Facebook Goes To 64 Bit User IDs

Zonk posted more than 6 years ago | from the internet-users-on-mars-or-europa-can-expect-to-sign-up-soon dept.

It's funny.  Laugh. 144

NewsCloud writes "Facebook has announced to developers that they are moving to a 64 bit user ID in November. At 32 bits, the current ID allows nearly 4.3 billion user accounts. Yet, despite having only 47 million users today, Facebook's move to 64 bits will allow it to have more than 18 quintillion (18,446,744,074,000,000,000) user accounts. Of course, there are currently only about 6.5 billion people in the world. Is Facebook setting their sights beyond Earth or just trying to avoid what happened when Slashdot ran out of space for comment IDs last year. Perhaps they are planning to implement personas."

getting pussy goes 64 bit! (-1, Offtopic)

Anonymous Coward | more than 6 years ago | (#21060071)


In today's society, it is relatively easy to get laid, but it does always help when you have a GAME-PLAN! This is what I am about to offer you, A planned way to get your prick into a female's vagina (cunt). Getting a woman to willingly drop her pants for you is not what would be classified as an easy task, but the ultimate result of a warm and wet pussy snugly wrapped around your throbbing cock is certainly well worth your most earnest effort! First, Don't bother trying to go after the most popular or the best looking female in your life! That Bitch already has every stud in the world trying to BANG her... Search out a plain looking female who looks like she would be flattered by attention... This does NOT mean to pick a female who is not worthy of your attention. The selection of the TARGETED female is your initial step in the procedure!


Your selected Bitch should possess the following traits: She should have an out going personality, a friendly smile and fairly large tits! She should be very limited in The Dating Game, and she should not have a current boyfriend. After all, this isn't a lesson on how to pick up a Bimbo or a common whore! This is a lesson on how to PREY on a young and innocent female! You now want to show an interest in this female. Start out by smiling at her when-ever you see her... After a few days, if you don't already know what her name is, BUMP into her by accident, and act embarrassed, but keep smiling at her when you do this... Then take this opportunity to introduce yourself to her by exchanging names, and be sure to compliment her that 'She is one of the most attractive females that you have seen in months!' and it just so happens you have common interests! (CHEAT! Find out one of her interests and study up on it!) After all, this is the female that you have decided that you want to FUCK! Now start SWEET TALKING your target! Mention to her that you heard that she is also interested in WHATEVER! She will jump at this chance, unless you are a FUCKING DORK, and then you should have gone after the DOG that looked she should be BARKING AT THE MOON!


At this point, you should already be sending out sexual signs to let the female know her mind and brains are NOT your only interest! Look down at her tits WHILE you are talking to her. DO NOT GAWK AT THEM, but simply let her know that you've noticed that she has a PRETTY decent set of tits! If she is still receptive of your advances, you are already 20% there!! It is now time to BACK OFF !! You have accomplished your first step in your journey toward Sexual gratification! She will need a day or two to digest your encounter. With any LUCK, she will have bragged to a few of her friends about you. This will REALLY put the final nail in her Vaginal coffin, and make her an extremely easy target! When ever you see her, keep smiling, and keep letting her know that you are STILL very interested in her. If you have a chance to chat with her, REMEMBER to pay her compliments like 'How PRETTY her hair looks, or what a LOVELY dress she is wearing, or how INTOXICATING her perfume is! It is now time to move in on your prey like a frigging MAD dog in HEAT!!


It is now time to turn on your charms. You should be acting friendlier and certainly more aggressive toward her as each day and hour passes. It is now time to ask her out on a date that will involve your MUTUAL interest. (Let the scenario be that you both enjoy going to the movies.) This part takes some BALLS, but if you want to get laid, you gotta DO IT! Ask her to go to that movie with you! You will have to pay her way. The first date should be nothing more than holding hands in the movies and maybe an occasional kiss. Unless she takes the initiative, DO NOT attempt to sexually molest her, not yet anyway! After your FIRST date has ended, make it a point to let her know what a GREAT time you had being with her, and set up another date in a few days.. (This will again give her time to BRAG to her girl friends about the WONDERFUL guy she has started to date!) She is now to falling into the 'PEANUT BUTTER LEGS' (Easy to spread) trap! Your GETTING LAID game plan is now 40% complete! It is now time to start the physical assault of the Bitch that you have targeted!


To begin your physical assault of your chosen female! You must realize that you simply can not rip off her clothing and just FUCK her! It must be done with a smooth and sophisticated technique... It is now mandatory that you relate to this female that you care DEEPLY about her! You must make her feel that she is the ONLY female in the world that you have any genuine feelings for... Once she believes that, ANYTHING is possible!! The next step is to lure her into your apartment when nobody else is home. If this is not possible, get her in a car and drive to a secluded area. If there are no secluded areas, or lover's lanes in your neighborhood, try the back of the Cemetery or in back of an empty warehouse or even in a vacant garage. You have now arrived at the CRUCIAL point where this female must be reassured that she is 'THE SPECIAL GIRL IN YOUR LIFE' (At least for this evening!) It is now the proper time for your Sexual Assault on her to begin! Foreplay is the most crucial and final step in your master Game Plan! It requires gentleness, and the understanding of her inner fears. Unless you have selected a totally clueless bitch, she has some idea of the situation that she is about to get herself into. Also, keep in mind that females enjoy sexual stimulation as much as males, so you will actually be doing her a favor, if you do it right! It must be pleasurable for her, or she may decide to reject your advances! Look this female directly in the eyes, smile slightly and tell her that she has the most beautiful eyes that you have ever looked into! Before she can reply to your compliment, reach out and stroke her hair. Again smile and tell her how soft and lovely her hair is. While you have your hand on her hair, tell her how sensuous her lips are. At the same moment, curl your outstretched hand around the back of her neck, and pull her face toward yours. Next, give her a tender kiss in the lips. Do not make it last for more than two seconds. Look directly into her eyes, tenderly smile at her, and again kiss her, but this time make it last for about 10 seconds, and do it with a bit more passion.


Reassure her that you care very much about her, and her feelings. This part is extremely crucial! Most of all make DAMN sure that she understands that you RESPECT her! If she falls for that line of SHIT, you are about 60% there! In order for you to receive pleasure from a female, you must first give her pleasure! Tenderly take this female into your arms and gently hug her. While you are hugging her, put your head on her shoulder so your mouth is near the side of her neck. Next start to gently kiss the side of her neck. Move your mouth slightly after each kiss, but continue to work in the same general area for about one full minute. This action will send shivers of excitement through her whole body. At this point you should once again kiss her on the lips. As you kiss her, gently slide your hands to her back and with your fingers spread wide apart, firmly pull her body toward yours, as you slightly massage her and relax her. Rub her shoulders, the back of her neck, and the lower sides of her back. Continue these actions, as you continue to kiss and caress the Bitch. While you are kissing her neck, take a moment to take a deep breath and gently breath into her ear. (DO NOT BLOW INTO IT, JUST BREATH INTO IT!) This will arouse her PASSION and get her FEMALE SEX JUICES flowing!


At the first moment that you notice her mouth opening slightly while you are kissing her, slide your tongue into her mouth and move it around her tongue, and begin to kiss her slightly harder. Start to breath slightly harder to let her know that she has started to get you excited! As you play kissy tongue, slide one of your hands onto her chest, and very gently rub it across her tit! She should not have any objection at this point. Keep deeply kissing her and slide the other hand onto her other tit. Begin to gently message her tits in a circular motion, while you also gently squeeze them. Remember, you are not milking a friggin' cow; you are seducing a female! It is now time for you to start upwrapping (undressing) your sexual like unbuttoning your own shirt with one hand, days before this event takes place. Before you take the Bitch to the secluded area, you should make mental notes of the type of blouse, dress, pants, nylons etc. that she is wearing. Remember where the zippers are; see if her blouse buttons are in the front or the back. If she is wearing a sweater, you may have to slide your hands underneath it.


If your selected Bitch is allowing you to fondle her tits through her clothing she will also allow you undress her to the point that you can play with them she is naked from the waist up. To do this, you must first carefully unbutton her blouse or even assist her in removing her sweater. Next you will be faced with removing her bra. Some of these little suckers can be tricky! Most bras are hooked in the rear. The larger the tits, the more hooks you'll find! If you put your finger on one side of the hook and your thumb on the other side then squeeze, the hook can be undone with one careful that you don't tear any of her clothes, because her mother or father might figure out what you have done to their daughter, and that could lead to you receiving a severe beating! Unless the Bitch helps you to totally remove the bra, don't bother trying to get it all the way off. Once the hooks are undone, you can slip your hands beyond her stomach, up to her tits, and fondle to your heart's desire! Next, it is time to start sucking on her nipples! This causes a wonderful sensation in a female's body it actually activates her 'I WANT MORE' button! Naturally, after 5 or 10 minutes of this TIT action, you will be happy to oblige her!


Do not just suck on her nipples. Move your tongue around it also. Foreplay is a body massage done with your hands, fingers and tongue. The entire intent of this exercise is to arouse the Bitch's sexual excitement... At some point during your sexual attack, you may encounter some resistance. The Bitch may say something like 'PLEASE STOP!' This is a simple ploy used by many females, because they don't want you to think that they are a tramp! Ignore those stupid requests. You might consider putting her at ease saying that you promise not to go any further than you have already gone. (Lie to the Bitch! Tell her that you er h her! Tell her WHATEVER she wants to hear!) Continue to kiss her, lick her, hold her, squeeze her, rub her, suck on her nipples and fondle her... Continue your sensual and sexual body massage... There is a wonderful mechanism built into all females! It is an audible report of the progress of your assault. Listen for her to start breathing HEAVILY! This means that her defenses are weakening and her body is now ready for the next step of your Game Plan! You are now ready to attack her most private area! It is time to direct your efforts and energy to getting your hand into her pants, so you can start rubbing her cunt!


Before you can get at her cunt, you must continue to undress the Bitch. This is a CRITICAL moment, because fear and panic may arise when she realizes just how far she has already allowed you to proceed! You must overcome any and all her objections at this point or ALL of your efforts will be lost! You may have to promise the Bitch that you will not go 'ALL THE WAY!' You just want to make her feel GOOD because you CARE about her and you er h her, and be sure to let her know that if she cares about you, she will let you rub her between her legs! When you first begin to rub her pussy, it should be done over her clothing, until the sensation of sexual bliss begins to further enhance her physical joy. Her breathing will become noticeably increased and she will reach the point where she will start to make moaning sounds. You should still be kissing, hugging and rubbing her while you start to loosen her pants. Assuming that the Bitch is breathing very heavily, and is now in FULL heat, you should be able to unbutton or unzip her lower garments so you can make enough room so you can comfortably slide your hand between her legs. First, gently, then firmly rub the hairy area above her cunt!


You have now reached another crucial point in your molestation of the Bitch. There are two ways to rub a cunt: The RIGHT way and The WRONG way. If you do it the wrong way, and it is not satisfying to her, or even worse, if you cause her any pain, you can TOTALLY forget about getting laid! The very first step is to get her legs spread far enough apart so that her cunt is accessible to your hand. Curl your hand into a fist with your middle finger sticking out and reach down between her legs and gently slide it upward. Doing this will accomplish several different things. First, it will separate her cunt hairs. If you don't get them separated, it will be painful for the Bitch, so make sure you do it enough times so that your finger slides smoothly from the bottom to the top of her cunt. It will also open her cunt lips, and it will expose her clitoris (clit) so that you can start to rub it. As your finger travels from the bottom of her cunt lips to the top, you will notice two things. First her cunt will be wet. Second at the top of her cunt lips there will be a piece of skin that slightly hangs out or may even seem a little bit swollen. That is her Clit! That is the magic button of her pussy! Take two fingers and slide them back down to her cunt lips and insert them just far enough into her cunt to get them wet. Now slide them back up to her clit and rub it from side to side. Do not rub it up and down! You will know when you are doing it right, because the Bitch will start to groan with extreme PLEASURE! You may also alternate by rubbing in a circular pattern. Keep in mind that the Bitch is getting close to achieving an ORGASM (Getting her rocks off). At this moment, if she hasn't already done so, take her hand and place it on your prick so that she can start to give you mutual pleasure. Be sure to whisper to her 'OH GOD! LOOK AT HOW HOT YOU HAVE MADE ME!' This will enhance her sexual and animal desires even more! Let her know just how WONDERFUL your body is beginning feel. Keep rubbing her Clit, and keep kissing and caressing entire body. The moment as soon as she finishes getting her rocks off, keep hugging and kissing her! Reassure her about how much you love her and what a wonderful experience you enjoyed with her. Do NOT let her feel guilty about it, because the BEST is about to happen! You are now going to try to FUCK this HOT little Bitch!


If you have properly followed ALL of the steps, there is no reason that the Bitch will refuse to let you FUCK her. After all, you serviced her well, and it is now time for her to repay you for what you did for her. If she hasn't already unzipped your fly and pulled your prick out, do not hesitate to do it for her. Take her hand and wrap it around your cock, and show her how to move it up and down so that it feels best for you. Do not let her rub it too much, because you will soon need it for BIGGER and BETTER things. While the Bitch is rubbing your cock, you should be rubbing and squeezing her tits, and again rubbing her pussy. By now, her clit is very sensitive, so you should now insert one finger directly into her cunt and concentrate on an area often referred to as the 'G' spot. It is inside her pussy and since pussies are like snow flakes (no two are alike) the 'G' spot can be located almost anywhere inside. You will need the Bitch to inform you when you have located her inner button.


It is now time for your reward if you followed your game plan properly! By now this Bitch should be BEGGING to get fucked, but if she isn't, do not dismay! It doesn't mean that you won't get laid, it just means that you may have to use a few TRICKS of the trade to get what you want from her. You should now have the Bitch totally undressed from her waist down. This means that her pants, pantihose and undies should be totally off of her body! If she objects to this simply assure her that this Many younger females have an extremely tight pussy, so the SECRET to being able insert your cock into her is LUBRICATION! Most inexperienced females are afraid of having their cunt soaked with things like baby oil, so the next best item that you have is your spit. While you are hugging her with one of your arms, discreetly put as much spit as you can onto the fingers of your other hand, and smear it all over her cunt. Get her pussy as juicy as you can, so that penetration will not be a problem. The next and final step is really easier that you would think. Simply hug the Bitch and pull her as close to you as you can. Make sure that you slide your leg between her legs as you do this. Your body should now be laying directly on top of her. Without any hesitation, you should slide your other leg between her legs, and spread hers far apart! Now is the EXACT time to lunge your cock forward toward her warm and wet hole! You probably will have to direct your cock with your hand until you find the opening of her gash. Just move your cock up and of the way in! By now, the Bitch may object to getting fucked, but there is nothing she can do or say about it. To alleviate her from having a panic attack, simply assure her that you PROMISE not to CUM inside of her. Help her to forget her fears. Ask her about how GOOD her pussy is feeling. Ask the Bitch if you are humping her too hard. Keep the humping rhythm going at a pace that she seems to enjoy. If she is not humping back, simply slide your hand under her ass and pull her toward you each time you thrust forward into her. She will soon understand what she should be doing to mutually please and satisfy both you and her. Remember that a woman's cunt gives her the same amount of PLEASURE that a prick gives a guy, so sensual pleasures are received by both you and the Bitch.


Fucking a woman properly is a complicated process. It is much more complex than just shoving your cock in and out of her cunt until you blow your load! If you fuck a woman properly, she will BEG for it again and again. You can turn a Bitch into your personal sex slave once you have mastered the art of sexually satisfying a female. The most important asset that you can use when you are fucking a Bitch is 'CONTROL'. Your prick rubbing inside of her cunt will give the female an orgasm as strong and powerful as a male! Believe it! If you stuff your prick into some Bitch's pussy and blow your load in thirty seconds, I can guarantee you that you will never fuck that Bitch again unless she has recently had Electrical shock treatments. The secret to fucking a Bitch properly is simply to keep humping, fondling, and kissing her until she CUMS! Yup! Broads CUM too, just like guys, but they can CUM more than once! If you keep fucking a Bitch, she will CUM three, four or five times! It may take her a couple of minutes between each orgasm, but it WILL happen if you keep fucking her! If the word 'CONTROL' comes into play.


Control simply means preventing yourself from CUMMING. It isn't easy. But it can be accomplished by two different methods. The first method is physical. When you start to get the feeling that you are about to CUM, you should FORCE yourself like you are trying to PISS. It isn't easy, but it works. Your prick is HARD so you won't be able to piss, but the bodily function of straining to piss will send a message to your BALLS that you don't to 'SHOOT YOUR WAD' yet. The second method to prevent you from CUMMING is mental. This means that you have to STOP thinking about what you are doing, and think about something that has NOTHING to do with sex. Think about a problem or some situation that you are currently dealing with. Get your mind off of the fact that you are having sex because it will only excite you, and that will make you cum. CONTROL is the 'SEXUAL SECRET' to being THE GUY that every Bitch wants to LAY! Once you have mastered this technique, you will DESIRED by every Bitch who has heard about your STAYING powers, and believe me, Bitches do gossip about shit like this, so your sexual reputation will rapidly grow!


You are now humping and thumping your Bitch. She has CUM several times and it is now time for you to 'BLOW YOUR LOAD', but you must first ask the Bitch if she is currently taking Birth Control pills. If she is, Go for IT!!!

Re:Network ID (3, Insightful)

Tablizer (95088) | more than 6 years ago | (#21060127)

Why did they used to make part of the ID be a network identifier? What if you need to move users to other networks? I can perhaps see how it could make it possible to assign unique id's without central communication by making blocks of numbers to be pre-assigned by different regions, etc. But as a direct network allocator, it seems problematic.

And why we are on the topic of ID's, why are Microsoft product ID's so damned long? They use letters, which gives them 35-base number set (including the digits, excluding "o") which in theory would mean you don't need long strings. Is this to reduce trial-and-error loop hacking? It seems like it would make for a lot of help-desk calls because the chances of mistyping is large.

So basically facebook changed there maximum users from a huge number to an even bigger number.

The difference being that the current (huge) number was not quite sufficient to register all human beings on the planet, so we have to wonder why they did this. 32-bit integers are kind of the default, so most people wouldn't worry about it. So why are they doing this?

If you look, this article is filed under "It's funny. Laugh." And it is, really. Either Facebook is doing this for no good reason, or someone actually has some justification for going to the time and expense to change their database in this way. And so... Are they really planning on registering more human beings that exist?

I realize it's not funny to you now, as you've had to have the joke explained to you...

Are we going to post a news story everytime google adds to their storage system?

If they suddenly went from 2 gigs of email to 5 exabytes, then yes.

Also, keep in mind that Slashdot did cover when Gmail was first released with that 2 gigs, which seemed impossibly huge, and was at least one or two orders of magnitude larger than their closest competitor.

Why would you possibly want to use 33, or 39 bits, when you can simply set it to "64-bit" that is easily supported by your compilers and 64-bit hardware on your servers? It's not like the numbers will take less computation or less storage because they're less than 64-bits: storing digital numbers doesn't work that way.

I seem to remember an article poking fun at the fact google's email space isn't "infinite" like some other services so if they doubled or tripled their limit I guess it would be on the front page.

or microsoft adds another bloated line of code?
Windows Vista articles?

or everytime the telco's build a tower?
articles about the irrational fear of wifi and the "dangers" of cell phone towers, I believe we've seen that too. so yes, there will be a front page article on slashdot about all three of these.

Not just user IDs (5, Interesting)

digital bath (650895) | more than 6 years ago | (#21060253)

TFA says nothing specific to 'user ids' - it says object ids in general. I assume this includes things like comment ids, event ids, etc - which makes overflowing the 32 bit limit much more reasonable.

It does actually "Up until this point, all of our user IDs have been small enough that 32 bits is sufficient to store them all. In the not-so-distant future, we will begin using 64 bit object IDs in some places. So, the numbers will become to big to handle in some situations" The wording is actually pretty shocking so it could well be that the userid's are being made 64 bit but comments etc. are, or it could be they are making userid's 64 bit also.

Seems pretty clear:
1. User IDs are currently 32 bits.
2. They are changing some object IDs to 64 bits.
It does not say they are changing user IDs to 64 bits. It's implied but not stated. It's not actually clear that "user ID" means the ID of an account - it might just mean a user-visible ID (such as comments have on Slashdot).

Re:Not just user IDs (3, Insightful)

jd (1658) | more than 6 years ago | (#21060895)

My interpretation (which is just as invalid as everyone else's, Facebook included) would be that they are abolishing UserIDs altogether and switching to a 64-bit universal ID. That kinda makes sense, as it would make defining relationships between any two types of object easy.

No Reuse... (1)

Frosty Piss (770223) | more than 6 years ago | (#21060257)

Probably just means they don't have to worry about needing to reuse IDs of inactive accounts...

32 bit constraint kind of forces a big leap (4, Informative)

istartedi (132515) | more than 6 years ago | (#21060261)

If you think you might ever have more than 2^32 of something, you kind of have to go to 2^64. Yes. It's an obscene ammount of possibilities; but it's the next biggest size. You really don't have much of a choice here. You could implement 5-byte numbers, but it'd be a PiTA. No CPUs have native 5-byte ints. The progression has always been a doubling of int size.

If that doesn't make sense, you shouldn't be on Slashdot. Maybe you should be someplace else... like Facebook maybe?

Re:32 bit constraint kind of forces a big leap (1)

Howzer (580315) | more than 6 years ago | (#21060471)

>>but it's the next biggest size

Ah, no, it isn't. Just as an example, right off the top of my head, they could go from 32 bits to 34 bits, giving them an extra 12,884,901,888 ids. Or 2 for every person on the planet.

Or they could round it off at a nice 40, for a healthy 1,099,511,627,776 -- roughly a trillion users.

There is absolutely no rule that says "need bigger than 32 bit -- must choose 64 bit".

Re:32 bit constraint kind of forces a big leap (1)

istartedi (132515) | more than 6 years ago | (#21060541)

True, there is no rule that says you must choose the next native integer size. I addressed that in my OP with an example. I think maybe you're just trying to be difficult here. Perhaps I should have said explicitly that it's the next largest native int, and the next largest practical size because you don't have to use a special library to support it on a 64-bit CPU. I expect people to "get it". Maybe that was asking too much; or like I said, maybe you're just trying to be difficult. Meh.

Facebook uses PostgreSQL as a backend, not MySQL, and PostgreSQL doesn't have a 48-bit datatype, so in their case it's either 32-bit or 64-bit.

You use 'always' in a non-standard way. There were 36 and 60 bit processors available amongst others. 64 doesn't have to be the next number for processing. As someone else said 32->64 is due to postgreSQL. That, and the youngsters don't know any better. DB space is made by elves.

I can see a few reasons (5, Insightful)

Jay L (74152) | more than 6 years ago | (#21060363)

Even it if it's just user IDs, and not object IDs as another user posted...

* 64-bit user IDs are easier to partition. They could be using the top N bits as a database ID.

* They may want to allocate the IDs randomly instead of sequentially. 64-bit IDs would involve fewer collisions.

* We don't know what their account churn rate is; if people sign up, forget, and create new accounts again frequently, they could have many more than 47 million dormant accounts sitting around.

A 32-bit ID really does get cramped when you have a large user base.

Re:I can see a few reasons (1)

c_forq (924234) | more than 6 years ago | (#21060861)

The other thing that shocks me that people haven't commented on yet is that maybe Facebook is looking long term. It doesn't seem to be going away anytime soon, and appears to still be growing. Sure there are only 6 billion people now, but in 100 years those 6 billion people will be replaced.

wfberg (24378) | more than 6 years ago | (#21061747)

As another site usually puts it "the real WTF is..." that they don't use 128 bit identifiers.

If only if there was some sort of, I don't know, scheme for identifiers that has approximately 2^122 possible values, fits in 128 bits, has a standard notation and is supported by major databases as an 'auto increment' field.. With that many values, you could almost assume that using some sort of randomized value is bound to be unique - perhaps even universally unique. You could call it Globally Unique IDentifier (GUID) or UUID, I guess.

Kaz Kylheku (1484) | more than 6 years ago | (#21060621)

Not all of the bits of an ID are necessarily there for uniqueness. Wider ID's allow for features such as check digits (being able to tell whether an ID is valid without doing an existence query in a remote database) and other information. Namely, various immutable properties of the object that is denoted by the ID can be stored in the ID itself. This is similar to using spare bits within a machine address for tagging an object with a type or other attribute. It may be very useful to be able to tell something about an object just from the ID alone.

What about population growth? Surely current number of users is much less than 2^32, but number of possible users is not number of people in the world at this time. Imagine that the world has exactly 2^32 inhabitants and everyone has a facebook account. What would you do with new-borns? Will you reuse accounts?

There is difference between user accounts and active user accounts. Number of active user accounts can not be larger than actual population of the world, if we consider maximum of one account per user. However, total number of accounts in history can be much much larger.

My guess: Security, segementation, multiple log in (2, Interesting)

drolli (522659) | more than 6 years ago | (#21061051)

-you can harden your security by populating the user-id space sparsely. Somebody who is guessing for an user id will have an hard time.

-It can make things easier to have your user groups organized according to geographic location, company issuing th id (e.g. local branch), etc.

-Multiple log ins. Who knows. maybe it is easier to associate internally several uids with each uid (could make things more static).

So let's say:

10 bit for segmentation
20 for checksumming
4 for multiple logins

leaves only 29 bit as payload
