  • Survey says: Java technology rules

    - by hinkmond
    Eclipse came out with their Open Source Developer Report and Survey for 2012. In it, we see (in the words of the immortal Richard Dawson, RIP) "Surveys Says!": Java computer programming language is on top. See: Java is the top Here's a quote: The Eclipse community was invited to participate in the survey between April 23 and May 15 of this year. Skerrett says the Foundation promoted the survey primarily through social media (Facebook, Twitter) and online forums. Of the 840 people who responded, 732 completed the survey... So, now we know who's on top, we can keep this in mind the next time this question comes up on Family Feud. Hinkmond

  • Google a-t-il raté son entrée sur le marché des tablettes ? Android connaît une "croissance pénible" d'après DisplaySearch

    Google a-t-il raté son entrée sur le marché des tablettes ? Android connaît une "croissance pénible" d'après DisplaySearch Six mois après le lancement d'Android 3 (alias Honeycomb), force est de constater que les ventes des tablettes qui tournent dessus sont loin de défrayer les chroniques, elles ne semblent pas être en mesure en tout cas de freiner les ventes frénétiques de l'iPad d'Apple. Pour l'analyste Richard Shim de DisplaySearch, l'univers Android connaît une « croissance pénible » avec Honeycomb : « il est clair que les premières tablettes fondées sur Android ne s'écoulent pas aussi bien que ce que beaucoup attendaient, quelques marques avec lesquelles ...

  • SSL issue with emails

    - by JackWillDavis
    OK, so I have somebody hosting a site on my CentOS 5.8 Plesk 11 control panel. He has a EV SSL which is validating the site fine however he has failed the PCI check because it is saying his email servers (SMTP, IPAM, POP) have the wrong name on the servers. This is because his SSL certificate is not a wildcard certificate and the email servers are flagging the default Plesk SSL certificate. Is there a way to stop Plesk automatically connecting emails via the default SSL? I'm fairly new to things like this so I hope I've written everything I need, let me know if any more details are needed. Jack

  • Utilize two gateways on the same network same interface with load balancing

    - by RushPL
    My setup is two ISPs on a single interface and single network. I can either set my default gateway to 192.168.0.1 or 192.168.1.250 and either work. My desire is to utilize both of them with some load balancing. I have tried to follow the advice given in here http://serverfault.com/a/96586 #!/bin/sh ip route show table main | grep -Ev '^default' \ | while read ROUTE ; do ip route add table ISP1 $ROUTE done ip route add default via 192.168.1.250 table ISP1 ip route add default via 192.168.0.1 table ISP2 iptables -t mangle -A PREROUTING -j CONNMARK --restore-mark iptables -t mangle -A PREROUTING -m mark ! --mark 0 -j ACCEPT iptables -t mangle -A PREROUTING -j MARK --set-mark 10 iptables -t mangle -A PREROUTING -m statistic --mode random --probability 0.5 -j MARK --set-mark 20 iptables -t mangle -A PREROUTING -j CONNMARK --save-mark Now then I do "traceroute somehost" repeatedly I can only get route through my default route which is 192.168.1.250. Shouldn't the packets change routes in a random manner? How to debug it?

  • Network interface selection

    - by Antonino
    Hello. Suppose I have more than a network interfaces and I want to selectively use them per application. eth0 is the standard interface with the standard gateway in the main routing table eth1 is another interface with a different gateway. Suppose I launch an application as a user "user_eth1". I used the following set of rules for iptables / ip rules. IPTABLES: iptables -t mangle -A OUTPUT -m user --uid-owner user_eth1 -j MARK --set-mark 100 iptables -t nat -A POSTROUTING -m user -uid-owner -o eth1 user_eth1 -j SNAT --to-source <eth_ipaddress> IPRULE: ip rule add fwmark 100 lookup table100 and i build "table100" as follows (no doubts on that) ip route show table main | grep -Ev ^default | while read ROUTE; do ip route add table table100 $ROUTE; done ip route add default via <default_gateway> table table100 It doesn't work at all. What's wrong with this? Thank you in advance!

  • Can I lvreduce after lvextend without losing the ext4 partition inside it?

    - by DrSAR
    In a botched attempt to move my root partition from one disk to another I have done the following: added new disk partitioned it with parted (part #3 is now almost totally filling the disk) initialized a physical volume $ pvcreate /dev/sdb3 Physical volume "/dev/sdb3" successfully created extended the volume group to include this new physical disk $ vgextend myvg /dev/sdb3 Volume group "myvg" successfully extended extended the logical volume (I think this is where I ballsed it up: I think I should have pvmove'ed stuff to the new pv in that group - can someone confirm?) $ lvextend /dev/mapper/myvg-root /dev/sdb3 I would now like to undo the lvextend and then proceed with the original plan of moving the content of the old physical volume over to the new physical volume. Can I reduce the logical volume (I have not yet touched the ext4 partition that sits in /dev/mapper/myvg-root with something like resizefs) without fear of damaging the ext4 filesystem? If so, how do I tell it to reduce by exactly the right amount? $ lvreduce --by-exactly-the-amount-occupied-by-PV /ev/sdb3 /dev/mapper/myvg-root

  • Iptable Rule to redirect all traffic requesting a specific domain

    - by user548971
    I'm on a simple linux proxy. I'd like to add iptable rules to drop all requests for a specific domain. I figured I run a dig command to get the ip addresses for the domain and then add an iptable rule for each one. It seems, however, that it doesn't work to bind to more than one ip address. So, it seems I need to add ip ranges like this... iptables -I FORWARD -p tcp -m iprange --dst-range 66.220.144.0-66.220.159.255 --dport 443 -j DROP That seems to work. However, it has proven pretty problematic to parse the output of dig and correctly create the appropriate iptable rules. Is there a better way? Thanks! EV

  • CMOTECH D-50 modem installation in Ubuntu 12.04

    - by Ricardo
    I have recently upgraded from 10.04 to 12.04. I had installed a 3G D-50 modem from CMOTECH. The program for Debian is provided by a Swedish company (ice.net). Usually after some mambo jambo of installung the libg++ libraries requested you can install it and runned in Ubuntu 8.04, 9.04, 10.04 and as far as I know in 11.04. When I upgraded and I click on the icon of ice.net it worked. However, I noticed that the usb D-50 modem was never mounted as usb and it didn't show up in the Lauchnpad or workspace (as when you plug a usb memory stick or another HD). I moved the icon from place in the launchpad and since when I click on the ice.net icon the same message appears: "please plug in your modem". The modem works (I've tested in Windows after this) and it blinks blue (sign that it works and picks up signal). If I type lsusb then I see that Ubuntu sees it on BUS address 006: Bus 006 Device 003: ID 16d8:6803 CMOTECH Co., Ltd. CNU-680 CDMA EV-DO modem I've tried wvdial without success. How can I get the D-50 usb modem mounted as in the previous versions of Ubuntu ?. Any help will be much appreciated. bests. Ricardo

  • A Big Data korszakban, túl az 1000. eladott Oracle Exadata Database Machine adatbázisgépen

    - by user645740
    Mint azt már egy ideje a szél is fújja, beköszöntött a BIG DATA korszak, azaz egyre több adat gyulik, egyre több adattal gazdálkodunk. A hatalmas mennyiségu adat jó részét Oracle adatbázisokban tárolják. Mi is futtathatná jobban, gyorsabban és hetékonyabban ezeket az Oracle adatbázisokat, mint az Oracle stratégiai high-end megoldása az Oracle Exadata Database Machine? Rengeteg forrása van a sok adatnak, néhány példa, ahol a növekedés óriási: kommunikációs adatok, CDR-ek banki és kormányzati tranzakciók hely információk spatial, location, GPS,..., mint ahogyan a közelmúltban az egyes telefonokkal ésoperációs rendszerekkel kapcsolatos "ügyekben" is olvashattuk, e-mail-ek, közösségi site-ok, intelligens méromuszerek, háztartási berendezések, .... Milyen ütemben no az Exadata értékesítés? Nos az Exadata 2008 oszén lett bejelentve. Az Oracle pénzügyi év végén a jelentésben azt olvashatjuk, hogy az Exadata páratlanul sikeres megoldás, már több mint 1000 Exadatát vásároltak meg az Oracle ügyfelek, mondta Mark Hurd, az Oracle alelnöke:   “In addition to record setting software sales, our Exadata and Exalogic systems also made a strong contribution to our growth in Q4,” said Oracle President, Mark Hurd. “Today there are more than 1,000 Exadata machines installed worldwide. Our goal is to triple that number in FY12.” Larry Ellison, az Oracle elso embere, azt nyilatkozta, hogy mind a felho - cloud computing, mind a memória-adatbázisok területén egyre gyorsabban növekszik az Oracle:   “In FY11 Oracle’s database business experienced its fastest growth in a decade,” said Oracle CEO, Larry Ellison. “Over the past few years we added features to the Oracle database for both cloud computing and in-memory databases that led to increased database sales this past year. Lately we’ve been focused on the big business opportunity presented by Big Data.” A Big Data korszakban  megtakarításokat érhetünk el az Exadatával, tekintse meg a következo videót, de óvatosan, mert gondolkodásra késztet:    -   Oracle Exadata: Are You Ready?.

  • 1. születésnap - új tartalom

    - by Lajos Sárecz
    Kb. 1 éve, június elején kezdtem a blogot írni. Az elmúlt egy év alatt 3395 egyedi látogatója volt a blognak, a látogatók alkalmanként átlagosan 59 másodpercet töltöttek el itt. Azt is el kell ismerni, hogy elég nagy a visszafordulási arány (83,5%), azaz az idetévedok kevesebb mint ötöde találja hasznosnak a tartalmat. Ennek persze lehet egy fontos oka, hogy az IT kifejezésekre keresések miatt külföldiek számára is feljön a keresokben a blogom, így csak megnyitva a blogot észlelik, hogy nem értenek magyarul :-). Jól mutatja az alábbi térkép is, hogy a világ számos pontjáról idetalálnak (van aki egyébként használ valami webes fordító megoldást a nyelvi akadály leküzdésére), de az is látszik hogy a célközönséget is sikerül elérni, azaz a látogatók zöme Magyarországról érkezik (3505 látogatás az összes 5082-bol). Érdekes, hogy a legtöbb látogató a "vb tippjáték" (110 látogató) kifejezésre talált ide, ezt követi az "oracle junior képzés" (42), majd a "kyte" (40) (nem biztos hogy Tom Kyte-ra gondoltak :-)). Csupán a 4. helyen áll az elso igazi IT keresés: "oracle workflow" (37), majd "oracle enterprise manager" (33). A napi csúcslátogatást (76) is a vb tippjátékra keresoknek köszönheti a blog... Az 1. születésnap örömére próbáltam valami újítást csinálni. A fejléc alatt látható új menüsorba próbálom összeszedni azokat a hasznos oldalakat, amelyek kapcsolódnak a blog témájához, ám esetleg nem annyira egyszeru rátalálni a weben. Tervezem még ezt tovább bovíteni, esetleg egy külön oldalt is létrehozni erre a célra a blog mögött. Remélem ezzel segítem a blog olvasók munkáját.

  • Do we have enough time to build an electric car future?

    - by julien.groues
    A recent article from Greenbang has posed the question 'Do we have enough time to build an electric car future?'. The writer discusses that, although the future of transport might lie with electric cars, there is concern regarding whether we'll be able to build the market and infrastructure required to support them, before carbon and oil constraints create difficulties in powering the vehicles. Of course, the increasing use of Electric vehicles (EVs) is going to put excessive pressure on energy grids, as large volumes of electricity will need to be directed to charging points, which in turn must handle fluctuating demand at peak times. EVs are increasing in popularity as a sustainable method of transport to reduce carbon consumption, and electric utilities will have the opportunity, and the challenge, to quickly determine the best methods to fuel these vehicles and accommodate the associated increases in demand for energy. Critically, efficient software is required to provide diagnostic and predictive capabilities related to EV refuelling - for example, anticipated electricity flow will need to be addressed as the number of EVs on the road increases, and electricity will need to be directed to specific areas on-demand as vehicles attempt to recharge en-mass. But a smart grid infrastructure can meet these demands, intelligently. The implementation of a smart grid is not in the distant future, it is an achievable reality for utilities via simple installation of new software and technologies, which can be done incrementally for those facing existing legacy systems or concerned with upfront costs. The smart grid is integral to the monitoring and control of energy use as well as the future-proofing of the energy grid. A smart grid will be critical to meeting the electricity requirements of new EVs and will ensure their successful deployment by providing a reliable foundation for the data handling required to record and manage electricity distribution - from recording and assessing energy usage, to analysing data and sharing information with consumers via green billing. http://www.greenbang.com/do-we-have-enough-time-to-build-an-electric-car-future_14248.html

  • PyQt application architecture

    - by L. De Leo
    I'm trying to give a sound structure to a PyQt application that implements a card game. So far I have the following classes: Ui_Game: this describes the ui of course and is responsible of reacting to the events emitted by my CardWidget instances MainController: this is responsible for managing the whole application: setup and all the subsequent states of the application (like starting a new hand, displaying the notification of state changes on the ui or ending the game) GameEngine: this is a set of classes that implement the whole game logic Now, the way I concretely coded this in Python is the following: class CardWidget(QtGui.QLabel): def __init__(self, filename, *args, **kwargs): QtGui.QLabel.__init__(self, *args, **kwargs) self.setPixmap(QtGui.QPixmap(':/res/res/' + filename)) def mouseReleaseEvent(self, ev): self.emit(QtCore.SIGNAL('card_clicked'), self) class Ui_Game(QtGui.QWidget): def __init__(self, window, *args, **kwargs): QtGui.QWidget.__init__(self, *args, **kwargs) self.setupUi(window) self.controller = None def place_card(self, card): cards_on_table = self.played_cards.count() + 1 print cards_on_table if cards_on_table <= 2: self.played_cards.addWidget(card) if cards_on_table == 2: self.controller.play_hand() class MainController(object): def __init__(self): self.app = QtGui.QApplication(sys.argv) self.window = QtGui.QMainWindow() self.ui = Ui_Game(self.window) self.ui.controller = self self.game_setup() Is there a better way other than injecting the controller into the Ui_Game class in the Ui_Game.controller? Or am I totally off-road?

  • Parsing JSON into XML using Windows Phone

    - by Henry Edwards
    I have this code, but can't get it all working. I am trying to get a json string into xml. So that I can get a list of items when i parse the data. Is there a better way to parse json into xml. If so what's the best way to do it, and if possible could you give me a working example? The URL that is in the code is not the URL that i am using using System; using System.Collections.Generic; using System.Linq; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; using Microsoft.Phone.Controls; using Newtonsoft.Json; using Newtonsoft.Json.Serialization; using Newtonsoft.Json.Converters; using Newtonsoft.Json.Utilities; using Newtonsoft.Json.Linq; using Newtonsoft.Json.Schema; using Newtonsoft.Json.Bson; using System.Xml; using System.Xml.Serialization; using System.Xml.Linq; using System.Xml.Linq.XDocument; using System.IO; namespace WindowsPhonePanoramaApplication3 { public partial class Page2 : PhoneApplicationPage { public Page2() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e1) { /* because the origional JSON string has multiple root's this needs to be added */ string json = "{BFBC2_GlobalStats:"; json += DownlodUrl("http://api.bfbcs.com/api/xbox360?globalstats"); json += "}"; XmlDocument doc = (XmlDocument)JsonConvert.DeserializeObject(json); textBox1.Text = GetXmlString(doc); } private string GetXmlString() { throw new NotImplementedException(); } private string DownlodUrl(string url) { string result = null; try { WebClient client = new WebClient(); result = client.DownloadString(url); } catch (Exception ex) { // handle error result = ex.Message; } return result; } private string GetXmlString(XmlDocument xmlDoc) { sw = new StringWriter(); XmlTextWriter xw = new XmlTextWriter(sw); xw.Formatting = System.Xml.Formatting.Indented; xmlDoc.WriteTo(xw); return sw.ToString(); } } } The URL outputs the following code: {"StopName":"Race Hill", "stopId":7553, "NaptanCode":"bridwja", "LongName":"Race Hill", "OperatorsCode1":" 5", "OperatorsCode2":" ", "OperatorsCode3":" ", "OperatorsCode4":"bridwja", "Departures":[ { "ServiceName":"", "Destination":"", "DepartureTimeAsString":"", "DepartureTime":"30/01/2012 00:00:00", "Notes":""}` Thanks for your responses. So Should i just leave the data a json and then view the data via that??? Is this a way to show the data from a json string. public void Load() { // form the URI UriBuilder uri = new UriBuilder("http://mysite.com/events.json"); WebClient proxy = new WebClient(); proxy.OpenReadCompleted += new OpenReadCompletedEventHandler(OnReadCompleted); proxy.OpenReadAsync(uri.Uri); } void OnReadCompleted(object sender, OpenReadCompletedEventArgs e) { if (e.Error == null) { var serializer = new DataContractJsonSerializer(typeof(EventList)); var events = (EventList)serializer.ReadObject(e.Result); foreach (var ev in events) { Items.Add(ev); } } } public ObservableCollection<EventDetails> Items { get; private set; } Edit: Have now kept the url as json and have now got it working by using the json way.
