  • Whats the difference between local and remote addresses in 2008 firewall address

    - by Ian
    In the firewall advanced security manager/Inbound rules/rule property/scope tab you have two sections to specify local ip addresses and remote ip addresses. What makes an address qualify as a local or remote address and what difference does it make? This question is pretty obvious with a normal setup, but now that I'm setting up a remote virtualized server I'm not quite sure. What I've got is a physical host with two interfaces. The physical host uses interface 1 with a public IP. The virtualized machine is connected interface 2 with a public ip. I have a virtual subnet between the two - 192.168.123.0 When editing the firewall rule, if I place 192.168.123.0/24 in the local ip address area or remote ip address area what does windows do differently? Does it do anything differently? The reason I ask this is that I'm having problems getting the domain communication working between the two with the firewall active. I have plenty of experience with firewalls so I know what I want to do, but the logic of what is going on here escapes me and these rules are tedious to have to edit one by one. Ian

  • what's the difference between a Volume and a Partition in Windows 7 diskpart

    - by user170232
    I was trying to follow the Intel guide for setting up iRST (Intel Rapid Start Technology) on my new laptop. The Intel manual says you need to create a *Volume that is as big or bigger than your available memory, set it to a specific id (id=84), then go into the iRST tool and adjust some settings. Looking at the disk manager on the laptop, I see there is already a Partition labeled as "Hibernation Partition" which is a little bigger than the memory in my system. So it looks like iRST was already set up...BUT, it's a Partition, not a Volume. Here's what the manual says to do: (from: http://download.intel.com/support/motherboards/desktop/sb/rapid_start_technology_user_guide.pdf) diskpart list disk select disk x (where x is the disk to use, there's only one disk in this laptop) create partition primary size=X000 (where X000 is the size to create) detail disk (which lists details for the disk. This is where i get hung up) select volume Z (where Z is the *partition you created previously) ** it says the 'detail disk' command will list the volume #, but it doesn't. ** 'detail disk' only lists two "volumes" for Recovery and OS. ** if i do 'list partition', i see the 8 GB *partition labeled as "Hibernation Partition") ** so I can't continue with the following steps: set id=84 override exit The reason I went looking for the manual is because when iRST is enabled in the BIOS, the system won't resume from sleep. When it's disabled, it works fine, but the system goes into (legacy?) Hibernation mode and takes a while to come out of Hibernation. the iRST is supposed to resume from deep sleep very quickly. So, what's the difference between a Volume and a Partition? Should I delete the Hibernation Partition and create a Hibernation Volume? Anyone have any ideas? (if it matters, this is on a Dell XPS 13 with BIOS A08) Thanks! J

  • Difference between accessing a website using Local host and IP address

    - by Cdeez
    I have developed an ASP.NET website and deployed into my IIS server. Now to see that my IIS is installed fine, I type local host in my address bar, and I get the welcome screen of IIS and its documentation in a separate window. Now I gave the url of my website http://localhost/mysites/site2/Default.aspx I access my site. Also giving my IP address instead of local host like: http://192.168.1.46/mysites/site2/Default.aspx also works. Just out of curiosity I wanted to see what happens when I give my IP address in addressbar. It asks me a user name and password saying:The server 192.168.1.46:80 requires a user name and password. I donot know what user name and password it is asking, and as of my knowledge I thought localhost points to my own IP address internally. But what is the difference and also what username and password do I need for it? Update: On chrome and IE just giving localhost displays the welcome screen, but on mozilla, localhost is also asking for a username and password.

  • Officially announced RAM support size doesn't apply to one of twin rigs with just one difference

    - by Deniz
    It'll take a little long to describe my situation but here goes the story : In January 2009 we bought (the OEM parts) two similar systems with just one difference. One of them had a Phenom X4 cpu and the other one (mine) a Phenom X3 cpu. At the beginning we had problems with both systems to power them on whilst having all of their ram slots being full. We decided to install the systems with just 2 slots populated and later try to install the rest of ram sticks. Both systems did succeed to support 3 sticks. We tried many different procedures to make the systems work with their fourth ram slots being populated. We waited for new bios updates and flashed the boards when they were available, we tried different ram sticks with different frequencies etc. One day while we were trying to install the fourth stick, the X4 machine did accept it. The other one did not. The most mind boggling thing was that after one of my trials the X3 system begun to not operate with the third slot populated. Our boards did have AMD 770 chipsets and we even tried to change the board of the X3 machine with another 770 chipset board. Now my questions are : Should we change the cpu ? What is causing the X3 system to not accept the fourth (or now the third) ram stick ? The manufacturers sites do claim that this boards do accept 4 ram sticks (but they only tested them with certain ram brands and models). What are the limitations for maximum ram configurations on motherboards ? Are there some "rules of thumb" except frequency, voltage, chip type considerations for which we did check our parts ? Our boards are : Gigabyte GA-MA770-DS3 Sapphire PC-AM2RX780 - PURE CrossFireX 770

  • Difference in performance: local machine VS amazon medium instance

    - by user644745
    I see a drastic difference in performance matrix when i run it with apache benchmark (ab) in my local machine VS production hosted in amazon medium instance. Same concurrent requests (5) and same total number of requests (111) has been run against both. Amazon has better memory than my local machine. But there are 2 CPUs in my local machine vs 1 CPU in m1.medium. My internet speed is very low at the moment, I am getting Transfer rate as 25.29KBps. How can I improve the performance ?

  • Strange difference in bash behavior across systems

    - by pinkie_d_pie_0228
    I have two systems, an Ubuntu computer and an Android tablet. I have built and configured bash for Android to be used in adb, so it's the same version as my Ubuntu bash, and they use mostly the same bashrc and configuration, and the same exact options set by shopt. However, there is a slight difference in that the Android bash behaves as I expect when I I try to tab-complete something using a variable in it, but the Ubuntu bash doesn't. #Android ls $HOME/loc<tab> => ls $HOME/local #As expected Basically, the variable is taken into account when completing. But then #Ubuntu ls $HOME/loc<tab> => ls \$HOME/loc #Undesired behavior. The list of options is as follows, and is the same in both builds of bash. autocd:checkwinsize:cmdhist:expand_aliases:extglob:extquote:force_fignore:histappend:interactive_comments:progcomp:promptvars:sourcepath What can be making the Ubuntu version escape the $ instead of using it for completion as in the Android build? What can I do to make both work the same way? Any help will be greatly appreciated.

  • DataGrid calculate difference between values in two databound cells

    - by justMe
    Hello! In my small application I have a DataGrid (see screenshot) that's bound to a list of Measurement objects. A Measurement is just a data container with two properties: Date and CounterGas (float). Each Measurement object represents my gas consumption at a specific date. The list of measurements is bound to the DataGrid as follows: <DataGrid ItemsSource="{Binding Path=Measurements}" AutoGenerateColumns="False"> <DataGrid.Columns> <DataGridTextColumn Header="Date" Binding="{Binding Path=Date, StringFormat={}{0:dd.MM.yyyy}}" /> <DataGridTextColumn Header="Counter Gas" Binding="{Binding Path=ValueGas, StringFormat={}{0:F3}}" /> </DataGrid.Columns> </DataGrid> Well, and now my question :) I'd like to have another column right next to the column "Counter Gas" which shows the difference between the actual counter value and the last counter value. E.g. this additional column should calculate the difference between the value of of Feb. 13th and Feb. 6th = 199.789 - 187.115 = 15.674 What is the best way to achieve this? I'd like to avoid any calculation in the Measurement class which should just hold the data. I'd rather more like the DataGrid to handle the calculation. So is there a way to add another column that just calculates the difference between to values? Maybe using some kind of converter and extreme binding? ;D P.S.: Maybe someone with a better reputation could embed the screenshot. Thanks :)

  • Group vs role (Any real difference?)

    - by Ondrej
    Can anyone tell me, what's the real difference between group and role? Ive been trying to figure this out for some time now and the more information I read, the more I get the sence, that this is brought up just to confuse people and there is no proper difference in this. Both can do the other one's job. Ive always used a group to manage users and their access rights. Recently, I've come accross an administration software, where is a bunch of users. Each user can have assigned a module (whole system is split into a few parts called modules ie. Administration module, Survey module, Orders module, Customer module). On top of it, each module have a list of functionalities, that can be allowed or denied for each user. So let's say, a user John Smith can access module Orders and can edit any order, but havent given a right to delete any of them. If there was more users with the same competency, I would use a group to manage that. I would aggregate such users into the same group and assign access rights to modules and their functions to the group. All users in the same group would have the same access rights. Why call it a group and not role? I don't know, I just feel it that way. It seems to me, that simply it just doesnt really matter :] But I still would like to know the real difference. What about you guys? Any suggestions why this should be rather called role than group or the other way round? Thanks to everyone.

  • Find Exact difference between two dates

    - by iPhone Fun
    Hi all , I want some changes in the date comparison. In my application I am comparing two dates and getting difference as number of Days, but if there is only one day difference the system shows me 0 as a difference of days. I do use following code NSDateFormatter *date_formater=[[NSDateFormatter alloc]init]; [date_formater setDateFormat:@"MMM dd,YYYY"]; NSString *now=[NSString stringWithFormat:@"%@",[date_formater stringFromDate:[NSDate date]]]; LblTodayDate.text = [NSString stringWithFormat:@"%@",[NSString stringWithFormat:@"%@",now]]; NSDate *dateofevent = [[NSUserDefaults standardUserDefaults] valueForKey:@"CeremonyDate_"]; NSDate *endDate =dateofevent; NSDate *startDate = [NSDate date]; gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; unsigned int unitFlags = NSDayCalendarUnit; NSDateComponents *components = [gregorian components:unitFlags fromDate:startDate toDate:endDate options:0]; int days = [components day]; I found some solutions that If we make the time as 00:00:00 for comparision then it will show me proper answer , I am right or wrong i don't know. Please help me to solve the issue

  • Determining difference in timestamps for two values in the same MySQL table

    - by JayRizzo03
    I am relatively new to programming in PHP, so I apologize if this is a rather simple question. I have a MySQL database table called MachineReports that contains the following values: ReportNum(primary key, auto increment), MachineID and Timestamp Here is some example data: |ReportNum | MachineID | Timestamp | |1 | AD3203 | 2012-11-18 06:32:28| |2 | AD3203 | 2012-11-19 04:00:15| |3 | BC4300 | 2012-11-19 04:00:15| What I am attempting to do is find the difference in timestamps in seconds for each machine ID by iterating over each row set. I am getting stuck on the best way to do this, however. Here is the code I've written so far: <?php include '../dbconnect/dbconnect.php'; $machineID=[]; //Get a list of all MachineIDs in the database foreach($dbh->query('SELECT DISTINCT(MachineID) FROM MachineReports') as $row) { array_push($machineID, $row[0]); } for($i=0;$i<count($machineID);$i++){ foreach($dbh->query("SELECT MachineID FROM MachineReports WHERE MachineID='$machineID[$i]' ORDER BY MachineID") as $row) { //code to associate each machineID with two time stamps goes here } } ? This code just lists out the contents of the table row by row. My ultimate goal is to find the difference in timestamps for a certain MachineID. One of the things I've considered is using a multidimensional array in php - using the $machineID as the key and then storing the timestamp inside the array the key points to. However, I'm uncertain how to do that since my query parses row by row. I have quite a few questions. 1) Is this the most efficient way to be doing this? I suspect my database table design may not be the best. 2)What would be the best way to determine the difference in timestamps for a certain machineID? Even just a pointer to a topic that would prompt me to think about this in a different way would be helpful - I'm not afraid to do research. Thanks!

  • how is FLUENT api different from other API

    - by intern
    i have come across fluent api while studying DSLs. i have searched alot on FLUENT API..the basic conclusion which i could draw out was that fluent api uses method chaining in order to make the code fluent. but i cannot understand that in object oriented languages we can always create an object and can call the methods related to it. then how is FLUENT api different from it? what other features does fluent api add?

  • Differences between iPhone/iPod Simulator and Devices

    - by Allisone
    Hi, since I started iPhone/iPod Development I have come across some differences between how the simulator and how real device react. Maybe I will come across some other differences I will have to figure out as well, maybe other people haven't met these problems here (YET) and can profit from the knowledge, and maybe you know some problems/differences that you would have been happy to know about earlier before you spent several hours or days figuring out what the heck is going on. So here is what I came across. Simulator is not case sensitive, Devices are case sensitive. This means a default.png or Icon.png will work in simulator, but not on a device where they must be named Default.png and icon.png (if it's still not working read this answer) Simulator has different codecs to play audio and video If you use f.e. MPMoviePlayerController you might play certain video on the simulator while on the device it won't work (use Handbrake-presets-iPhone & iPod Touch to create playable videos for Simulator and Device). If you play audio with AudioServicesPlaySystemSound(&soundID) you might here the sound on simulator but not an a device. (use Audacity to open your soundfile, export as wav and run afconvert -f caff -d LEI16@44100 -c 1 audacity.wav output.caf in terminal) Also there is this flickering on second run problem which can be resolved with an playerViewCtrl.initialPlaybackTime = -1.0; either on the end of playing or before each beginning. Simulator is mostly much faster cause it doesn't simulate the hardware but uses Mac resources, therefore f.e. sio2 Apps (OpenGL,OpenAL,etc. framework) run much better on simulator, well everything that uses more resources will run visibly better in simulator than on device. I hope we can add some more to this.

  • git difftool, open all diff files immediately, not in serial

    - by Seba Illingworth
    The default git diff behavior is to open each diff file in serial (wait for previous file to be closed before opening next file). I'm looking for a way to open all the files at once - in BeyondCompare for example this would open all the files in tabs within the same BC window. This would make it easier to review a complex set of changes; flick back and forwards between the diff files and ignore unimportant files.

  • Array Problem, need to sort via Keys

    - by sologhost
    Ok, not really sure how to do this. I have values that are being outputted from a SQL query like so: $row[0] = array('lid' => 1, 'llayout' => 1, 'lposition' => 1, 'mid' => 1, 'mlayout' => 1, 'mposition' => 0); $row[1] = array('lid' => 2, 'llayout' => 1, 'lposition' => 0, 'mid' => 2, 'mlayout' => 1, 'mposition' => 0); $row[2] = array('lid' => 2, 'llayout' => 1, 'lposition' => 0, 'mid' => 3, 'mlayout' => 1, 'mposition' => 1); $row[3] = array('lid' => 3, 'llayout' => 1, 'lposition' => 1, 'mid' => 4, 'mlayout' => 1, 'mposition' => 1); $row[4] = array('lid' => 4, 'llayout' => 1, 'lposition' => 2, 'mid' => 5, 'mlayout' => 1, 'mposition' => 0); etc. etc. Ok, so the best thing I can think of for this is to give lid and mid array keys and have it equal the mposition into an array within the while loop of query like so... $old[$row['lid']][$row['mid']] = $mposition; Now if I do this, I need to compare this array's keys with another array that I'll need to build based on a $_POST array[]. $new = array(); foreach($_POST as $id => $data) { // $id = column, but we still need to get each rows position... $id = str_replace('col_', '', $id); // now get the inner array... foreach($data as $pos => $idpos) $new[$id][$idpos] = $pos; } Ok, so now I have 2 arrays of info, 1 from the database, and another from the $_POST positions, I hope I got the array keys correct. Now I need to figure out which one's changed, comparing from the old to the new. And also, need to update the database with all of the new positions where new lid = the old lid, and the new mid = the old mid from each array. I'm sure I'll have to use array_key or array_key_intersect somehow, but not sure exactly how...??? Also, I don't think an UPDATE would be useful in a foreach loop, perhaps there's a way to do a CASE statement in the UPDATE query? Also, Am I going about this the right way? OR should I do it another way instead of using a muli-dimensional array for this.

  • Table-level diff and sync procedure for T-SQL

    - by Ville Koskinen
    I'm interested in T-SQL source code for synchronizing a table (or perhaps a subset of it) with data from another similar table. The two tables could contain any variables, for example I could have base table source table ========== ============ id val id val ---------- ------------ 0 1 0 3 1 2 1 2 2 3 3 4 or base table source table =================== ================== key val1 val2 key val1 val2 ------------------- ------------------ A 1 0 A 1 1 B 2 1 C 2 2 C 3 3 E 4 0 or any two tables containing similar columns with similar names. I'd like to be able to check that the two tables have matching columns: the source table has exactly the same columns as the base table and the datatypes match make a diff from the base table to the source table do the necessary updates, deletes and inserts to change the data in the base table to correspond the source table optionally limit the diff to a subset of the base table, preferrably with a stored procedure. Has anyone written a stored proc for this or could you point to a source?

  • Practical differences between classes and structs in .net (not conceptual)?

    - by Gulshan
    Whenever I tried to search about differences between classes and structs in C# or .net, I ended up with the conceptual overview of the two things like value type or the reference type, where the variables are allocated etc. But I need some practical differences. I have found some like different behavior of assignment operator, having constructors etc. Can anybody provide some more practical differences which will be directly useful while coding? Like the things works with one but not with other or same operation showing different behavior. And some common mistakes regarding these two. Also please suggest where to consider using a struct instead of a class. And where the structs should not be used.

  • Python 2.6 and 3.1.1, earlier version compatibility

    - by Todd
    I ordered three books to start teaching myself Python - a beginning programming book, a computer science book that uses Python for all of its code references, and a book on Python network programming. Unfortunately, I was a little too quick on ordering them, because I hadn't noticed the version differences. The beginner book is for python 3.1, the CS book is Python 2.3, and the last is Python 2.6. The CS book is also oriented towards beginners. My question is, will the different versions be too different at this level for me to effectively use all three, or will I likely be able to get by learning from the 3.1 beginners book and then sort of teach myself from the 2.3 CS book, and be able to comprehend 2.6 code? That probably didn't make sense. I hope it did.

  • onDestroy() won't get called after this.finish()

    - by steff
    Hi everyone, I'm wondering why the Motorola Milestone with 2.1-update1 behaves differently from the Emulator or e.g. the Nexus One. I am trying to exit my app with: @Override protected void onPause() { if(mayDestroyActivity) this.finish(); super.onPause(); } This works well on either Emulator or Nexus One. onDestroy() gets called immediatly after onPause() and onStop. But not for the Milestone. Instead, onDestroy() gets called when another Activity is started. Its section in the Manifest looks like this: <activity android:name=".MyActivity" android:configChanges="orientation|keyboardHidden" android:label="@string/questionnaire_item" android:launchMode="singleInstance" android:theme="@android:style/Theme.NoTitleBar.Fullscreen" android:windowSoftInputMode="adjustPan"> <intent-filter> <category android:name="android.intent.category.OPENABLE" /> </intent-filter> </activity> Does anyone have a hint on this? My app depends on exiting properly since I save all progress in onDestroy() Thanks, Steff

  • SQL Server compare table entries for update

    - by Dave
    I have a trade table with several million rows. Each row represents the version of a trade. If I'm given a possibly new trade I compare it to the latest version in the trade table. If it has changed I add a new version, otherwise I do nothing. In order to compare the 2 trades I read the version from the trade table into my application. This doesn't work well when I'm given 10s of thousands of possibly new trades. Even batching reads to read in a 1000 trades at once and compare them the whole process can take several minutes. All the time is spent in the DB. I'm trying to find a way to compare the possibly new trades to the ones in the trade table without so much I/O. What I've come up with so far is adding a hash column to each row in the trade table. The hash is of all the trade fields. Then when I'm given possibly new trades I compute their hash, put the values into a temporary table, then find ones that are different. This feels very hacky. Is there a better way of doing it? Thanks
