Hello,

I tried that before posting the question to the list but I keep getting 
an error such as this even after the map() operation to convert

I am simply invoking the following:

val rddDF:DataFrame = rdd.map(x => Holder(x._1,x._2)).toDF
rddDF.registerTempTable("rddf")

rddDF.schema.mkString(",")

You can share RDDs using Apache Ignite - it is a distributed memory 
grid/cache with tons of additional functionality. The advantage is extra 
resilience (you can mirror caches or just partition them), you can query 
the contents of the caches in standard SQL etc. Since the caches persist 
past the existence of the Spark app, you can share them (obviously). You 
also get read/write through to SQL or NoSQL databases on the back end 
for persistence and loading/dumping caches to secondary storage. It is 
written in Java so very easy to use from Scala/Spark apps.

There is another option in case of RDDs - the Apache Ignite project - a 
memory grid/distributed cache that supports Spark RDDs. The nice thing 
about Ignite is that everything is done automatically for you, you can 
also duplicate caches for resiliency, load caches from disk, partition 
them etc. and you also get automatic spillover to SQL (and NoSQL) 
capable backends via read/write through capabilities. I think there is 
also effort to support dataframes. Ignite supports standard SQL to query 
the caches too.

Hello, thanks for replying!

Below is the function I took out from the code.

def converter(rdd: RDD[(String, JsValue)], param:String): RDD[(String, Int)] = {
  // I am breaking this down for future readability and ease of optimization
  // as a first attempt at solving this problem, I am not concerned with performance
  // and pretty, more with accuracy ;)
  // r1 will be an RDD containing only the "param" method of selection
  val r1:RDD[(String,JsValue)] = rdd.filter(x => (x._2 \ "field1" \ "field2").as[String].replace("\"","") == param.replace("\"",""))
  // r2 will be an RDD of Lists of fields (A1-Z1) with associated counts
  // remapFields returns a List[(String,Int)]
  val r2:RDD[List[(String,Int)]] = r1.map(x => remapFields(x._2 \ "extra"))
  // r3 will be flattened to enable grouping
  val r3:RDD[(String,Int)] = r2.flatMap(x => x)
  // now we can group by entity
  val r4:RDD[(String,Iterable[(String,Int)])] = r3.groupBy(x => x._1)
  // and produce a mapping of entity -> count pairs
  val r5:RDD[(String,Int)] = r4.map(x => (x._1, x._2.map(y => y._2).sum))
  // return the result
  r5
}

If I call on the above function and collectAsMap on the returned
RDD, I get an empty Map(). If I copy/paste this code into the
caller, I get the properly filled in Map.

I am fairly new to Spark and Scala so excuse any inefficiencies - my
priority was to be able to solve the problem in an obvious and
    correct way and worry about making it pretty later.

Currently the user is able to set {{.withKeepBinary()}} for any used 
marshaller. But it obviously causes ClassCastException for non-binary 
marshallers and should be available only for binary marshaller.

Note that withKeepBinary() is just a way to tell a cache not to deserialize
values when doing a get or running an entry processor. The concept of
binary object does not belong solely to caches - you can get an instance of
IgniteBinary interface from Ignite and use binary objects in computations,
for example.

For me there would be more confusion if each cache had a separate
marshaller. What would then happen if you put an instance of BinaryObject
to a cache with JDK marshaller? When marshaller is global, the answer is
simple - BinaryObject is either available or not :)

Hi,

The current version of test is not very clean and it works only because
withKeepBinary() is a noop. The correct version would be to use plain cache
for non-binary-object entry processor and use withKeepBinary for
binary-object entry processor. You can see that EntryProcessor creation is
encapsulated in a separate method testClosure() which is overridden in test
inheritors. The same thing should be done for the cache.


Alexey, thank you for the comment.

On a side note: you do not find it confusing that you can set a 
marshaller on a grid but you get a binary cache from another cache via 
withKeepBinary()?

IGNITE-2693: question about setting BinaryMarshaller on a cache

2016-03-09 Thread Dood


Hello all,

I am working on IGNITE-2693 with Vlad Ozerov's help. I am somewhat of a 
Java newbie so please be gentle ;-)


I am curious about something - after reading the Javadocs and Binary 
Marshaller docs on Ignite's documentation websites, I think that the 
documentation is not very friendly or even somewhat misleading. Or maybe 
it is the design that is puzzling to me :-)


For example, we use withKeepBinary() on a cache instance to get a binary 
cache that utilizes the binary marshaller. But this is not a setting 
that is "settable" on a per cache basis - we do not allow for a 
per-cache method to set a desired marshaller, this seems to be reserved 
for the IgniteConfiguration() interface/implementation(s) 
setMarshaller() method and is a grid-wide setting.


The background to this is that I have "fixed" the withKeepBinary() 
interface to throw an exception if the marshaller used is not binary 
(the ticket explains the reason why we want this). Apparently we 
(silently?) assume a binary marshaller everywhere but in one of the 
unrelated tests in the test suite for some reason an optimized 
marshaller is used and as a result of this (with my new change) these 
tests are failing [1]. I am trying to fix this but in the process I 
realized that you cannot set the marshaller through a 
CacheConfiguration() method (no such thing exists), this has to be done 
at a higher level (the IgniteConfiguration). However, the whole test is 
written to inherit a grid configuration with an optimized marshaller (is 
what it looks like to me)


Am I just horribly confused and missing something very obvious? Thanks!

Igniters,

I would propose to switch back to review-then-commit process. This

There is a reason for this I have in mind. Ignite is a complex 
platform with several big modules. Some of the people may be experts 
in module A while others in module B etc.
If a committer, who is good in module A, makes changes in module B 
merging the changes without a review this can break module's B 
internal functionality that the committer didn't take into account.


My proposal is to introduce a list of maintainers for every Ignite 
module like it's done in Spark [1] and a rule that will require a 
committer to get an approval from a module maintainer before merging 
changes.

Lack of binary mode prevents us from implementing IgniteQueue in .NET

AtomicReference is already implemented, and it works because values

wrapped in GridCacheAtomicReferenceValue. So there is inconsistent

Hello all,

I was wondering if anyone can take a look at the PR I submitted for
IGNITE-1144 [1]. It compiles and I think the code is good but the tests I
submitted are failing - specifically, one test: I am using assertThrows()
to make sure that an exception is thrown if affinityRun() is invoked on a
queue that is not collocated. In the tests I basically set up a queue that
has a configuration that invokes setCollocated(false) and then I invoke an
affinityRun() with an "empty" job. For some reason the tests are failing
with an error that the exception wasn't thrown. However, in this case I
actually think that my test is bad and the PR code is good ;-). Can someone
with more Java experience take a quick look?

That's the million dollar question - I think we should approach the 
Arrow people and get a conversation going. We want to be ahead of the 
curve, not behind it - Arrow seems to be making quite a stir, not to 
mention that it was fast-tracked to mature project status apparently 
solely based on the people/companies involved ;-)

Async and sync ops in IgniteQueue and IgniteSet implementations

2016-02-12 Thread Dood


Hello all,

This may be a very dumb question (and feel free to "reprimand" me ;-) 
but I will ask it anyways.


I am working on https://issues.apache.org/jira/browse/IGNITE-1144 and 
one of the comments on the submitted code was that I marked both methods 
I am implemented as @IgniteAsyncSupported but I never actually provided 
an async implementation. All my methods do is call on methods already 
implemented in IgniteCompute.java (after verifying that the methods are 
called on data structures that are collocated) and my assumption was 
that the methods being called are already implemented in async/sync 
versions. Specifically, these methods are affinityRun() and affinityCall().


Furthermore, I noticed the following comment in IgniteQueue.java, for 
example:

""* All queue operations have synchronous and asynchronous counterparts."".

However, after looking at all the implementations of IgniteQueue 
interface in the code base, I could not find any actual implementations 
of asynchronous calls on any methods of queue or set. Am I just missing 
something really basic?


Thanks!

Re: Async and sync ops in IgniteQueue and IgniteSet implementations

2016-02-12 Thread Dood


Val,

My question was also - if all I am doing is calling affinityRun() and 
affinityCall() that is already implemented elsewhere (just making sure 
it is done on a collocated queue/set) - do I need to do anything special 
looking at IgniteComputeImpl.java it looks like affinityRun()/Call() are 
already implemented in async fashion?)?


Thanks!

On 2/12/2016 1:49 PM, Valentin Kulichenko wrote:

Hi,

First of all, the JavaDoc is incorrect, there are no async counterparts for
queue and set operations in the current API.

The question is - do we need them? I think we should have have them for new
affinityRun and affinityCall methods that you're adding, but I'm not sure
about others.

Does anyone has thoughts on this?

Compiling Ignite against different JDKs

2016-02-11 Thread Dood


Hello all,

I am working on a ticket that is not very difficult, if you are good 
with Idea, Java, Maven etc. I have been a developer in various languages 
but new to Java ;).


I had JDK8 installed and I introduced some changes to the code base that 
cause it to not compile (apparently) against the JDK7. I downloaded JDK7 
and installed it, I went into Project Structure->JDKs in Idea and added 
the version 7 and set it as default for the Ignite project. However, 
every time I try to build the ignite-core module, it complains about 
"invalid source release: 1.8". Clearly I am missing something - but 
what? Are there any instructions anyone can point to for switching JDKs 
in IntelliJ?


Thanks!

Re: affinityRun() and affinityCall() (JIRA ticket)

2016-01-29 Thread Dood


Val,

Before I go on and submit pull requests etc. - would you comment on the 
path I am taking with this? As I said I am not a JAVA developer but I am 
trying to teach myself the language and contribute at the same time ;)


Here are my thoughts on implementing this for the queue 
(GridCacheQueueAdapter.java). I have also declared the following in 
IgniteQueue.java:


@IgniteAsyncSupported
public void affinityRun(IgniteRunnable job) throws IgniteException;

@IgniteAsyncSupported
public  R affinityCall(IgniteCallable job) throws IgniteException;

Here is what is in GridCacheQueueAdapter.java

/** {@inheritDoc} */
public void affinityRun(IgniteRunnable job) {
if (!collocated)
throw new IgniteException("Illegal operation requested on non-collocated 
queue:affinityRun().");


try {
compute.affinityRun(cache.name(),queueKey,job);
}
catch (IgniteException e) {
throw e;
}
}

/** {@inheritDoc} */
public  R affinityCall(IgniteCallable job) {
if (!collocated)
throw new IgniteException("Illegal operation requested on non-collocated 
queue:affinityCall().");


try {
return compute.affinityCall(cache.name(),queueKey,job);
}
catch (IgniteException e) {
throw e;
}
}

I have included the following at the top of the class 
GridCacheQueueAdapter:

private final IgniteCompute compute;

this.compute = cctx.kernalContext().grid().compute();

Let me know what you think!

On 1/27/2016 3:55 PM, Valentin Kulichenko wrote:

Hi,

Both GridCacheQueueAdapter and GridCacheSetImpl have a reference to
GridCacheContext which represents the underlying cache for the data
structure. GridCacheContext.name() will give you the correct cache name
that you can use when calling affinityRun method.

Looking at this ticket, I am guessing that what it needs to do is get the

[Muscle] coolkey or pkcs variant with acrobat reader?

I wanted to be able to sign PDFs instead of having to use windows to do so.
 I use coolkey with firefox and chrome in Linux, but I installed the 686
version for acrobat reader in Fedora 20.

I tried to follow the instructions here, albeit a little different:

But when I try to load /usr/lib/libcoolkeypk11.so
it won't load it and gives an unclear error.

Any ideas?

[Muscle] connection reset/no data returned errors in browser with pcsclite/coolkey

Hello,

I have Fedora 19 on two machines.

I use libcoolkey to use a Common Access Card's certificates to access my
webmail at http://www.foo.bar.gov

However, since upgrading to F19 on machine two, although I am prompted for
pin, etc, and certs show, and I can choose the right cert, I get:

The connection was reset

The connection to the server was reset while the page was loading.

and on a related site, I get:

Unable to load the webpage because the server sent no data.
Error code: ERR_EMPTY_RESPONSE

On machine one, it works fine.  I cannot figure out what the problem is
here.  Same version of pcsc, same version of libcoolkey... on machine 2,
both firefox and chrome have this problem.

Both machines are on the same network.

On machine two, if I open up virtualbox and go to win8, and use CaC there,
I can access the site with IE.

Any site that requires email signature certificate on card has this
problem.  If the site requires digital ID certificate, it still works fine.

That sounds like the old version was caching the pin, and new version is
not, or not caching it correctly.

For PIV cards, (and all newer CAC cards are both) when the signature
key is used to do a crypto
operation, the previous operation to the card must have been a verify i.e.
PIN is sent.

You can run pcscd in debug mode, and watch the commands to the card to get
some more information.

And as a previous responder said, it could be because the *.gov web site
is down...

OK, I seem to have narrowed it down. It's an SCR-331 CaC reader.

Once I tried a different model, it works without a problem.

That being said, I used the SCR-331 for years without an issue. Did pcscd
have an update in the last few months that would have affected support? I
last used the card reader in May and had been using it without incident.

ok I set 3 alarms 2 minutes apart - radio station 1, radio station 2 and
music tone.
It changed from one to the other station with a beep and pause in
between. unfortunately the third alarm using a music tone went on ad

alarm.

I will experiment with some radio stations that don't play, and could
use these as off alarms.

[SlimDevices: Touch] can you set duration of alarms?

2012-08-20 Thread dood


I use the alarms to turn on the SBT as my alarm clock every morning. I
set it to turn on a radio station rather than alarm sound.
Is there any way to get it to turn itself off say after 2 hours? Perhaps
integrate the sleep function?

Wishful thinking: can I get it to change stations at pre-determined
times?

[SlimDevices: Touch] squeezecommander vs squeezebox app

2012-08-11 Thread dood


I've downloaded squeeze commander as an alternative to the Logitech
android app, after reading how much better it is.

I've found that it is not very intuitive. For example I can't figure out
how to change the player. In the settings it shows that it
sees 2 players. On the Logitech app you simply touch the name of the
player and you get a list of players to select.

The Logitech app also has a split screen that allows you to see more.

I don't get how the paid app is better. Am I missing something?

In itunes I can see the NAS and this displays all the songs on it.
However, I cannot drag these songs into the playlists (red circle icon

As I've said these songs from the music library don't show up on the

[SlimDevices: Touch] BBC live does not work through DAC

2012-08-07 Thread dood


I can access internet radio on my SBT as expected. When I go to BBC
iplayer, it plays the recorded programs on the various channels but does
not play the live broadcast.
After assessing variables I discovered that this only happens when the
SBT is connected to my external DAC (an old Wadia12). When I connect the
SBT to my amp via analogue outputs, the BBC live plays fine.

Has anyone else encountered this issue? I suspect it is because my DAC
is several years old, but it would be interesting to see if it happens
on newer DACs, and what the explanation is for this behaviour.

 It can also be a word length problem for the old DAC keep the squeezebox
 volume at 100% and try again

If I remember correctly it is 44.1 and 48. I'll check when I get home
whether it automatically detects the frequency or if I have to manually
select 48kHz. I've only used it with CDs at 44.1kHz.
Will also try the volume setting.

[SlimDevices: Touch] SBT not seeing server

2012-07-19 Thread dood


I have had my SBT for a few weeks now. Unfortunately it only functions
intermittently.

I have a QNAP NAS which store my music files. I have installed LMS on
it.
I have a wifi network at home and the SBT connects to it and there's no
problem getting internet radio.
I have succeeded in accessing my music from the NAS on the SBT, and when
it works it's fine.
If I attach a USB stick it sees it and can play the music on it.

The problems:
1. The SBT sometimes doesn't see the network. After powering on and off,
unplugging and replugging mains, getting to the menu that allows me to
re-input wifi password, I have managed to get it back.
2. Currently it connects to internet, and I am listening to internet
radio. However it does not see the music on my NAS (in fact it doesn't
see the NAS) and tells me to install LMS on my computer. Yet I can see
the music on my laptop and play it on itunes.
3. The squeezebox app on my ipad is erratic. Sometimes it shows my music
and lists internet radio stations. However, at the moment it shows what
song is playing but I can't get back to the main menu.

Anyone able to help please?

update

I went into the QNAP admin page.
Disabled LMS ans re-enabled it.
Went to SBT, switched libraries and it saw my NAS and music.

So the question is why is it losing connection to the NAS?

Another question: How do I create music playlists on my computer that
can be accessed by the SBT from the NAS (ie when computer turned off).
the only playlists I see on the SBT are the radio stations I've added.

 If this is happening when you power up the NAS then it is likely that
 the NAS is too slow on it's bootup and not fully booted when LMS starts.
 You can add a program on your NAS to delay LMS startup.
 
 If the Touch is connected to LMS on the NAS then you navigate away from
 LMS then Touch cannot navigate back to LMS (and you did not turn off
 your NAS in the mean time) then your NAS has a settings issue or
 possibly the NAS has other programs running which require use of the
 same ports as LMS needs.
 
 Playlist creation:  Simply use your computer to remotely log into the
 LMS web UI, there you can create playlists by simply adding  saving
 items to your current playlist.

will have to look into power settings on NAS.

Not sure what you mean by touch navigating away from NAS - do you mean
like in switching libraries to USB?
NAS does have one other program - Twonky media, this is for streaming to
my WDTV live. Curiously when I re-enabled LMS, I noticed that Twonky
media was disabled. I re-enabled it (twonky media) whilst the SBT was
playing music from the NAS and this was not affected.

Will look at the playlists again when back on my home network.
Interestingly I read that you can export itunes playlists and that these
should work on the SBT. I created a test playlist in itunes, then
exported the .xml file to the playlist folder under multimedia in the
NAS, but the touch couldn't see it.

[R] using var from bash in R script

2012-01-04 Thread dood

Dear R users,

This probably a really noob question, but I'm stuck. I'd like to pass some
variables from bash to R as strings. I can successfully pass variables using
commandArgs(), the problem is that I end up with an array. So, for example:

 Args - commandArgs(TRUE)
 Args
[1] one   two   three

Now, it just so happens that one, two, three are names of columns that
I'd like to work with. I'd like to do something like this:

 print(summary(lm(Args[1] ~ Args[2])))

But, this doesn't work. The alternative would be to let bash write a number
of R-scripts and then rm them when done, but that seems like an unnecessary
step. 

Can this be done?

Thanks

To prevent opkg from upgrading the kernel try:

opkg flag hold kernel-2.6.24
opkg flag hold kernel-image-2.6.24

Altho i think you only need to block the kernel-image-2.6.24 After
getting a neo1973 kernel and a bad kernel that wouldnt boot from opkg, i do
all my kernel upgrades with the dfu-util.

 Somewhere along the line I installed the illume package with the

 Also, I see this interesting comment in Default.kbd:
 
 # if the key out is in quotes - q for example, then this key is used for

 # pressed will end the dictionary match (u can disable dictionary

 So, that implies that if I can just get the system to recognize 
 alternate kbd files, I can turn off dictionary matching, which would 
 make me rather happy.
 
 
 Hmmm, waitaminnit, looking at the files in that directory, I don't think 
 they control the standard 2008.08 keyboard.  I'm talking about the one 
 where you flick up/down to shift to other layouts.
 
 Sigh.  I guess I'm still stuck with the irritating keyboard.  What's it

Finally found how to get this one to work... the problem is with python-ecore
package the newest one doesnt even seem to run camp wifi for me anymore.
The version you want to install is from

http://buildhost.automated.it/OM2007.2/packages/armv4t/python-ecore_0.2.1+cvs20080702-r1_armv4t.ipk

If you cant get opkg to install it for you try -force-downgrade, which
doesnt seem to work for me. so i just temporarily removed my
armv4t-feed.conf from /etc/opkg, removed the package, then had opkg update
and typed

opkg install
http://buildhost.automated.it/OM2007.2/packages/armv4t/python-ecore_0.2.1+cvs20080702-r1_armv4t.ipk

This should work, goodluck

Re: Flash ASU

2008-07-29 Thread DooD


Most of these instructions i have pulled off the wiki or from other e-mails,
Do not hold me responsible if you brick your Freerunner while following
them.

Here is what has worked for me so far
First you want to get the newest ASU rootfs from

http://buildhost.openmoko.org/daily/freerunner/

The newest ASU rootfs for now is

http://buildhost.openmoko.org/daily/freerunner/200807/20080722/Openmoko-openmoko-qtopia-x11-image-glibc-ipk-P1-Snapshot-20080722-om-gta02.rootfs.jffs2

After you have downloaded that you will want to go to

http://wiki.openmoko.org/wiki/Flashing_the_Neo_FreeRunner

Following the instructions on the page download the dfu-util to the same
directory as the rootfs.jffs2

http://downloads.openmoko.org/releases/Freerunner/dfu-util

Now you will need to power down your Freerunner and power it into the NOR
uBoot menu for flashing.
(in short: press and hold aux then power)
When the menu has come up attach the Freerunner to your host linux system
via USB.
*note* uBoot menu will not stay on for long, unless you scroll using the aux
button

Now open a terminal on the host linux system, go to the directory of your
dfu-util and rootfs.jffs2,and run the command:
*note* changing the name of the rootfs.jffs2 to whatever you downloaded

./dfu-util -a rootfs -R -D
Openmoko-openmoko-qtopia-x11-image-glibc-ipk-P1-Snapshot-20080722-om-gta02.rootfs.jffs2

Let dfu-util run its magic, then you should be able to boot into the ASU.

-

Now if you installed the 200807022 ASU you will notice some problems, mainly
that there is no keyboard!
What you will need to do now is to opkg update and upgrade.

Assuming your host linux system has internet you will want to follow the
instructions in

http://wiki.openmoko.org/wiki/USB_Networking

On the host linux system commands

ifconfig usb0 192.168.0.200
ssh [EMAIL PROTECTED]

should allow you to connect to the phone.

--

If you do not know how to use the vi editor on the Freerunner you may not be
able to do this next part
Also read the notes before updating your .conf files

Once you have your phone connected to the internet you will want to change
your opkg feeds. Manually you can just goto /etc/opkg and use vi *.conf, or
you can download updated .confs from

http://www.mikeasoft.com/~mike/opkg-asu.tar.gz

On the phone just cd /etc and type wget
http://www.mikeasoft.com/~mike/opkg-asu.tar.gz; followed by tar xzf
opkg-asu* This will extract the *.conf files to /etc/opkg. 

*IMPORTANT NOTE1* If you change the neo1973-feed.conf to
http://downloads.openmoko.org/openmoko-repository/ASU/neo1973, opkg will
download a kernel for the neo1973 onto your freerunner, while it wont stop
the phone from working it may stop the phone from having sound.
*IMPORTANT NOTE2* The newest e-wm and illume packages do not seem to work,
opkg upgrade may stop you from being able to boot into the ASU, tho you can
still connect to it with ssh. For now i would recommend pointing
/etc/opkg/armv4t.conf to http://buildhost.openmoko.org/daily-feed/armv4t and
rerun opkg update before running opkg upgrade.
*IMPORTANT NOTE3* opkg install
http://buildhost.openmoko.org/daily-feed/om-gta02//kernel-image-2.6.24_2.6.24+git25+8533927964761f4e2078ccd8607b90f5acc60b93-r0_om-gta02.ipk
does not seem to flash the kernel correctly and will cause the system to
hang right as you power up your phone. you will need to reflash your kernel
in order to be able to boot again.

---

To get a keyboard working, and hopefully not kill your phone, try installing
the above *.conf files, but before running opkg update or upgrade :

rm /etc/opkg/om-gta02-d*
echo src/gz daily-neo1973 http://buildhost.openmoko.org/daily-feed/neo1973;
 /etc/opkg/neo*
echo src/gz daily-armv4t http://buildhost.openmoko.org/daily-feed/armv4t; 
/etc/opkg/arm*
opkg install
http://downloads.openmoko.org/openmoko-repository/ASU/armv4t/app-restarter_1.0+svn4552-r0_armv4t.ipk

Now run opkg update, followed by opkg upgrade. Reboot your Freerunner and so
long as you boot into the ASU you should be able to use the keyboard in
Qtopia apps
 
--

If you are going to be installing GTK apps, such as opkg install
openmoko-terminal2 you will want to be able to use the keyboard, either you
can have the keyboard automatically popup by installing
matchbox-keyboard-im*.ipk, or you can install a theme with the qwerty
button.

To have the keyboard automagically popup

cd /tmp
mkdir matchbox-keyboard
cd matchbox-keyboard
wget http://www.ginguppin.de/files/keyboard-ipk.tar.bz2
tar -jxf keyboard-ipk.tar.bz2
opkg install matchbox-keyboard-im*.ipk
cd ..
rm -rf matchbox-keyboard

*note* it will extract 3 files, you only need to install
matchbox-keyboard-im*.ipk The other packages may completely replace the
keyboard...

I'm trying to figure out how to parse an xml document, and convert it into
html...
i know how to parse in simple xml stuff for example
easyeasy/easy is pretty easy to parse in, and i know how to code that,
but when you start adding flags that i'm going to need variables for,
example easy does=1 it=2easy/easy is not so easy.
