I'm not complaining about the home button moving on my own behalf. (Personally I just use the bookmarks toolbar, or bookmark keywords.) As a network administrator I deploy Firefox on all the computers in my workplace, and the list of things I have to do on _each_ of those computers to get new versions into a state where users don't freak out and panic and demand the old version back has tripled in length over the last year or so. Putting the buttons back in their traditional arrangement is one of those things. For some reason, users don't complain much about the back and forward button being connected to each other. Go figure. But they do complain, bitterly, when UI elements move to different places.

    > And when will Mozilla stop screwing around with the UI?

    When pigs fly, I think. As near as I can tell, user expectations got changed over from something that Firefox wanted to meet to something that Firefox specifically wants to break, sometime around version 1.5. The gratuitous UI changes were minor at first (little things like the first round of changes to how bookmarks work), but the growth rate of their significance appears to be geometric: if rearranging the order of the standard buttons (back, forward, reload, stop -- not that the stop button in Firefox has EVER worked correctly) wasn't new and interesting enough for you, hold on to your seat, because in version three we're completely altering how the location bar works, and then version four changes the whole top of the browser window around so much you won't even recognize it.

    Soon we'll be doing away with the tired old "back button" concept, ranking the pages in your history by their *popularity* (as determined by other users), and presenting them visually as part of Panorama. Also, "scrolling down" will be replaced with "zooming in", which you can do with multi-touch trackpad gestures, and manually-created bookmarks will be phased out in favor of assigning ratings (one, two, three, four, or five stars) to the items in your history, which informs your search results when you use the Awesomeness Bar. The bookmarks toolbar will obviously be going away, and also bookmark keywords, and the tab bar will be merged into the Awesomeness bar as well, so instead of having a bar of tabs that you can switch to, you can just use the Awesomeness Bar to search through your open tabs just like you would search through your history.

  10. The most important step... on Ask Slashdot: Does SSL Validation Matter? · · Score: 1

    The most important thing that needs to be done is to fix things so that the client can know if the cert has unexpectedly changed.

    In its current state, https seems to be mostly concerned with fighting cheap MITM attacks against sites that the user has never visited before. This is stupid. It's FAR more important to prevent moderately-difficult MITM attacks against sites that the user visits on a regular basis. SSH handles this well, but it only works as well as it does because the user can be expected to know when the server's cert is legitimately expected to change -- a practical impossibility with HTTPS. HTTPS doesn't even try: anyone on the (very long and rapidly growing) list of people who can sign certs (that the browser will recognize) can provide a valid new cert at any time, for any site, and the user will never even know that the site's cert has changed. This is very bad.

    The solution is for the site, whenever it is visited, to supply the user with information about when the cert is expected to change next, and for the browser to REMEMBER this (with the cert). If the cert changes unexpectedly, alarms go off.

    Currently, scary alarms go off mostly when the client computer's date is incorrect -- which happens frequently on older computers, because the coin cell on the motherboard dies. (Current browsers make no attempt whatsoever to verify that it really is 2185 or whatever before presenting the user with the big scary warning about the site's cert being invalid, and the warning doesn't say "either your computer's date, 25 January 2185, is WAY OFF and it's really only 2010 or so, OR ELSE the server's cert is expired.") Even if the date could be verified independently, the current approach assumes that a cert that WAS valid but has been allowed to expire is a great deal riskier than a cert that wasn't expected to change for another eight months and has suddenly been altered for no reason. This is wrong and backward. A cert that changes (more than a few days) before it was to expire is in principle WAY more likely to be nefarious than a cert that was allowed to expire before being replaced, especially if the new cert is signed by a different CA than the one that signed the previous cert.

    Close. From Google's perspective this is the easiest way (both technically and from a legal perspective) to be certain they are in compliance with the court's order. It's probably more than the court order strictly required, but doing a little more than the court actually requires is a completely acceptable way to make sure you've complied. Doing the bare minimum, in a situation like this, would actually be substantially more bother, requiring more time from both the lawyers (interpreting the exact extent of the court's requirements) and the engineers (implementing it). Google already has a delisting mechanism, so throwing the site in question completely into the bit bucket was very easy. The lawyers only need about four seconds to be pretty sure that it's enough to satisfy the court, and the engineers need even less time to implement it. Sorted. And it hurts Google not at all, because sites with this poor an understanding of the web aren't really worth listing anyway.

    Now, I suspect what the paper thought they *wanted* is more like exactly one single result, pointing to their main page, preferably at the top of the results. People who never bothered to read a basic introductory "What is the world wide web?" article back in 1994 (or are simply too mentally incompetent to understand the concept of hypertext) sometimes make the mistake of thinking this is what they want: only one result pointing to the main page, and no linking to or indexing of any other pages. Anyone who *knows* anything about the web can of course explain to you why this is in fact severely disadvantageous to the site, but that doesn't stop idiots from thinking it's what they want.

    *Most* of the people who make this mistake can be convinced to use robots.txt to achieve what they (mistakenly) think they want, and the world goes on. Their site languishes in obscurity because nobody can find anything except their main page (which typically doesn't have a lot of meaningful content), but when they go looking for their site in the search engines they type in the actual name of their organization, which brings it right up, so they're happy. Foolish, but happy.

    But every now and again a particularly thick-headed site comes along, run by people who keep extra lawyers on retainer in lieu of competent web developers, and they decide to take everyone to court instead of bothering to write a robots.txt file. One of these cases makes the news every few weeks, if you're paying attention.

    If the court has its brain turned on, they have a good laugh at the plaintiff's expense and life goes on. But going to court is always a bit of a gamble, because courts don't always have their brains turned on and cannot be relied upon to be entirely consistent in their rulings. So every few months a court somewhere in the world orders a search engine to stop listing or linking to various things on some site or another.

    That's because Windows does not provide a mechanism for applications to be automatically updated along with the operating system. (Except for Microsoft's *own* applications, of course, if you get Microsoft Update. That's, umm, special. But non-MS applications are not handled.)

    I can tell you what the API for this should look like. When an application is installed, it should supply the following information to the OS:

      2. URL for the feed of available non-security-critical bugfix updates.
      3. URL for the feed of available feature updates.

      5. Suggested frequency to check for security updates.

    If certain of the URLs don't apply, then they are not supplied. For example, if a commercial vendor does not issue free feature updates because you have to buy those, then the third URL would be blank. If a vendor does not supply separate bugfix updates because non-security bugs are just fixed in the next release, then the second URL would be blank.

    When the system administrator installs any application, the OS asks him which kinds of available updates to automatically download for this application going forward, whether to also automatically apply them, and how often to check (with the supplied suggestion being only the default; the sysadmin can easily pick a different value, or just check "when checking for OS updates" option).

    The update feeds would have to have a designated format, which would have to include provision for the signature mechanism, but that's the least part of the thing.

    If the OS had such an API, any application that implemented it could get automatically updated by the update mechanism built into the OS. It could happen in the background, automatically, even if the user isn't logged in. Then we wouldn't need eleventeen different applications and browser plugins and whatnot each running their own system-tray updater. jusched and Adobe updater and the OpenOffice updater and the Firefox updater and... they could all just go away, rendered unnecessary, and *one* process, built into the OS, could handle it all.

    (This design, BTW, would work for any OS, not just Windows. The major Linux distributions sort of don't need it as bad, because most of the installed applications are installed through the OS package management system anyway. Actually, for applications that are free-to-download, like Opera, apt basically does this already. If the vendor supports your distro, all the sysadmin has to do is add the proprietary repository to sources.list and voila, Robert becomes avuncular in your general direction.
