37,542,206 | We have data (not allot at this point) that we want to transform/aggregate/pivot up to wazoo.
I had a look on the www and all the answers i am asking is pointing to hadoop for scalable,cheap to run(no SQL server machine and license),fast(if you have allot of data), programmable(not little boxes that you drag around).
There is just one problem that i keep coming up against
namely 'Use hadoop if you have more than 10gb of data'
Now we don't even have 1gb of data(at this stage) is it still viable.
My other option is SSIS. Now we do use SSIS for some of our current ETL but we don't have resources for it and putting a SQL in the cloud is just going to cost to much and don't even get me started on scalability cost and config.

] | Your current data volume seems to be too low for making an entry into hadoop. Enter into hadoop ecosystem only if you are dealing with huge volume of data(TB/year) and if you suspect the data volume to increase exponentially down the line.
Let me explain why I suggest against hadoop for such low volume of data.
By default hadoop stores your files into 128MB chunks of data and while processing also, it takes 128MB Chunks at a time to process(parallely). If your business requirement involves heavy CPU intensive processing, then you can decrease the input chunk size from 128MB to less. But then again by decreasing the amount of data to be processed parallely, you'll end up increasing the number of IO seaks(low level block storage). At the end you might be spending more resource on managing the tasks rather than what the actual task is taking. Hence, try avoiding distributed computing as a solution for your(low) data volume. | As @Makubex has suggested, don't use hadoop.
And SISS is a good option as it handles the data in-memory so it would perform data aggregations, data type conversions, merging, etc at a much faster rate than writing to the disk using temporary tables in stored procedures.
Hadoop is meant for large amounts of data I would suggest it only for data in terabytes. It would be way slower that SISS(which runs in-memory) for small data-sets.

Yes, the bracketed expression is an absolute clause.
It qualifies as an absolute because it contains a subject and is subordinate in form, but has no syntactic link to the main clause.
Absolute clauses are a type of 'supplement'-- neither dependent nor headed. And they are not modifiers either; rather they have a sematic 'anchor' that they refer to. The natural interpretation here is one of contrast, cf:
*Though most politicians are downplaying the dire economic situations the people are facing, this candidate stresses that improving the lives of the citizens is a matter of import.* | Sentence 2 is not OK. Removing "while" and "are" transforms the first clause into a fragment, incorrectly placed ahead of the next clause. "Most politicians" is the subject, but here is no verb associated with it.
Put into a more natural order, sentence 1 is:
>
> 1. This candidate stresses that improving the lives of the citizens is a matter of import, **while** most politicians **are** downplaying the dire economic situations the people are facing.
>
>
>
Still not good enough, sentence 1 can be transformed into:
>
> This candidate stresses that improving the lives of the citizens is a matter of import, **and** most politicians are downplaying the dire economic situations the people are facing.
>
>
>
but a good part of the meaning is lost.
The fragment:
>
> Most politicians downplaying the dire economic situations the people are facing ...
>
>
>
can be correctly used in a sentence like:
>
> Most politicians downplaying the dire economic situations the people are facing *are now in vacation.*
>
>
>
In this last example, the same fragment is an absolute phrase.
---
In the case of an absolute phrase, the absolute phrase is **strongly related** in meaning to the rest of the sentence. In the original example, "most politicians" and "this candidate" are actually presented as conflicting, not as a unit.
---
To better understand the absolute phrases, you can study the following examples (from [here](http://softschools.com/examples/literary_terms/absolute_phrase_examples/420/)).

48,825 | **Short version**
How can I determine the Java version a remote server is running if I only have access to the server through port 443?
**Long version**
I am validating a pentest run by another group. They found an error message that provided the Java version being run by the remote server. The Java version was an old one. The developers have apparently made changes that prevent the error message from appearing, thus hiding the Java version.
My job is find out if the developers also updated the java version. How can I do that without access to the server other than through HTTPS via port 443? | 2014/01/16 | [

] | Are you validating the results or the server? You seem to be confusing the two.
Preventing info disclosure through error messages is a good thing. You verified that is fixed. It doesn't seem to be your job to validate that the Java version is updated (since it appears to be a black-box test), for that, you leave that to the server operator to report on. Make a note that it's no longer obvious what the version is, and encourage the report audience to validate the server to confirm. | Well Ideally a secure server would do a pretty good job hiding this information. There is no hard set way. Two good ways are by examining the server response headers and looking for error pages. There are a lot of tools online made for things like this.
I would recommend starting by looking at server response headers, and if that doesn't reveal anything try to create errors by supplying invalid input and requesting pages that you know are broken or don't exist. |

St Pancras International is on three levels. When you arrive on the Thameslink you are on the lowest, below ground level. Take the escalator or lift to the exit. Keep your ticket handy to operate the gates. There is a wide gate if you have a wheelie bag with you, I think it is to the left. When you exit the gates turn left and you will see the exit you need on the far side of the concourse.
When you exit STP you cross the road and you are in King's Cross station. The departure boards are in front of you. Beyond them are the low-numbered platforms from which the long-distance trains depart. To your left is a smaller block of platforms from which, I my experience, the trains to Cambridge usually leave. I say usually.
If you want to buy a sandwich or get a coffee you are better off to do it at STP, you will already have noticed the shops to your left as you walked through there. You can do this at King's Cross but most of the outlets are on an upper level with escalator. There are free toilets at STP (which is unusual in a British mainline station) but they are up two irritating small steps which impede wheelie bags.
It takes about 2:20 according to the National Rail website.

1. Take the Thameslink to Farringdon.
2. Cross over to the tube side of the station. There should be lifts. (Lifts for return journey are out of action at the moment but it's only about 5 steps.)
3. Take any eastbound tube to Liverpool Street Station

St Pancras International is on three levels. When you arrive on the Thameslink you are on the lowest, below ground level. Take the escalator or lift to the exit. Keep your ticket handy to operate the gates. There is a wide gate if you have a wheelie bag with you, I think it is to the left. When you exit the gates turn left and you will see the exit you need on the far side of the concourse.
When you exit STP you cross the road and you are in King's Cross station. The departure boards are in front of you. Beyond them are the low-numbered platforms from which the long-distance trains depart. To your left is a smaller block of platforms from which, I my experience, the trains to Cambridge usually leave. I say usually.
If you want to buy a sandwich or get a coffee you are better off to do it at STP, you will already have noticed the shops to your left as you walked through there. You can do this at King's Cross but most of the outlets are on an upper level with escalator. There are free toilets at STP (which is unusual in a British mainline station) but they are up two irritating small steps which impede wheelie bags.

371,863 | I'm extremely worried about my MacBook. I tried updating to the official release of macOS Catalina a few hours ago but instantly hit a problem. I have not installed any beta releases beforehand.
I downloaded the updated and selected my drive as the install location. After a few minutes of the update seeming to go as normal, I was thrown a screen which said something like "macOS could not be updated on your Mac, there is not enough free space". It gave me the option to restart so I did that, hoping that I'd be able to log in and clear some more space for the install.
However, I restarted, entered my password then it seemed like the update instantly resumed. A few minutes later, the same error popped up so I pressed restart once more and the same cycle happened again.
Frustrated, I tried the obvious booting into recovery mode and selecting my main drive as the startup disk but whilst I was able to enter recovery mode, I wasn't able to select the disk - it didn't appear. I also tried booting into safe mode with no success.
I have done a lot of googling and most guides say something like "restart, log in and free up some space". The issue is, I can't log in. When I try to, it chucks me back into the update and the process repeats.
I would greatly appreciate it if someone could help me out - this issue is really concerning as I'm currently unable to use my MacBook and really need it for my studies. | 2019/10/08 | [

That means what in case of restart loop because of lack of free space you need to boot into recovery mode by holding `Cmd` + `R` right after machine starts, and go into **Restore from Time Machine Backup** there: you will have local time machine backups and will be able to restore system to its state just before the upgrade.
You don't need an external disk with Time Machine copy to do that, APFS does this for you automatically.
Deleting a file from APFS from recovery mode would not free any disk space because of the snapshot system, mentioned above. | I ran into the same problem yesterday with zero help from a senior advisor despite opening a ticket with engineering.
I finally resolved it by: Downloading (but not installing) Catalina on another Mac and copying the install file (big!) to an external drive. I then booted the stuck Mac to an external drive I have running High Sierra, wiped and reformatted the stuck drive, then installed Catalina from scratch. This worked, and then restored from Time Machine backup; only way I was able to get around this issue without reverting to Mojave.
Also if you come across and issue where it won’t open your TM backup because there “aren’t any volumes” skip the usual restore process and set up as new. Create an dummy account and login; then open your TM backup so the disk image is mounted in the Finder. Only then you can run the Migration Utility and it will be able to restore from your backup.
Complete nightmare but finally upgrade completed; definitely not doing my other Mac for a while. |

] | I was facing the same issue and was on the verge of reformatting my macbook.
Here's what fixed the issue for me. I'm not sure if step one was necessary, but since I did this en route to fixing the loop of death, I'll list it here for you to consider.
1. **Try to reinstall Mojave (this won't wipe your disk)** - I wanted to return my macbook to as original a condition as possible, and I figured attempting to install Mojave was the best way to do it. Since I couldn't boot from "Macintosh HD" anymore (I was just getting a white circle with a bar across it), I rebooted my macbook and pressed Cmd + r. This helped me boot into recovery mode. Once there, I clicked on "Reinstall macOS". Don't worry, you won't lose your data doing this as it merely overwrites the OS, it doesn't overwrite your files. Once you do so, and assuming you're connected to Wifi, your macbook will start downloading Mojave and eventually attempt to install it. After an agonizing 30-40 minutes, it'll give you the same error - "not enough free space to install the OS".
2. **Try restoring from Time Machine Backups (you might actually have one)** - I cannot emphasize how strongly I believed I didn't have one of these backups, but unbeknownst to me, it did exist on my drive. Even if you're convinced you don't have one, it doesn't hurt to give this a shot. Reboot and go into recovery mode again (press cmd + r during reboot). This time when the options pull up, choose "Restore from Time Machine Backup". Now, as I mentioned before, I thought I hadn't got this turned on, but I guess it was turned on by default by the OS. Your macbook will prompt you to pick a disk where the time machines are stored, and I picked "Macintosh HD". When I clicked this option, I saw about 5 backups populate from today itself. I picked one of them that felt fairly far away from the moment I had began installing this OS. For example, if I started my installation at 4pm, I decided to pick up the recovery from 2pm (even though there was a backup available from 4 pm).
It took all of 5 minutes for the backup to be restored. And all my files were intact, even though I had explicitly moved out/deleted about 30G of files while trying to debug the installation issue.
Godspeed. | I followed TA's answer above although I only did step 2 - restore from Time Machine. And that seems to have worked so far.
It took about 2 hours to restore 200GB, and it was a bit nerve wracking since I had to erase my HD before doing the restore (maybe this wouldn't have been necessary had I followed step 1 and reinstalled Mojave). I thought I had plenty of space before I tried the Catalina upgrade. I had just deleted (and emptied trash) of about 50GB of Xcode device support files. So I don't understand why Catalina had the space issue for me. I'd also been reindexing Spotlight and turning off Filevault prior to the Catalina issue so maybe those were contributing factors. One tip that may be really useful for people is that if you have a wireless mac keyboard, Command R to get into recovery mode might not be easy for you to initiate.

Godspeed. | I ran into the same problem yesterday with zero help from a senior advisor despite opening a ticket with engineering.
I finally resolved it by: Downloading (but not installing) Catalina on another Mac and copying the install file (big!) to an external drive. I then booted the stuck Mac to an external drive I have running High Sierra, wiped and reformatted the stuck drive, then installed Catalina from scratch. This worked, and then restored from Time Machine backup; only way I was able to get around this issue without reverting to Mojave.
Also if you come across and issue where it won’t open your TM backup because there “aren’t any volumes” skip the usual restore process and set up as new. Create an dummy account and login; then open your TM backup so the disk image is mounted in the Finder. Only then you can run the Migration Utility and it will be able to restore from your backup.
Complete nightmare but finally upgrade completed; definitely not doing my other Mac for a while. |

] | I had the same problem yesterday on a 2013 Macbook Air and was able to restore a Time Machine backup.
The update failed due to limited space, but it wasn't able to boot into Mojave anymore because it couldn't find a bootable disk anymore.
I tried freeing up space by manually moving the iTunes folder (~20GB) to an external drive from the terminal, but somehow it did not seem to see the extra space. It kept complaining about too little storage space (the disk repair tool saw only 11GB available).

* The reinstall of Mojave failed, again because of free space issues.
* Then I tried to restore a Time Machine backup and also found a backup from just before the update which I hadn't expected. This restore was finished in 2 minutes and Mojave was up and running as if nothing had happened.
The next step is to make another backup, clear out even more space and re-try the update. Fingers crossed!

Also, if you create another copy of Form1 called Form2, you can make changes to either one without worrying about those changes affecting the other form. Resources.resx works in just the opposite manner. If you make changes to a resouce in Resources.resx, all classes that use that resource will be updated.

Resources.resx is meant for global(common) resources for the entire project. Generally meant for sharing stuff! | **Be extremely cautious when you toy with resx files in Visual Studio!!!!**
Chances are you will soon crash your project when you try to change / add / edit / delete form's level resources.
You are better off using project's level resource file.
There are several types of resources, like Strings, Images, Audio, Icons, Files etc.
The project level resources are useful to share resources - mainly graphics - among all your forms:
You import a graphic once from Project Menu / myProject's Properties / Resources / Add existing file menu item.
Be wary that **once you've added a resource**, and USED that resource within your project, **you should NOT remove it** from the resource file whithout being CERTAIN you do not use it any more, otherwise the resource will be deleted, but NOT references against it, and you'll get compile time errror, or even worse, runtime errors.
Likewise, imageList control embeds graphics at the form's level. But those aren't shareable between forms, so if you think you're going tu re-use a graphic, you're better off adding it as a global resource at application - project's level.
Besides, imagelist are very difficult to maintain - evolve.
**For copying an existing form to a new one**, within the same project or another, DO NOT copy/paste the formxxx.vb file.
Idem, do not copy / paste a resx file from one project to another.
Here is the rather cumbersome process you should use:
**1 - To copy a form to the same project:**
Provided there is NO custom form's level resources (added by you):
Create a new empty form and make it the same size - and other properties as needed - as the original form. Yes, manually.
From the original form's design type Ctrl+A to select all its controls, and copy them to the new form.
They will keep theyr name and properties.
Do the same for the code: copy / paste.
Pay attention to delete the 1st line after the Imports: Public Class myOriginalForm
**2 - To copy form(s) to another project**, you should first make sure all project's level resources are identical. And NOT by copying indiividual resources from the resource folder!
Instead, carefully Import the resources in the new project, using the Add Existing Resource menuitem. You can import several items at a time.
This way, your resources will be properly referenced. |
1,224,980 | I'm afraid this is a very generic question, but unfortunately my question is exactly how to get down to the 'specifics' on this particular issue. Let me be more specific:
**I want to create an "email listener" application** - something that would run in my server, so that users could send email to a particular address and this application would fetch the email and do something with its contents.

So "C Programming Tutorial" would probably get what you wanted. Something I looked up a while back, "Matrix multiplication in C" would be similar. Also learning to use Google's advanced search has really become a right of passage of sorts for programmers. I know of people on this and other SE sites who have scripts and settings for their browsers to do a lot of that stuff automatically. | If you're searching for a specific programming concept, just put 'C' at the *beginning* of the search.

Unfortunately, Google sometimes likes to be smart and include/exclude punctuation as it sees fit, so you may match things like C++, C#, and so on for a while.
However, Google can be trained, if you're logged in. I search for programming-related items so often, Google often assumes that's what I mean without needing more clarification.

If baby calms down then you know that was likely the problem. Works like a charm for my son. | Perhaps a slippery elm lozenge could be crushed and mixed with a little water to make a paste. My husband takes slippery elm before bed for mild heartburn. Remaining upright will help as well.
(Slippery elm is traditionally prepared as a slimy, gross liquid- if you can find it that way, great. I can only find it in a lozenge at my health food store.) |

418,364 | Occasionally when investigating SQL Server issues I find it useful to be able to attach the Visual Studio debugger to it and try and figure out what it is doing by looking at the call stack (the public symbols are available and often it is possible to infer useful information from the method names).
A great example of the type of internals information that can be inferred is [in this blog post](http://sqlblog.com/blogs/paul_white/archive/2011/08/09/sql-server-seeks-and-binary-search.aspx) which inspired my attempts.
This can be quite a time consuming and tedious process however. Generally I run the code of interest in a loop attach the debugger then continually break and continue until I hit a call stack that looks interesting to the matter under investigation. I can then step through the code and look at the method names being called. This takes ages however.
Is there any way of automating this so I can simply log all the methods called for a short period then review the log file afterwards? | 2012/04/29 | [

The biggest problem we see is with tire installers over-tightening the lug nuts with their impact tools, thus stretching the studs and causing the thread galling as previously mentioned on another post.

But we never experienced a stud failure on any we used grease on and always torqued them to spec. | I ran a fleet of Leyland buses many years ago. Stud breakage was not uncommon on Leylands. Overtightening causes issues as the stud it taken closer to its tensile strength which makes it more prone to fatigue cracks. It can also make it impossible to change a wheel on the road with hand tools. Undertightening allows the rim to move putting bending stress on the stud putting it closer to fatigue likelihood.
Our favourite was to clean the studs allowing them to be checked for cracks. However, they were also checked for physical condition as they had shoulders on them allowing the wheel to be kept away from the hot drum. Sometimes some were worn to different heights causing warping of the rim, again creating an increased tendency to fatigue cracks particularly in the rim. Sometimes we would replace all eight studs. We never changed a single stud, always a full set.
We assembled with anti-seize after cleaning the studs of the gummy stuff that seems to accumulate. Although a torque wrench is preferred, it is not always practical. If you do them up with a one metre tube, then check with a torque wrench, you will get the 'feel' of how tight to do them manually with he one metre tube.
It is then easy to 'manually' check them whilst out on the road. If the wheel brace kit is on the bus, I can go round and check them anytime. Thus the regularity of checking is as important as the 'accuracy' of checking.
Don't forget that running with loose wheel nuts chews the studs out and creates bending forces that are prone to cause fatigue cracks or put the stud closer to an 'end of life 'fatigue crack'. Wheel studs do not last forever. |

The nut rotational friction and bolt clamping force are both affected by the choice of lubricant used or lack thereof. Almost all OEM's specify no lube. This is done for several reasons. Dry results in the most thread rotational friction, a most desirable attribute, this significantly reduces the chances of the lugs backing off and the wheel coming off.
The biggest concern is a wheel coming off at high speed. This is a highly dangerous event because the wheel accelerates ahead of the vehicle as it comes off at great speed and can and has caused deaths.
Of slightly less importance, but still relevant, is that lubricated threads create a higher clamping force for a given torque than specified. This can stretch the studs or bolts, warp the hub flange and/or brake rotor.

] | I would be more likely to use an anti-sieze type of grease on studs or bolts that are more prone to rust. I think that the conical mating surfaces of the nut / wheel provide the friction to keep the nuts tight, so lubricated threads helps to preserve the threads with repeated removal, installation and re-torque of the nuts. | A lubricant should be applied to wheel bolts unless OEM service information states otherwise. Basically when torqueing a bolt the torque does not indicate clamping force. It indicates the resistance to overcome friction. And that friction will result in a torque reading at which the bolt will not have achieved the correct clamping force. By reducing the friction with a lubricant, a much greater chance of reaching the proper clamping force is possible. One problem described by a previous poster mentions tire installers using air wrenches can achieve incorrectly torque values when bolts are lubricated. That should be avoided by either having them hand torque the bolts, or by re-torqueing them after the service has been completed. |

What does "amplify into" mean? Could you paraphrase the sentence for me?
The phrase context is below:

> When we explained convection by the causal mechanism outlined above — a temperature gradient that creates a density gradient that, in turn, *amplifies fluctuations into a circular flow* — we were giving only part of the explanation because the causal chain behind the emergence of a convection cell does not account for the fact that its properties are stable against perturbations.

] | OK:
>
> amplifies fluctuations into a circular flow.
>
>

Let's look at each part of the sentence separately:
* "Amplifies … into": Our context has to do with waves (fluctuations) in heat. To amplify waves means to make them "louder" or more intense by increasing their magnitude. Since the phrase is "amplify into" we are turning something into something else by making it more intense.
* "fluctuations": Fluctuations are like waves, but more general. It means that something is oscillating, or going back and forth. In this case, they are oscillations in temperature.
* "circular flow": This means that the heat is now continuously moving in a circle.
**To summarize:** The sentence means, in simpler terms, "Makes waves of heat stronger and causes them to move continuously in a circle." | The term **fluctuations** is typically used to describe random motion of molecules.
In "steady state" of gas or liquid, all molecules fluctuate, but the average (or "net") movement is zero; think of it as people moving around in a ballroom but not getting in or out of it.
If there is a **temperature gradient** (simply put, hot and cold regions and a transition between them) then, when you look at a single molecule, it still flucuates; but the density gradient (caused by the temperature gradient) sort of **amplifies** the fluctuations with a preference to one direction. The result is that the fluctuations sum out to a nonzero net **flow**.
Therefore, we can say that the temperature gradient amplifies the fluctuations **into** a flow.
The reason for the flow being **circular** is probably beyond the scope of ELL (even more than my answer is already...); it is a scientific topic. |

] | Easy vs. Possible.
Is it possible. Yes. Even with relatively minimal training it is a fairly simple matter to teach someone to transfer enough energy through a strike to cause unconsciousness.
Is it easy? No. Transferring that much energy requires, among other things, striking through the target. If you watch beginning karate students attempting to break boards you will see many of them take several attempts, even though they are punching with all of their strength and with relatively good technique. The reason it takes them so many attempts is that they are focusing the end of their blow on the front side, rather than the back side, of the target. So while they punch with power, the power doesn't transfer to the board in a way that causes it to break.
That doesn't mean it doesn't happen. It does. But it's not a regular occurrence.
Now, where it gets tricky is this: the force needed to knock someone unconscious is very similar to the force required to kill them. It has more to do with the location and direction of the force applied to the brain tissue.
What is almost always false about movies (regardless of if they show a one-punch knockout or not) is the lingering effects of traumatic brain injury. | Yes it is and there are multiple evidence of that on youtube, like these:

Hitting someone on the very top of their head doesn't work-though with enough force can cause concussions. Same with the back of the head (it's a little tougher too). Knocking someone out is simply trying to get their brain to rattle around in the fluid it's in. Easiest way is a punch thrown in a way that would hit a target on the chin. The force required must be superior than the target resisting it. Sucker punches are especially effective because they turn the head when the target doesn't see it-so they don't brace against it. Boxers have trouble doing it because the target should be tucking their chin.
To do it as easy as in a movie, a righty can use a left uppercut (upward fist strike) to hit a target in the head to force the chin up, followed by a fast right hook (punch sent from your right side thru target's chin to your left side). This does work and is very fast (less than 2 seconds to put someone down) if you're accurate and have mediocre force. |

] | It is possible knock someone out with one punch. Searching on Youtube for "One punch knockout" gives you many results (also in boxing).
An [example](https://www.youtube.com/watch?v=CV3TDLRDKIY). (warning, contains violence and some may be fake.)
The [spot](http://www.wikihow.com/Knock-Someone-Out-with-One-Hit) where someone is hit is important though, but it is definitely possible; whether it is easy depends on how well the person hitting and the person being hit know what to do in fights.
Furthermore, boxers of course try to protect their heads from getting knocked out, yet still they also get a knock-out every once in while. | Boxing is even less accurate representation of real life than movies. In fact, everything possible is done to **prolong** the match. Boxers are both trained and equipped to stay conscious as long as possible. Because sport is a show, and longer shows can be priced higher.
On the other hand, movies are like playing roulete with remote-controlled dices. For the sake of the story, things which are merely possible or probable in the real life for fictional characters work with 100% dependability.
Bottom line: Is it possible to do "movie knockout" some time on some guy? - Absolutely yes.
Is it possible to do "movie knockout" every time on every guy? - Hell no. |
35,556 | As a child I watched (with my father) a boxing match which lasted 12 rounds. At the end neither fighter resembled his previous pretty self, but nobody got knocked out either.
I just watched Terra Nova where the main character layed out a kidnapper in one punch. I've seen this a lot in movies. In the movies is so easy to lay someone out by landing a fairly decent blow to the head.
So I have to ask: Are movies giving an over-simplistic idea of how easy it is to knock someone out?

Furthermore, boxers of course try to protect their heads from getting knocked out, yet still they also get a knock-out every once in while. | Vulcan neck pinch does not work. Hitting someone on the very top of their head doesn't work-though with enough force can cause concussions. Same with the back of the head (it's a little tougher too). Knocking someone out is simply trying to get their brain to rattle around in the fluid it's in. Easiest way is a punch thrown in a way that would hit a target on the chin. The force required must be superior than the target resisting it. Sucker punches are especially effective because they turn the head when the target doesn't see it-so they don't brace against it. Boxers have trouble doing it because the target should be tucking their chin.
To do it as easy as in a movie, a righty can use a left uppercut (upward fist strike) to hit a target in the head to force the chin up, followed by a fast right hook (punch sent from your right side thru target's chin to your left side). This does work and is very fast (less than 2 seconds to put someone down) if you're accurate and have mediocre force. |

I wouldn't say it's easy, but there are several sweet spots on the skull that, when hit with sufficient force, is almost guaranteed to cause unconsciousness.
I would suggest the upper part of the jaw bone or the temple. Both places are connected to the brain stem through nerves and/or arteries. A punch here will cause the force to reach your brain and shut you down.
I also believe that it's an important factor whether you expect the punch or it lands like a lightning from a blue sky. The latter are by far the worst. You'll almost certainly wake up surrounded by panicked individuals with a severely swollen head and no clue as to what happened ... then you throw up.

The studies mentioned by the Quora poster might be any of the [many studies](http://www.seas.upenn.edu/~injury/Publications.html#Head) that came out of the Head Injury Laboratory at the University of Pennsylvania, but is most likely referring (primarily) to "[Physical model simulations of brain injury in the primate](http://www.ncbi.nlm.nih.gov/pubmed/2384494)", by Margulies SS, Thibault LE, and Gennarelli TA (published in the Journal of Biomechanics in 1990). | Yes it is and there are multiple evidence of that on youtube, like these:
,
There are two things worth mentioning though: 1. It takes a lot of practice to be able to do that. 2. It is hard to control the damage that you are causing by these knock outs. People die from getting punched in the skull/falling/etc. |
