Why the "multiply" and "division" functions are symbolized as well: * and / respectively.

Why they have been modified by their traditional symbols that have been used for centuries and are universally accepted?

The standard computer keyboard is derived from the keyboard terminal teletype, which is in turn derived from a standard typewriter keyboard that did not have these two mathematical operators.

The basic ASCII code set has them nor even if it does not include the more obscure characters like tilde ~ and the hose. characters. Maybe it's partly because computer simply math multiply and divide operators do not exist, either because they exist not on the keyboard, how do you type them.

Once computers started being used in anger operators were necessary but ASCII and keyboards were well defined, an alternative was developed.

  • Why the blocks of temporary tables are placed in the buffer cache?

    I read the following statement, which seems quite plausible to me: "Oracle7.3 and generates from close db file sequential reading of the events when a dedicated server process reads data from temporary segment of the disc." Older versions of Oracle would read temporary segment data in the database buffer cache using db file scattered reads. Releases latest exploit heuristics that data of temporary segment is not likely to be shareable or revisited, then reads it directly to a server process programs global (PGA). »

    To verify this statement (and also for the pleasure of seeing one of these rare close db file sequential read events), I ran a little experiment on my Oracle 10.2 Linux (see below). Not only it seems that different this v above, the blocks of temporary tables are placed in the buffer cache, but also$ BH. OBJD for these blocks does not refer to an object in the database's existing (at least not one that is listed in DBA_OBJECTS). Either incidentally, I traced the session and have not seen any file db close sequential read events.

    So, I have the following questions:
    (1) is my experimental set-up and correct my conclusions (i.e. are blocks of temporary tables really placed in the buffer cache)?
    (2) if so, what is the reason for placing blocks of temporary tables in the buffer cache? As these blocks contain private session data, the blocks in the buffer cache can be reused by another session. So why do all cache buffer management fees to the blocks in the buffer cache (and possibly remove) rather than their caching in a private in-memory session?
    (3) what V$ BH. OBJD consult for blocks belonging to temporary tables?

    Thanks for any help and information
    Kind regards

    The reason to put the blocks to the global temporary table in the buffer cache is the same thing why you put ordinary table blocks in the cache buffers-> you want some of them to be in memory.

    If you ask why don't keep us somehow temporary tables in the PGA - well what happens if this temporary table will be 50 GB? 32-bit platforms cannot even handle this and you do not want a process of becoming uncontrollable so great.

    Moreover, TWG will allow you to restore, back to a backup (or savepoint implied when an error occurs during a call DML), and this requires protection by the cancellation. Place lines / revenge in PGA would have complicated the implementation even further... now GTT is almost of the regular tables which just happened to reside in temporary files.

    If you really want to put data in the PGA only, then you can create collections of PL/SQL and even access through the use of SQL (coll CAST AS xyz_type) where xyz_type is a TABLE of an object any.

  • Why the App Store search function does not work?

    Since the iOS most recent update (9.3.2), the app from the App Store does not work on my iPhone-iTunes app works perfectly, the App Store - space wasted on the screen and memory right now. I tried to disconnect, close the software, restart hard to my phone, but all I get when I try to search is a white screen. I can't even comment to apple in the app because it does not work. It was a time where this kind of thing never happened but the versions of software with major bugs is becoming more of a recurring theme lately. I'm really starting to wonder if Apple jumps right away even the most basic of pre-tests prior to publication just to get out a release. Frustrating to say the least.

    The search function on the App store on my phone work if something is wrong with your system. Try to reset the App Store in the following order:

    Close the App Store completely from the window of the selector app by double clicking the Home button and slide up the App Store preview pane until it disappears from the display. Then sign out of the iTunes Store (in the settings).

    Then perform a forced reboot. Hold down the Home and Sleep/Wake buttons simultaneously for about 15-20 seconds, until the Apple logo appears.

    Then reconnect to the iTunes Store.

  • Buy list HCL SATA or SAS SSD?  Why the consumer grade SATA SSD are meaningless.

    Hello

    I run a node 4 VSAN 6 Cluster with a LSI SAS in Raid-0 Mode controller listed HCL (a 975 queue depth) to which I currently attached: 3 x 10 k SAS Enterprise RPM hard drives and 1 x Samsung 850 SATA Pro 512 GB SSD. The nodes are the same.

    These SSD is due to budgetary constraints. I too put in service the SSD 512 GB to 400 GB and they seem to controllers and BIOS as 400GO devices.

    Performance is horrible. Overall, VM feel morose.

    When you make a copy of a file of DVD ISO file (say 3GB) on one virtual computer to another, I get extremely high 100 MS to 300ms or even higher disk latencies on both virtual machines. When a regeneration occurs because I take a node in Maint.mode with 'full datamigration', or I re - apply a strategy of backup to say "band bandwidth 2" to "stripe-width 3", the whole cluster crushed essentially to a halt. " VM has become so slow and on Linux VM I get same kernel-messages on scsi timeouts, etc. None of the work of the virtual machine, they freeze and basically die because "the disc is extremely unresponsive.

    I'm not alone in this. I have read many similar stories on the net and it often comes down to the 'consumer grade SATA SSD' who these Samsungs are after all.

    I guess I have the same problem.

    My question is this: I have the right to replace the Samsung 850 Pro with either a SAS disk SSD Sandisk which is listed HCL * or * using Intel DC S3700 SATA SSD that are also in the HCL currently for 6 VSAN.

    What I don't understand is: ' if the SATA SSD that I use currently, form a bottleneck due to the depth of the SATA Interface of 32 queue, how can we * all * SATA SSD be on the HCL at all?

    I doubt that these Intel DC S3700 are much faster than the Samsung 850 Pro and they are two SATA drives and they both have a personal 32 queuedepth and all the interface SATA has a 32 port queuedepth pro. So how can disks SATA works in a system of VSAN. I just makes no sense.

    Everyone is to fight to death on "queue-depth queue depth queue depth. Cormac Hogan, Duncan Epping, everyone who is an authority on VSAN. A queue-depth too low controllers were thrown out of the HCL etc etc etc

    When I look at the SSD Intel S3700 HCL wrote:

    Mandatory features:Drive performance, disc reliability, queue depth, SMART SATA Surprise Power Removal, trim attributes / Unmap, Cache write, write the NDR

    It says "tail-depth" as one of the requirements that responds to this SDS. But SATA, by definition, has a maximum queue-depth 32 which is much too small. So, how can it meet "tail-depth"? It is SATA!

    The Intel DC S3700 would cost me about half of the money the SAS SSD Sandisk and of course, if Intel is going to solve my problems of performance, then I'll take those. But if I'm just as much trouble afterwards because of the queue depth of the SATA Interface of 32, then I better invest in the SAS SSD (but which could exhaust my budget for other things so I'd rather not).

    Anyone can shed some light on this?

    (edit: I changed the title to better reflect my findings)

    Update: I bit the bullit, obtained a second mortgage, said my child may not be able to go to College and I bought the SAS SSD (Sandisk 200 GB 6 G SAS). In each of the four nodes, I did a complete data migration, replaced the Samsung 850 Pro SATA SSD with the SSD SAS and macaroni holy, all my problems disappeared.

    The whole system feels much more receptive and do things like clone a virtual machine (which would grind the whole cluster to stop) never stops working like nothing happens.

    Before, when I did a simple copy of an ISO to a virtual computer DVD file to another, I would like to get, maybe, 20 MB/s and the entire cluster has started feeling lethargic until the copy job is completed. Now, I get speeds ranging from 80 to 90 MB/s and so bright and responsive.

    What a difference!

    I'm a very happy man.

    Moreover, my network is a 1 Gbps where each node has two NIC in a LACP LAG and I can clearly see a node to talk to another network node 1 NIC and talk to another node on the other card NETWORK LACP nicely splits the traffic on the two cards.

    The system feels so fast now and reconstructions / present a new application of storage policies is difficult to have an impact, and generally occur much more quickly than before.

    And really, the only thing I did was swap the Samsung 850 Pro SATA SSD with these SAS SSD.

    Lesson learned: either pay the money of the SAS SSD (which are on the HCL, of course) who is the best, or get certified company VSAN grade SATA SSD but STAY AWAY to consumers rank of SATA SSD because they do not have what it takes. They cannot empty their queues fast enough and all clutter as soon as there is a bit of the system load.

    Just don't do it. Forget the consumer SATA rank. It's like throwing money down the toilet. I've been there and I learned the hard way. Let me be the stubborn donkey, so you don't ;-)

  • Why the NDP module says "you are not allowed for this operation?"

    Hello world

    I hope you can help me with this problem!

    I'm playing with the NDP module has a message saying 'you are not allowed for this operation.

    This happens when I try to create a new project and try to open the window to select a project type. It also happens when I go to the ADMIN and add new types of projects?

    Is there a role limiting me or does some other underlying problem?

    Thank you in advance.

    Hello

    I think that you might miss an active project type category.

    Go to Admin-> NDP-> categories of project types.

    You must have at least one category that is active (which is indicated by a green check mark).

    Once at least one is activated, you will need to go to the Cache and rinse the taxonomy of cache (just to be sure, I would empty Admin Data Cache Group as well).

    Then you can go to the Admin and configure your project types.

    Let me know if you have any questions,

  • Why the Pages and Numbers do not use the default printer?

    Recently, I added a second printer to my home network and selected as the default printer. But when I try to print, the correct printer is selected in the dialog box print only part of the time and apparently depends on which application to print from. I believe that Safari, Mail, Contacts and calendar properly use the default printer, then the Pages and Numbers and instead do not the old printer unless I have change the selection in the dialog box impression every time I print.

    How can I get Pages and Numbers to correctly use the right default printer?

    The problem that is happening on my machine (OS X El Capitan 10.11.2, 5.6.1 Pages and numbers 3.6.1) and my wife (running Maverick 10.7.5, Pages ' 08 3.0.3 and Numbers ' 08 1.0.3) and has persisted through a reboot. The old printer is a HP OfficeJet Pro 8600, accessible via WiFi. The new printer is a Brother MFC-7340 connected by USB to a Time Capsule that is accessible via WiFi.

  • Why the names of my chapters are not displayed in the table of contents?

    Hello. I use Indesign & DPS simple editing to make an application. In Indesign, I created several different documents that I used to make items that I put together in a Folio.  I saw it using the tool preview Adobe & on the iPad using Adobe Content Viewer. When I select the button table of contents I see thumbnail screenshots of the first page of each chapter, but no text chapter name.  For each of the documents that I used to make items that I named them after the chapter they represent, which is what I thought each chapter name defined.

    The strange thing is that before I did a couple of test folios and they do not have the name of chapter text. So what can I do to display the chapter name in the table of contents?

    Also, is there a way to change change the thumbnail used by the table of contents?

    Thank you

    The answer to both questions is in the Article Properties dialog box. Select the item in the Folio Builder Panel and choose Properties from the context menu. Specify the name of the chapter of "Title" - which is probably empty now. (There is a difference between an article name and a title of the article. The name is used for internal purposes, such as the binding, and the title appears in the application).

    At the bottom of this dialog box, you see a preview of the Table of contents. Click the folder icon and specify a PNG of 70 x 70 that you design.

    The first attempt to start seems to stall after the first Windows will appear and the monitor did his normal black screen.   A manual power off is required.  The second attempt to start Windows 10 Home functions correctly.  This on a MacBook with OS X installed 10.7.5 late 2006.  This MacBook as the host has Oracle VM in VirtualBox for Mac installed with Windows 7 Home, Windows 7 Pro and Linux Mint installed 17.2 as guests.  All these operating systems work relatively well.  Only two boot problem with Boot Camp is unusual.
