• How is this problem usually solved without using sever-side scripting?

  - by cyggi

  Simple problem I have so far always solved via PHP: You have a site with header, menu, footer and content field. Header, menu and footer are usually the same for each page. How do you, without PHP or any other server-side language, have the header, menu and footer data exist only in one file? So that for example you don't have ten sites (like home.html, products.html, about.html, ..) all having a copy of the static header and menu in their html files. Now if you want to change the header you have to change ten files. I hope I made my question clear enough, if not please leave a comment :)

• Secondary monitor bug: a problem in WPF or in the graphics driver?

  - by emddudley

  I have discovered a strange bug with my WPF application and I am trying to determine whether it is a problem with WPF or my graphics driver so that I can report it to the appropriate company. I have a Quadro FX 1700 with the latest drivers (197.54) on a Windows XP system, running a .NET 3.5 SP1 application. I have dual monitors, and when I maximize then minimize a child window of the main window on my primary monitor, the child window gets drawn on the secondary monitor as well. It appears in both places. I made a sample application (code is below) which induces this behavior. Start the application and ensure the main window is on your primary monitor. Double-click the main window. A green child window should appear. Click the green child window to maximize. Click the green child window to minimize. Can anyone else reproduce this problem? On my system the green child restores, but then it's drawn on both my primary and secondary monitors, rather than just the primary monitor.

• Improving Partitioned Table Join Performance

  - by Paul White

  The query optimizer does not always choose an optimal strategy when joining partitioned tables. This post looks at an example, showing how a manual rewrite of the query can almost double performance, while reducing the memory grant to almost nothing. Test Data The two tables in this example use a common partitioning partition scheme. The partition function uses 41 equal-size partitions: CREATE PARTITION FUNCTION PFT (integer) AS RANGE RIGHT FOR VALUES ( 125000, 250000, 375000, 500000, 625000, 750000, 875000, 1000000, 1125000, 1250000, 1375000, 1500000, 1625000, 1750000, 1875000, 2000000, 2125000, 2250000, 2375000, 2500000, 2625000, 2750000, 2875000, 3000000, 3125000, 3250000, 3375000, 3500000, 3625000, 3750000, 3875000, 4000000, 4125000, 4250000, 4375000, 4500000, 4625000, 4750000, 4875000, 5000000 ); GO CREATE PARTITION SCHEME PST AS PARTITION PFT ALL TO ([PRIMARY]); There two tables are: CREATE TABLE dbo.T1 ( TID integer NOT NULL IDENTITY(0,1), Column1 integer NOT NULL, Padding binary(100) NOT NULL DEFAULT 0x,   CONSTRAINT PK_T1 PRIMARY KEY CLUSTERED (TID) ON PST (TID) );   CREATE TABLE dbo.T2 ( TID integer NOT NULL, Column1 integer NOT NULL, Padding binary(100) NOT NULL DEFAULT 0x,   CONSTRAINT PK_T2 PRIMARY KEY CLUSTERED (TID, Column1) ON PST (TID) ); The next script loads 5 million rows into T1 with a pseudo-random value between 1 and 5 for Column1. The table is partitioned on the IDENTITY column TID: INSERT dbo.T1 WITH (TABLOCKX) (Column1) SELECT (ABS(CHECKSUM(NEWID())) % 5) + 1 FROM dbo.Numbers AS N WHERE n BETWEEN 1 AND 5000000; In case you don’t already have an auxiliary table of numbers lying around, here’s a script to create one with 10 million rows: CREATE TABLE dbo.Numbers (n bigint PRIMARY KEY);   WITH L0 AS(SELECT 1 AS c UNION ALL SELECT 1), L1 AS(SELECT 1 AS c FROM L0 AS A CROSS JOIN L0 AS B), L2 AS(SELECT 1 AS c FROM L1 AS A CROSS JOIN L1 AS B), L3 AS(SELECT 1 AS c FROM L2 AS A CROSS JOIN L2 AS B), L4 AS(SELECT 1 AS c FROM L3 AS A CROSS JOIN L3 AS B), L5 AS(SELECT 1 AS c FROM L4 AS A CROSS JOIN L4 AS B), Nums AS(SELECT ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) AS n FROM L5) INSERT dbo.Numbers WITH (TABLOCKX) SELECT TOP (10000000) n FROM Nums ORDER BY n OPTION (MAXDOP 1); Table T1 contains data like this: Next we load data into table T2. The relationship between the two tables is that table 2 contains ‘n’ rows for each row in table 1, where ‘n’ is determined by the value in Column1 of table T1. There is nothing particularly special about the data or distribution, by the way. INSERT dbo.T2 WITH (TABLOCKX) (TID, Column1) SELECT T.TID, N.n FROM dbo.T1 AS T JOIN dbo.Numbers AS N ON N.n >= 1 AND N.n <= T.Column1; Table T2 ends up containing about 15 million rows: The primary key for table T2 is a combination of TID and Column1. The data is partitioned according to the value in column TID alone. Partition Distribution The following query shows the number of rows in each partition of table T1: SELECT PartitionID = CA1.P, NumRows = COUNT_BIG(*) FROM dbo.T1 AS T CROSS APPLY (VALUES ($PARTITION.PFT(TID))) AS CA1 (P) GROUP BY CA1.P ORDER BY CA1.P; There are 40 partitions containing 125,000 rows (40 * 125k = 5m rows). The rightmost partition remains empty. The next query shows the distribution for table 2: SELECT PartitionID = CA1.P, NumRows = COUNT_BIG(*) FROM dbo.T2 AS T CROSS APPLY (VALUES ($PARTITION.PFT(TID))) AS CA1 (P) GROUP BY CA1.P ORDER BY CA1.P; There are roughly 375,000 rows in each partition (the rightmost partition is also empty): Ok, that’s the test data done. Test Query and Execution Plan The task is to count the rows resulting from joining tables 1 and 2 on the TID column: SET STATISTICS IO ON; DECLARE @s datetime2 = SYSUTCDATETIME();   SELECT COUNT_BIG(*) FROM dbo.T1 AS T1 JOIN dbo.T2 AS T2 ON T2.TID = T1.TID;   SELECT DATEDIFF(Millisecond, @s, SYSUTCDATETIME()); SET STATISTICS IO OFF; The optimizer chooses a plan using parallel hash join, and partial aggregation: The Plan Explorer plan tree view shows accurate cardinality estimates and an even distribution of rows across threads (click to enlarge the image): With a warm data cache, the STATISTICS IO output shows that no physical I/O was needed, and all 41 partitions were touched: Running the query without actual execution plan or STATISTICS IO information for maximum performance, the query returns in around 2600ms. Execution Plan Analysis The first step toward improving on the execution plan produced by the query optimizer is to understand how it works, at least in outline. The two parallel Clustered Index Scans use multiple threads to read rows from tables T1 and T2. Parallel scan uses a demand-based scheme where threads are given page(s) to scan from the table as needed. This arrangement has certain important advantages, but does result in an unpredictable distribution of rows amongst threads. The point is that multiple threads cooperate to scan the whole table, but it is impossible to predict which rows end up on which threads. For correct results from the parallel hash join, the execution plan has to ensure that rows from T1 and T2 that might join are processed on the same thread. For example, if a row from T1 with join key value ‘1234’ is placed in thread 5’s hash table, the execution plan must guarantee that any rows from T2 that also have join key value ‘1234’ probe thread 5’s hash table for matches. The way this guarantee is enforced in this parallel hash join plan is by repartitioning rows to threads after each parallel scan. The two repartitioning exchanges route rows to threads using a hash function over the hash join keys. The two repartitioning exchanges use the same hash function so rows from T1 and T2 with the same join key must end up on the same hash join thread. Expensive Exchanges This business of repartitioning rows between threads can be very expensive, especially if a large number of rows is involved. The execution plan selected by the optimizer moves 5 million rows through one repartitioning exchange and around 15 million across the other. As a first step toward removing these exchanges, consider the execution plan selected by the optimizer if we join just one partition from each table, disallowing parallelism: SELECT COUNT_BIG(*) FROM dbo.T1 AS T1 JOIN dbo.T2 AS T2 ON T2.TID = T1.TID WHERE $PARTITION.PFT(T1.TID) = 1 AND $PARTITION.PFT(T2.TID) = 1 OPTION (MAXDOP 1); The optimizer has chosen a (one-to-many) merge join instead of a hash join. The single-partition query completes in around 100ms. If everything scaled linearly, we would expect that extending this strategy to all 40 populated partitions would result in an execution time around 4000ms. Using parallelism could reduce that further, perhaps to be competitive with the parallel hash join chosen by the optimizer. This raises a question. If the most efficient way to join one partition from each of the tables is to use a merge join, why does the optimizer not choose a merge join for the full query? Forcing a Merge Join Let’s force the optimizer to use a merge join on the test query using a hint: SELECT COUNT_BIG(*) FROM dbo.T1 AS T1 JOIN dbo.T2 AS T2 ON T2.TID = T1.TID OPTION (MERGE JOIN); This is the execution plan selected by the optimizer: This plan results in the same number of logical reads reported previously, but instead of 2600ms the query takes 5000ms. The natural explanation for this drop in performance is that the merge join plan is only using a single thread, whereas the parallel hash join plan could use multiple threads. Parallel Merge Join We can get a parallel merge join plan using the same query hint as before, and adding trace flag 8649: SELECT COUNT_BIG(*) FROM dbo.T1 AS T1 JOIN dbo.T2 AS T2 ON T2.TID = T1.TID OPTION (MERGE JOIN, QUERYTRACEON 8649); The execution plan is: This looks promising. It uses a similar strategy to distribute work across threads as seen for the parallel hash join. In practice though, performance is disappointing. On a typical run, the parallel merge plan runs for around 8400ms; slower than the single-threaded merge join plan (5000ms) and much worse than the 2600ms for the parallel hash join. We seem to be going backwards! The logical reads for the parallel merge are still exactly the same as before, with no physical IOs. The cardinality estimates and thread distribution are also still very good (click to enlarge): A big clue to the reason for the poor performance is shown in the wait statistics (captured by Plan Explorer Pro): CXPACKET waits require careful interpretation, and are most often benign, but in this case excessive waiting occurs at the repartitioning exchanges. Unlike the parallel hash join, the repartitioning exchanges in this plan are order-preserving ‘merging’ exchanges (because merge join requires ordered inputs): Parallelism works best when threads can just grab any available unit of work and get on with processing it. Preserving order introduces inter-thread dependencies that can easily lead to significant waits occurring. In extreme cases, these dependencies can result in an intra-query deadlock, though the details of that will have to wait for another time to explore in detail. The potential for waits and deadlocks leads the query optimizer to cost parallel merge join relatively highly, especially as the degree of parallelism (DOP) increases. This high costing resulted in the optimizer choosing a serial merge join rather than parallel in this case. The test results certainly confirm its reasoning. Collocated Joins In SQL Server 2008 and later, the optimizer has another available strategy when joining tables that share a common partition scheme. This strategy is a collocated join, also known as as a per-partition join. It can be applied in both serial and parallel execution plans, though it is limited to 2-way joins in the current optimizer. Whether the optimizer chooses a collocated join or not depends on cost estimation. The primary benefits of a collocated join are that it eliminates an exchange and requires less memory, as we will see next. Costing and Plan Selection The query optimizer did consider a collocated join for our original query, but it was rejected on cost grounds. The parallel hash join with repartitioning exchanges appeared to be a cheaper option. There is no query hint to force a collocated join, so we have to mess with the costing framework to produce one for our test query. Pretending that IOs cost 50 times more than usual is enough to convince the optimizer to use collocated join with our test query: -- Pretend IOs are 50x cost temporarily DBCC SETIOWEIGHT(50);   -- Co-located hash join SELECT COUNT_BIG(*) FROM dbo.T1 AS T1 JOIN dbo.T2 AS T2 ON T2.TID = T1.TID OPTION (RECOMPILE);   -- Reset IO costing DBCC SETIOWEIGHT(1); Collocated Join Plan The estimated execution plan for the collocated join is: The Constant Scan contains one row for each partition of the shared partitioning scheme, from 1 to 41. The hash repartitioning exchanges seen previously are replaced by a single Distribute Streams exchange using Demand partitioning. Demand partitioning means that the next partition id is given to the next parallel thread that asks for one. My test machine has eight logical processors, and all are available for SQL Server to use. As a result, there are eight threads in the single parallel branch in this plan, each processing one partition from each table at a time. Once a thread finishes processing a partition, it grabs a new partition number from the Distribute Streams exchange…and so on until all partitions have been processed. It is important to understand that the parallel scans in this plan are different from the parallel hash join plan. Although the scans have the same parallelism icon, tables T1 and T2 are not being co-operatively scanned by multiple threads in the same way. Each thread reads a single partition of T1 and performs a hash match join with the same partition from table T2. The properties of the two Clustered Index Scans show a Seek Predicate (unusual for a scan!) limiting the rows to a single partition: The crucial point is that the join between T1 and T2 is on TID, and TID is the partitioning column for both tables. A thread that processes partition ‘n’ is guaranteed to see all rows that can possibly join on TID for that partition. In addition, no other thread will see rows from that partition, so this removes the need for repartitioning exchanges. CPU and Memory Efficiency Improvements The collocated join has removed two expensive repartitioning exchanges and added a single exchange processing 41 rows (one for each partition id). Remember, the parallel hash join plan exchanges had to process 5 million and 15 million rows. The amount of processor time spent on exchanges will be much lower in the collocated join plan. In addition, the collocated join plan has a maximum of 8 threads processing single partitions at any one time. The 41 partitions will all be processed eventually, but a new partition is not started until a thread asks for it. Threads can reuse hash table memory for the new partition. The parallel hash join plan also had 8 hash tables, but with all 5,000,000 build rows loaded at the same time. The collocated plan needs memory for only 8 * 125,000 = 1,000,000 rows at any one time. Collocated Hash Join Performance The collated join plan has disappointing performance in this case. The query runs for around 25,300ms despite the same IO statistics as usual. This is much the worst result so far, so what went wrong? It turns out that cardinality estimation for the single partition scans of table T1 is slightly low. The properties of the Clustered Index Scan of T1 (graphic immediately above) show the estimation was for 121,951 rows. This is a small shortfall compared with the 125,000 rows actually encountered, but it was enough to cause the hash join to spill to physical tempdb: A level 1 spill doesn’t sound too bad, until you realize that the spill to tempdb probably occurs for each of the 41 partitions. As a side note, the cardinality estimation error is a little surprising because the system tables accurately show there are 125,000 rows in every partition of T1. Unfortunately, the optimizer uses regular column and index statistics to derive cardinality estimates here rather than system table information (e.g. sys.partitions). Collocated Merge Join We will never know how well the collocated parallel hash join plan might have worked without the cardinality estimation error (and the resulting 41 spills to tempdb) but we do know: Merge join does not require a memory grant; and Merge join was the optimizer’s preferred join option for a single partition join Putting this all together, what we would really like to see is the same collocated join strategy, but using merge join instead of hash join. Unfortunately, the current query optimizer cannot produce a collocated merge join; it only knows how to do collocated hash join. So where does this leave us? CROSS APPLY sys.partitions We can try to write our own collocated join query. We can use sys.partitions to find the partition numbers, and CROSS APPLY to get a count per partition, with a final step to sum the partial counts. The following query implements this idea: SELECT row_count = SUM(Subtotals.cnt) FROM ( -- Partition numbers SELECT p.partition_number FROM sys.partitions AS p WHERE p.[object_id] = OBJECT_ID(N'T1', N'U') AND p.index_id = 1 ) AS P CROSS APPLY ( -- Count per collocated join SELECT cnt = COUNT_BIG(*) FROM dbo.T1 AS T1 JOIN dbo.T2 AS T2 ON T2.TID = T1.TID WHERE $PARTITION.PFT(T1.TID) = p.partition_number AND $PARTITION.PFT(T2.TID) = p.partition_number ) AS SubTotals; The estimated plan is: The cardinality estimates aren’t all that good here, especially the estimate for the scan of the system table underlying the sys.partitions view. Nevertheless, the plan shape is heading toward where we would like to be. Each partition number from the system table results in a per-partition scan of T1 and T2, a one-to-many Merge Join, and a Stream Aggregate to compute the partial counts. The final Stream Aggregate just sums the partial counts. Execution time for this query is around 3,500ms, with the same IO statistics as always. This compares favourably with 5,000ms for the serial plan produced by the optimizer with the OPTION (MERGE JOIN) hint. This is another case of the sum of the parts being less than the whole – summing 41 partial counts from 41 single-partition merge joins is faster than a single merge join and count over all partitions. Even so, this single-threaded collocated merge join is not as quick as the original parallel hash join plan, which executed in 2,600ms. On the positive side, our collocated merge join uses only one logical processor and requires no memory grant. The parallel hash join plan used 16 threads and reserved 569 MB of memory:   Using a Temporary Table Our collocated merge join plan should benefit from parallelism. The reason parallelism is not being used is that the query references a system table. We can work around that by writing the partition numbers to a temporary table (or table variable): SET STATISTICS IO ON; DECLARE @s datetime2 = SYSUTCDATETIME();   CREATE TABLE #P ( partition_number integer PRIMARY KEY);   INSERT #P (partition_number) SELECT p.partition_number FROM sys.partitions AS p WHERE p.[object_id] = OBJECT_ID(N'T1', N'U') AND p.index_id = 1;   SELECT row_count = SUM(Subtotals.cnt) FROM #P AS p CROSS APPLY ( SELECT cnt = COUNT_BIG(*) FROM dbo.T1 AS T1 JOIN dbo.T2 AS T2 ON T2.TID = T1.TID WHERE $PARTITION.PFT(T1.TID) = p.partition_number AND $PARTITION.PFT(T2.TID) = p.partition_number ) AS SubTotals;   DROP TABLE #P;   SELECT DATEDIFF(Millisecond, @s, SYSUTCDATETIME()); SET STATISTICS IO OFF; Using the temporary table adds a few logical reads, but the overall execution time is still around 3500ms, indistinguishable from the same query without the temporary table. The problem is that the query optimizer still doesn’t choose a parallel plan for this query, though the removal of the system table reference means that it could if it chose to: In fact the optimizer did enter the parallel plan phase of query optimization (running search 1 for a second time): Unfortunately, the parallel plan found seemed to be more expensive than the serial plan. This is a crazy result, caused by the optimizer’s cost model not reducing operator CPU costs on the inner side of a nested loops join. Don’t get me started on that, we’ll be here all night. In this plan, everything expensive happens on the inner side of a nested loops join. Without a CPU cost reduction to compensate for the added cost of exchange operators, candidate parallel plans always look more expensive to the optimizer than the equivalent serial plan. Parallel Collocated Merge Join We can produce the desired parallel plan using trace flag 8649 again: SELECT row_count = SUM(Subtotals.cnt) FROM #P AS p CROSS APPLY ( SELECT cnt = COUNT_BIG(*) FROM dbo.T1 AS T1 JOIN dbo.T2 AS T2 ON T2.TID = T1.TID WHERE $PARTITION.PFT(T1.TID) = p.partition_number AND $PARTITION.PFT(T2.TID) = p.partition_number ) AS SubTotals OPTION (QUERYTRACEON 8649); The actual execution plan is: One difference between this plan and the collocated hash join plan is that a Repartition Streams exchange operator is used instead of Distribute Streams. The effect is similar, though not quite identical. The Repartition uses round-robin partitioning, meaning the next partition id is pushed to the next thread in sequence. The Distribute Streams exchange seen earlier used Demand partitioning, meaning the next partition id is pulled across the exchange by the next thread that is ready for more work. There are subtle performance implications for each partitioning option, but going into that would again take us too far off the main point of this post. Performance The important thing is the performance of this parallel collocated merge join – just 1350ms on a typical run. The list below shows all the alternatives from this post (all timings include creation, population, and deletion of the temporary table where appropriate) from quickest to slowest: Collocated parallel merge join: 1350ms Parallel hash join: 2600ms Collocated serial merge join: 3500ms Serial merge join: 5000ms Parallel merge join: 8400ms Collated parallel hash join: 25,300ms (hash spill per partition) The parallel collocated merge join requires no memory grant (aside from a paltry 1.2MB used for exchange buffers). This plan uses 16 threads at DOP 8; but 8 of those are (rather pointlessly) allocated to the parallel scan of the temporary table. These are minor concerns, but it turns out there is a way to address them if it bothers you. Parallel Collocated Merge Join with Demand Partitioning This final tweak replaces the temporary table with a hard-coded list of partition ids (dynamic SQL could be used to generate this query from sys.partitions): SELECT row_count = SUM(Subtotals.cnt) FROM ( VALUES (1),(2),(3),(4),(5),(6),(7),(8),(9),(10), (11),(12),(13),(14),(15),(16),(17),(18),(19),(20), (21),(22),(23),(24),(25),(26),(27),(28),(29),(30), (31),(32),(33),(34),(35),(36),(37),(38),(39),(40),(41) ) AS P (partition_number) CROSS APPLY ( SELECT cnt = COUNT_BIG(*) FROM dbo.T1 AS T1 JOIN dbo.T2 AS T2 ON T2.TID = T1.TID WHERE $PARTITION.PFT(T1.TID) = p.partition_number AND $PARTITION.PFT(T2.TID) = p.partition_number ) AS SubTotals OPTION (QUERYTRACEON 8649); The actual execution plan is: The parallel collocated hash join plan is reproduced below for comparison: The manual rewrite has another advantage that has not been mentioned so far: the partial counts (per partition) can be computed earlier than the partial counts (per thread) in the optimizer’s collocated join plan. The earlier aggregation is performed by the extra Stream Aggregate under the nested loops join. The performance of the parallel collocated merge join is unchanged at around 1350ms. Final Words It is a shame that the current query optimizer does not consider a collocated merge join (Connect item closed as Won’t Fix). The example used in this post showed an improvement in execution time from 2600ms to 1350ms using a modestly-sized data set and limited parallelism. In addition, the memory requirement for the query was almost completely eliminated  – down from 569MB to 1.2MB. The problem with the parallel hash join selected by the optimizer is that it attempts to process the full data set all at once (albeit using eight threads). It requires a large memory grant to hold all 5 million rows from table T1 across the eight hash tables, and does not take advantage of the divide-and-conquer opportunity offered by the common partitioning. The great thing about the collocated join strategies is that each parallel thread works on a single partition from both tables, reading rows, performing the join, and computing a per-partition subtotal, before moving on to a new partition. From a thread’s point of view… If you have trouble visualizing what is happening from just looking at the parallel collocated merge join execution plan, let’s look at it again, but from the point of view of just one thread operating between the two Parallelism (exchange) operators. Our thread picks up a single partition id from the Distribute Streams exchange, and starts a merge join using ordered rows from partition 1 of table T1 and partition 1 of table T2. By definition, this is all happening on a single thread. As rows join, they are added to a (per-partition) count in the Stream Aggregate immediately above the Merge Join. Eventually, either T1 (partition 1) or T2 (partition 1) runs out of rows and the merge join stops. The per-partition count from the aggregate passes on through the Nested Loops join to another Stream Aggregate, which is maintaining a per-thread subtotal. Our same thread now picks up a new partition id from the exchange (say it gets id 9 this time). The count in the per-partition aggregate is reset to zero, and the processing of partition 9 of both tables proceeds just as it did for partition 1, and on the same thread. Each thread picks up a single partition id and processes all the data for that partition, completely independently from other threads working on other partitions. One thread might eventually process partitions (1, 9, 17, 25, 33, 41) while another is concurrently processing partitions (2, 10, 18, 26, 34) and so on for the other six threads at DOP 8. The point is that all 8 threads can execute independently and concurrently, continuing to process new partitions until the wider job (of which the thread has no knowledge!) is done. This divide-and-conquer technique can be much more efficient than simply splitting the entire workload across eight threads all at once.

• Keyboard shortcuts are not working when unity plugin in ccsm is disabled?

  - by Pioneer11X

  I am using ubuntu 11.10 with unity 2d , I dont like the unity launcher and use Docky . So , i have created a new seeion and using some tweaking and playing around i have been successful to get rid of the unity launcher and make a perfect interface that i like , but there are two problems .. Keyboard shortcuts not working I had to disable the ubuntu unity plugin in ccsm to get rid of the unity laucher..when it is enabled , i can use the keyboard shortcuts such as alt+tab etc .. But when i disable it , I am unable to use some shortcuts , I can still use some shortcuts like alt+F4 ect. When I maximise a window , it used to show two window (close , maximise , minimize )buttons and title bars So , i set the window decoration in ccsm to !maxvert from any , and it is working fine for most of the time until i try to snsp the window to a side then the title bar just disappears , leaving space between the panel and the window , I cant close this window until i use the alt+mouse to drag it out , because no buttons would be displayed ..

• What is causing my spacebar to randomly stop working?

  - by Chris Billington

  A couple of times a day, I'll be typing something and realise I can't type spaces. Usually the cursor will flicker instead when I press the spacebar, and I can type all other letters as far as I can tell. If I'm in a terminal the cursor turns from a solid square to an empty square until I release the spacebar. For some reason, restarting compiz with alt-F2 compiz fixes it, until it next occurs. I can still copy and paste spaces from sources that already have them, and I can still insert spaces with ctrl-shift-u, 20, enter. This has been happening for a while, since before I upgraded to maverick, but it feels like its beceoming more frequent. There really doesn't seem to be any kind of a pattern to it. I'm using 64 bit ubuntu 10.10 on a system76 panp7 laptop. Any ideas how I might troubleshoot? EDIT: using xev, normally a spacebar registers as: KeyPress event, serial 36, synthetic NO, window 0x5600001, root 0x101, subw 0x0, time 26488647, (88,403), root:(748,458), state 0x10, keycode 65 (keysym 0x20, space), same_screen YES, XLookupString gives 1 bytes: (20) " " XmbLookupString gives 1 bytes: (20) " " XFilterEvent returns: False KeyRelease event, serial 36, synthetic NO, window 0x5600001, root 0x101, subw 0x0, time 26488729, (88,403), root:(748,458), state 0x10, keycode 65 (keysym 0x20, space), same_screen YES, XLookupString gives 1 bytes: (20) " " XFilterEvent returns: False But when it's stopped behaving a press of the spacebar instead gives the three events: FocusOut event, serial 36, synthetic NO, window 0x5600001, mode NotifyGrab, detail NotifyAncestor FocusIn event, serial 36, synthetic NO, window 0x5600001, mode NotifyUngrab, detail NotifyAncestor KeymapNotify event, serial 36, synthetic NO, window 0x0, keys: 2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 FURTHER EDIT: Ok, so I think I've solved the problem, and by that I mean I now know which package to file a bug against. I have a hot corner which initiates a window picker, and I've customised the window picking so that left click goes to a window, right click closes one and spacebar zooms in on one. When I go to this hot corner, compiz must take control of my spacebar, and clearly isn't giving it back when I leave the window picker. So I'll be filing a bug against compiz. reported:here

• Oracle ODP.NET und Windows PowerShell

  - by cjandaus

  In der Microsoft Welt wohlbekannt, in der Oracle Welt nur ein Schulterzucken hervorrufend - die sogenannten Scripting Guys. Wie der Name bereits vermuten lässt, geht es in deren Hey, Scripting Guy! Blog um Scripting. Und damit natürlich um die Windows PowerShell. Ja, die Zeiten des DOS-Kommandofensters und Batch-Dateien ist vorbei. Die PowerShell ist eine mächtige Scripting-Umgebung unter Windows, die selbst unter Unix/Linux-Administratoren Gefallen finden sollte. Dass man damit wunderbar auch auf Oracle Datenbanken zugreifen kann, haben wir bereits vor Jahren in einer Oracle Workshop Reihe bewiesen. Damals begleitete mich Klaus Rohe von Microsoft, der mit mir dann auch gemeinsam einen Vortrag auf DOAG Konferenz hielt. Unser gemeinsames Ziel war es damals wie heute, die Oracle Anwender von der hervorragenden Integration zwischen Oracle, Windows und .NET zu überzeugen. Was lag näher, als sich dies von beiden Herstellern gemeinsam bestätigen zu lassen? Vor allem die ewigen Zweifler begrüßten dies. Seither war die PowerShell bei mir nicht mehr auf dem Radar und auch Oracle Anwender haben das Thema nicht mehr aufgeworfen. Möglicherweise auch deshalb, weil es zu neu oder zu unbekannt ist? Eher unwahrscheinlich ... Vielleicht liegt es vielmehr daran, dass man einfach mal davon ausgeht, dass PowerShell nur für Microsoft Produkte richtig nutzbar ist? Oder man bekommt erzählt, dass nur die Integration mit der Microsoft-eigenen Datenbank SQL Server möglich ist? Und das ist natürlich nicht richtig - so wie immer (ich denke dabei unter anderem an das Microsoft Active Directory - aber dazu ein andermal mehr). Umso mehr freut es mich, einen brandneuen Blog-Beitrag zu genau diesem Thema zu lesen, auf den mich Alex Keh, (Produkt Manager für Windows und .NET im Oracle Headquarter in San Francisco) aufmerksam gemacht hat. Was die Sache noch besser macht, dieser Beitrag stammt aus der Microsoft Welt und belegt damit zwischen den Zeilen, dass die Oracle Datenbank und unsere .NET Integration via dem Oracle Data Provider for .NET (ODP.NET) auch hier eine bedeutende Rolle spielt. In diesem Sinne: Beide Daumen hoch für die Scripting Guys! Der Beitrag nennt sich Use Oracle ODP.NET and PowerShell to Simplify Data Access und trotz ein paar weniger Ausreißer, ist der Artikel sehr zu empfehlen, um in das Thema einzusteigen. Lassen Sie es mich wissen, wie Sie zu dieser Integration stehen, ob die PowerShell für Sie in der Praxis wichtig ist oder werden könnte, und falls Sie Features vermissen, die Oracle künftig umsetzen sollte. Danke!

• How to make multiple Excel files open in ONE window/instance of Excel 2003 in Win 7

  - by Mark

  I'm running Excel 2003 on my new Windows 7 machine. (There is also a Excel 2010 starter pre installed that I do not use). I'm a heavy user of Excel. I use it all day every day. I often have 10 or 15 sheets open and once and many of them have cell references to each other. I also have a macro file that keeps all my short cuts. On my old W2K machine when I clicked on a .xls file or a shortcut to one to it would open that file in the existing instance of Excel. This is as it should be. I would have many files open, in only one "window" or instance of Excel. All the files could interact with each other, the cross file lookups worked, my macros worked and I could switch between workbooks with CTRL Tab or CTRL F6, I could move tabs from one workbook to another. On the new W7 machine clicking on an icon opens a NEW INSTANCE of Excel every time. This is terribly frustrating. None of my connecting spreadsheets work anymore. My macros don't work. I can't connect files, I can't move tabs. I'm stuck. I can't do my work! I can still open files in one instance by doing a CTRL-O and navigating, but I need to my files to work on a click. I'm guessing this is a flaw in the registry files, possibly because of the starter Excel 2010 that came preloaded on my new machine. Can you walk me through a registry edit to fix this bug? Is there an easier way than a registry edit?

• Packets marked by iptables only sent to the correct routing table sometimes

  - by cookiecaper

  I am trying to route packets generated by a specific user out over a VPN.

I am testing ipchicken.com and walmart.com via links, from the same user, same shell. walmart.com appears to use the VPN; ipchicken.com does not. Any help appreciated. Will send 0.5 bitcoins to answerer who makes this fixed.

• Automatically switch to workspace with active application

  - by Pit

  Hi, I currently have 4 workspaces. If I have a pidgin chat window open on one workspace that is currently not active and I get a message in that already open chat window, I want do be able to click on the green envelope symbol in the upper menu-bar and be switched to the workspace the window is situated. Currently if I click on the green envelope symbol there will be appear a button on the lower menu-bar on which I have to click to be switched to the other workspace. Same with opening links. If in some application I click on a link the last activated Firefox window will open the link. Even this last active firebox window is on a currently not active workspace, and there is a Firefox window on the currently active workspace. So either open the link in the Firefox on the currently active workspace, or switch to the workspace on which the link was opened. Is/are there any solution(s) to this problem?

• Open GL polygons not displaying

  I have tried to follow nehe's opengl tutorial lesson 2. I use sfml for my window creation. The problem I have is that both the triangle and the quad don't show up on the screen: #include <SFML/System.hpp> #include <SFML/Window.hpp> #include <iostream> void processEvents(sf::Window *app); void processInput(sf::Window *app, const sf::Input &input); void renderCube(sf::Window *app, sf::Clock *clock); void renderGlScene(sf::Window *app); void init(); int main() { sf::Window app(sf::VideoMode(800, 600, 32), "Nehe Lesson 2"); app.UseVerticalSync(false); init(); while (app.IsOpened()) { processEvents(&app); renderGlScene(&app); app.Display(); } return EXIT_SUCCESS; } void init() { glClearDepth(1.f); glClearColor(0.f, 0.f, 0.f, 0.f); // Enable z-buffer and read and write glEnable(GL_DEPTH_TEST); glDepthMask(GL_TRUE); // Setup a perpective projection glMatrixMode(GL_MODELVIEW); glLoadIdentity(); gluPerspective(45.f, 1.f, 1.f, 500.f); glShadeModel(GL_SMOOTH); } void processEvents(sf::Window *app) { sf::Event event; while (app->GetEvent(event)) { if (event.Type == sf::Event::Closed) { app->Close(); } if (event.Type == sf::Event::KeyPressed && event.Key.Code == sf::Key::Escape) { app->Close(); } } } void renderGlScene(sf::Window *app) { app->SetActive(); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); // Clear the screen and the depth buffer glLoadIdentity(); // Reset the view glTranslatef(-1.5f, 0.0f, -6.0f); // Move Left 1.5 units and into the screen 6.0 glBegin(GL_TRIANGLES); glVertex3f( 0.0f, 1.0f, 0.0f); // Top glVertex3f(-1.0,-1.0f, 0.0f); // Bottom Left glVertex3f( 1.0f,-1.0f, 0.0f); // Bottom Right glEnd(); glTranslatef(3.0f, 0.0f, 0.0f); glBegin(GL_QUADS); // Draw a quad glVertex3f(-1.0f, 1.0f, 0.0f); glVertex3f( 1.0f, 1.0f, 0.0f); glVertex3f( 1.0f,-1.0f, 0.0f); glVertex3f(-1.0f,-1.0f, 0.0f); glEnd(); } I would greatly appreciate it if someone could help me resolve my issue.

• Sometimes new windows don't come to the front when launched

  - by grafthez

  I'm using gnome shell with new ubuntu for few days now and have experienced really annoying behaviour with new windows. Sometimes when I use another window and press e.g. Alt Ctrl T to open new terminal window, I don't get this window being brought to front. Instead I get notification at the bottom that "New terminal window is ready to use". The same is with Pidgin being integrated with gnome shell (via extension). Every time I get new message, window pops up but doesn't show. I need to either Alt Tab it or click the notification. Is there any way to have new windows being always brought to front, and remove those annoying "Window is ready" notifications? UPDATE - gconftool-2 --search-key focus_new_windows (as severin asked): /schemas/apps/metacity/general/focus_new_windows = Schema (type: `string' list_type: '*invalid*' car_type: '*invalid*' cdr_type: '*invalid*' locale: `C') /apps/metacity/general/focus_new_windows = smart

• SSMS Tools Pack 3.0 is out. Full SSMS 2014 support and improved features.

  - by Mladen Prajdic

  With version 3.0 the SSMS 2014 is fully supported. Since this is a new major version you'll eventually need a new license. Please check the EULA to see when. As a thank you for your patience with this release, everyone that bought the SSMS Tools Pack after April 1st, the release date of SQL Server 2014, will receive a free upgrade. You won't have to do anything for this to take effect. First thing you'll notice is that the UI has been completely changed. It's more in line with SSMS and looks less web-like. Also the core has been updated and rewritten in some places to be better suited for future features. Major improvements for this release are: Window Connection Coloring Something a lot of people have asked me over the last 2 years is if there's a way to color the tab of the window itself. I'm very glad to say that now it is. In SSMS 2012 and higher the actual query window tab is also colored at the top border with the same color as the already existing strip making it much easier to see to which server your query window is connected to even when a window is not focused. To make it even better, you can not also specify the desired color based on the database name and not just the server name. This makes is useful for production environments where you need to be careful in which database you run your queries in. Format SQL The format SQL core was rewritten so it'll be easier to improve it in future versions. New improvement is the ability to terminate SQL statements with semicolons. This is available only in SSMS 2012 and up. Execution Plan Analyzer A big request was to implement the Problems and Solutions tooltip as a window that you can copy the text from. This is now available. You can move the window around and copy text from it. It's a small improvement but better stuff will come. SQL History Current Window History has been improved with faster search and now also shows the color of the server/database it was ran against. This is very helpful if you change your connection in the same query window making it clear which server/database you ran query on. The option to Force Save the history has been added. This is a menu item that flushes the execution and tab content history save buffers to disk. SQL Snippets Added an option to generate snippet from selected SQL text on right click menu. Run script on multiple databases Configurable database groups that you can save and reuse were added. You can create groups of preselected databases to choose from for each server. This makes repetitive tasks much easier New small team licensing option A lot of requests came in for 1 computer, Unlimited VMs option so now it's here. Hope it serves you well.

• Missing Firefox app icon

  - by frozenkoi

  I'm using Ubuntu 11.04 (upgraded from LTS 10.04) and Firefox (version 11) doesn't show it's icon in the Window List panel, in the Firefox window top left corner (system menu) nor when using ALT+TAB to switch applications. I'm using unity 2D since I'm running ubuntu as a guest in a VMWare virtual machine (Host is windows 7) Instead of the Firefox icon I get what appears to be a generic icon that looks like an app window in the window list and a black rectangle with a curl in the bottom right corner in the ALT+TAB window. How do I fix this so that the proper Firefox icon gets displayed? EDIT: Depending on the icon set chosen in the Appearence settings window sometimes I get the icon, sometimes I don't. When using Ubuntu classic none of the icon sets provide the icon for Firefox.

• Im getting the "Console Window Host has stopped working" popup in a few places.

  - by m1sk

  Im running Windows 7 on a 17 inch Macbook Pro, late 2011. Last Saturday I opened my laptop(It was either asleep or shutdown before hand) and suddenly had a whole bunch of problem. First off I got a few of pop-errors, my macbook was out of battery. I also had problems with my trackpad(no scrolling or right-click), which I fixed by reinstalling bootcamp. Now a days when ever I run cmd I get the popup Console Window Host has stopped working If I chose the Close the program I get another popup The application was unable to start correctly (0xc0000142) Click OK to close the application. This doesnt happen just with cmd if un/install a program I get similar popups(first one). And in some other case like in visual studio when i was working on class work.

• Why do I get a My Disney window when installing VMWare Workstation?

  - by Marc Esher

  I'm assuming this is a virus, though my virus checker can't find it. I downloaded the latest vmware workstation 7 installer. I'm running Windows 7 64bit. I go to install it, and the installer window is a Disney website. Upon further investigation, what's happening is that the vmware installer extracts/writes a bunch of files to a temp directory. One of those files is an index.htm file. When I open it, sure enough it's the Disney file. I used sysinternals Process Monitor to look for anything fishy, but the only thing I see touching that index.htm file is the vmware installer and explorer.exe

  - by Nate

  In Windows 7, how can I set the default PowerShell window size? By default it comes up too tall for the netbook screen I am working with. I have tried the usual way of changing the size—by clicking in the upper-left corner and choosing “Properties”—but it tells me: Unable to modify the shortcut: . Check to make sure it has not been deleted or renamed. (yes, there is a dot in the middle of the error message) I also tried right-clicking on the PowerShell shortcut in the Start menu and changing properties there, however, the changes don’t seem to stick.

• [xUbuntu] Move a window back into the visible area?

  - by Johan

  Hi I have this annoying little problem on my laptop that sometimes after I have used a external monitor (with higher resolution) some applications place them self outside the visible area of my desktop. So the question is how do I move them back into the visible area? (please note that no part of the window is visible so I can't use the mouse) Is there some app that can give me focus to move a application to the mouse pointer or something like that? Please note that I'm running xUbuntu (xfce) on this laptop. Thanks Johan

• How to prevent dial up networking connection window from coming up on Windows 7?

  - by Tom

  I have PPP over Ethernet connection at home, so I have a dial up connection set up which comes up every time when I log in, so I can connect to the net by clicking on it. This works fine, but now I got a router which does the connection automatically, so there is no need for the dial up networking connecting window to come up. Nevertheless it comes up everytime when I log in regardless of the living net connection already established by the router. It does not cause any error I only have to cancel the dialog, but it's a nuisance and I can't find any setting to make it stop. Of course, I could remove the networking connection altogether, but I'd rather keep it, so I don't have to create it again if sometimes I need to connect to the net directly without the router. Is there a way to stop the connection dialog from coming up without removing the networking connection?

• What would cause a CMD window to open after windows starts?

  - by Carl B

  As of the past few weeks, when I start windows, A CMD window opens and stays open after all the programs and applications launch. I have just been exiting or closing the box, but I have been wondering what would cause it to open in the first place? I have checked to see what is in start up (and I have been looking for CMD or RUN) but I don't see anything out of the ordinary. How can I get this to stop? I have windows 7 Home premium 64.

• Is there a method to export the URLs of the open tabs of a Firefox window?

  - by hekevintran

  If I have a Firefox window open that contains 10 tabs, is there a way in Firefox or by a plug-in to get the URLs of those 10 tabs as a text file or some other format? Right now if I want to do this I need to copy the URL of tab A, paste it somewhere, move to tab B, and repeat. I could also bookmark all the tabs into a folder and export that, but that seems like such a hassle. If there is no such method, could someone point me to some documents that describe the basics of writing a Firefox plug-in. I am willing to write this myself if there is no "standard" way.

• When USB keyboard is plugged in on computer start-up, search results window is being opened multiple times

  - by Dvir Azulay

  As the title says - when my Alienware keyboard is plugged into my laptop during Windows 7 resume from sleep/hibernation, the windows search results and help window (F3, F1 on Windows 7) is being opened multiple times. This behavior won't stop until I pull out one of the two USB connectors this keyboard has. When I plug it back, everything is normal. Also, if I only connect one of the two during Windows resume, it won't happen. Do you have any idea what could cause this weird issue? Edit: Following the feedback on comments suggesting to log my keypress'es during the weird behavior, I've noticed it's actually F1, F2, F3 being spammed in an ordered sequence. Clicking on them manually didn't stop them from repeating.
