is that they also have a string value called URL ProtocolHopefully, you will find your desired-application's URL Protocol name. Good luck!------Open ebooks in Ubuntu 12.04Install Calibre. It's an eBook Management program. It has dozens of plugins and features to cover pretty much any possible ebook related need, including Robust Conversion tools, as well as an eBook Extractor/Modifier. Just import a book into Calibre and then right-click on it and select "Tweak Book".The "Tweak Book" feature might only support EPUBs but you can just convert most other formats into your desired format using Calibre's Conversion tools.EDIT: As of version 1.15 of Calibre, The old "Tweak Book" feature(extracting the book and presenting a folder to edit) has been replaced by a full on EPUB/AZW ebook editor. If you still wish to simply extract EPUBs into their respective parts, simply rename the EPUB file to "NAME.zip" and open them using a standard File Archive program like "File Roller" in Ubuntu.

I wear mine.Generally speaking, displaying where you got your degree from on a business card or a door sign would be seen as odd, at best. If somebody handed me a business card with the Harvard logo on it and he didn't work at Harvard, I'd probably ask about it: "Oh, do you do work with Harvard University?" and if the answer was, "No, I just attended" I'd find this an unpleasant level of showing off. Not classy.A lot of Americans will have college-related paraphernalia in their offices, though. Like, you may see a pennant or they may have their degree(s) up on the wall. This is a more casual display of affiliation.Likewise, the ring is casual. Class rings are usually not that obtrusive, particularly the signet variety.Usually, the signet is only immediately recognized by others who attended the university (though I have had people ask me to hand over my ring so they could take a closer look at it before), and thus it kind of acts like a secret handshake. I've had people from my college recognize my signet ring on sight, and then we have an instant connection.It's just a lot classier than shoving it in everybody's face all the time in an American social environment, basically.
