'Good form' rules in designing networks
Are there some simple rules (as best practice) witch we must follow in designing LAN?
I debated with a customer’s specialist how to build LAN in his new edifice.
There is a building with the next planned desktop distribution per floor: 50, 40, 130, 50 and about 10 various servers. Customer is a bank.
Client is sure the next structure will satisfy his requirements: as core will be used 3750G-12S + 3750G-48TS (two for each for resilience). On floors there will be groups of two 3560G-48. Each group will be connected with 2 ports Etherchannel to “core”. 3560G in group will be interconnected with CAB-SFP-50CM (Catalyst 3560 SFP Interconnect Cable).
I am sure this is wrong way. But I have only intuition and theoretical arguments.
At first I think the 48:1 oversubscription on wiring closet is too much. I saw somewhere the recommended value is up to 20:1.
Next: for LAN with 250-500 workplaces Cisco recommend using Catalyst 4500 as core. 4500 Supervisors had at least 64Gbps and 48Mpps (Sup-II) and I think it is may be not enough for him. Client solution has 32GB bandwidth (3750 StackWise bus). But may be he’s right? For his 8GB all uplinks speed this is enough?
Has anybody any ideas? May be offer me any useful links, where such questions are discussed.
Take a look at the design guides. They are guide, not hard and fast rules.

I am creating a form on LiveCycle Designer and I am trying to create a form that has a e-mail submit button. When the button is utilized it attaches the form to the e-mail in an plain text .xml format rather than the pdf format. Is there a quick fix?
Hi,
You have the choice between xml or pdf, in later versions of designer you can choose with a dropdown on the email button Object palette, the "Submit As";
In earlier version you had to edit the XML Source and change the format from xml to pdf (or vice-versa);
Regards

Creating PDF forms in LiveCycle Designer 8.0
I post detail at Software
nha khoa Group
Question on a quirk I have noticed when creating a form using LiveCycle Designer 8 and was wondering if there was a way to change this.
I will use a Text Field for an area where I want the person who will fill out the form to add comments/questions. I widen the box out so the user will have area to type their comments in.
In the properties of for that Text Field, on the "Object" tab I check the box to allow multiple lines and I limit the length to the visible area.
That all works fine. The quirk is when I test the form and then click in that area to type for the text field the cursor always starts in the middle of that Text Field area. Is there a way to get the cursor to start at the top of the text box when someone fills out the form?Post your question in the LiveCycle Designer forum.

I'm trying to add an existing field to an existing form in SharePoint Designer 2010. It's a URL to the employee's photo. But each time I try to "Insert as picture" the url to the photo has a trailing comma. Why and more importantly, how do I get
rid of it?
Thanks!Hello,

Renee WHi Renee,
No, you do not have to edit the form from the master page. Master pages do not have forms on them. They define the layout and look-n-feel of a Sharepoint Site.
You said you are adding new column to the list in SPD. Why not in the site itself and then edit the form.?
http://office.microsoft.com/en-001/sharepoint-designer-help/create-a-custom-list-form-using-sharepoint-designer-HA010378258.aspx
Also, check if you master page is checked in and published. If there is content approval on it, it should be approved.

I am running
Windows 7 64 bit
Access 2010 32 bit
Developing an application with a split FE BE with both files local but continue to have the message "Not Responding" when switching from forms view to design view and back as well as if I try to connect to a subform or object on the sub form.I have seen this behavior when the form's RecordSource is a complex query such as a crosstab or a query with several nested queries. To test if this is your case, remove the RecordSource and see if the form starts acting normal again.
Then again, if the form has several subforms they might be slowing up the loading time.

Cannot open form in LifeCycle Designer to edit.
I have created two forms using LC Designer 8. I now need to edit both forms and cannot open them back up to edit!
When I try to open both forms Adobe Professional 8 opens. I then open the form in Adobe Pro 8 and click "edit in designer" and it will not open. I have also tried to open the form directly from my documents in LC Designer and it will not open.
When I try to open LC deigner on its own it will not open - just shoots me straight to Adobe Pro 8.
I need to edit these forms - please help! Thank-you :)I am also having this problem. It is a dynamic form bound to an XML schema. When I try to reopen it, the livecycle banner comes on, but disappears immediately. The pdf opens in acrobat 9 (a 30-day trial copy). From there, it can be distributed and then filled in.

How to add .js link in custom list form through sharepoint designer 2013
hi friends
so far i was adding jquery code to script editor webpart in custom list form.
but i need to know how to add .js link in custom list form through sharepoint designer 2013
please help me.Hi,
We can add the "JS Link Property" in the “WebPart” node in the custom list form page through SharePoint designer 2013.
Here is an example for your reference:
<JSLink xmlns="http://schemas.microsoft.com/WebPart/v2/ListForm">~site/Style Library/js/custom.js</JSLink>
Noticed that, we should not lose the 'xmlns="http://schemas.microsoft.com/WebPart/v2/ListForm' attribute.
Best Regards

Know any good books on OO design in Java?
Can any one recommend a good book on OO design in Java.
I want a book that explains the best practice on method sizes, what to make member varibles or local variables, when to pass parameters, etc...
I have a fair bit of java programming experience, so I don't really want a book for beginners, but one that concentrates on perfecting your OO design skills.
Any recommendations?Some GREAT online resources...

Unable to run Oracle Form Builder from Designer 10g
I am using Windows XP with Oracle Designer 9.0.4.5. From Design Editor, I select Run -> Oracle Forms, nothing happen. I am able to open Form Builder manually (C:\ORACLE\904\bin\ifbld90.exe). After I generated a module (form) from Designer, I have to open the FMB manually from Form Builder. In Designer 9i, I am able to open Form Builder from Designer. Is this a bug for Designer 10g?
Thanks,
JimThanks for the response, Suresh,
I believe this is an installation/configuration issue.
I installed Oracle Developer Suite 9.0.4, which includes Form Builder, Report Builder, and Designer. System Path contains the ORACLE_HOME (c:\oracle\904\bin). I am able to start Form Builder from DOS command (ifbld90.exe). I am also able to start Report Builder (rwbuilder.exe) and Designer (des2k61.exe) from DOS. I am able to Run Oracle Report Builder from Designer, but just not Form Builder. I also checked the Windows registry settings and they seem alright to me.
thanks,

[solved] /etc/udev/rules.d/10-network.rules ignored
Hi.
I have 4 nics (eth0, eth1, eth2, eth3) mapped to MAC addresses in /etc/udev/rules.d/10-network.rules.
Some months ago, I had to symlink /etc/udev/rules.d/80-net-name-slot.rules to /dev/null in order to use these static names.
Now it doesn't work anymore (again and again and again) after a full update (kernel and I assume systemd). The "nic-names" are completely wrong. You call this "predictable". I call this "unpredictable". The only thing which is predictable is that after a kernel update, the network will stop working. It has been that way for months and months ... fortunately I don't update other machines anymore.
Was this non sense really necessary?
Anyway, if you could tell me what to do now to get my network rules applied again, I would really appreciate.
Right now all ethX/MAC are wrong and none of them gets an IP (had to set an IP manually to post here).
* I know what "predictable Network Interface Names" is about. I don't want this bullshit. It's much worse as it used to be. Keep it simple, folks!

But the rules were applied in this case!
It solved the problem described originally. I think I was hit by the race condition after upgrating to kernel 3.8.4-1. This was actually my first 3.8 kernel.
With kernel 3.7, the rules were working even if the devices were named eth0, eth1, etc.
Those names don't work anymore, at least in my case.
Further I created this file for static ips:
# cat /etc/systemd/system/network.service
