Internet Explorer Local Storage

I have a application which works great on all browsers but IE. I am using the local database provided with HTML5. I need to store 3 attributes for the users of the application. I know in IE I can't use the database approach and I was thinking of using 3 arrays stored in local storage, one array for each attribute. Is there a better (and easier) way of doing this?



Thanks



For example, I want to store 1) destination 2) where they are from 3) date
So I was thinking I will store an array for destinations, an array fro from locations and an array for dates. Then using some id I can index the arrays and get the corresponding information.





Partially missing gridlines on log-scale charts in Excel 2007

I'm using Excel 2007 to create a log-scale chart of numbers (specifically the Zimbabwean dollar exchange rate) over time. I'm using an x-y scatterplot and noticing one odd quirk.



The range of y values (numbers) spans a factor of about 10^30. On every chart I make using this data, half the gridlines are missing. Specifically, only the gridlines corresponding to the largest values show up. In fact, regardless of the total range only the top factor of 10^13 or so have gridlines. This is not dependent on the log base.



Am I doing something wrong? Is this a known bug? I can't find any references to this issue on google or microsoft's bug reports.





Selenium Testing in Hudson question

I'm having some trouble running a simple selenium test through Hudson.



I've installed the SeleniumHQ plugin for Hudson and configured a job to run a simple test suite which consists of two tests which run fine from the Selenium IDE and from the TestNG plugin in Eclipse.



However, when I try to run them through Hudson, the testing just seems to stall at the end of the first test (regardless of which test it is, I've tried many different ones which are all valid when ran in other enviornments).



The Console Output from Hudson reads as follows:




11:48:09.543 INFO - Java: Sun Microsystems Inc. 14.2-b01
11:48:09.544 INFO - OS: Windows Vista 6.0 x86

11:48:09.825 INFO - Preparing Firefox profile...
11:48:12.046 INFO - Launching Firefox...
11:48:12.919 INFO - Checking Resource aliases


The strange thing is, I can see the first test being ran, and it passes but selenium then doesnt skip onto the next one, and if I create a test suite with just the one test, it simply hangs there indefinitely. Please note that I have an AssertVisible action in the test to check the validity of the results. Do I need to return anything else for Hudson to run the test properly?



Thanks in advance for any help on this...

Android Asset Packaging Tool

Usage:
aapt l[ist] [-v] [-a] file.{zip,jar,apk}
List contents of Zip-compatible archive.

aapt d[ump] [--values] WHAT file.{apk} [asset [asset ...]]
badging Print the label and icon for the app declared in APK.
permissions Print the permissions from the APK.
resources Print the resource table from the APK.
configurations Print the configurations in the APK.
xmltree Print the compiled xmls in the given assets.
xmlstrings Print the strings of the given compiled xml assets.

Package the android resources. It will read assets and resources that are
supplied with the -M -A -S or raw-files-dir arguments. The -J -P -F and -R
options control which files are output.

aapt r[emove] [-v] file.{zip,jar,apk} file1 [file2 ...]
Delete specified files from Zip-compatible archive.

aapt a[dd] [-v] file.{zip,jar,apk} file1 [file2 ...]
Add specified files to Zip-compatible archive.

aapt v[ersion]
Print program version.

Modifiers:
-a print Android-specific data (resources, manifest) when listing
-c specify which configurations to include. The default is all
configurations. The value of the parameter should be a comma
separated list of configuration values. Locales should be specified
as either a language or language-region pair. Some examples:
en
port,en
port,land,en_US
If you put the special locale, zz_ZZ on the list, it will perform
pseudolocalization on the default locale, modifying all of the
strings so you can look for strings that missed the
internationalization process. For example:
port,land,zz_ZZ
-d one or more device assets to include, separated by commas
-f force overwrite of existing files
-g specify a pixel tolerance to force images to grayscale, default 0
-j specify a jar or zip file containing classes to include
-k junk path of file(s) added
-m make package directories under location specified by -J
-u update existing packages (add new, replace older, remove deleted files)
-v verbose output
-x create extending (non-application) resource IDs
-z require localization of resource attributes marked with
localization="suggested"
-A additional directory in which to find raw asset files
-G A file to output proguard options into.
-F specify the apk file to output
-I add an existing package to base include set
-J specify where to output R.java resource constant definitions
-M specify full path to AndroidManifest.xml to include in zip
-P specify where to output public resource definitions
-S directory in which to find resources. Multiple directories will be scanned
and the first match found (left to right) will take precedence.
-0 specifies an additional extension for which such files will not
be stored compressed in the .apk. An empty string means to not
compress any files at all.
--debug-mode
inserts android:debuggable="true" in to the application node of the
manifest, making the application debuggable even on production devices.
--min-sdk-version
inserts android:minSdkVersion in to manifest. If the version is 7 or
higher, the default encoding for resources will be in UTF-8.
--target-sdk-version
inserts android:targetSdkVersion in to manifest.
--max-res-version
ignores versioned resource directories above the given value.
--values
when used with "dump resources" also includes resource values.
--version-code
inserts android:versionCode in to manifest.
--version-name
inserts android:versionName in to manifest.
--custom-package
generates R.java into a different package.
--auto-add-overlay
Automatically add resources that are only in overlays.
--rename-manifest-package
Rewrite the manifest so that its package name is the package name
given here. Relative class names (for example .Foo) will be
changed to absolute names with the old package so that the code
does not need to change.
--rename-instrumentation-target-package
Rewrite the manifest so that all of its instrumentation
components target the given package. Useful when used in
conjunction with --rename-manifest-package to fix tests against
a package that has been renamed.
--product
Specifies which variant to choose for strings that have
product variants
--utf16
changes default encoding for resources to UTF-16. Only useful when API
level is set to 7 or higher where the default encoding is UTF-8.
--non-constant-id
Make the resources ID non constant. This is required to make an R java class
that does not contain the final value but is used to make reusable compiled
libraries that need to access resources.

Yesterday everything was fine, but today after the update it doesn't work anymore.





is UIScrollView or a UIWebView the better solution for this?

I am spec'ing out an iOS app and there is a piece that is a run-on section that will need to scroll. I was thinking of doing it as a UIScrollView (have never used one but seems logical) but it sounds like the contentSize always needs to be calculated. This could be extremely variable in this case (UGC images etc...). Is this correct? Or is there a legitimate workaround? If not, would a UIWebView be the better solution?



The app functionality would be like a FB feed or Instagram. Is it known what they use (FB looks like UIWebView to me).



thx
