• Need to improve the wireless home network

  I am trying to improve the coverage of my home network.

  I have Fios, and with existing wireless features, there are several dead and weak coverage areas in my house.  This is due to a combination of the place where my router's (limited by the power input) and the confuration from home.

  I have CAT - 5 running for most of the rooms, so adding wired devices is not a problem.  I went out and picked up an EA4500 router, and my plan was to convert my Fios router a bridge and then use the EA4500 as the DHCP server.  However, even with this router, my coverage is not improved.  My preferred solution to get 1 or 2 additional access points that I can plug into my cable system, however, I would like to have a common SSID for the network.

  Is a home-based solution available?

  It would be probably better get these access points that you plan to learn to eliminate these "notspots".

  as suggested previously, you can get a WAP610N or one of the new series of EA (set to bridge mode) router.

• Advice needed on improving the system

  Forum of expensive equipment,

  I built a computer 5 years ago (mainly based on the advice of evil ) who has worked for me since then. However, I just built a system (small) (I5, MB: 6.0 Gb/s SATA gates, etc.) to a member of the family and it is so much faster that my old I took him wanted him and decided to upgrade my system.

  My current system:

  1. Motherboard: ASUS P6X68D Premium
  2. Processor: Intel Core i7 930
  3. Chipset: Intel X 58 / ICH10R
  4. Memory: 24 GB (DDR3)
  5. Graphics card: MSI GEFORCE GTX 970 (NVIDIA)
  6. Motherboard ports:
     • 6 x SATA 3.0 Gb/s at HDs 5 and 1 OD
     • SATA 6.0 Gb/s on front eSATA port
     • SATA 6.0 Gb/s to hot box switchable front panel

  (The system is on an individual disk.  E and F are "Work" and "Scratch" each consists of two drives in RAID 0. All discs are 1 TB, SATA II).

  New system (I think):

  1. Motherboard: ASUS Sabertooth X 79 LGA 2011
  2. : Core I7 - 3930K Hexa-Core processor

  Other components of the old system would be used.

  Issues related to the:

  1. This system would be "a lot" faster (not a specific question for a physicist ) than the current one?
  2. I would RAID?
  3. Would be the SSD anywhere (but not all!) in the system to fix even more?

  I would appreciate any advice.

  Thank you

  LACI.

  Of course, it all depends on the budget available, but if I upgrade now an i7-930, these would be my main ingredients:

  • CPU: i7-5930 K or i7-5960 X. Not the i7 - 5820K as suggested above because of the limitation of only 28 PCIe lanes, which closes off the coast of expansion capability.
  • Mobo: Asus X99E-WS
  • Memory: GSkill Ripjaws 4 F4-2666, 32 or 64 GB
  • Disc of BONE: Samsung SM951 SSD, 256 GB m2
  • Extra PCIe card: card PCIe M2 Addonics ADM2X4 for
  • Media / disk cache: Samsung SM951 SSD, 512 GB m2

  and continue to use the GTX970 and the current HDD on SATA 6 G ports. I would certainly like to overclock the CPU at about 4.5 GHz.

  If you have still a few available budget, I would add that some Samsung 850 Pro 1 TB SSD on SATA 6 G ports for media and projects and delegate 1 TB for backup HARD drive.

  That way you can later add another Addonics card when the Samsung SM951 NVMe m2 readers reach 1 TB of capacity and possibly a second GTX without running out of lane PCIe 970. If you were to go in the direction of 'cheap' with the i7 - 5820K, you would have used 16 (video) + 4 (m2), 4 (ADM2X4) = available 28 24 lanes PCIe, leaving no room for a raid controller or a second video card.

  An i7 - 4790K is not an option, because it's only a 4-core, which is only marginally faster than the i7 - 930 (certainly not twice as fast, as claimed in the previous post), he is severely handicapped by only 16 available PCIe lanes used by the video card has no crack m2 on the mobo and you can reuse only 16 GB of your existing RAM except if you have sticks of 3 x 8 GB, in which case you would need one extra to get to 32 GB identical bar. 24 GB is not an option on a mobo 11xx due to the memory controller.

• Newbie question - need to improve the blurred logo

  I have no training in image editing, to help or information would be greatly appreciated.

  My company is trying to get some signs printed with our logo, but the only logo that we have on file is very small, so any re-sizing edges results very blurry. The image is in .png format and dimensions in pixels are by 244 489. From my understanding, this translates a picture about 1.5 "by 3", which is not nearly large enough for our needs. I have gone through the forums looking for methods to increase the resolution of the logo for printing, or to smooth out the edges (this is a pretty basic design), but I do not know what tool would be best. I'm currently downloading the trial of Photoshop to play with him, anyone have advice on where to start?

  Thanks for any help!

  Sonya

  Sonya,

  Vector illustrations are superior to raster work because it is good at any size, instead of being dependent on resolution/size (it create once and use it at any size for any purpose).

  You should take a look at Illustrator or similar application (more) especially designed for the vector illustrations.

  In all cases, there is no way to avoid re-creating the logo and this sample can be used only as a fuzzy model.

  Unless it is possible to dig up the original artwork (vector). It is a genuine attempt to find it.

  For suggestions to recreate the logo, you can display the image in the relevant forums and ask for help.

• BBM BBM needs to improve the features BBM for BB users.

  As my username says, I'm a diehard blackberry user.  While everyone has jumped ship to android, I stayed.  I loved my curve and when she started to speak in tongues (ie. type gibberish, open and close programs on its own, flip between screens) rather than switch to nokia because my rogers plan covered I paitiently waiting for the white Q10.  I still love my Q10.  I feel that BlackBerry makes excellent products that are functional and durable.  However, my problem with Blackberry is in the way they treat loyal customers.

  While all my friends got Galaxy phones... I stayed with my Q10.  When the BlackBerry has launched the bbm4all campaign... I urge all my friends to do despite initial glitches... and now I'm frustrated.  Despite being faithful and have a BB, do my part to help local businesses... I get ads and I am unable to use timed messages or retraction of message, I am unable to create a personalized PIN.  I get constant reminders to the BBM rate, but my opinion on BBM worsens when I get a an announcement from the company in the form of an invitation BBM.

  Despite having a BB and be a loyal user of BB from research in the days of movement... Why do I pay every month to access features such as message retraction which, until the OS update, I got for free?

  I am a student, I don't use BB for his safety, I use my phone to take pictures send SMS, BBMing, check the weather and occasional magic: Realms... I love my Q10 for the physical keyboard and a sleek design... but why blackberry treat BB users and users non - BB as equal?  Apart from the physical keyboard and security, which makes special BB?  BBM was a huge sale for me, when they open to all BB got less than special, but I thought that they would keep him the BBM BBs usage as an improved for the BBM version released for apple and android.  I assumed that this is when I noticed that the video chat was only for conversations from BB to BB.  Although this feature is nice, it is not terribly useful when 80% of your BBM contacts have no BBs.

  I got frustrated when I type wrong message to someone and I can't retract without having to pay a monthly fee.  I've been frustrated when I get ads when I use the BBM instead of Hub app.  I understand that BB is a society and that this money is the priority but why can they not take care of their own?

  My suggestion for Blackberry is to give the BBM BB users with improved features.  Yes, the video call feature is nice, but it isn't terribly important for me.

  For non - usersm BlackBerry BB should do the following:

  • Slightly higher load ^ monthly fee for subscriptions for timed messages/photos
  • Slightly higher monthly fees for subscriptions for retraction of message
  • Require a slightly higher monthly fee for custom pins
  • Slightly higher monthly fees for the removal of ads

  BlackBerry should do the following, as a thank you to those who is loyal as me...

  • Delete subscriptions in the next version of BBM
  • Allow unlimited timed messages and timed free photos
  • Allow the free unlimited message retraction
  • Make pine customized a tax only once
  • Remove ads for free in the next version of BBM

  Due to the ratio of BB users for users non - BB, I think Blackberry skimp on about $24annually * / user BB would be worth when trading for an increase of the customer satisfaction.

  Loyalists slept with Blackberry through everything and I think that the company sometimes forget that without BB users there would not have been a business today.  I think Blackberry users BB treatment does not reflect the dedication that we showed the company and I don't think what is right.  Please like this post if you agree.

  Thank you for your time,

  Haley

  ↑ $1.29, according to a poll of users non - BB in my BBM surveys list was considered a fair price

  * based on privacy and without ads monthly subscription price of $0.99

• Need to improve the performance of oracle query

  Hello
  Currently I wrote the request to get the maximun of XYZ company like this salary
  
  Select the salary of)
  Select the salary of the employee
  where the company = "XYZ".
  salary desc order)
  where rownum < 2;
  
  I thought to replace the same with the following query
  
  Select max (salary)
  the employee
  where the company = "XYZ";
  
  That one will be faster? can you provide some statistical data. It will be good if you share an oracle for this documentation.
  
  Thank you
  Khaldi

  Well, that's your requests, your data contained in your database, on your hardware... Anything that can have an impact. So who better to check if there is no difference in performance than yourself?

  Enable SQL tracing, run the statements, then analyze trace (with the help of tkprof or similar) files and look at the differences.

• Need to remove the space between &lt; af:panelGrouplayout &gt; and &lt; af:panelBox &gt;

  Hi all

  I use JDeveloper 11.1.1.6.

  My scenario is I need to stretch some fields for all browsers, so I use Panel box inside the < f: facet center = name > panelStretchLayout.

  It works very well. But some scenarios need to display the header above the group box elements. Then I try to add panelGroupLayout in < f: facet = top name >. It is stretching very well, but is always to show space between < af:panelBox >.

  How can I remove the space between < af:panelGroupLayout > and < af:panelBox >?

  My Codes like this,

  < af:panelStretchLayout id = "PSL1" inlineStyle = "" margin-top: 30px; ">"

  < f: facet = 'top' name >

  < af:panelGroupLayout id = "pgl4" layout = "vertical".

  inlineStyle = "" background-color: red; ">"

  < af:panelGroupLayout layout = "horizontal" id = "pgl1" >

  < af:outputText value = 'Day' id = "ot1" / >

  < af:outputText value = "Week" id = "ot2" / >

  < af:outputText value = 'Months' id = "ot3" / >

  < af:outputText value = 'Year' id = "ot4" / >

  < / af:panelGroupLayout >

  < / af:panelGroupLayout >

  < / f: facet >

  < f: facet name = "center" >

  < columns af:panelDashboard = rowHeight '1' = "100%" id = "pd1" >

  < af:panelBox id = "pb1" showDisclosure = "false".

  showHeader = "never" > < / af:panelBox >

  < / af:panelDashboard >

  < / f: facet >

  < / af:panelStretchLayout >

  
  

  Thank you...

• HP Pavilion a6000n - improvement of the system. Need help with the decision and suggestions

  Hi all

  I have a HP Pavilion a6000n, spec even with this link , except that I have 3 GB of memory and Window Vista Home Premium 32-bit.

  I think to update some of my computer hardwares that can run more smooth in some games and to improve my gaming experience.

  I'm looking to replace the processor and graphics card.  At the present time, I have an AMD Athlon (TM) 64 X 2 Dual Core Processor 4200 + 2.2 and a NVIDIA Geforce 6150SE nforce 430.

  My price range is around $100-$200 for processor and graphics together.

  I looked at cela processor and graphics card

  They will make a big difference and improvement than what I have at the moment?   If this isn't the case, then can you guys give me some suggestions on the choice of the better ones out there?

  Thank you!

  You have only a 300w ATX PSU (Power Supply Unit), then you will need to update if you plan to install a good graphics card.  Check the manufacturers minimum power required for the card you decide on getting.  As for the CPU, it does not require the upgrade - the graphics card is what causes your performance problems (in the games).  I would like to spend more money on a power supply and graphics card and leave the CPU alon (so far )

• Compacted Outlook Express and save some of my emails. Now, I need access to the following, but can not open them. How to reopen these emails? __

  Compacted Outlook Express and save some of my emails.  Now, I need access to the following, but can not open them.  How to reopen these emails?

  Hi Redtiger1705,

  Lost emails immediately after compact preforming?
  If so, Outlook Express creates BAK files before compaction. They are copied there as a precaution, in case something goes wrong with the compaction. The following steps should help those rear:
  
  1) open Outlook Express and go to tools, Options, maintenance, store folder. Copy the entire path to the storage folder, and then click OK.  Close Outlook Express.

  (2) go to the basket and search for all files with the .bak extension.  Restore the most recent .bak files. That he will put in the OE store folder, but still like a BAK file.

  (3) click on start, run and paste the path that you copied in step 1 in the run box, and then press ENTER.

  4) click Tools, Folder Options. In the Folder Options window, click the view tab.

  (5) less advanced, uncheck the "Hide extensions for known file types".

  (6) you should see the two sent a Sent Items.dbx from the file as well as the Items.bak. Rename the Sent Items.DBX to Sentold.dbx and Rename Items.Bak sent to Sent Items.DBX. When you open OE, your messages sent items must be restored.

  Please let me know if I can be of further assistance!

  Hello

  Graphics (most of them) in the notebooks are soldered to the motherboard and cannot be upgraded. You will need to replace the whole motherboard and also only use compatible system cards. Check out this guide for maintenance and services:
