• Problem getting GOBI 2000 HS to work

  - by Zypher

  I've been trying to get my integrated GOBI WWAN card to work under 10.10 for a while now. I was able to get the network manager to see the card after installing the gobi-loader package. I was able to setup the connection, but i cannot establish a connection to Verizon. Below is the output from /var/log/daemon.log as i try to connect.

It wraps up with an in-depth look at layout components, and a second helping of additional region considerations if you just can’t get enough.

• Read-only view of a Java list with more general type parameter

  - by Michael Rusch

  Suppose I have class Foo extends Superclass. I understand why I can't do this: List<Foo> fooList = getFooList(); List<Superclass> supList = fooList; But, it would seem reasonable for me to do that if supList were somehow "read-only". Then, everything would be consistent as everything that would come out of an objList would be a Foo, which is a Superclass. I could probably write a List implementation that would take an underlying list and a more general type parameter, and would then return everything as the more general type instead of the specific type. It would work like the return of Collections.unmodifiableList() except that the type would be made more general. Is there an easier way? The reason I'm considering doing this is that I am implementing an interface that requires that I return an (unmodifiable) List<Superclass>, but internally I need to use Foos, so I have a List<Foo>. I can't just cast.

• most reliable linux terminal app / general procedures for process stability

  - by intuited

  I've been using konsole (KDE 4.2) for a while now but it crashed recently. Konsole is efficiently designed to use one instance for all of the windows for your entire X session. Extra-unfortunately, because of this ingenuity the crash brought down all the humpty-dumptys and their bashes and their bashes' applications and all the begattens' begattens all the way down to Jebodiah Springfield into one big flat nonexistent omelette. The fact that this app is capable of crashing under any circumstances is pretty disappointing. Although KDE 4.2 is not expected to be entirely stable -- and yes, I know, I should update my distro -- it's still a no-sell for me, since if at all possible, this sort of thing Shouldn't Happen to something that's likely to be a foundation for an entire working environment. Maybe this is arrogant and unrealistic, but if it's possible to have something more stable, I want it. So other than running under screen -- which is fun, nifty, and thus far flawless in its reliability, but which has some issues with not understanding certain keycodes -- I'm looking for ways to improve my environment's reliability. The most obvious strategy is to cast about for a more reliable console app. A standard featureset -- which to me includes tabbed windows, Unicode support, and a decent level of keyboard shortcut configuration -- is pretty much essential. I'm currently running gnome-terminal and roxterm, both of which have acceptable featuresets (pretty much identical, actually; I think rox is actually the superset), and neither of which have provided me with extensive, objective reliability data. Not that they were expected to. Other strategies are also welcome. Were I responding to this question I would perhaps suggest backgrounding critical tasks with & and/or disowning them so they don't come down with the global pandemic. And stuff like that.

• General Website Security

  - by Tom

  I pay monthly for a website hosting service that provides me with PHP and FTP support. I can upload my files and create directories and such. Now, I am wondering... If I upload a folder full of images.. or music.. basically personal stuff to my website and name it 'junk1234' can other people find it? Or even search engines? If so, How would I restrict any but those who know the folder name from seeing files in it? Possibly httaccess files? I also have cpanel installed.

• What is the general process of web hosting?

  - by ggfan

  I want to upload my site public so people can use it. I am currently using a free PHP webhosting company that supports up to a certian amount. When sites that say they offer unlimited upload, data, etc for like $10/month, is that all you need to run a big site? Or how do I host a big site, if it gets popular?

• General-purpose unix-based network authentication tool?

  - by Patrick Collison

  I want something that'll integrate auth across SSH, web (ideally including SSL, with the option of authenticating with either client-side cert or password, like they do at MIT), and whatever applications want to use it. Kerberos seems to best fit what I want, but tool support seems surprisingly poor. What do people use these days?

• General video performance affected on Mac OSX 10.5 (PowerBook G4)

  - by r0ca

  Hi all, I'm quite new to Mac and I just got a PowerBook G4 for free. I installed OSX 10.5 on it and for the first two weeks, everything was going kinda smooth even if this is similar to a P3. I'm not expecting awsome video performance but at least be able to watch some videos from Youtube. Yesterday night, I installed Office 2008 for mac and this morning, even after a reboot, my computer is way much slower that I used to know. I watched a youtube video and the framerate was 1:1. I also noticed it on flash adds, it's way slower! Is there anything that I can do to increase video performance, see what's the process list running and taking more GPU or CPU, what's taking more ram and stuff like that?! What do you guys, Mac pros, would do on an old laptop with OSX 10.5 Thanks!

• Some general questions about Adobe fonts.

  - by aviraldg

  Questions: The Adobe fonts look distinctly clearer and much better than Arial. Any particular reason? Why does Adobe Caslon Pro show up among "C"s? (I know, Caslon starts with "C", but the font's name starts with "A", right?) Are more fonts like these available somewhere? (By "these", I mean non decorative, regular, and smooth) Why are there two versions of certain fonts like Adobe Heiti, which has: @Adobe Heiti and Adobe Heiti (which are not exactly the same, btw.) Thanks.

• Cannot create Hyper-V Virtual Machine - General Access Denied 0x80070005

  I have the standalone Hyper-V Server 2012 running and I'm trying to create the first VM on it but I'm getting the following error: From my research, this error comes up with something related to the Intel IPMI driver but I have an Asus motherboard so I didn't think it was the problem. However, I ran the ResetAccess.exe fix anyways and to no surprise it said something like "This version of Windows does not require this fix". Thank you

• General name for Macs' operating system

  - by andy124

  First of all, I hope that my question is fairly suitable for this site. I have a website where I would like to write articles about some operating systems. Therefore, I have created a main category called "Operating systems". Within a subcategory, I would like to write articles about Apple's operating system that is running on Macs. However, I do not know what to name this category. I have always thought the name was just OS X, but come to think about it, the "X" is actually part of the version (10). Therefore I cannot exactly call my category OS X, because what about when OS 11 is released in a few years? And since Apple has gone from Mac OS X to just OS X, then I cannot use "Mac OS". And, if I remove the X from OS X, then I only have "OS" left, which does not seem so proper. I am really looking for a meaningful all-round name for the Macs' operating system that does not involve the versioning. I was thinking about just calling the category "Mac", but that is not precise either - but perhaps the closest I can get?

• General High-Level Assessment

  - by tcarper

  Guys and Gals, I've been tasked with a doozy of an assignment. The objective is something akin to "laying of hands" on several database servers which work in concert to provide data to various Web, Client-Server and Tablet-Sync'd distributed Client-Server programs. More specifically, I've been asked to come up with a "Maintenance Plan" which includes recommendations for future work to improve these machines' performance/reliability/security/etc. Might there be some good articles on teh interwebs ya'll could point me towards which would give me some good basis to start?

• Proxy - Some general questions

  - by user68802

  Is it possible to accomplish the following scenario with a proxy server? We are having one internet facing server that we want to put behind a proxy for some reasons. We want everything to work as before. When they do a request all connections will be forward to the internal server which will send back the information through the proxy. We want to be able to change to proxy to show an maintenance page whenever we are doing maintenance and change it back to forwarding traffic when we are done. We do also want to be able to keep forwarding all users that are using the sites but show an maintenance page for all new users for a time before showing the maintenance page for everyone in order to give the users some time to finish their work before kicking them out.

• Google Maps: remember id of marker with open info window

  - by AP257

  I have a Google map that is showing a number of markers. When the user moves the map, the markers are redrawn for the new boundaries, using the code below: GEvent.addListener(map, "moveend", function() { var newBounds = map.getBounds(); for(var i = 0; i < places_json.places.length ; i++) { // if marker is within the new bounds then do... var latlng = new GLatLng(places_json.places[i].lat, places_json.places[i].lon); var html = "blah"; var marker = createMarker(latlng, html); map.addOverlay(marker); } }); My question is simple. If the user has clicked on a marker so that it is showing an open info window, currently when the boundaries are redrawn the info window is closed, because the marker is added again from scratch. How can I prevent this? It is not ideal, because often the boundaries are redrawn when the user clicks on a marker and the map moves to display the info window - so the info window appears and then disappears again :) I guess there are a couple of possible ways: remember which marker has an open info window, and open it again when the markers are redrawn don't actually re-add the marker with an open info window, just leave it there However, both require the marker with an open window to have some kind of ID number, and I don't know that this is actually the case in the Google Maps API. Anyone? ----------UPDATE------------------ I've tried doing it by loading the markers into an initial array, as suggested. This loads OK, but the page crashes after the map is dragged. <script type="text/javascript" src="{{ MEDIA_URL }}js/markerclusterer.js"></script> <script type='text/javascript'> function createMarker(point,html, hideMarker) { //alert('createMarker'); var icon = new GIcon(G_DEFAULT_ICON); icon.image = "http://chart.apis.google.com/chart?cht=mm&chs=24x32&chco=FFFFFF,008CFF,000000&ext=.png"; var tmpMarker = new GMarker(point, {icon: icon, hide: hideMarker}); GEvent.addListener(tmpMarker, "click", function() { tmpMarker.openInfoWindowHtml(html); }); return tmpMarker; } var map = new GMap2(document.getElementById("map_canvas")); map.addControl(new GSmallMapControl()); var mapLatLng = new GLatLng({{ place.lat }}, {{ place.lon }}); map.setCenter(mapLatLng, 12); map.addOverlay(new GMarker(mapLatLng)); // load initial markers from json array var markers = []; var initialBounds = map.getBounds(); for(var i = 0; i < places_json.places.length ; i++) { var latlng = new GLatLng(places_json.places[i].lat, places_json.places[i].lon); var html = "<strong><a href='/place/" + places_json.places[i].placesidx + "/" + places_json.places[i].area + "'>" + places_json.places[i].area + "</a></strong><br/>" + places_json.places[i].county; var hideMarker = true; if((initialBounds.getSouthWest().lat() < places_json.places[i].lat) && (places_json.places[i].lat < initialBounds.getNorthEast().lat()) && (initialBounds.getSouthWest().lng() < places_json.places[i].lon) && (places_json.places[i].lon < initialBounds.getNorthEast().lng()) && (places_json.places[i].placesidx != {{ place.placesidx }})) { hideMarker = false; } var marker = createMarker(latlng, html, hideMarker); markers.push(marker); } var markerCluster = new MarkerClusterer(map, markers, {maxZoom: 11}); </script>

• Are there some general Network programming best practices?

  - by uriDium

  I am implementing some networking stuff in our project. It has been decided that the communication is very important and we want to do it synchronously. So the client sends something the server acknowledges. Are there some general best practices for the interaction between the client and the server. For instance if there isn't an answer from the server should the client automatically retry? Should there be a timeout period before it retries? What happens if the acknowledgement fails? At what point do we break the connection and reconnect? Is there some material? I have done searches but nothing is really coming up. I am looking for best practices in general. I am implementing this in c# (probably with sockets) so if there is anything .Net specific then please let me know too.

• Glassfish V3 won't start

  - by Zakaria

  Hi everybody, I installed NetBeans 6.8 and tried to run the GlasshFish V3 server. I'm working under Windows Vista 32 Bits. First, it won't run. Then I modified the c:\Windows\System32\drivers\etc\hosts file and put the following line into it: 127.0.0.1 localhost And when I run the GlasshFish V3 Server, no error is showing but only "INFOs" are displayed: 3 avr. 2010 19:23:19 com.sun.enterprise.glassfish.bootstrap.ASMain main INFO: Launching GlassFish on Felix platform Welcome to Felix ================ INFO: Perform lazy SSL initialization for the listener 'http-listener-2' INFO: Starting Grizzly Framework 1.9.18-k - Sat Apr 03 19:23:24 CEST 2010 INFO: Starting Grizzly Framework 1.9.18-k - Sat Apr 03 19:23:25 CEST 2010 INFO: Grizzly Framework 1.9.18-k started in: 423ms listening on port 35127 INFO: GlassFish v3 (74.2) startup time : Felix(4456ms) startup services(1709ms) total(6165ms) INFO: Grizzly Framework 1.9.18-k started in: 459ms listening on port 35116 INFO: Grizzly Framework 1.9.18-k started in: 428ms listening on port 35155 INFO: Grizzly Framework 1.9.18-k started in: 470ms listening on port 35160 INFO: Grizzly Framework 1.9.18-k started in: 513ms listening on port 35159 INFO: javassist.util.proxy.ProxyFactory.classLoaderProvider = org.glassfish.weld.WeldActivator$GlassFishClassLoaderProvider@5be8f4 INFO: Hibernate Validator bean-validator-3.0-JBoss-4.0.2 INFO: Binding RMI port to *:35165 INFO: Instantiated an instance of org.hibernate.validator.engine.resolver.JPATraversableResolver.

• Story of success: MySQL Enterprise Backup (MEB) was successfully integrated with IBM Tivoli Storage Manager (TSM) via System Backup to Tape (SBT) interface.

  - by user13334359

  Since version 3.6 MEB supports backups to tape through the SBT interface.The officially supported tool for such backups to tape is Oracle Secure Backup (OSB).But there are a lot of other Storage Managers. MEB allows to use them through the SBT interface. Since version 3.7 it also has option --sbt-environment which allows to pass environment variables, not needed by OSB, to third-party managers. At the same time MEB can not guarantee it would work with all of them.This month we were contacted by a customer who wanted to use IBM Tivoli Storage Manager (TSM) with MEB. We could only say them same thing I wrote in previous paragraph: this solution is supposed to work, but you have to be pioneers of this technology. And they agreed. They agreed to be the pioneers and so the story begins.MEB requires following options to be specified by those who want to connect it to SBT interface:--sbt-database-name: a name which should be handed over to SBT interface. This can be any name. Default, MySQL, works for most cases, so user is not required to specify this option.--sbt-lib-path: path to SBT library. For TSM this library comes with "Data Protection for Oracle", which, in its turn, interfaces with Oracle Recovery Manager (RMAN), which uses SBT interface. So you need to install it even if you don't use Oracle.--sbt-environment: environment for third-party manager. This option is not needed when you use OSB, but almost always necessary for third-party SBT managers. TSM requires variable TDPO_OPTFILE to be set and point to the TSM configuration file.--backup-image=sbt:: path to the image. Prefix "sbt:" indicates that image should be sent through SBT interfaceSo full command in our case would look like: ./mysqlbackup --port=3307 --protocol=tcp --user=backup_user --password=foobar \ --backup-image=sbt:my-first-backup --sbt-lib-path=/usr/lib/libobk.so \ --sbt-environment="TDPO_OPTFILE=/path/to/my/tdpo.opt" --backup-dir=/path/to/my/dir backup-to-imageAnd this command results in the following output log: MySQL Enterprise Backup version 3.7.1 [2012/02/16] Copyright (c) 2003, 2012, Oracle and/or its affiliates.

This is only story of one success which can be useful for someone else. MEB is not regularly tested and not guaranteed to work with IBM TSM or any other third-party storage manager.
