Maybe it will fix the USB hot plug problem.

Maybe it will fix the residential CE/FCC compliance issue.

no actual information available.

There seems to be a pattern that new hardware revisions are released shortly after JamesH says they won't be.

 

Model A's planned for March.

    If the Model A is planned for March 2013, then RPF's banner headline will have declared the Pi as the $25 computer for a whole year by then.  Isn't there a law against such blatant long-term false advertising?

    coder27 is being gamesome.  The link is to a 20 Feb 2012 comment where liz promises that "you'll definitely be able to buy Model As in March".  True, she doesn't specify the year.

    You can't have it both ways.  If Broadcom's capacity is all contracted out, and the people they contract out to have LOTS of capacity, and will make whatever Broadcom asks, then Broadcom's inability to produce SoCs at a higher rate and with less lead time is even less comprehensible.  Third parties would be falling over themselves to manufacture more BCM2835 for Broadcom given the demand for Pi worldwide, because "LOTS of capacity" that is twiddling its thumbs is very costly.

     

    That doesn't seem to be what is happening here.  Admittedly we're speculating, but some things look more likely than others, and a surplus of capacity on which to produce BCM2835 seems extraordinarily unlikely.

     

    And that is where the ball returns to my court.  Fabs don't want to handle excess storage (of finished product) either.  So they won't keep a high capacity either (I was quite surprised to hear that B-com did not directly fab the chip themselves though).  You're logic is backwards though, the fact they don't have their own fab facility will actually increases turn around time as they become a middleman (so to speak) in the process.  They are bound by the fab's schedule which means they really can't adjust an order at the last minute.  Which again brings us full circle to the fact that it is the responsibility of the customer to appropriately plan for the demand of a product in accordance with the suppliers schedule. It should also be noted, again, that the pi is not some big ticket item so no, fabs will not be falling over themselves to manufacture the chip.  Besides, I'm willing to bet that B-com has some very specific NDAs and contracts that prevent them from doing just that in exchange for good deals.

     

    And you really got to get the idea that not making the BCM2835 = wasted time or a waste of capacity.  Fab plants will build no more and no less than what has been ordered.  Any time they're not making the BCM2835, they're making other chips.  Fab facilities wait for no one!  Which makes more sense to you?  Fill a big order for a customer to meet deadlines, or building some extra low cost chips in the eventuality that a customer might want some more of it before the next run?  That a waste of time material and storage space, plus the fab facility has no guarantees that the chip will still be in demand in the future.  As much as I like the pi, it could flop at any minute.  People could get tired of the USB issues, or decide they'd rather pay double and get a little bit faster android device for their media center needs.  It's insanely bad business for a fab facility to make an excess of a product that the customer hasn't ordered rather than moving things onto filling the next product that has a customer waiting right now to purchase it.

    However, you prefer to place the blame on RS and somehow twist it to look as if an order placed by RS could magically create new fabrication capacity at Broadcom.  It can't.  At most it can affect scheduling of what is fabricated on capacity-limited equipment so that RS's devices get manufactured before those of another customer.  The restricted fabrication capacity remains restricted though, whether it is producing devices for RS or for someone else.  An order won't bring a new fabrication plant online, that costs billions.  It is accurate to state (assuming of course that our speculation is correct) that Broadcom's lack of spare capacity is the limiting factor.

     

    Aye yi yi, you just really don't get the way this works do you?  Turns out the explanation I typed up explaining how fab plants worked was far too complicated and long so it got trashed. I'll go from this approach.  RS had problems Farnell didn't.  If they had both had problems and the roku to boot than I'd be with you 100%!  If it worked the way you're suggesting it does than everyone would have issues equally.  Or at best it would rotate as each distributor got their share of limited capacity chip.  First RS would be short on supplies, then Farnell (then Roku).  Since this has obviously has not been the case, and since Billy has enlightened us that B-com is fabless and capacity would not be an issue for a company whose whole business model is getting the chips that have been ordered in the time frame they have been contractually limited to, then all signs indicate that the issue at hand was Farnell ordered enough to meet demand, Roku ordered enough to meet demand, and RS thought the Pi wouldn't be as successful as it has been and ordered a smaller quantity than Farnell.

    ... And remember, there is a 30wk (still don't [believe] that one) lead time - that's over 6 months, a lot can happen in 6 months...

    The source on the 30 week lead time is liz herself.  Last September (2012) I heard Rob Bishop say 23 weeks, so it's gotten worse.  As you say, >6 months is a long time and fads can be short-lived.  For example, Richard Lester made A Hard Day's Night (1964) on a very short schedule since nobody knew how long the Beatles would be popular image  So I can see why neither distributor would want to be stuck with unsellable BCM2835 inventory.

     

    Interesting that the fab times are getting worse.  Maybe it's Apple booking up prime fab time so they can peevishly distance themselves further from Samsung.  Or the fabs are swamped making Allwinner A10s and A13s.

    Used to work in the industry - times vary according to what's popular - probably new models of phone coming out soon - Christmas tends to cause a rush of new product hitting the market, so the fabs will be backed up which would result in longer lead times. Probably not Apple, although their production is moving away from Samsung, so might be going to TSMC or similar. The sort of volume there would dwarf the raspberry pi, so it's not surprising that's backed up. If I were a manufacturer I'd be building the high profit chips, not low profit stuff like the 2835 (or the Allwinners, but they would be in Chinese fabs anyway). Which is exactly what is happening.

    According to this Allwinner press release, the A10 is manufactured by TSMC, one of the fabs used by Broadcom.  So lots of competition for a limited amount of fab.

    That's not consistent with Billy's "the people they contract out to have LOTS of capacity, and will make whatever you ask".  Which is it, lots of capacity allowing Broadcom to enjoy a buyer's market, or very restricted capacity making fabrication a seller's market and giving Broadcom little to no options?

     

    You're both attempting to substantiate the same conclusion from incompatible premises, so one of you is clearly wrong.  Even if each were true separately, they can't both be true simultaneously.

     

    In addition to one of you being necessarily wrong, you're both making out that Broadcom's business planners are incompetent at capitalizing on a massive demand for one of their chips, and that suggests strongly that you're both wrong.  I may not like Broadcom's secrecy practices, but I see no sign that they are incompetent at getting devices made cheaply and in vast numbers, under either of your premises.  If they could make money from this insatiable demand, they would, even if the profit is less than when producing other devices.  It's still profitable for them, and nobody has suggested otherwise (yet).

     

    By Occam's Razor, the fact that they aren't making money from it at the rate for which there is demand suggests that they can't do so, because competent business people (which I believe they are) would find a way if it were at all possible.  They've had since the start of March to fully realize the scale of demand and react to it in a way that would capitalize on the world's hunger for an old chip on which their investment has already been recouped, so it's all straight profit.  I do not think they would look this gift horse in the mouth.

     

    So, you'll have to find a much stronger reason for the company's apparent inability to knock out large numbers of these SoCs than you have so far to be convincing.  They're not some 2-bit outfit like you make them out to be.  To suggest that they  ignored one half of this zero-risk profit stream because they got no order from RS is quite comical.

    I have bought three Raspberry PI's.

     

    The longest I had to wait was 3 weeks for one purchased from Allied Electronics. Original delivery was given as 6 to 8 weeks.

    While waiting for Allied, Element 14 advertised a 7 day wait so I bought one from them and it was delivered in 3 to 4 days.

    When the 512MB version was announced I bought another one from Element 14 that was also delivered in 3 to 4 days.

     

    When actual availability of the Raspberry Pi was first announced I signed up with RS to be notified when I could order one

    from them the next day (couldn't get anything done on the first day because the web site was totally slashdoted). To this

    day I am still waiting for that notification. In every web post I've read were some one has been waiting months for delivery

    and the name of the company they ordered from was mentioned it was RS.

     

    Most fabs usually have many customers. Some of the customers, like Broadcom have more than one type of device being

    made. Each customer has a contract for a certain number of all the devices it wants that the fab is expected to produce. If

    a fab is running at or near full capacity as you correctly say they try really hard to do they can't just magically turn on "more

    capacity" when one of their customers has a large unexpected increase in demand for one of the devices. Unless other

    customer(s) can reduce their needs, more time to adjust doesn't help either. Going to another fab to produce the device

    requires at least a 6 to 8 month time frame assuming of course you can find one with unused capacity that supports a

    compatable fabrication process and the tools you used to design the device.

     

    As for Broadcoms secrecy practices, they are not much different from all of the other ARM SOC sellers. There is enough

    information for most of the peripherals to write drivers for them. Graphics accelerators, multimedia accelerators, and DSPs

    tend to be the most highly garded because in many cases the IP for them is actually from another company and they are

    under a NDA to not release it. In some cases they may just be trying to not get sued for real or imagined (as in troll) patent

    violations. Finally, and what I consider the worst reason is for some perceived competitive advantage. As demand for ARM

    SOCs increase this veil of secrecy is slowly being lifted. Just a couple of days ago I read about a rumor that the PowerVR

    graphics accelerator was going to get oficial support for an open source driver. I have also read that there is official support

    from for an open source driver for the Mali graphics accelerator although I have not been able to find it with Google.

    Morgaine.

     

    *sigh* let's start from the top of your statement.  First you're trying to juxtapose mine and Billy's statements and make them about the same thing when its not.  First you have Billy's statement which is to prove that the issue is not a matter of a lack of capacity to produce the chips.  Your argument has been that B-com lacks the ability to meet the demand of the chip because they cannot produce the chip fast enough, to which Billy has responded that no, they outsource their production to other places, places which can more than meet the demand of any quantity of chips you so desire.

     

    To which you made the response that a higher capacity would by default create shorter response times.  To which I responded no, since they're outsourcing the work it means you'd actually have longer wait times.  Or perhaps a better way of saying that is you have consistent wait times.  You get your shipment every X weeks and you prioritise your fab time to make you the most profit while still meeting customer demand.  Ergo their big money makes would have shorter turn around times and their 1/1000 of a percent of a quarterly earnings chip get's LONG wait times.  You tell your customers up front what the wait time for a product is and the customer orders the amount of product they believe they will need to carry them from one shipment to another.  This is the foundation of a business model.  You try to get enough raw material to meet demand until the next shipment of raw material comes in.  It's been that way with every job I worked with right down to Baskin Robbins.  If we ran out of Vanilla ice cream because we didn't ordered enough the corporate office didn't rush us an extra shippment at a higher price to keep getting that Vanilla revenue.  We had to make do with our poor planning.

     

    You can't just cherry pick statements out of context to try and support your complete lack of experience in this field with two people experienced in their respective areas. 

     

    As for the necessity of one of us being wrong... that would only be correct if your basic underlying assumptions were correct, but unfortunately they are not as anyone who has worked in these lines of work can tell you.  Your line of reasoning would make sense if the chip being discussed was the breadwinner of B-com.  As I stated in an earlier post even if all $35 dollars the pi costs went to B-com, the entire sales of the pi for the whole year wouldn't equal but a hundredth of a percent of the earning b-com made for a quarter.  (based off a Q4 1.82 Billion listed earnings in 2011 on their site).  Of course the reality is I'd be shocked if they even made 5 dollars off every sale of the pi for their chip, ergo the pi sales for a full year represents something in the 1/1000th of a percentage of a lower than usual quarter.

     

    I will agree with you on one fact, and that is that I too believe that they are competent business people, which is why they order only a quantity of such a low revenue chip in exact proportion with what has been ordered.  You try not to overstock on your breadwinners let alone some outdated chip like the BCM2835.  And no, there's no such thing as a zero-risk profit stream.  You're using the wonderful thing called hindsight to see that the pi has been somewhat successful and trying to apply that as common knowledge foresight to the people who ordered the chips months ago.  It just doesn't work that way.  Farnell and RS both ordered chips based off how successful they thought the pi was going to be.  All signs indicate that RS didn't think it would be this successful while Farnell took a risk and invested the cash to give this pi thing a whirl.  Obviously this has worked well for Farnell.

     

    And again, your line of logic that B-com can't build chips quickly enough to meet demand would only work if both RS, Farnell and Roku (well maybe not Roku, but Farnell and RS) experienced equal shortages or if they had rolling shortages with each company have a period where they don't have enough to meet demand but the other company does.  This just hasn't been the case so it doesn't hold up.

    I'm afraid we're not going to get anywhere in this discussion if you insist on reasoning that if a company has more fabrication capacity available to it through a buoyant fabrication sector then this implies that it will have longer wait times.  That's not logical, Sir.

     

    When there are many parties able to provide a service then your wait times are inherently shorter because for any given amount of fabrication load in the sector, that load is spread over more fab providers with less queueing, and when you are tendering for service then naturally lead times are one important bargaining point over which there will be competition.  You can expect the average lead times to be lower in a buoyant sector with many providers, not longer.

     

    Now if you want to argue that it's not that simple because different fab providers deal with different technologies then of course I would have to agree with you, it will inevitably reduce the set of providers which a given fabless manufacturer can utilize, but that wasn't what you claimed as far as I can discern.

     

    Our most important point of disagreement isn't really that though.  It's that you seem to insist that it makes perfect sense for Broadcom to do nothing about assisting the non-stop manufacture of BCM2835 devices despite knowing since March the overall levels of interest, despite having an inside route into per-partner demand information through RPF, despite knowing that every chip manufactured in the current months will be sold because solid order queues exist for them, and despite being able to discuss the Foundation's 2013 plans with Eben Upton owing to RPF's intimate interdependency with Broadcom to ensure that there are no surprises ahead.

     

    Instead of noting these special circumstances which create an effectively risk-free environment for BCM2835 manufacture for a certain number of months which Eben can undoubtedly quantify, you insist on treating the SoC orders as some anonymous corporate purchase request over which Broadcom has no knowledge nor control and which therefore results in an unacceptable manufacturing risk.  This just isn't so.  Pi is special.  Pi is as close to being a Broadcom product without officially being one as it gets.  The Pi alpha boards even had Broadcom's mark etched on them.  It's not some anonymous 3rd party that wants these Broadcom SoCs.  It's a family member, pretty much, and you can be confident that communications between the two parties are very close and very good.  Hindsight was not required by Broadcom, they have something far better, a direct channel to the right people and to the information they need to manufacture appropriate volumes safely.

     

    Now because you haven't done so, I'll hypothesize one theoretical risk that might exist, hypothetically.  It might be considered possible that RS would reject any faster supply of SoCs if they were produced and offered to them by Broadcom outside of contract, willing to let their customers wither of old age in the wait queue as long as they don't have to invest more than some predefined $X in Pi manufacture per quarter.  Yes it's theoretically possible, and maybe you were implying that this would constitute a real risk for Broadcom, but is it likely?  (Your allusions to risk did not make the sources of risk clear at all.)

     

    Well I really doubt that even the strongest detractor of RS would claim that there is any significant likelihood of that occurring.  I don't have any particular knowledge of RS, but even if they have some weaknesses, they are nevertheless one of those companies with a long pedigree that gets lumped into "Best of British", and the likelihood of them turning down SoCs to vanquish their backorder queue is remote, in my view, and AFAIK nobody has suggested that that is a real danger.  So from where does the risk and uncertainty that you've implied actually come?  It's really just FUD.  There can be no uncertainty nor doubt about any BCM2835 device manufactured not ending up on Pi boards and getting sold when this is done in concert with RPF as coordinator, and fearmongering about it is not helpful.

     

    Lastly, I want to address your point about how come that Farnell and Roku have not been hit with major shortages as far as we know, but RS has been.  This is the only actual numerical evidence before us whereas everything else has been speculation, even if reasoned speculation, so this is important.  Well of course I don't know, and nor do you, we can only speculate again.  We have however been speculating about it for many months here, and a number of scenarios have been suggested in the past in various threads.

     

    Deliberate under-ordering by RS despite full awareness that the length of its preorder queue would grow has of course been a leading candidate, but it was far from being the only one.  We also noted that because both manufacturers' websites collapsed when Pi was launched and remained in deep trouble for a lengthy period that spanned hours or days depending on who you asked and their location, the rate at which the two services picked up expressions of interest was more in the lap of the gods than balanced.  As a result, it's a very possible scenario that RS picked up many more registrations than Element 14 --- someone had to pick up more than the other after all.

     

    Given an initial imbalance, we then discussed here various possible scenarios under which manufactured Pi boards were allocated to the two partners.  The favoured "equal numbers to both" scenario would have the consequence of  emptying the preorder queue of the partner with the shortest queue first, hence exacerbating an already bad situation.  In contrast, an allocation proportional to the length of each partner's preorder queue would empty them both in the same amount of time, but it was considered unlikely.  In other words, the partner that performed best in the chaos of the launch week and obtained the most registrations would suffer worst from the most likely allocation policy.  Well we know that the initial allocation policy from the first batch was equal numbers to each, so at least initially we know that this very thing must have occurred.  Do we know that it was RS that suffered most?  No, but it seems likely given that RS has always had the longer queue sizes.

     

    So, things are complicated, and I wouldn't rush so fast to the conclusion that RS's problems are entirely a product of their failure with ordering.  It may have all started as a product of their comparative success with registrations, at least initially.  Once their own manufacturing got under way then of course they would have exacerbated their own predicament if they under-ordered or late-ordered, and it's never been denied that that is possible.  Despite RPF's chequered history with information release, nobody here automatically rejects information released by them (at least I don't), but only if there is additional cause to view something with suspicion, and I'm not aware of any such in this case.

     

    Even if RS's problem was entirely a product of their own mis-ordering, it still doesn't eliminate the point that I was making earlier about Broadcom being a joint partner in all of this, and that the good business sense which they possess could have harnessed the extensive third party fabrication capacity that exists in the ARM ecosystem to help reduce backlogs further (not just for RS) without impacting on their more lucrative contracts, given that we've agreed that there is no shortage of external capacity.  I expect we're going to have to disagree on that because you don't want to embrace even tentatively the possibility that Broadcom's involvement with Pi is special and carries litte risk.  So be it.

    I'm afraid we're not going to get anywhere in this discussion if you insist on reasoning that if a company has more fabrication capacity available to it through a buoyant fabrication sector then this implies that it will have longer wait times.  That's not logical, Sir.

     

    When there are many parties able to provide a service then your wait times are inherently shorter because for any given amount of fabrication load in the sector, that load is spread over more fab providers with less queueing, and when you are tendering for service then naturally lead times are one important bargaining point over which there will be competition.  You can expect the average lead times to be lower in a buoyant sector with many providers, not longer.

     

    Now if you want to argue that it's not that simple because different fab providers deal with different technologies then of course I would have to agree with you, it will inevitably reduce the set of providers which a given fabless manufacturer can utilize, but that wasn't what you claimed as far as I can discern.

     

    Our most important point of disagreement isn't really that though.  It's that you seem to insist that it makes perfect sense for Broadcom to do nothing about assisting the non-stop manufacture of BCM2835 devices despite knowing since March the overall levels of interest, despite having an inside route into per-partner demand information through RPF, despite knowing that every chip manufactured in the current months will be sold because solid order queues exist for them, and despite being able to discuss the Foundation's 2013 plans with Eben Upton owing to RPF's intimate interdependency with Broadcom to ensure that there are no surprises ahead.

     

    Instead of noting these special circumstances which create an effectively risk-free environment for BCM2835 manufacture for a certain number of months which Eben can undoubtedly quantify, you insist on treating the SoC orders as some anonymous corporate purchase request over which Broadcom has no knowledge nor control and which therefore results in an unacceptable manufacturing risk.  This just isn't so.  Pi is special.  Pi is as close to being a Broadcom product without officially being one as it gets.  The Pi alpha boards even had Broadcom's mark etched on them.  It's not some anonymous 3rd party that wants these Broadcom SoCs.  It's a family member, pretty much, and you can be confident that communications between the two parties are very close and very good.  Hindsight was not required by Broadcom, they have something far better, a direct channel to the right people and to the information they need to manufacture appropriate volumes safely.

     

    Now because you haven't done so, I'll hypothesize one theoretical risk that might exist, hypothetically.  It might be considered possible that RS would reject any faster supply of SoCs if they were produced and offered to them by Broadcom outside of contract, willing to let their customers wither of old age in the wait queue as long as they don't have to invest more than some predefined $X in Pi manufacture per quarter.  Yes it's theoretically possible, and maybe you were implying that this would constitute a real risk for Broadcom, but is it likely?  (Your allusions to risk did not make the sources of risk clear at all.)

     

    Well I really doubt that even the strongest detractor of RS would claim that there is any significant likelihood of that occurring.  I don't have any particular knowledge of RS, but even if they have some weaknesses, they are nevertheless one of those companies with a long pedigree that gets lumped into "Best of British", and the likelihood of them turning down SoCs to vanquish their backorder queue is remote, in my view, and AFAIK nobody has suggested that that is a real danger.  So from where does the risk and uncertainty that you've implied actually come?  It's really just FUD.  There can be no uncertainty nor doubt about any BCM2835 device manufactured not ending up on Pi boards and getting sold when this is done in concert with RPF as coordinator, and fearmongering about it is not helpful.

    Almost everything in Ms Divonas post isn't right. I can't be bothered to quote all of it because its late, but most of her statements would need the use of a crystal ball to make a decision. And I've never got those dingers to work properly.

     

    Face it Morgana, you are wrong here. I know you are finding that difficult to accept, but you have two people who have worked in the industry telling you stuff, and yet you still don't beleive them. Why are you so confident you are right, and the experts are wrong, in the face of so much contrary evidence? You are working from heresay and speculation, and have people giving you facts, and yet, still you thing you are right. That's mucho dingo dudette.

     

    Actually, one point is worth adding - that of excessive capacity in the third party fabs industry. There is a lot of capacity for sure, but not SPARE capacity. If there was spare capacity, there wouldn't  be a long lead time - you could just get in there and use it now. So you can make a hell of a lot of chips, if you book ahead. Which means the alledged shortage now is due to an order not being big enough 3-4 months ago. Since fabless companies in this area are not in the game of making stuff in advance and storing it just in case, the ordering decision back them was underestimated. Which is understandable - who would have expected the demand to still be so high a year after launch. That's pretty unusual.

    Billy:  Look up "argument from authority" and "logical fallacy".

     

    Then come back to us with solid reasoning instead of your repeated "It's like this because I'm experienced and I say so."  It's not convincing in an engineering forum.  If you're truly experienced then it should be easy for you to provide a reasoned argument rather than your standard line.

     

    mynameisJim and I have exchanged reasoned arguments without name-calling nor arguing from authority.  We may not agree but it's a logical exchange of views.  Try it, it will stand you in good stead.

     

    Your last paragraph might even have qualified as logical if you hadn't incorporated another logical fallacy, a simple straw man.  "fabless companies in this area are not in the game of making stuff in advance and storing it just in case" is the straw man because it's not "just in case", it's to fulfil the solid and well-known back-orders for Pi held by the manufacturing partners.  I stated that plainly in the preceding post to which you were replying, so you're countering a premise that was never made.

    Arguing bitterly over conjecture and idle speculation is surely a sign of a species with too much time on it's hands...

     

    From a manufacturing point of view I have to concur that it makes little sense for a manufacturer (especially one with no actual manufacturing capability) to push an obsolete, low profit item to the head of a carefully planned queue. I would imagine that the main value of the 2835 / Pi thing to Broadcom is in terms of public relations, so possibly a beancounter in a Cambridge office knocked out a cost / benefit analysis a long time ago, while other grey suits got on the trumpet to their pet fabrication subcontractors - only to be given the option of being bent over a barrel. One has to look after one's important customers (and shareholders) first, so unless one can conjure manufacturing capability out of thin air and defy the laws of physics to shrink lead times, somebody is going to have to wait (especially if they didn't order enough in the first place). In fairness, it would have taken a crystal ball rather than a spreadsheet to predict the level of sustained demand that the Pi has seen.

    Pretty shonky attitude there, Morgan.

     

    Nothing I've said is wrong, or a straw man argument. And I reckon my experience actually working in this sector and actually knowing what I am talking about  trumps your inconsistent arguments. Don;t give me nonsense about reasoned argument  - you dont need to argue when presented with actual facts. You lost, admit it, or are you incacable of accepting you could be wrong about something. That's not reasoned argument, that being bloody minded.

     

    For example, my statement "fabless companies in this area are not in the game of making stuff in advance and storing it just in case" is completely true and contains no straw shaped man. You in an earlier post stated Broadcom should make a load of chips up front without receiving  orders. I told you this is not the way they work. They make according to the backorders they are told about i.e by the people who actually know the numbers ie RS and Farnell.  They don;t make stuff that hasnt been ordered. They might make stuff up front if they are told by the manufacturer they expect to sell a particular number, but that owuld need to be a multi million chip order, not the small change orders fom the Raspberry Pi foundation. Some chip companies do make to fill warehouses, not companies like Broadcom, that's not their business. I dunno specifics, as I don;t work for any of them, but the only way Broadcom could know the actual order numbers required in the backlog is if RS or Farnell told them, and they way they do that is by ORDERING THEM. So they order enough for the backlog, plus the extra they expect to sell between receipt and the next order time. My guess is the RS completely failed to anticipate the demand would still be high and failed to order enough. Broadcom has exactly the same number of working crystal balls as anyone else, so without numbers from orders, they ain;'t gonna guess how many to make.

     

    Jesus, its the middle of the night and I'm still arguing. People who cannot accept they have lost an argument do my blood pressure no good at all. Dunno why I bother. Must be the beers!

    Every single post of yours is full of personal comments like that.  Try sticking to the subject and not attacking people but dealing exclusively with what the people say.  Don't refer to me, refer to what I am saying.  This will only cramp your style if you don't have a solid line of reasoning in the first place and therefore rely on abuse and ad hominem.  But if you do actually have something logical and reasoned to say then it will not cramp your posts at all.  Try it.

    I gave the precise details of your straw man argument, and it's not a matter of dispute because it was in your own words in black and white.  If you try to knock down an argument by adding a premise of your own that was not given and knocking down this new premise then that is the exact definition of a straw man argument.  It isn't a logical counter to what was said, but only a logical counter to the premise which you invented.  Don't do it.

    I've gone over this before, but to help you along, I'll repeat what I already said.  The "just in case" was not what I suggested.  I very clearly suggested that they could work with Eben Upton and everyone else concerned to ensure that there was no risk by virtue of fabricating only enough parts to cover existing solid order backlogs.

     

    If you put "just in case" in your counter then you are countering with a straw man argument.  It does not matter that the statement you are making is true when expressed without reference to a previous argument (in that case you would just be making a hypothesis yourself and debunking it).  When used in a counter to someone else's argument then it becomes a straw man because it does not deal with that person's argument but only with the premise you introduced yourself, and yet attributes the "success" in debunking it to the failure of the other person's argument when it is only a failure of your invented argument.  It exactly matches the fallacy type.  Don't do it.

    I agree with that, but once the game has started, we are where we are and it has to run its course.

     

    When Eben was designing the Pi, issues of whether Broadcom would be interested in longevity of the BCM2835 should have been discussed.  Perhaps a chip in which they have more interest would have been a better choice.

     

    It's a bit late to talk about that now though.  We are where we are, and Broadcom is lumbered with continued fabrication of an old SoC.  If they're unhappy about that then the best thing they could do is to get these blasted preorders out of the way by accellerating BCM2835 manufacture and at the same time work in concert with Eben to design the next version of Pi around a more modern SoC.

    First off I agree with Mogaine, there is no need for name calling.  Secondly, "argument from authority" (from wikipedia)

     

    The strength of the [argument from authority] depends upon two factors:

    1. The authority is a legitimate expert on the subject.
    2. There exists consensus among legitimate experts in the subject matter under discussion.

     

    The two factors — legitimate expertise and expert consensus — can be incorporated to the structure of the statistical syllogism, in which case, the argument from authority can be structured thus: [2]

    X holds that A is true.
    X is a legitimate expert on the subject matter.
    The consensus of subject-matter experts agrees with X.
    Therefore, there exists a presumption that A is true.

     

    Fallacious appeal to authority

    Fallacious arguments from authority often are the result of failing to meet at least one of the required two conditions (legitimate expertise and expert consensus) structurally required in the forms of a statistical syllogism.http://en.wikipedia.org/wiki/Argument_from_authority#cite_note-salmon-1

     

    (end of Wikipedia quote)

     

    Now there is a consensus on this matter between two legit experts on the subject matter (plus Garry and Jonathan but they have not stated their experience in the matter so I didn't count them), and persons X are holding that A are true, therefore the breakdown must resolve around the belief that X is a legitimate expert on the matter which I freely admit that I cannot prove my expertise in the matter (or anyone else for that matter) any more than you can prove you are a mid-aged black haired woman named Morgaine.

     

    The fallacy around appeals to authority revolves not around multiple experts being wrong (though it can happen, it becomes increasingly unlikely) nor around "I can ignore anything said by someone claiming to be an expert because their expertise doesn't count", but around giving added weight to experts on things they shouldn't be given extra authority on (such as giving extra weight to an airlines pilot claim of seeing a UFO because they're trained observers of the sky.

     

    Now I admit, I'm not much of a philosopher and if you want to take this argument into the realm of philosophy of possibilities rather than realities of engineering (like arguing that a resistor won't behave in manner X despite never having done anything with resistors and stating all my years of working with resistors is wrong because it goes against how you think the ideal world scenario of resistors should operate) then I'm going to loose, hands down.  But it seems to me that the basis for your argument has some fallacies of its own.  "Association resulting in causation", "Ad ignorantiam", (side note a straw man argument is attacking a side issue to hide the fact that you're wrong about the main issue), and while I don't know the proper term for it, an unsound premise (namely, B-com wants to keep the BCM2835 in constant production despite the fact that all the sales for the raspberry pi don't amount to 1/1000th of their quarterly earnings)

     

    The Association resulting in causation is Eben working for B-com will result in B-com producing more units (which is a double fallacy because it also implies that Eben can somehow know how much demand is upcoming for the pi, when it's been stated from Liz that they have to wait to hear from the distributors just to find out how many have been sold a month ago.)

     

    The Ad ignorantiam is the repeated phrase "it's all speculation" with the rest of the post going on to say therefore I'm right. (This is also a double fallacy because it attempts to equate your speculation about how our fields of expertise work with our knowledge of how our fields work and nullify both as meaningless, indeed it actually tries to trump expertise with strong opinion).

     

    I'll throw in one last one and that's the fallacy fallacy (you might want to google it).  Where you say the "just in case" is a straw man (which doesn't really fit the mold of attacking a weak position to hide the fact you can't attack the main one)

     

    Finally, and I don't know the name for this one either, but there is a fallacy where you try to claim that an engineering forum doesn't care about experience.  That's all an engineering forum cares about.  If I have problems with a circuit I don't want some wet behind the ears kid with a head full of text book answers from circuits 101 trying to tell me how the part of the circuit I've tested could never operate because of thing "x". I want someone with lots of real world experience to say "oh yeah, I've been here"

     

    *whew* that post took forever, I'm really no good at this philosophy crap!  lol.  I don't know what else to tell you Morgaine (This might be ad hominem), but if you want to dig your heels in and shout that your opinions trump my experience.  I don't think there's anything I can do about that.  I've worked with enough children to know that's a battle lost when you first step foot on the battlefield!  I just wish you'd stop pushing these opinions of your as such strong facts, not only for the sake of people who are equally unaware and believe you, but also for your own sake and image with people who do know better. 

     

    With that I've said all I can say about the matter and I promise you can have the last word and prove how you're right about all this and I won't say anything back image
