  • Scraping &#151 character (long dash) error in Nokogiri

    - by DavidP6
    I having trouble scraping a certain long dash that is encoded as — ; on the Time magazine site. It looks like this: —. It works fine when this dash is encoded as mdash, but when the problem dash is scraped, it is returned as unknown characters. I am using Nokogiri and am wondering if I have to use some sort of special encoding? The page says it is encoded with UTF-8.

  • avoid textarea rows/cols error?

    - by acidzombie24
    I am using a few page validation tools one problem i have is they tell me textarea must have rows and cols attribute. If i am setting this in CSS or using display:none (and using it to hold raw text data) can i do something to skip? it seems like the only answer is rows="0" cols="0" each time i use it. But i have a feeling that is not a good solution.

  • CLI design and implementation?

    - by Majid
    I am developing a time management tool for my personal use. I prefer using keyboard over mouse, and on the interface have a general purpose text box which will act like a command line. I have just started thinking about what commands I need, what to use for the command names, how to pass in switches and parameters, and so forth. I wonder if some of you have come across a good read along these lines; something that describes the choices you have for designing a cli, and how those affect the complexity of the interpreter, and extendability of the commands. It makes no difference if the descriptions are language-specific or in general terms. However, my implementation will be with javascript. Thank you.

  • How to R/W hard disk when CPU is in Protect Mode?

    - by smwikipedia
    I am doing some OS experiment. Until now, all my code utilized the real mode BIOS interrupt to manipulate hard disk and floppy. But once my code enabled the Protect Mode of the CPU, all the real mode BIOS interrupt service routine won't be available. How could I R/W the hard disk and floppy? I have a feeling that I need to do some hardware drivers now. Am I right? Is this why an OS is so difficult to develop? I know that hardwares are all controlled by reading from and writing to certain control or data registers. For example, I know that the Command Block Registers of hard disk range from 0x1F0 to 0x1F7. But I am wondering whether the register addresses of so many different hardwares are the same on the PC platform? Or do I have to detect that before using them? How to detect them?? For any responses I present my deep appreciation.

  • How can I use foreach and fork together to do something in parallel?

    - by kaushalmodi
    This question is not UVM specific but the example that I am working on is UVM related. I have an array of agents in my UVM environment and I would like to launch a sequence on all of them in parallel. If I do the below: foreach (env.agt[i]) begin seq.start(env.agt[i].sqr); end , the sequence seq first executes on env.agt[0].sqr. Once that gets over, it then executes on env.agt[1].sqr and so on. I want to implement a foreach-fork statement so that seq is executed in parallel on all agt[i] sequencers. No matter how I order the fork-join and foreach, I am not able to achieve that. Can you please help me get that parallel sequence launching behavior? Thanks.

  • Check whether a folder is a local or a network resource in .NET

    - by rwmnau
    Is there a quick way to check whether a path I have is on a local disk or somewhere on the network? I can't just check to see if it's a drive letter vs. UNC, because that would incorrectly identify mapped drives as local. I assumed it would be a boolean in the DirectoryInfo object, but it appears that it's not. I've found classic VB code to do this check (through an API), but nothing for .NET so far.

  • error handling in asp.net

    - by user98454
    Hi How can i pass the different types of errors from Data access layer to presentation layer? suppose if we take the northwind database scenario I want to delete the customer, so i selected one customer in ui and clicked the "delete" button.It internally calls the "delete" in data access layer. The prerequisite for deleting the customer is that the customer doesn't have any orders.So in data access layer we wil check whether that customer has any orders.If the customer has orders how can we pass the message from dal to presentation layer that the customer has orders and we don't delete. Am i doing right?is there any other ways to deal with this type? Thanks in advance
