  • Corsair SSD appears completely blank and does not retain written data

    - by ebanders
    I have a 180GB Corsair SSD (model# CSSD-F180GB2-BRKT) as the primary drive in a Windows laptop. Recently the machine became unbootable after installing Windows updates. Windows installed updates before the machine shut down and the next time the machine boot up it complained about not being able to find a bootable device. After finding fixmbr unsuccessful at making the machine unbootable, I investigated a little within knoppix. Fdisk revealed an empty partition table. A scan by Testdisk came up empty. And finally 'head -c 1024 | hd' reveals all zeros. Creating a primary partition spanning the whole disk completes successfully, but after a reboot the disk appears empty again. dmesg reveals no read or write errors. smartctl indicates that the drive is healthy- although the SMART attribute values do not appear to be read properly. "Data Page | WARNING: PREVIOUS ATTRIBUTE HAS TWO" and "Threshold Page | INCONSISTENT IDENTITIES IN THE DATA" messages appear within the table of values. I don't have much experience with SSDs. Is this drive dead or something? Can anyone recommend any diagnostic tools that may be suited for diagnosing SSDs?

  • Android SQLite: nullColumnHack parameter in insert/replace methods

    - by poke
    The Android SDK has some convenience methods for manipulating data with SQLite. However both the insert and replace methods use some nullColumnHack parameter which usage I don't understand. The documentation explains it with the following, but what if a table has multiple columns that allow NULL? I really don't get it :/ SQL doesn't allow inserting a completely empty row, so if initialValues is empty this column [/row for replace] will explicitly be assigned a NULL value

  • How much abstraction is too much?

    - by Daniel Bingham
    In an Object Oriented Program: How much abstraction is too much? How much is just right? I have always been a nuts and bolts kind of guy. I understood the concept behind high levels of encapsulation and abstraction, but always felt instinctively that adding too much would just confuse the program. I always tried to shoot for an amount of abstraction that left no empty classes or layers. And where in doubt, instead of adding a new layer to the hierarchy, I would try and fit something into the existing layers. However, recently I've been encountering more highly abstracted systems. Systems where everything that could require a representation later in the hierarchy gets one up front. This leads to a lot of empty layers, which at first seems like bad design. However, on second thought I've come to realize that leaving those empty layers gives you more places to hook into in the future with out much refactoring. It leaves you greater ability to add new functionality on top of the old with out doing nearly as much work to adjust the old. The two risks of this seem to be that you could get the layers you need wrong. In this case one would wind up still needing to do substantial refactoring to extend the code and would still have a ton of never used layers. But depending on how much time you spend coming up with the initial abstractions, the chance of screwing it up, and the time that could be saved later if you get it right - it may still be worth it to try. The other risk I can think of is the risk of over doing it and never needing all the extra layers. But is that really so bad? Are extra class layers really so expensive that it is much of a loss if they are never used? The biggest expense and loss here would be time that is lost up front coming up with the layers. But much of that time still might be saved later when one can work with the abstracted code rather than more low level code. So when is it too much? At what point do the empty layers and extra "might need" abstractions become overkill? How little is too little? Where's the sweet spot? Are there any dependable rules of thumb you've found in the course of your career that help you judge the amount of abstraction needed?

  • .NET SerialPort DataReceived event thread interference with main thread

    - by Kiran
    I am writing a serial communication program using the SerialPort class in C# to interact with a strip machine connected via a RS232 cable. When i send the command to the machine it responds with some bytes depending on the command. Like when i send a "\D" command, i am expecting to download the machine program data of 180 bytes as a continous string. As per the machine's manual, it suggests as a best practice to send an unreognized characters like comma (,) character to make sure the machine is initialized before sending the first command in the cycle. My serial communication code is as follows: public class SerialHelper { SerialPort commPort = null; string currentReceived = string.Empty; string receivedStr = string.Empty; private bool CommInitialized() { try { commPort = new SerialPort(); commPort.PortName = "COM1"; if (!commPort.IsOpen) commPort.Open(); commPort.BaudRate = 9600; commPort.Parity = System.IO.Ports.Parity.None; commPort.StopBits = StopBits.One; commPort.DataBits = 8; commPort.RtsEnable = true; commPort.DtrEnable = true; commPort.DataReceived += new SerialDataReceivedEventHandler(commPort_DataReceived); return true; } catch (Exception ex) { return false; } } void commPort_DataReceived(object sender, SerialDataReceivedEventArgs e) { SerialPort currentPort = (SerialPort)sender; currentReceived = currentPort.ReadExisting(); receivedStr += currentReceived; } internal int CommIO(string outString, int outLen, ref string inBuffer, int inLen) { receivedStr = string.Empty; inBuffer = string.Empty; if (CommInitialized()) { commPort.Write(outString); } System.Threading.Thread.Sleep(1500); int i = 0; while ((receivedStr.Length < inLen) && i < 10) { System.Threading.Thread.Sleep(500); i += 1; } if (!string.IsNullOrEmpty(receivedStr)) { inBuffer = receivedStr; } commPort.Close(); return inBuffer.Length; } } I am calling this code from a windows form as follows: len = SerialHelperObj.CommIO(",",1,ref inBuffer, 4) len = SerialHelperObj.CommIO(",",1,ref inBuffer, 4) If(inBuffer == "!?*O") { len = SerialHelperObj.CommIO("\D",2,ref inBuffer, 180) } A valid return value from the serial port looks like this: \D00000010000000000010 550 3250 0000256000 and so on ... I am getting some thing like this: \D00000010D,, 000 550 D,, and so on... I feel that my comm calls are getting interferred with the one when i send commands. But i am trying to make sure the result of the comma command then initiating the actual command. but the received thread is inserting the bytes from the previous communication cycle. Can any one please shed some light into this...? I lost quite some hair just trying to get this work. I am not sure where i am doing wrong

  • Ruby concatenate strings and add spaces

    - by David Oneill
    I have 4 string variables name, quest, favorite_color, speed that might be empty. I want to concatenate them all together, putting spaces between those that aren't empty. So: name = 'Tim' quest = 'destroy' favorite_color = 'red' speed = 'fast' becomes 'Tim destroy red fast' and name = 'Steve' quest = '' favorite_color = '' speed = 'slow' becomes: 'Steve slow' (Notice: there is only 1 space between 'Steve' and 'slow') How do I do that (preferably in 1 line).

  • Regex with all optional parts but at least one required

    - by Alan Mendelevich
    I need to write a regex that matches strings like "abc", "ab", "ac", "bc", "a", "b", "c". Order is important and it shouldn't match multiple appearances of the same part. a?b?c? almost does the trick. Except it matches empty strings too. Is there any way to prevent it from matching empty strings or maybe a different way to write a regex for the task.

  • jQuery multiple running totals

    - by Benjamin Randal
    0I am using jQuery to calculate a running total on multiple textboxes. Just found an awesome response on how to get that working a few days ago, but now I am running into another problem. When using one selector, the total for GetTotal is calculated perfectly. However, when I include the second selector, the totals begin to conflict with one another, and no longer calculate properly. I have been searching for a solution to this for some time now, does anyone have any ideas? Here is the selector i am currently using: function GetTotal(txtBox) { var total = 0; $('input:text').each(function(index, value) { total += parseInt($(value).val() || 0); }); $("#chkTotal").html(total); } My view uses these txt boxes <div class="editor-field"> @Html.TextBox("Field1", String.Empty, new {InputType = "text", id = "field1", onchange = "GetTotal(this)" }) </div> <div class="editor-field"> @Html.TextBox("Field2", String.Empty, new {InputType = "text", id = "field2", onchange = "GetTotal(this)" }) </div> <div> <h3>Total Checked</h3> </div> <div id="chkTotal"></div> Now I am trying to implement another selector which will total two additional editor fields... function GetTotal1(txtBox) { var total1 = 0; $('input:text').each(function (index, value) { total1 += parseInt($(value).val() || 0); }); $("#disTotal").html(total1); } View: <div class="editor-field"> @Html.TextBox("Field3", String.Empty, new {InputType = "text", id = "field3", onchange = "GetTotal1(this)" }) </div> <div class="editor-field"> @Html.TextBox("Field4", String.Empty, new {InputType = "text", id = "field4", onchange = "GetTotal1(this)" }) </div> <div> <h3>Total Distributed</h3> </div> <div id="disTotal"></div>

  • Understanding Haskell's filter

    - by dmindreader
    I understand that Haskell's filter is a high order function (meaning a function that takes another function as a parameter) that goes through a list checking which element fulfills certain boolean condition. I don't quite understand its definition: filter:: (a->Bool)->[a]->[a] filter p [] = [] filter p (x:y) | p x = x:filter p y | otherwise = filter p y I understand that if I pass an empty list to the function, it would just return an empty list, but how do I read the last two lines?

  • Does add() on LinkedBlockingQueue notify waiting threads?

    I have a consumer thread taking elements from a LinkedBlockingQueue, and I make it sleep manually when it's empty. I use peek() to see if the queue empty because I have to do stuff because sending the thread to sleep, and I do that with queue.wait(). So, when I'm in another thread and add()an element to the queue, does that automatically notify the thread that was wait()ing on the queue?
