Need advice on choosing the right model

Hello

I bought my first laptop a year before. It's a Dell Studio. Shortly after unpacking, I found there room key problem, so I replaced it with an Inspiron, who just turned the problem of mouse pad.

Now I need to buy a new laptop of a friend and of course Studio and Inspiron are not my choice for known issues. When I did research on the XPS, I found that there are too many graphics and cooling fan problems. Thus, all models of Dell have known problems. What are my options now?

Although Dell warranty offer, complete replacement is valid only up to 20 days. Not to mention the stress returns and replacements.

With these known issues, I'm not ready to pay more than $500 no matter what configuration so that never.

All honest advice or offer will save Dell the passage of my choice to ASUS.

Thank you

Samia

In all honesty, is not a single computer system already in existence that had no "known issues." Everything has known problems. So take with a grain of salt "reports". There is always more complaints than praise on any system. Except for maybe the computers Apple, because they have been known to remove discussions in the forums complaining of problems. It is also interesting to note that many system actually mutually use the parts. Dell uses, in many cases, RAM Samsung, for example. So, sometimes failure is not needed due to the company (Dell, HP, Samsung, etc.), but the OEM of this particular part. Supported products and services is important to consider. How a company handles a problem that a customer is often more important than the cause of the problem in the first place.

I would recommend a XPS if you consider it, but there are a lot of different variables. It would be useful to learn more about what your friend wants a system. If your friend is looking for a laptop with a power, but not looking to be a great player, then I recommend then XPS 12 or XPS 13. The 12 would be with the convertible screen to make a Tablet when necessary. 13 is fine if you are not concerned about the convertible display. Both systems are light and take a small footprint while having a good power behind them.

Important note: I highly recommend to buy a protection plan with cover against accidental damage. It is usually fairly inexpensive, and from personal experience, I can testify to his interest. I have two children and I replaced my system several times during. Of course, it's a pain to have to go through the process, but the pain and hassle is less than having to repurchase all simply a system.

If your friend has specific needs or need a system, or if there is any other questions, let me know and I can do my best to help.

  • VPN requirements, need help in selecting the right technology

    I need help choosing correct vpn technology to meet my needs.

    I have a 2801 router I will use for vpn sessions. I use 871 routers of the series for remote clients. The requirements that make it difficult for me to determine how to configure are:

    The IP WAN routers 871 will be dynamic, so I can't use lan to lan standard IPSEC configuration. The solution must allow the connection of any address.

    Remote sites will also have to pass traffic between remote sites. I need to do this, because this VPN will be used for IP phones and I want clients on remote sites to be able to call each other.

    Some of the solutions I've seen require the remote user enter a user name and password of the CLI on their 871 to bring up the tunnel. If it's possible I don't want it's an addiction.

    I am familiar with cisco routers and can usually do a config works if provided an example, but I don't know enough about the various VPN options to choose the right solution. Any help is greatly appreciated.

    Thank you

    If you need a spoke-to-spoke vpn connection as well, you can try DMVPN.

    I don't think that TO_CHAR can do by itself.  You should maybe call TO_CHAR and then manipulate the output a bit.

    Looks like TO_CHAR with 1 single argument does exactly what you want except when it returns a string starting with a decimal point, in which case you want to concatenate a '0'.  So call TO_CHAR with 1 argument, see if returns the string begins with a decimal point and, if so, put a '0' on it, like this:

    WITH got_str AS

    (

    SELECT n

    TO_CHAR (n) AS str

    FROM the data

    )

    SELECT n

    CASE

    WHAT LIKES str '. %'

    THEN "0". Str

    Of ANOTHER str

    END AS str0

    OF got_str

    ;

    Output:

    STR0 N

    ---------- -----------------------------------------

    0,123.123

    12345678-12345678

    12345678.1 12345678.1234

    12345678.1 12345678.123

    12.0000001 12.00000008

    What do you want for greater than-1 negative numbers?  You may need to make the CASE a little more complicated expression, like this:

    WITH got_str AS

    (

    SELECT n

    TO_CHAR (n) AS str

    FROM the data

    )

    SELECT n

    CASE

    WHAT LIKES str '. %'

    THEN "0". Str

    WHEN the str LIKE '. %'

    THEN '-0 "|" SUBSTR (str, 2)

  • HP pavilion 15-e034tx: how to choose the right RAM for laptop

    How to choose the right RAM for my laptop (Pavilion 15-e034tx). I know I should buy DDR3 ram.

    Are there other factors should I consider when buying one? I got 2 slots for ram, which od these combos are possible?

    1-4 + 4 GB
    2-4 GB + 8 GB
    3-8 GB + 8 GB

    Thank you

    From the Manual:

    Two customer accessible/upgradable memory module slots

    Support for dual channel DDR3L (1600 MHz)

    Support 8192 MB RAM system in the following configurations:

    8192 MB (8192 MB × 1, × 4096 MB 2)

    Manual download link

    See page 53 for instructions. Memory access is easy via the service Panel. This is the part number for the approved 4 HP concert module:

    A 8 GB module is listed in the manual, and it's a 3rd generation of processor i5 I suspect 2 x 8 = 16 concerts would work, but strictly following the manual your only option is to add a 4 GB for a total of 8. Most users really not more 8 GB and adding a second identical module will allow two-channel operation, so you should see a noticeable jump in the overall performance.

  • Choose the right course of training OR + Certification

    Hello

    Hopefully, I'm in the right section of the forum.

    I have some basic knowledge of labview, I created, changed a few screws for hardware equipment such as glasses, food etc, that's when I worked as a trainee.

    Well now, I would like to go for certification OR beginners course (certified associate developer) to advanced (architect) and want to start taking my first step, I need some advice.

    I went through the training information available on the home page and a few questions,

    (1) these courses cover all specific application domain or is a general training, so we can have a bird's-eye view and then apply knowledge in a field interested as (material loop (HIL)), on-board etc.?

    (2) what level of course should start with?

    (3) I want to do an internship, which might be enough to eventually put me on a job in these tough times? What certification do I go to, how much time it usually takes to get enough experience and the examination of the basic certification, the Certified Associate Developerand other developer likeCertified levels and the architect?

    (4) I thought to do strong foundation by taking basic through training courses, OR mount on a project (if I find one) and develop skills in parallel while working and in preparation for certificate exams.

    (5) is there a test by which I could determine, what level I need to start with?

    I look forward to hearing from you of the people onboard, please guide me.

    No and truths don't discourge me :-)

    This might be a post immature, because I'm confused where to start with, please bear with me and answer me

    Kind regards

    Leo

    Hi leo,

    Yes it is possible. If you have spent enough time, then you can definitely get the knowledge needed to pass the certification. You can take the test online and you can print a few examples. There is also a lot of discussions in the forum about the questions and the answers.

    What do you mean with LabVIEW training? If you do a course, the course textbook contains the things you need for certification.

    It will be useful.

  • How to choose the right version of publishing app when you choose to change the image of in InDesign?

    Hi all

    Normally when I want to edit a picture that is in a page layout in InDesign either, I press option-click on the image, or ctrl-click on the image and choose to edit using the CC of Photoshop, Illustrator CC or another app I need to use at any specific time. Well, I also have backups will only backup my entire system and so all my applications get saved as well.

    Well, what's happening now (for today) is that when I choose to edit the image, it is opening Photoshop (or Illustrator, etc) from my drive backup and not within the app on my main drive. So, even though I already have Photoshop open as I work in InDesign, when I try to edit an image it will open the copy of BACKUP of Photoshop AS well I tried to choose 'other' when ctrl-click on the image and choosing to Ed... but when I navigate to the here where Photoshop is on my main drive, I can't choose the main application because it appears to show the main application of Photoshop as a folder with the that there is content packaging.

    How the hell can I fix the path to the correct version of Photoshop, where I need to do the editing? I must now go to things a way hijacked by browsing up to where the image is in the finder (via ctrl-click on the link of the image in the LINKS Panel and choose "show in finder"), but it takes twice longer :((, it wouldn't be so bad if I didn't have as many images as I work with that I'm doing now.

    Any help or advice will be appreciated :))

    Thank you kindly,

    Christine

    Just guessing...

    The problem is if Photoshop CC on the primary drive is open? If this is not the case, consider set to open at the start of the computer. The current instance might prevail over those inactive.

    Usually, the installed in last instance of an application is the one linking operating systems (OS X & Windows) with a document file that calls for the application, for example, by double clicking in Finder/Explorer. It is common to see the new version called (say CC Photoshop rather than Photoshop CS 6) because the new version is usually the last installed. Because Adobe CS applications typically install new versions of common files, it is recommended to install releases in chronological order, if it is necessary to reinstall the applications when there are multiple instances on the same computer. For example, to install Photoshop CS4, and CS5 and CS6; If an earlier version is installed when a newer version is present, the previous common files can cause application problems. One consequence of this is normal, but sometimes annoying, behavior that at the launch of an application by throwing one of his files, the new version is open because this is the functioning of the operating system.

    In your case, it is possible that the operating system sees Photoshop of the backup drive installation the new installation and lance. Perhaps to save Photoshop CC makes this instance appear most recent for the operating system. Remember to leave Photoshop CC out of the backup operation. If it works well! If this isn't the case, you may try to start the computer from the backup disk, run Photoshop, then exit and restart the computer from the main drive. If this solves the problem, maybe try to start from the backup disk, then reinstall Photoshop top and then restarting the main player. If it works, it can "keep", or an operation like backup, could reduce to naught all your smart stuff.

    Maybe one of these strategies may be a permanent solution.

  • Need help to choose the correct setting in the virtual network Editor

    This is my first time using machines virtual period. What I do is implementing a laboratory MCSE to follow certain CBT courses, I bought. I created a team of three virtual machines - two of them that are running WIndows Server 2003 and the other WIndows XP. The lab wants to use the following TCP/IP parameters for the three machines (Server1, Server11 and XP1)

    Server1:

    192.168 1,201

    255.255.255.0

    192.168.1.254

    11 server: 192.168.1.211 (same gateway and subnet as Server1)

    XP1: 192.168.1.1 (ditto for the door and the subnet as Server1)

    Primary DNS is set to 192.168.1.201 (Server1 is DNS server).

    Default VMWorkstation allowed me to ping both servers very well without any additional configuration. My problem is when I try to fix the DNS redirector on Server1. Any DNS server IP address that I plug in I could not get my XP box to get out of the Internet. I know it's a problem with my virtual network settings, I'm sure. Problem is I don't know where to start. Can someone point me in the right direction?

    Thank you!

    General things:

    You cannot use the IP address ranges which are used somewhere else, and that the host might be able to see.

    Type ' ipconfig/all' on the host and the glance to the adapter VMnet8. Suppose you see a 192.168.30.1 there. This means that your network VMnet8 address is 192.168.30.0/24 (24 =, displayed subnet mask as 255.255.255.0).

    Your DNS and gateway for virtual systems would be 192.168.30.2.

    You can check this in the editor of virtual network on the NAT tab.

    To change the range of network addresses VMnet8 you must use the virtual network Editor.

    1. go on 'host Virtual Network Mapping.

    2. click on the ">" beside VMnet8 and choose "subnet".

    3. change address you need. It's the network address, so the last digit (in your case!) should be 0. The address range should not be used elsewhere (physical network, VMnet1).

    4. click on 'apply '.

    5. When you click on the ">" again and choose DHCP or NAT you can see that all addresses have been changed accordingly.

    When you enter ' ipconfig/all' to the host, you will see that the VMnet8 host adapter has an IP address of your selected range with 1 node address (e.g. 192.168.1.1).

    The gateway and the DNS so its node address + 1 (192.168.1.2).

    Are you on a Mac or a PC?

    I don't know if Apple QT Player installation also adds the Apple MJPEG CODEC, as is Apple's CODEC H.264 and a little more. If so, you should have the appropriate CODEC. Also, I don't know if Mac come with Apple MJPEG CODEC installed. Others will have to answer these questions. I have four MJPEG CODEC on my laptop. One was the MainConcept, I bought, installed with Canon G-10 my wife installed with its Lumix, and then there is another, which has probably been installed elsewhere.

    Note how the dimension tables W_PRODUCT_D & W_DAY_D are connected by a Cartesian join before joining the fact W_ORDERITEM_F table using the composite index 'W_ORDERITEM_F_INDX9 '. This index is composed of LAST_UPD_DT_WID, PROD_WID and ACTION_TYPE_WID, which are foreign keys to the dimension tables.

    Now, if I add several tables to the query:
    select count(distinct decode( T30256.HEADER_FLG , 'N' , T30256.ROW_WID ) ) as c1,
                  T352305.DAY_DT as c2,
                   case  when T44643.PRODUCT_CLASS_NAME = 'MobileSubscription' then T40081.ATTR15_CHAR_VAL else 'Unspecified' end  as c3,
                   T30371.X_BT_DLR_GROUP as c4,
                   T352305.ROW_WID as c5
              from                W_PRODUCT_D T30955,
                   W_PRDATTRNM_D T44643,                          
                   W_DAY_D T352305,                  
                   W_ORDERITEM_F T30256,               
                   W_ORDER_D T30371,                                             
                   W_PRDATTR_D T40081                          
              where  ( T30955.ROW_WID = T44643.ROW_WID 
              and T30256.LAST_UPD_DT_WID = T352305.ROW_WID 
              and T30256.PROD_ATTRIB_WID = T40081.ROW_WID 
              and T30256.PROD_WID = T30955.ROW_WID 
              and T30256.ORDER_WID = T30371.ROW_WID 
              and T30955.PROD_NAME = 'Mobile Subscription' 
              and T30371.STATUS_CD = 'Complete' 
              and T30371.ORDER_TYPE = 'Sales Order'  
              and (case  when T44643.PRODUCT_CLASS_NAME = 'MobileSubscription' then T40081.ATTR15_CHAR_VAL else 'Unspecified' end  in ('BT150BB-18M', 'BT250BB-18M', 'BT50BB-18M', 'BT600BB-18M')) 
              and T352305.DAY_DT between TO_DATE('2008-09-27' , 'YYYY-MM-DD') - 7 and TO_DATE('2008-09-27' , 'YYYY-MM-DD') - 1 
             ) 
              group by T30371.X_BT_DLR_GROUP, T352305.ROW_WID, T352305.DAY_DT, 
              case  when T44643.PRODUCT_CLASS_NAME = 'MobileSubscription' then T40081.ATTR15_CHAR_VAL else 'Unspecified' end;
    I added a single table W_ORDER_D to the query and execution plan is:

    Now, CBO choose the composite index and the cost has also increased to 78695. But if I just add a / * + SORTED * / referring to the above query, whereas it should join the dimension tables prior to joining the fact table, then the cost falls to 20913. This means that CBO is not choose the plan with the lowest cost. I tried increasing the optimizer_max_permutations 80000, setting session optimizer_dynamic_sampling level 8 (just to see if it works), but without success.

    Could you please tell how to overcome this problem?

    Thank you very much.

    Hi Randolph,

    The optimizer is set to 'choose', which is the default in 9i. So I guess that CBO uses the "all_rows" mode, because his stats are present.

    According to your advice, I tried to adjust optimizer_mode, first_rows_1, first_rows_10, first_rows_100 and all_rows at the session level, but nothing helped.

    Another question: since you are obviously having a schema star why don't you use not three separate bitmap indexes on the foreign key columns in the fact table? In this way, you can use a transformation star rather than using a composite index.

    You use many OLTP, small, such as transactions that modify your fact table, or is it only loaded by loading in bulk? If you use only loads in bulk index bitmap should be fine.

    Kind regards
