How to use the Feathers NumericStepper
component
The NumericStepper
component displays a numeric value between a minimum and maximum. The value may be changed by pressing the increment or decrement buttons. If editing is enabled (typically not enabled on mobile), the value may be changed by typing a value into a text input.
The Basics
First, let's create a NumericStepper
control, set up its range of values, and add it to the display list.
var stepper:NumericStepper = new NumericStepper();
stepper.minimum = 0;
stepper.maximum = 100;
stepper.value = 50;
this.addChild( stepper );
The value
property indicates the current value of the stepper, while the minimum
and maximum
properties establish a range of possible values. We can further control the stepper's behavior with the step
property:
stepper.step = 1;
The step
property controls how the numeric stepper's value is rounded as the user interacts with it. If we set the stepper's step
to 1
, as we do above, the stepper will increment on whole numbers only, and it cannot have a value like 4.5
, for instance.
Add a listener to the Event.CHANGE
event to know when the value
property changes:
stepper.addEventListener( Event.CHANGE, stepper_changeHandler );
The listener might look something like this:
function stepper_changeHandler( event:Event ):void
{
var stepper:NumericStepper = NumericStepper( event.currentTarget );
trace( "stepper.value changed:", stepper.value);
}
Skinning a NumericStepper
The skins for a NumericStepper
control are divided into three parts. There are the increment and decrement buttons and the text input. There are a few different layout modes that control where the buttons are placed relative to the text input. For full details about what skin and style properties are available, see the NumericStepper
API reference. We'll look at a few of the most common properties below.
Layout
The numeric stepper's layout can be customized to place the buttons in different locations. In the example below, we place the buttons on the right side of the text input, stacked vertically, like you see with many desktop numeric steppers using StepperButtonLayoutMode.RIGHT_SIDE_VERTICAL
:
stepper.buttonLayoutMode = StepperButtonLayoutMode.RIGHT_SIDE_VERTICAL;
There are two additional options for buttonLayoutMode
. You can use StepperButtonLayoutMode.SPLIT_HORIZONTAL
to place the decrement button on the left side of the text input and the increment button button on the right side. Similarly, you can use StepperButtonLayoutMode.SPLIT_VERTICAL
to place the increment button on top of the text input and the decrement button on the bottom.
A gap may be placed between the text input and any button positioned next to it:
stepper.textInputGap = 10;
Simply set the textInputGap
property to adjust this spacing.
When the buttons are both placed on the same side of the text input, you can include a gap between them too:
stepper.buttonLayoutMode = StepperButtonLayoutMode.RIGHT_SIDE_VERTICAL;
stepper.buttonGap = 3;
If the buttons are on different sides of the text input, the buttonGap
property is ignored.
Skinning the Decrement Button
This section only explains how to access the decrement button sub-component. Please read How to use the Feathers Button
component for full details about the skinning properties that are available on Button
components.
With a Theme
If you're creating a theme, you can target the NumericStepper.DEFAULT_CHILD_STYLE_NAME_DECREMENT_BUTTON
style name.
getStyleProviderForClass( Button )
.setFunctionForStyleName( NumericStepper.DEFAULT_CHILD_STYLE_NAME_DECREMENT_BUTTON, setNumericStepperDecrementButtonStyles );
The styling function might look like this:
private function setNumericStepperDecrementButtonStyles( button:Button ):void
{
var skin:ImageSkin = new ImageSkin( upTexture );
skin.setTextureForState( ButtonState.DOWN, downTexture );
button.defaultSkin = skin;
button.defaultIcon = newImage( decrementIconTexture );
}
You can override the default style name to use a different one in your theme, if you prefer:
stepper.customDecrementButtonStyleName = "custom-decrement-button";
You can set the function for the customDecrementButtonStyleName
like this:
getStyleProviderForClass( Button )
.setFunctionForStyleName( "custom-decrement-button", setNumericStepperCustomDecrementButtonStyles );
Without a Theme
If you are not using a theme, you can use decrementButtonFactory
to provide skins for the numeric stepper's decrement button:
stepper.decrementButtonFactory = function():Button
{
var button:Button = new Button();
//skin the decrement button here, if not using a theme
var skin:ImageSkin = new ImageSkin( upTexture );
skin.setTextureForState( ButtonState.DOWN, downTexture );
button.defaultSkin = skin;
button.defaultIcon = newImage( decrementIconTexture );
return button;
}
Skinning the Increment Button
This section only explains how to access the increment button sub-component. Please read How to use the Feathers Button
component for full details about the skinning properties that are available on Button
components.
The numeric stepper's increment button may be skinned similarly to the decrement button. The style name to use with themes is NumericStepper.DEFAULT_CHILD_STYLE_NAME_INCREMENT_BUTTON
or you can customize the style name with customIncrementButtonStyleName
. If you aren't using a theme, then you can use incrementButtonFactory
.
Skinning the Text Input
This section only explains how to access the text input sub-component. Please read How to use the Feathers TextInput
component for full details about the skinning properties that are available on TextInput
components.
With a Theme
If you're creating a theme, you can target the NumericStepper.DEFAULT_CHILD_STYLE_NAME_TEXT_INPUT
style name.
getStyleProviderForClass( TextInput )
.setFunctionForStyleName( NumericStepper.DEFAULT_CHILD_STYLE_NAME_TEXT_INPUT, setNumericStepperTextInputStyles );
The styling function might look like this:
private function setNumericStepperTextInputStyles( input:TextInput ):void
{
input.backgroundSkin = new Image( backgroundTexture );
input.padding = 20;
input.isEditable = false;
}
You can override the default style name to use a different one in your theme, if you prefer:
stepper.customTextInputStyleName = "custom-text-input";
You can set the function for the customTextInputStyleName
like this:
getStyleProviderForClass( TextInput )
.setFunctionForStyleName( "custom-text-input", setNumericStepperCustomTextInputStyles );
Without a Theme
If you are not using a theme, you can use textInputFactory
provide skins for the numeric stepper's text input:
stepper.textInputFactory = function():TextInput
{
var input:TextInput = new TextInput();
//skin the text input here, if not using a theme
input.backgroundSkin = new Image( backgroundTexture );
input.padding = 20;
input.isEditable = false;
return input;
}


Hi, could you use transparent background in charts? Some ppl (incl. me) are using stylized battlelog (into dark colors) and transparent chart would fit much better. For charts, you can add this, into the link - chf=bg,s,FFFFFF00&
You could also edit accuracy plot and the dmg value box img and fit it with transparent bacground.
Thanks

Hey,
Transparent charts -> No problem - Come in next update.
Accuracy Plot - It will never be changed, it must be a white background to get it clearly visible with the colors inside. And i not want to re-create every plot for white and dark backgrounds - Sorry.
Dmg Value Box - Same as Accuracy, but i make in the next update the complete box with a white background to remove the edges from the graph.

Hi,
plot accuracy - understand, that would be a lot of work.
Damage torso - i sent you something on your mail, look at it ;)

About
NostraDavid; the author
I’m someone who’s sick of the state of the web and you know what they say:
Improve the world, start with yourself - Bond Zonder Naam
This is why I started with the basics: HTML, CSS and JS. Anything else is deemed bloat
Thaumatorium
The name
It’s based on the word thaumaturge, meaning miracle worker, thus Thaumatorium is where miracles are performed.
The reason - the why
I wanted a place where I could post my articles, but I found my free Wordpress site too slow, too bloated, too messy, so I started to search for a way to still create and host articles, without needing bloat like Wordpress.
I started with thinking about using something like Angular and React. They were the hot new thing in town, so why not try that?
After finding Elm, a Haskell-like language that compiles to JS I though to use that as it promised small and (more importantly) fast websites.
After learning the creator wasn’t the… most cooperating of persons I decided to move on before even clashing with him.
I quickly found the Blazor beta, which seemed promising, especially in the PWA department. Downsides: the output is rather huge (4MB+ in size) and the code is based on the Mono lib, not the fastest of libs.
So I ended up thinking: What’s left after removing all and anything bloat? HTML. CSS. JS… So why not create my site in that? So I set out to create a PWA - a single HTML page that contains the whole site.
The site quickly grew too big for this, so I changed it up by splitting the site in separate HTML pages, but index.html contained the generic header/footer HTML, while the other HTML files contained the articles.
In doing so - splitting the site, but mostly handling things like a PWA - I broke the back/forward buttons and browser history…
In the end I decided in writing just separate HTML pages, which means I have a bunch of duplicate HTML, but I’m OK with that, as I know enough REGEX to edit all HTML headers in one fell swoop!

There’s a lot more that I’m going to forbid, but I think that’s one of the big ones - one you don’t see on other sites, unlike the stereotypical “no racism, hate, etc” virtue signalling bullshit.
Yes, I also hate Virtue Signalling month of June. LGBT all of a sudden matters to giant corporations.  They’re basically lying to their western customers, acting as if they’re doing good, while only changing the icon in the place that already legally and socially accept LGBT humans.
Ooh!

Anyway, I’m thinking about banning Americans from my site too. I’m not going to accept people who are retarded. People with mental disabilities are still welcome, ofcourse.

PS: The definition of the word “Racism” is NOT “power + prejudice”.
PPS: Right-wingers may now start to get the idea I’m /their guy/. I’m not.  Please.
The cure
Great minds discuss ideas, average minds discuss events, small minds discuss people. – Eleanor Roosevelt
We (the internet at large) are too busy with discussing people, not even events. I want to see the internet move back to discussing ideas. That was more the case on Reddit back in the days - Reddit on 2008-12-29 was much more about ideas, not events or people.
The normies have invaded the internet. That’s not necessarily bad, but what is is that they came in such numbers they did not need to adapt to our netizenship and changed our internet culture. For the worse, mind you. I hope to one day have enough influence to change that, for the betterment of humanity.


Today was Eid al Fitr, the end of the month of Ramadan. For a while, it became like the part of Halloween for kids. I've got a few pictures of that, and me and some of the other PCTs. In some ways, things are beginning to get a little tough, but it's still great to be here.
This is actually kinda hard!
Well, here goes… I'm going for the picture upload. I've been getting better data connections lately, so I might be able to get this uploaded in a reasonable amount of time…
Things are still going well, but it's definitely getting harder. The initial excitement has worn off, and a lot of us are starting to feel like it's a bit of a grind. I've got it easy, since I speak French well; the folks who are just learning French have the constant stress of being emerged in a foreign language. It's bad enough for me, with the double frustration of my good-but-imperfect French, and the variable level of French proficiency among the Burkinabè.
We're still in a bit of an artificial environment, even though we're in a village, and living with families. The Peace Corps is taking care of us in ways that I think are meant to be hidden, like the fact that all of the area restaurants are being subsidized to wash their vegetables in chlorinated water before serving them to us. It makes sense, since we can't cook for ourselves, and we have to eat in restaurants for lunch. The Peace Corps is also making things artifically hard for us, like, for example, instructing host families that they are forbidden from speaking English to us even if they speak it perfectly well.
The only reason I know this is that my French is good enough to get chatty with folks like restaurant owners, and I guess the Peace Corps didn't tell them to keep it a secret :-)
It's kind of hard to know what to write, because a lot of what's going on would sound munane. A lot of Peace Corps blogs and videos talk about pooping in a hole, but a pit latrine really isn't that big a deal, for example. The things that are grinding me down a bit are the lack of communication, since they don't open up the Peace Corps training wifi to us (maybe because we'd overload it), exacerbated by a cell data network being overloaded by 70 volunteer smartphones. Another mundane-but-frustrating fact: The power goes out all the time. So does the water, specifically, when the power to the pumping station goes out. So there's that. Also, it turns out that when you add 14 drops of chlorine every time you put 7 liters of water in your top bucket, the water comes out tasting of chlorine. Who knew? Oh, and the insecticide in my mosquito net makes me sneeze. But it kills mosquitos, so I'll take it.
It's probably a good thing I don't have a brother, because I would kill my brother for a plate of brussels sprouts and a café gourmand (a French espresso with four tiny desserts) right about now. Pretty much every meal is a starch and meat, maybe with a couple of vegetables. Most meals are just the main course, though with maybe a mango or a couple of banannas every couple of days. Not many fruits or vegetables is what I'm saying. I think this part will get better when I'm at site, since I'll be in more control of my own diet.
My fellow volunteers continue to be awesome.
Happy Eid!
Today everybody celebrated Eid al Fitr, which I guess means it started last night at sundown. That's the end of Ramadan, so muslims (like my host family) won't be fasting during the day anymore. They celebrate Eid by going around visiting eachother, mostly, which is pretty wonderful. I saw the father of my host family's mother, father and grandfather, and met scads of his brothers and sisters, all within a couple of blocks. You end up eating lots of meals – I got up to at three lunchs and two dinners by the close of festivities. Happily, it's OK to just take a tiny bit of food.
The other big thing that happens is that kids go house to house asking for candy. We were warned, so I had a little bag of hard candies to give out. All of the kids wear their best clothes for their Eid trick-or-treating; they're quite beautiful and charming.

Trump says looking at whether Apple should be exempt from China tariffs
by ReutersAUSTIN, Texas (Reuters) - U.S. President Donald Trump said on Wednesday he was considering whether to exempt Apple Inc (O:AAPL) from tariffs on Chinese imports.
"We're looking at that," Trump said in answer to a reporter's question about the tariffs. He spoke after touring a plant in Austin with Apple Chief Executive Tim Cook that assembles Apple computers.


Delta propagation reduces the amount of data you send over the network. You do this by only sending the change, or delta, information about an object, instead of sending the entire changed object. If you do not use cloning when applying the deltas, you can also expect to generate less garbage in your receiving JVMs.
In most distributed data management systems, the data stored in the system tends to be created once and then updated frequently. These updates are sent to other members for event propagation, redundancy management, and cache consistency in general. Tracking only the changes in an updated object and sending only the deltas mean lower network transmission costs and lower object serialization/deserialization costs. Performance improvements can be significant, especially when changes to an object are small relative to its overall size.
Geode propagates object deltas using methods that you program.  If any of your classes are plain old Java objects, you need to wrap them for this implementation.
This figure shows delta propagation for a change to an entry with key, k, and value object, v.
-
get
operation. Theget
works as usual: the cache returns the full entry object from the local cache or, if it isn’t available there, from a remote cache or from a loader. - update methods. You need to add code to the object’s update methods so that they save delta information for object updates, in addition to the work they were already doing.
-
put
operation. Theput
works as usual in the local cache, using the full value, then callshasDelta
to see if there are deltas andtoDelta
to serialize the information. Distribution is the same as for full values, according to member and region configuration. - receipt of delta at remote member.
fromDelta
extracts the delta information that was serialized bytoDelta
and applies it to the object in the local cache. The delta is applied directly to the existing value or to a clone, depending on how you configure it for the region. - additional distributions. As with full distributions, receiving members forward the delta according to their configurations and connections to other members. For example, if VM1 is a client and VM2 is a server, VM2 forwards the delta to its peers and its other clients as needed. Receiving members do not recreate the delta;
toDelta
is only called in the originating member.
General Characteristics of Delta Propagation
To use the delta propagation feature, all updates on a key in a region must have value types that implement the Delta
interface. You cannot mix object types for an entry key where some of the types implement delta and some do not. This is because, when a type implementing the delta interface is received for an update, the existing value for the key is cast to a Delta
type to apply the received delta. If the existing type does not also implement the Delta
interface, the operation throws a ClassCastException
.
Note: Only the object itself being placed in the cache can implement the Delta
interface and propagate changes. Any sub-objects of the cache object do not propagate their changes.
Sometimes fromDelta
cannot be invoked because there is no object to apply the delta to in the receiving cache. When this happens, the system automatically does a full value distribution to the receiver. These are the possible scenarios:
1. If the system can determine beforehand that the receiver does not have a local copy, it sends the initial message with the full value. This is possible when regions are configured with no local data storage, such as with the region shortcut settings PARTITION_PROXY
and REPLICATE_PROXY
. These configurations are used to accomplish things like provide data update information to listeners and to pass updates forward to clients.
2. In less obvious cases, such as when an entry has been locally deleted, first the delta is sent, then the receiver requests a full value and that is sent. Whenever the full value is received, any further distributions to the receiver’s peers or clients uses the full value.
Geode also does not propagate deltas for:
- Transactional commit
- The
putAll
operation - JVMs running Geode versions that do not support delta propagation (6.0 and earlier)
Supported Topologies and Limitations
The following topologies support delta propagation (with some limitations):
- Peer-to-peer. Geode system members distribute and receive entry changes using delta propagation, with these requirements and caveats:
- Regions must be partitioned or have their scope set to
distributed-ack
orglobal
. The region shortcut settings for distributed regions usedistributed-ack
scope
. Delta propagation does not work for regions withdistributed-no-ack
scope
because the receiver could not recover if an exception occurred while applying the delta. - For partitioned regions, if a receiving peer does not hold the primary or a secondary copy of the entry, but still requires a value, the system automatically sends the full value.
- To receive deltas, a region must be non-empty. The system automatically sends the full value to empty regions. Empty regions can send deltas.
- Regions must be partitioned or have their scope set to
- Client/server. Geode clients can always send deltas to the servers, and servers can usually sent deltas to clients. These configurations require the servers to send full values to the clients, instead of deltas:
- When the client’s
gemfire.properties
settingconflate-events
is set to true, the servers send full values for all regions. - When the server region attribute
enable-subscription-conflation
is set to true and the clientgemfire.properties
settingconflate-events
is set toserver
, the servers send full values for the region. - When the client region is configured with the
PROXY
client region shortcut setting (empty client region), servers send full values.
- When the client’s
- Multi-site (WAN). Gateway senders do not send Deltas. The full value is always sent.

Bitcoin Price: Bullish Macro Trend Intact — But $6,800 Will Be Key
by Michaël van de PoppeAs the price of Bitcoin (BTC) was retracing from the massive rally four weeks ago, no clear indications were seen on the charts of a potential reversal. Thus, the price started to accelerate downwards to the next support areas, causing the price to drop $1,000 within one day.
Crypto market data. Source: Coin360
However, is the bear market imminent, or is it still applicable to state that this is a bull market retracement? Let’s analyze the charts.
Bitcoin lost crucial $8,200 support level
As discussed in the previous article, the bearish scenario provided opportunities to potentially short the market.
BTC USD 6-hour chart. Source: TradingView
Through this, the falling wedge structure wasn’t confirmed, and the price fell below the support zone (yellow area). After that, a small rejection was seen before the price started to fall through to the next critical support zone. This zone is marked in the green area and can also be defined through the trendline (blue line).
However, daily timeframes show that the price has retraced to the golden ratio (0.618-0.65 Fibonacci level) of the whole upwards move during the first half of 2019 ($3,000 to $14,000).
BTC USD daily chart. Source: TradingView
In this chart, it can be seen that the price couldn’t clear back up above $9,300, which caused the price to retrace downwards. By losing the $8,200 support area, the price started to accelerate down towards the next critical support zone around the 0.618-0.65 Fibonacci level.
Aside from that, the price is still stuck inside a big downwards trending channel, making lower lows and lower highs, which can be considered bearish.
Golden ratio retracements occur frequently
However, golden ratio support levels are significantly healthy in general and have shown up frequently in the Bitcoin market.
For example, the first parabolic move in 2016 retraced down towards this crucial Fibonacci level, as seen in the following chart.
BTC USD 2016 Chart. Source: TradingView
Another example is seen during the 2017 bull market when the price retraced towards the 0.618-0.65 Fibonacci level on news of a potential Chinese “ban” dropping from $5,000 to $3,000.
BTC USD 2017 Chart. Source: TradingView
More examples are found in the charts (also from prior market cycles). So can it be stated that this is a bottom call?
No.
But this does show the significance of this key level. Combined with the fact that the overall sentiment is back to “extreme fear,” a potential “buy the dip” scenario could present itself in these zones. Many investors have been dying to buy at these levels earlier this year.
Macrotrend still unbroken
BTC USD Macro view. Source: TradingView
This chart shows the macrotrend since the beginning of 2015. The trend marked the bottom of the bear market in December 2018, as the price jumped up from there and started to rally upwards to the recent high of $14,000 in June 2019.
Interestingly enough, the move from $3,000 to $14,000 also bounced back from the similar Fibonacci level, once again showing the significance of the golden ratio.
Bitcoin has to maintain the green zone (which is the order block between $6,000 and $6,800) as support on the weekly timeframe and needs to keep the blue trendline as support.
If this holds, the price looks ready to continue its overall upward trajectory and targets of $14,000-20,000 would remain on the table for next year.
Bullish scenario
However, what does BTC/USD need to do on shorter time frames to make the chart look more attractive?
BTC USD 12-hour chart. Source: TradingView
The first step before any major U-turn would be clearing the $7,350-7,400 area. If Bitcoin can break to the upside here, continuation is likely towards $7,800, and a temporary bottom would be achieved.
In that regard, continuation in this channel is likely, which suggests that BTC will have a few more months of sideways action in this area (between $6,900 and $8,200). The reasoning is simple: the other trendline of the channel is quite far away from here, implying that it would take until January before that zone is reached.
BTC USD 1-hour chart. Source: TradingView
On the smaller time frames, only a bullish divergence on the 1-hour chart is found for any reversal signals. Aside from that, a move of $500 already confirmed this bullish divergence.
However, the price couldn’t break up above $7,400, which is needed for any short term reversal, as discussed above.
On the smaller time frames, a higher low needs to form to retest the $7,400 again. If this level is broken, targets for bullish movements are found at $7,800 and $8,200.
Bearish scenario
BTC USD bearish scenario. Source: TradingView
Nevertheless, the price is still trending downwards in a substantial manner, so the recent price action is classified as bearish.
If the price is not able to break through $7,400, further downwards pressure is expected. In that regard, targets of $6,600-6,800 are back on the table for a potential long entry, in which the lows are swept and liquidity is taken back again.
In this potential downwards move, another retest of the trendline would occur, and potential bullish divergences can be built on higher time frames as well.
Conclusion
Since the overall sentiment is bearish — and people are fearful of buying back in — it wouldn’t be surprising to see a short-term reversal in the market. In that regard, taking a long position and aiming to close it in the $8,200 area would make sense as this is the next significant level of resistance.
But if the $7,400 isn’t breached in the next few days, more downwards pressure can be expected to the dismay of the bulls.

by None at 2020-04-09 15:41:15.@windcowles for employment affiliation will you want all available or just the most recent? If all, we'll need to combine them into one column to keep the associations between organization, department, and title. For example:
Option A:
Name, orcid, employment affiliation
Anna, xxx, Princeton University / DRDS / Developer; CHF / Library / Developer
Option B:
Name, orcid, employment organization, department, title
Anna, xxx, Princeton University, DRDS, Developer
I guess there's also an Option C which is like Option B but each individual has multiple row entries (one for each employment affiliation)
@hackmastera - we want current Princeton employment and so I think that most recent is probably fine.

The original request and the request we're making now may not fully align.

by None at 2020-04-09 13:00:33.@kevinreiss, @mzelesky and I looked into this: looking in the catalog https://catalog.princeton.edu/?f%5Baccess_facet%5D%5B%5D=In+the+Library&q=id%3Adsp*&search_field=all_fields all of the items with an id dsp (dspace) are in the Mudd Library and locationcode is "mudd" https://catalog.princeton.edu/catalog/dsp019c67wp402/raw. As a first answer I would say that checking location mud is enough to decide for the request.
But there is a dspace:true or dspace:false in the holdings1display key "thesis" which seems to change the availability.
Based on this example https://catalog.princeton.edu/catalog/dsp01k0698b34p we should check the key thesis and the dspace value and if it is false (which means that it's embargoed), then we should not display the 'Reading room Request' button. Is this correct? This is the holdings_1display field: "holdings_1display":"{\"thesis\":{\"location\":\"Mudd Manuscript Library\",\"library\":\"Mudd Manuscript Library\",\"location_code\":\"mudd\",\"call_number\":\"AC102\",\"call_number_browse\":\"AC102\",\"dspace\":false}}"
What do you mean by 'catalog zero items'?

The problem seems to be that these directories include single-quote characters

That is confusing a number of operating-system-level tools. I'm not even sure how to rename these.
Googling around, I'm seeing some comments that suggest Unix's ls
tool puts single quotes around names that contain special characters of some sort.
That's really odd. There don't seem to be any special characters anywhere I look at the files -- they are from an older collection. If you rename them in a significant way I just need to know so I can reflect that in the accession record -- removing single quotes that the system added is fine, but if we need to insert underscores for example, just keep me posted so I can record the action.
Not sure if this is helpful--the only characters not in Basic Latin in AC435.EAD.xml are four instances of curly quotes/apostrophes in the top-level scopecontent. (AC436 has none.)
@cwulfman I do think that those directories have spaces, and that ls
is indeed adding the single quotes. Sorry I forgot to mention that — it definitely confused me and was one of the complicating factors that made my first attempt to list the contents of all the directories fail. So assuming we're just dealing with spaces, then properly quoting the paths should work fine, right?
Thanks, @regineheberlein, but this particular issue isn't with the strings in the xml document; it is a matter of directory names (perhaps derived from strings in the xml document). @aberdini , I can't see files -- I can only see listings from ls
(and from the OS X Finder when I mount the archives_bd
volume from diglibdata1.
If either of you is using Windows, could you try renaming one of those directories? Try renaming the folder that appears to be named Logistics.
@escowles , there are other directories whose names contain spaces that do not exhibit this problem. So far I've found no way to properly quote the paths.

@cwulfman Renaming the files is not a workable solution, aside from perhaps inserting underscores for spaces. It is essential for authenticity of our collections that we avoid file renaming wherever possible. I tried to remove the trailing space in the Logistics file name but Windows thinks I haven't changed anything and rejects the suggestion.
Are you able to see the contents of these directories in Windows, @aberdini ?
@cwulfman Yes. Do you need me to look for something?
Thought as much, thanks @cwulfman—just checked the EADs thinking the directory names might have been pulled from the unittitles. Sorry to add noise.
Looks like there were control characters at the ends of those directory names. I logged onto the Isilon and changed the names to remove them.

This app is a tool for singers of Sacred Harp (Shape note) music. It allows singers to search past minutes to see what calls were made by whom and where. The tables are sortable. The app also allows singing secretaries and organizers to easily add, edit and delete minutes in the database using the minutes format that they would use to submit minutes to their parent organizations.
This is an example version of this app which does not use all the available data from past singings due to database limitations on Heroku. For beta testing, any registered user can act as an admin.

Observer
public protocol Observer
Definition of an object for adding KVO and NSNotificationCenter
obeservations to pure Swift classes.
NSObject
s implement a method called methodSignatureForSelector:
which converts from strings to methods. Pure Swift classes do not have this method so cannot inherently perform KVO or observe NSNotificationCenter
posts. Rather than making a Swift class inherit from NSObject
, which introuduces unnecessary features, an Observer
can be retained which performs an arbitrary block on copmletion.
Two default implementations are provided, NotificationObserver
and ObjectObserver
for NSNotificationCenter
observing and keypath observing respectively.

A. GS1 Related
Nothing here for Today!!!
Context
- The government is mulling a new data protection law to protect personal data of citizens
- It will also create an enabling framework to allow public data to be mined effectively
Significance of the move
- It comes amid the debate over security of individuals’ private data, including Aadhaar-linked biometrics
- Owing to the rising number of cyber-crimes in the country, the law becomes even more important
- The working agency: The Ministry of Electronics and Information Technology (MEIT) is working on the new data protection law
Aim of the law
- To ensure that personal data of individuals remain protected and is not misused
- To unlock the data economy
Beneficial data
- A lot of benefits can be derived from the data that is publicly available, by using technology and big data analytics
- The information can be used for the benefit of both individuals and companies
No regulatory body
- Currently, India does not have a separate law for data protection
- There is no body that specifically regulates data privacy
- Nominal data protection law in India in the form of the Reasonable Security Guidelines under Section 43A of the Information Technology Act
- However, it is a toothless law and is never used
What is Consumer Protection Act?
- It was enacted in 2015
- As per the Act, the disclosure of personal information given in confidence is an unfair trade practice
Privacy: A fundamental right
- Privacy is a fundamental human right
- It is recognised as such in the Universal Declaration of Human Rights
- India has ratified the UN’s International Covenant on Civil and Political Rights, which contains an obligation to protect privacy
Category: INTERNATIONAL RELATIONS
1. MoU moots ties with Mauritius Parliament
In news:
- India and Mauritius signed a pact to institutionalize cooperation between the parliaments of the two countries.
- Key point: the relations between the two countries are based on centuries of cultural, linguistic, social and spiritual links that transcend extraneous considerations.
2. Resolve Qatar crisis via constructive talks: India
Context: recent decision by Saudi Arabia and some other countries to break diplomatic relations with Qatar.
Background information: Saudi Arabia, Egypt, the UAE and Bahrain announced that they were cutting diplomatic ties and closing all connectivity links with Qatar, accusing it of supporting terrorism.
In news:
- India asked countries in the Gulf region to resolve the Qatar crisis through constructive dialogue, well-established international principles of mutual respect, sovereignty and non-interference in the internal affairs of other countries.
- GCC countries and India: over eight million Indian expatriates living and working in these countries, India is having vital stakes in the regional peace and stability.
1. Farm think tank’s formula to redress agriculture distress
Context: Ongoing farmers’ agitation in many States
In news:
- The Indian Council of Food and Agriculture (ICFA), an agriculture think tank, has suggested to the Centre to consider its seven-point formula to redress farmers’ distress across the country.
- Some of the major recommendations includes:
- Assuring a decent income for the farmers was vital, and, therefore, the recommendations of the National Commission on Farmers (Swaminathan Commission) on the minimum support prices (MSP) for crops must be fixed at levels of at least 50% more than the weighted average cost of production.
- Establishing easily accessible procurement centres .
- Opening of domestic and international markets for free trade: which could help farmers in realising better profit prospects.
- Operating futures markets across all farm produce:another effective strategy to offset the uncertainties associated with price fluctuations of agricultural commodities. Futures contract route helped farmers decide on trade for a standing crop at a future date at a price agreed before the harvest.
- Establishing a national network of Panchayat level rural growth centres that would create village-level agri-businesses and connect farmers with institutions, banks, technologies and markets.
1. Rhododendrons of eastern Himalayas under threat
In news:
- North-eastern States in India are home to 97% of the Rhododendron species and sub-species in the country.
- New Threat: indiscriminate felling and loss of habitat in the north-eastern States has left many of these beautiful flowering plants vulnerable to extinction.
- Epiphytic species, which grow on other trees or plants, of rhododendrons with limited population are most vulnerable due to loss of the host trees.
- In high altitude areas of Arunachal Pradesh, rhododendrons are routinely cut for firewood by local people, forest fires in the dry seasons in Manipur and Nagaland were threatening the survival of many species.
- The endemic R. wattii from Dzukou hills of Manipur and Nagaland is one of the most critically endangered species in India, with only a few adult trees remaining in their natural habitat.
Key fact:
- Rhododendron (rose tree in Greek) —18 species endemic to India.
- The publication, Rhododendron of North East India: A Pictorial Handbook by scientists Ashiho A. Mao, Sudhansu Sekhar Dash and Paramjit Singh (no need to remember the names ) points out that studies and records suggest that there are 132 taxa (80 species, 25 sub species and 27 varieties) of Rhododendron found in India, of which 129 are found in the north-eastern India alone.
- Only three taxa — Rhododendron arboretum nilagiricum found in south India and Rhododendron colletianum and Rhododendron rawatti from the western Himalayas are not found in the north-east.
- Arunachal Pradesh is home to the highest number with 119 taxa (74 species, 21 sub species and 24 varieties) of the Rhododendron. The small State of Sikkim is home to 42 taxa (25 species, 11 sub-species and six varieties) while 10 taxa are found in Manipur, four in Mizoram and 11 in Nagaland.
- Geographical factors: cold, moist slopes and deep valleys of the eastern Himalayas form a conducive habitat for the luxuriant growth of Rhododendron species. Nowhere in the world, are such unique geographical and ecological formations are found. This is the primary reason for such a diversity of Rhododendron available in the region
- The two famous Rhododendron sanctuaries in the Sikkim State are Barsey Rhododendron Sanctuary in the West district, covering an area of 104 sq.km and Shingba Rhododendron Sanctuary in Yumthang valley of North district with an area of 43 sq.km.
- Rhododendrons are used in local medicines against colds, coughs and chronic bronchitis and diarrhoea.

Bishop of Roseau describes situation in Dominica after unrest as “sad”
by SNO Staff(SNO) – Bishop of the Diocese of Roseau, His Lordship Gabriel Malzaire has described the situation in Dominica as ‘sad.’
His remarks came in light of of civil unrest which rocked the island’s capital on Monday evening.
Speaking at a press conference on Wednesday, Malzaire said the current climate in the country must be corrected.
“To me it is a very sad situation, that’s as much as I would say,” he stated. “It’s a very sad situation and I think we need to work towards correcting it because it is not a nice feature at all.”
Recently, the Prime Minister of Dominica, Roosevelt Skerrit, announced that general election will be held on December 6.
The opposition United Workers Party (UWP) and several civic groups have been calling for electoral reform on the island. They say such reforms will reduce the ruling party’s advantage at the polls.
They have been calling on the Skerrit-led Dominica Labour Party (DLP) administration to clean up the voters’ list, issue voter identification cards, regulate campaign finance and grant equal access to state media resources to all political parties.
For several days protests have been held on the matter but it turned ugly on Monday night when police clashed with protesters who were demanding to see the President.
In the war of words that followed, Skerrit blamed the UWP for the incident while the UWP blamed the police.
At Wednesday’s press conference, Malzaire stated that every Dominican deserves a peaceful election.
“I think everybody deserves a peaceful election and everybody is looking forward to a peaceful election because the loss of Dominica is the loss of absolutely every single person,” he stated.
He said he has invited the Catholic community to fast and pray in preparation for election day and to dispose themselves to something peaceful.
“Anything other than that is not worthy of what we are doing,” the bishop said. “So I would pray that the election would be able to go on as peacefully as possible.”

Ex-UCL winner claims he could’ve been as good as Lionel Messi & Cristiano Ronaldo if he wanted to
Former UEFA Champions League winner and FIFA World Cup finalist Wesley Sneijder has claimed that he could have reached Lionel Messi and Cristiano Ronaldo’s level if he was 100% committed to the sport. He went on to add that ‘it’s not like he couldn’t do it but he didn’t want to’.
The former Netherlands international won the Champions League with Inter before leading his national team to the final of World Cup in 2010. However, the Dutch side lost to Spain and subsequently, Sneijder missed out on the Ballon d’Or as Barcelona trio of Messi, Andres Iniesta and Xavi made the cut with the Argentine winning the prestigious award ultimately.
While in conversation with Fox SportsNL, Sneijder said: “If I would have lived 100% for my sport, I would have joined the list of Cristiano Ronaldo & Messi. I know that. But I didn’t want to, and I don’t regret that. It’s not like I couldn’t do it, I just didn’t want to.”
The 35-year-old even revealed the best player he has ever played with and chose his former Real Madrid teammate Guti.
“Best player I ever played with? Then I choose Guti,” he said. “He impressed me the most. Me and Guti found each other blindly on the pitch, that man was phenomenal. Of course I played with lots of big players but he impressed me the most.”

BLUES BROTHERS 2000 (Universal) Starring: Dan Aykroyd, John Goodman, Joe Morton, J. Evan Bonifant. Screenplay: Dan Aykroyd and John Landis. Producers: Dan Aykroyd, John Landis and Leslie Belzberg. Director: John Landis. MPAA Rating: PG-13 (profanity, violence, adult themes). Running Time: 123 minutes. Reviewed by Scott Renshaw.
For 18 years, THE BLUES BROTHERS has occupied a unique position as perhaps the only action-musical in film history. The adventures of Jake (John Belushi) and Elwood Blues (Dan Aykroyd) on their "mission from God" somehow managed to mix production numbers and car chases into a ridiculous cocktail of over-the-top absurdity and musical showmanship. Much of the film's unlikely success was attributed to the chemistry between Belushi and Aykroyd, but the primary responsibility of the two stars was to maintain a stoic demeanor behind their dark glasses. No, I think THE BLUES BROTHERS worked because it really _was_ like a mission for those involved. Belushi, Aykroyd and director John Landis became proselytizers for soul, prepared to do absolutely anything to bring their musical message to the people. If that meant juxtaposing the Godfather of Soul and vehicular chaos, so be it. It was an insane film powered by the fervor of true believers.
If BLUES BROTHERS 2000 leaves a viewer feeling less than satisfied, it's not necessarily due to the absence of the late Belushi, though John Goodman does frequently seem unsure exactly what to do with himself. The main problem is the absence of a similar focus on the music, replaced by a more cynical attempt to re-create the past. The story is an over-plotted collection of gimmicks, sending Elwood back into the world after nearly two decades in prison to discover that brother Jake and surrogate father Curtis (Cab Calloway in the original film) have both passed on. In a quest to re-connect with some sort of family, Elwood a) seeks out Curtis's illegitimate son Cabel (Joe Morton), an Illinois State Police commander; b) brings a meek bartender named Mack McTeer (Goodman) along to help re-unite the Blues Brothers Band; and c) hooks up with troubled orphan Buster (J. Evan Bonifant), who serves the essential purpose of looking cute in a miniature black suit, hat and shades.
I'm not suggesting that THE BLUES BROTHERS was anybody's idea of a streamlined narrative. It had cops in pursuit, cartoonish hate-mongers, a gun-wielding psycho, switch-wielding nun Sister Mary Stigmata (Kathleen Freeman), Aretha Franklin singing, James Brown preaching, and carnage galore. BLUES BROTHERS 2000, on the other hand, has...well, every one of those things, _plus_ items a-c above. The pointed effort to recreate every situation from the original -- recruiting the band members from new vocations, playing a gig for a crowd expecting a different musical style, etc. -- draws attention to the structure in a way which makes it feel muddled rather than original, tired, rather than inspired. Even Aykroyd's performance draws unnecessary attention to itself, fooling with the notion that Elwood is a three-dimensional character in need of growth. Those who remember him speaking about two dozen words in THE BLUES BROTHERS may be startled to find that prison life has turned him into a loquacious sort given to deconstructing the malevolence of Russian gangstersss or the iconography of the Brothers' distinctive look. They may also be quite disappointed at how the loss of his deadpan reactions takes the edge off the absurdist comedy.
For all its flaws, however, there's almost enough energy in the musical numbers alone to make BLUES BROTHERS 2000 worth watching. In addition to return players Franklin and Brown, the performers include Sam Moore, Wilson Pickett and Eddie Floyd (sharing vocals with teen bluesman Jonny Lang on "634-5789"), and an all-star blues jam for the finale in which spotting the familiar faces is half the fun, and drooling over the epic collection of talent is the other half. Between the high-spirited production numbers and one spectacular hundred-police-car pile-up -- a hilarious non-stop parade of soaring, crashing metal -- there is enough fun to satisfy most viewers, particularly if the familiarity is exactly what they're looking for. It's too bad that the much of the film feels rushed, flattened and processed, like a knock-off sequel cranked out in 18 months instead of 18 years, to be sold with a marketing-friendly abbreviation like BB2K. Even with all the retail destruction and collapsing buildings in THE BLUES BROTHERS, it used to be about the _music_, man.
On the Renshaw scale of 0 to 10 soul men: 5.
