T410 USB not working - SOLVED

2011-05-24T12:09:00.000-07:00

I tried posting this to the Lenovo Community thread but after I registered, everything was in German and it wouldn't let me post.

But, for those struggling with the same issue, here's how I solved it.

1. Right-click on "My Computer"
2. Select Manage
3. Expand the "Universal Serial Bus controllers"
4. Right-click on the first "USB Root Hub"
5. Select Properties
6. Select the "Power Management" tab
7. Uncheck "Allow the computer to turn off this device to save power."
8. Click OK
9. Repeat steps 4-8 for the other "USB Root Hub"
10. Right-click each USB Root Hub and uninstall each one
11. Right-click on the "Universal Serial Bus controllers"
12. Select "Scan for hardware changes"
13. Let all the stuff reconnect (USB hubs, camera, fingerprint, AND MOUSE! :)
14. Done!

Bloggerdise.com

2011-02-08T05:19:00.000-08:00

So a few of us are starting a free new service website called Bloggerdise.com. It helps businesses and bloggers connect by allowing bloggers search through unique offers, samples, etc and work out a deal directly with businesses to review their products or services.

Does it work? At least a few folks think so in the forum.

It's still a work in progress, but the site is definitely gaining momentum.

Dabbling with FileExists and SSIS packages

2009-10-13T11:36:00.001-07:00

So I've been trolling around through the www trying to find a quick (and dirty way) to determine if a file exists before executing some SQL. I found a few articles through the wonders of googling and there are a lot of ways (SSIS:: Test for Data Files Existence, Determining if a File Exists in SSIS Using Wildcards, Check if File Exists, Does File Exist Check in SSIS) to skin this cat, but I felt there had to be a simpler way.

Basically, I ended up using the "Set Attributes" operation in a File System Task Editor and an existing SourceConnection.

There are a few assumptions here...
1. The source connection file should exist when first creating the connection.
2. Setting all of the attributes (hidden, read-only, archive, system) to False is ok.
3. You don't mind hacks.

So here are the steps you can take to check if one or more file exists before executing your SQL:
1. Set up a new file connection pointing to the file to be loaded.
2. Create a File System Task using the "Set Attributes" operation.
3. Add your precedence constraint/connectors.

Test the steps by executing the task once (should turn green). Then rename the source file and executing the step again (should turn red).

I haven't tested this in a production environment but figured I'd write it down and see if it works for others.

Good luck and happy coding!

Beginning to hate IX Web Hosting

2008-12-26T14:01:00.000-08:00

Today, I discovered that a couple of my sites were no longer responding correctly--they're hosted with IX Web hosting.

something is wrong with some of the sites that are hosted under my domain... parkapps.com, jin-park.com, mtcarmelchurch.org

you: they are all requiring a password... nothing has changed on the server for a few days now

you: 401 Error - Unauthorized HTTP Error 401.3 - Unauthorized: Access is denied due to an ACL set on the requested resource. You are recieving this message because the resource you have requested is unauthorized to your connection. You must first be authenticated in order to access the requested resource. No further information on authenticating for use of that resource is available.

Oleg Kovalenko : Please hold on, let me check

you: also, when i go to use the file manager, i get the following error...

you: ERROR: Unable to change dir "/" Check directory permissions

The site boasts "unlimited" disk storage, and yet, I found an arm-twisting "support" message saying that I've violated the "fair-use" resource assignment. Very odd indeed...

We are notifying you that your account has been found to violate our “Fair-Use” Resource Assignment portion of our Terms of Service, due to the amount of disk usage that is being taken.

We ask that you either reduce disk usage (now you use 51GB) or look for dedicated hosting for this site.

We have a shared hosting environment that we must maintain at a certain level of performance. This performance is monitored and balanced by us, however there are times when accounts can cause the server’s load to increase degrading the performance for all other customers on this server.

To protect your account from further action you must agree to our request for compliance. Please respond to this message stating your intent to do so. You may either log into your control panel with us, and access this ticket via the 24/7 help desk, or provide this ticket number to our Live Chat or phone representatives. Failure to respond to this message within 72 hours will result in the suspension of the affected domain with us until such a time as this matter is resolved.

focusing in on a field that's empty with javascript

2008-07-23T08:04:00.000-07:00

There seems to be a weirdness when leaving a field that's empty and trying to get the browser to focus back on it. It does it momentarily, but then decides to go back. This script will force the cursor back and focus on the offending field after .1 seconds of leaving it.


<script>
var myInput = '';
function checkMe(obj) {
if(obj.value == '') {
myInput = obj;
myInput.style.background = 'yellow';
myInput.setAttribute('title','This is a required field and blah blah blah');
window.setTimeout('myInput.focus()',100);
}
}
</script>
<input id="foo1" name="foo1" value="init" onchange="checkMe(this);">

<input id="foo2" name="foo2" value="check" onchange="checkMe(this);">

<input id="foo3" name="foo3" value="last" onchange="checkMe(this);">

Values Clarification

2008-04-04T19:00:00.000-07:00

I'd like to clarify my values for my blog readers... me

According to the office of career & professional development (ucsf) values clarification worksheet, the following are my work-related values that I rank the highest:

status
monetary reward
creative
balance
influence
recognition

my wife's are:

work/life balance
moral fulfillment
location
excitement
to help society
make decisions
knowledge

What does this all mean? Well I guess that's to be determined since these are really future career goals. :)

just a few random thoughts about working

2008-01-30T12:36:00.000-08:00

work hard and appreciate those who work hard around you
keep your crown at home next to your throne

Work in store - days 4 & 5

2008-01-14T06:08:00.000-08:00

Thursday and Friday I worked in the following departments:

GM (valentines, stocking shelves)
Floral
Cheese shop
Wine

Somehow, the network team blocked my internet access from the store as well....

Associates at the store really love what they do. They're the best of the best and really work hard at making the store look great.

It could have been 4 days instead of 5. by the last day, i was dog tired! :)

work in store - day 3

2008-01-09T14:51:00.000-08:00

today i went back to the store and parked in the rear lot--believe it or not, it's a big deal where you park. in the morning, i stocked shelves because the store was so successful over the weekend in sales (that's a good thing) it rippled into the backroom which is too small for the size of the store and caused a lot of gaps. it's also a lot of work to make sure that the shelves are full and stocked with the correct product.

in the afternoon, i followed one of the co-managers (josh) to do freshness checks, store walk, and make sure that everything was in order. We even put up fresh balloons around the store to highlight the arrival of valentines day.

josh highlighted the k** r******** posters around the backroom, tying it in with shelf stocking, and the general condition of the back during a change in holiday and in between store audits. it's really quite amazing all that goes on in order to keep the store at such a pristine level... product must be displayed properly, enough variety is an issue, and most of all, keeping customers happy is so hard. even harder is weeding out those that are trying to scam or steal--yikes.

how many times did i get asked where something was? three. how many times did i know? zero.

work-in-store program

2008-01-08T16:33:00.001-08:00

so what have i learned after two days working at my local store?

it is non-stop working with customers, shelves, floors and products--associates feed off the energy
they sell a local brand of ice cream from aglameses bros
managers are held accountable for every single corporate initiative out there
meetings can be long and detailed
packing meat is cold bloody work
scanning with the CAO gun is weird and non-intuitive
the web tools that we make stores use are also weird and non-intuitive
parking is an issue for associates
the day crew is pretty different from the evening crew
bagging can be fun but also can make you feel like a lonely puppy when you greet customers excitedly and they give no acknowledgment
it's really tough work doing what stores do

good listening

2008-01-06T05:28:00.001-08:00

a friend of mine sent this to me a few days back. it's a sermon about the parable of an owner of a field and the number of talents he gives each of them. it's always been assumed that if you were given the 10 talents and made 10 more, you were the hero and if you were given one talent and hid it in the ground, you were the loser. what if it was the other way around?

organic bananas

2008-01-06T05:23:00.000-08:00

organic bananas are really good. the peels are thicker and keep the inside fresher for a longer time. Plus, when they do start to ripen, the outside might look a little beat up, but it's really not indicative of the condition on the inside. they also go great with honey almond flax kashi cereal. mmm breakfast

Final Day

Working with Data in Flex
Tom Lane

What's different about data in Flex?
the role client and server played in architecture
server is doing the work of plugging data into UI (server-side)
ajax server sends abstract data to the client (client-side/server-side hybrid model)
google suggest - selectively employs AJAX to spice up spots
roby partials - async update of a chunk of server generated HTML
Flex is 100% UI on the client
client requests and server sends abstract data

Flex Data Fundamentals
Three data "paradigm" objects:
- weakly typed
- most basic
- in actionscript
var myobject:ObjectProxy = new ObjectProxy();
myobject.title = "Pocket Symphony";
- in mxml
mx:Model (bonus: you can defined init data with xml)

<>Pocket Symphony<>

mxml has only one root node (album)

pros - you can do whatever you wan, add new properites, don't have to code anything else
cons - your misspellings kill you

- XML (still weakly typed)
in actionscript
var myxml:XML = ; (weird)
you get E4X support "dot" syntax
mytree..treeitem.@label - returns all the labels of tree item nodes at any level in a tree
if you use it, it's harder to migrate to strong typing
- strongly typed
use an actionscript class to formally define the data
{Bindable]
public class Album {
public var title:string;
public var artist:string;
public var tracks:ArrayCollection;
}
To instantiate in ActionScript
var album:Album = new Album();
album.title = 'Pocket Symphony';
In MXML:

Pocket Symphony

flex builder catches problems - compile time validation
- code hinting
- get/set methods

Making data [Bindable] databinding
- every property in this class is now bindable

arrays class is too simple to suppor tdatabinding, but ArrayCollection does support it
ArrayCollection is generically typed in that everything is an Object when it comes out
var item = ac.getItemAt(0);
var item:* = ac.getItemAt(0); // confirm i really want to make this variable typeless
var item:Album = ac.getItemAt(0) as Album; // not 100% safe b/c no guarantee, but it's pretty safe

Flex Services
ways of talking between client and server
RPC servces (http, web, remoteobject)
data management service CRUD, pushing updates, breaking up large results into chunks
FlickrAPI HTTPService cilent proxy
webservice - overhauled
- wsdl (SOAP encoded)
- Data > Import Web Service
remoteObject
- aka flash remoting
- more efficient binary encoding
JSON = crazy alternative to XML serialization
security hole (never eval() JSON in the first place)

RPC service stumbling blocks
make sure to handle faults
implement fault="handleFault(event)" to display errors
function handleResult(event:resultEvent) {...

data management service
- sync collections bwetween colient & server
- resolve confilcts
- push updateds to clients
- handle large results - page results and lazily load related data

dataservice client code

- fill -
- commit
- outside of collections

automagic via servier cahcing of the fill query
to scale turn off
[Managed] on the client classes plus some service config to define relationships

server-side assembler
fill, get, count, sync
or just extend AbstractAssembeler

Ideal for keeping clients sycnhed
trickey when changes can come externally
Data Msg'ng
Provides a real-time consumer producer model
Remote objects
CFC's

Process

Group development: challenging synchronization
1 week of rapid development w/ (in)experienced flex dev's
new software dev paradigm for compiled code
new challenge: server push

tech solution summary

consumer/producer messaging
coldfusion server push
one-quarter second
cf gateways
cell renderers

cf8/lcds 2.5
flex builder 2.01
sql server 2005

They keep 5 years of data

Conclusion

Flex helped to achieve long-term goals - external adoption
Flex LCDS is a viable tool fro real0time financial apps
freedom from client
keeping relevant tech in front of new gen of students

Leveraging ColdFusion Components

blessing and curse

the problem with rapid development is that it's too easy to write spaghetti code
resist the urge to File.. New,
spaghetti code = bad
cfinclude - good for reusing static html but that output can't be customized

cf_customtag

for customized content

user defined functions

can easily return values but
code must be manually included
udfs are just collections of methods, data is not encapsulated
can't be used outside of a .cfm page

CFCs

encourage better code org
easier to call/invoke
more functional than UDFs
stores instance data as well as encapsulate functions
reusable from any app that can use web services or flash remoting

basic rules

start w/ a set of udf's in component tag
use .cfc file extension
store .cfc files in the web root (if cfc's will be called as web services)

anatomy of a cfc

benefits
the cfc file doesn't have to be included

Demo 1

demo a simple CRUD app
pick a page and move its brains (data access code) into CFC

Using CFC's

building blocks for page based apps
vs CreateObject
