### Correct use of "rid of"

From what I understood, "rid of" is used when I want to express that particular object will be disposed of something. "Get rid of something," on the other hand, does not specify the object. According to the aforementioned, I found few examples that I do not understand:

Need to rid of this yeast infection fast? (Should not this be "get rid of.."?)

He will rid of it. (Is that correct? It is neither "get rid" nor "rid something of something.")

I found both of these examples on the Internet; it can be easily informal. I would just like to know whether I am right here.

### Decomposing certain elements in ${_2\pi_*^s}$

At the prime $p=2$, for specific values of $i,j>0$, Lin has constructed certain elements in ${_2\pi_{2^{i+1}+2^{j+1}}^s}$ that are detected by $h_2(h_{i+1}h_j^2+h_i^2h_{j+1})$ in the Adams spectral sequence. For $r=2^i+2^j$, such an element is constructed as a composition of maps $$S^{2r}\longrightarrow\Sigma^rB(r/2)\longrightarrow S^0$$ where $B(n)$ is the $n$-th Brown-Gitler spectrum. We know that when $n$ is an odd number, $B(n)$ is realised as a space after finite number of suspensions. I do not know of anything like this for the case of $n$ being even. What I am interested in is either

(i) a factorisation of the map on left, i.e. $S^r\to B(r/2)$, through suspension spectrum of a finite stable complex, i.e. suspension spectrum of a (de)suspension of a space.

(ii) a factorisation of the map on right, i.e. $\Sigma^rB(r/2)\to S^0$, through suspension spectrum of a finite stable complex, i.e. suspension spectrum of a (de)suspension of a space.

(iii) another construction of the map $S^{2r}\to S^0$ above that does factorise through suspension spectrum of a finite stable complex. Note that if we remove the condition of being a finite complex, then we have the Kahn-Priddy theorem.

If such a construction exists, then I will appreciate any reference to it.

Thanks!

Edit I later on realised that the spectra $B(r)$ can be obtained from Snaith splitting for $\Omega^2S^3$. But, I was not sure if this is for the prime $p=2$. Now, I have found references to this in papers of Ralph Cohen, as well as papers of Fred Cohen, Don Davis, Paul Goerss and Mark Mahowald. Still, any comment on any of the above questions would be very helpful.

### how to prevent TextWrangler to highlight syntax on .txt files?

It becomes really annoying when typing an apostrophe.

### How to create a shortcut (a button) for "Make this the only selectable layer" in Python 2.6?

I'm trying to create a script in Python 2.6 to make a button or a keyboard shortcut for "Make This The Only Selectable Layer". I came across the following VBA scripts on the net, but the problem is it's not working in ArcGIS 10. Can anyone help me with a Python script to do that?

Public Sub MakeLayerSelectable_Click()

Dim pMxDocument As IMxDocument
Dim pMap As IMap
Dim pEnumLayer As IEnumLayer
Dim pLayer As ILayer
Dim pId As New UID
Dim pFLayer As IFeatureLayer

Set pMxDocument = Application.Document
Set pMap = pMxDocument.FocusMap
pId = "{6CA416B1-E160-11D2-9F4E-00C04F6BC78E}"
Set pEnumLayer = pMap.Layers(pId, True)
pEnumLayer.Reset
Set pLayer = pEnumLayer.Next
Do While Not pLayer Is Nothing
If TypeOf pLayer Is IFeatureLayer Then
Set pFLayer = pLayer
pFLayer.Selectable = False
End If
Set pLayer = pEnumLayer.Next
Loop

Set pLayer = pMxDocument.SelectedLayer

If TypeOf pLayer Is IFeatureLayer Then
Set pFLayer = pLayer
pFLayer.Selectable = True
End If

End Sub


### How to install compiler tools with opkg on MIPS CPU architecture

I just bought a set top box (digital reciever - Vu+ Solo2) which runs Linux, and would like to compile some C software on it. It uses OPKG as the package manager. I executed

opkg update


and:

root@vusolo2:~# opkg install gcc <br/> Unknown package 'gcc'.
Collected errors:
opkg_install_cmd: Cannot install package gcc. <br/>
root@vusolo2:~#


I figured that this is because I do not have the necessary repositories. The files in /etc/opkg/ only point to "feeds/repositories" that are owned by the creators of the Linux image that the receiver is running (Black Hole).

As far as I understood, the repositories need to match the CPU architecture. Here is the output of /proc/cpuinfo:

root@vusolo2:~# cat /proc/cpuinfo
system type : BCM7346B2 STB platform

Now, which repositories should I use to get the following packages:

gcc
make-dev
binutils-dev
libgcc-dev ?

I have done some independent research that I wish to mention in my SOP. The full account of what I have done till has been published as an e-print on arxiv.org. Can I give a hyperlink to this e-print in my SOP?

### Present Perfect vs Present perfect continuous

Could you correct the comments in parentheses, please? Are they right?

1. I have lived in Los Angeles. (A completed action; the person does not live there anymore).

2. I have lived in Los Angeles my whole life. (The person is still living there, or spent her whole life in Los Angeles, but is currently living in another location).

3. I have been living in Los Angeles. (She doesn't live there anymore, but was living there recently, or is still living there).

4. I have been living in Los Angeles my whole life. (The person is still living there or spent her whole life in Los Angeles, but is currently living in another location).

### Need I leave and reenter the Schengen area after my work visa expires to become a tourist?

I am an American citizen living in Poland for 6 months.

I arrived in Poland on March 1, 2016 without a work visa (i.e, on a business trip).The count toward my Schengen days began.

I received my National Long-Stay Work Visa to legally work in Poland on April 7, 2016 at the consulate in Chicago and then returned to Poland on April 10th.

The work visa expires on July 7th. I intend to travel Europe until my scheduled departure on July 31.

My question is as follows: Because I entered the Schengen area on February 1, and received my entry tourist stamp - do I need to exit and reenter the Schengen area on July 7th in order to reestablish myself as a tourist in the Schengen area?

Or, am I allowed to remain in the Schengen area from July 7th until July 31st without exiting and reentering - since I already have my Schengen entry stamp from February 1?

Please note: The Schengen Borders Code states:

Periods of stay authorised under a residence permit or a long-stay visa shall not be taken into account in the calculation of the duration of stay on the territory of the Member States.

### How to enable task locking in Android 5.0 production devices

This StackOverflow question explores how to enable a device owner app, and thus kiosk mode, in the Android L developer preview. As the method requires a userdebug build of Android, rooting the device, and copying an XML file into the root filesystem, it doesn't seem suitable for mass deployment of a single function Android device inside a company.

How are device owner apps going to be installed on production Android L devices?
