  4. It's not price - it's about not wanting a Ferrari on Why the Tablet Market is Really the iPad Market · · Score: 1

    As a person who has rolled our 200 tables in their company, saying it is just about price is misleading. Yes, price is a factor. But it's also about being about being able to choose the price you want to pay.

    There is no doubt in my mind that if you want a device with iPad's specs, the iPad is the best value for money. I don't know how they have done it, but in a complete turnaround Apple has become the lowest cost manufacturer. Hell, if I try to buy a laptop with the same specs as a MacBook Pro retina from Dell, it literally costs more than twice as much where I live. Unbelievable, given Apple's past reputation for being a premium manufacturer.

    The problem is we don't need a tablet with the iPad's specs. We just need a reliable 10" tablet with WiFi. An Android 10" tablet may not be the same value for money as an iPad for what you get, but it is cheaper, substantially cheaper. Pair it with a Android phone and it really becomes lopsided. An iPhone - $700. An Android phone, IP67 rated, $200. And then we can write apps that run on both the phone and the tablet. You can't get a IP67 rated iPhone, let alone one for $200. That brings the price of the total system with the features we want to around 1/3 of Apple can provide.

    That IP67 phone sums it up really. It's about choice, the Android ecosystem gives you huge range of choices whereas Apple doesn't. Apple will most likely continue to dominate market where the choose to play. But that is the upper end, and the upper end is always the smallest end. Numerically Android will come to dominate in tablets over time, just as they have in smart phones.

    then iterated hashes would get less secure the more iterations you use.

    Maybe they are. The enhanced security comes from it taking longer compute. Chaining may actually increase the chances of a collision, but at least chaining the same hash doesn't combine the weaknesses of two hashs.

    IMHO, no, it isn't better. I am using the current stable version 3.4.3, and this is the worst version so far. It hangs while fetching email multiple times a day and connecting to GMail's IMAPS service is flaky. The UI has bugs - like displaying the source of an email using black text on a black background.

    Worse, they have made some design decisions that scare me. They have moved from mbox format to maildir. That it itself is on the balance a good thing although it massively slows down full text searches. But they use one maildir for the entire local store (ie, all folders such as the Inbox, Sent, ... are in the one maildir). At the same time they have removed metadata information that used to be stored in X-Evolution headers in the email out to a sqlite database.

    The reason this scares me is old design had one wonderful feature - when it's metadata got corrupted, it simply rebuilt it from the mbox. Yes, waiting rebuilding this metadata could take a looong time and was a frequent source of complaints. But in exchange in 10 years Evolution hasn't lost a single byte of data. In this new design when the sqlite database gets corrupted (which it will) all the information that is stored only in it will be lost. Yuk, yuk yuk.

    The final thing that irks me about Evolution is to this day it provides no way of purging individual messages. I delete messages as I deal with them. Later I archive the deleted ones in the Trash folder. Numerically most of my email is fluff - nagios messages, logs from computers, and the like. The easy way to archive is to purge all of the fluff, then copy what is left in Trash to the archive. Or it was. Since Evolution can't purge I wrote a program that did it for the mbox format. But of course that no longer works, and in the mean time Evolution hasn't provided a solution.

  14. Re:Could make sense on Australia's Telstra Requires Fibre Customers To Use Copper Telephone · · Score: 1

    The telco (unless it is third world) will have massive diesel generators

    As an Australian resident I can assure you they do. We saw them in operation during cyclone Yasi last year. Those diesel generators kept chugging along right up until the exchange was flooded or they ran out of fuel. At that point the entire exchange area dropped out.

    Cyclone Yasi showed us in Australia this "land line is the most reliable during an emergency" thing is just a myth. After the cyclone was over, the service techs come online again and told us what was the most reliable. The order is:

    1. Mobile phones. Yes the local tower was often taken out, but the user could just find another one by standing on a hill. The mobile phone has a battery, which meant a candy bar phone lasted for days. The most reliable thing was a mobile phone + car + car charger + fuel for car. Nothing else came close. And surprise, surprise, most people has this, and thus remained connected during the entire cyclone. They even had an internet connection!
    2. Land line with a POTS telephone. These lasted until something got flooded - be it the exchange or a pit in the street. That averaged a day or so. The flooding isolated many areas for a week or more. Huge amounts of the power grid were taken out including transmission lines, so in some cases it took weeks to restore it. Sparodic mobile coverage was kept up by flying in fuel for generators. Land line coverage - well much of it just had to wait.
    3. Land line with some fancy device attached that required mains power. These died as the cyclone took out the power grid, which was in the first few minutes.

    The bottom line is mobile coverage failed gracefully, meaning it never died completely. Bits of it died, capacity was reduced, but communications for important stuff like emergency SMS's was always available. Much of the land line coverage on the other hand failed catastrophically, meaning that for a short while it did better than mobile and then it died completely and utterly, for weeks.

  15. Re:Typical on Australia's Telstra Requires Fibre Customers To Use Copper Telephone · · Score: 1

    Quality will be about the same unless wideband VoIP is deployed (almost no one has done that)

    With the NBN Australia is replacing POTS with wideband VOIP, which is rather pertinant considering Australia is the country we are talking about here.

    And VOIP doesn't have to be wideband. The price should plumet. Narrowband VOIP is just a 64Kb/s stream with QoS. A 1 minute voice call chews up $0.0001 of data, even at Australia's inflated prices for data. Currently the telco's here charge far more than 10,000 times that. The justification is I think they have to pay for all the switching gear in the exchanges, and the data has to flow through their equipment. Under the NBN all that changes. The currently analogue switching gear will become land fill - replaced by internet routers. SIP does not require the data to be pushed through the telco - the telco's role is to set up a RTP steam that goes directly between the end points. The voice provider get reduced to being a lookup service so one party can discover the IP address for a phone number.

    Then there are the other features provided by SIP - like transferring calls, conference calls, video, and the ability to use your mobile phone as a handset while in the house. Copper provides none of this.

    In other words contrary to what you say VOIP does indeed provide lots of advantages over analogue. It is orders of magnitude cheaper, while providing many more features.

    Yes, there were a lot of "rogue" DHCP servers at LCA, although a better term might be miss-configured because I am almost certain it wasn't deliberate. But the story neglects to mention the reason. Attendees were invited to set up wireless access points because the accommodation didn't provide wireless. There were I guess 20 or 30 units, and I be surprised if every one of those units didn't have at least 1 AP set up by a community minded resident. It is inevitable that some of those will have forgotten to turn DHCP off, or perhaps plugged the internet connection into the switch rather than the upstream port on the router.

    This is avoidable. LCA owns some 50 or so access points, which have been deployed in the past to supply wireless to the accommodation. Doing so means the attendees don't bother unpacking their access points, and the rogue DHCP problem goes away. However, deploying those access points takes a substantial amount of time and organisation. LCA is run by volunteers. So they have a tradeoff - they can put in a substantial amount of work and the problem largely goes away, or deal with the problem during the conference as it arises. As LCA attendees are a pretty sophisticated bunch networking wise, either way works well enough.

    The one thing that doesn't make any sense is blaming the attendees, which is the way this story tries to slant it. That is like leaving the nappy off the baby and then blaming it for the piss on the carpet. The consequences of not supplying wireless are entirely predictable. Reasonable adults either supply wireless, or accept the consequences and don't whinge about it.

    A more interesting topic of discussion is the collapse of the network in the accommodation on Friday night. In hindsight the cause is obvious. For the second LCA in a row they got all most of the conference video's up before the conference closed. Come Friday night many attendees decided to download huge quantities of them, the usual reason given being "so I have something to watch on the way home". It was a really good idea actually - LCA this year had 4 streams, and inevitably people ended up missing what in hindsight were "must see" talks. The problem was the link between the residences and LCA simply could not cope with the traffic.

    Again, that could have been solved. Indeed it was solved at LCA 2011 using DNS tricks. In that year a copy of the videos was put on a server in the residences, and FQDN for the video server resolved to that server for the residences only. Or perhaps enabling torrents for the videos would have worked well enough. As it was, internet connectivity was almost non-existent Friday night, and that caused howls of anguish - far more anguish than the rogue DHCP servers.
