--- layout: post title: My Simple Setup to to Avoid RSI in Emacs excerpt: Introduce some useful tips on how to avoid RSI in Emacs categories: - Emacs tags: - [Emacs, Linux, Keyboard] ---
This is an introduction to my setup to avoid Repeat Strain Injury (RSI) in Emacs. It's very simple.
Here is a list describing how I use Emacs:
ESC
..emacs.d
but I also regularly check some popular
.emacs.d
repos on GitHub. For example, Steve Purcell's emacs.d, Prelude,
and of course, the very popular Spacemacs.I mainly use Emacs on Arch Linux and I have a US layout laptop PC keyboard, which is probably not possible to be replaced by other more ctrl-friendly keyboards.
Only two steps are needed!
This can be achieved by different tools on differnt platforms. I use xcape in
Arch Linux. Just install it from AUR, and use the following script(found in
xcape's README) to use Space
as both SPC
and Ctrl
:
# Map an unused modifier's keysym to the spacebar's keycode and make it a # control modifier. It needs to be an existing key so that emacs won't # spazz out when you press it. Hyper_L is a good candidate. spare_modifier="Hyper_L" xmodmap -e "keycode 65 = $spare_modifier" xmodmap -e "remove mod4 = $spare_modifier" # hyper_l is mod4 by default xmodmap -e "add Control = $spare_modifier" # Map space to an unused keycode (to keep it around for xcape to # use). xmodmap -e "keycode any = space" # Finally use xcape to cause the space bar to generate a space when tapped. xcape -e "$spare_modifier=space"
Now you can now hold down the Space
key to use it as the Ctrl
key. You can
reach the Space
key by your thumb without any problem. On a regular PC, Alt
keys are beside the Space
key, so you can easily press either Ctrl
(remember
it's Space
now!) or Meta
. To produce a real space, just press the Space
key and release it, without holding it.
I Never use Escape
in Emacs, then why on earth do I ever want to swap Caps
Lock
with Escape
? Actually, Escape
key in Emacs is kind of special. You
don't need to hold down the Escape
key while using the key bindings starting
with ESC
, which is very different from Ctrl
and Meta
. I don't know how
Escape
key event is generated in Emacs or in X11, but from a user point of
view, it is quite like other non-modifier keys. You press it down and release
it, one key is generated. This is really nice since we can then use it as the
"leader" key for the Emacs just like the Space
key in Spacemacs.
So first, let's swap Escape
and Caps Lock
so we can easily reach Escape
by
our left pinky. I use setxkbmap
:
setxkbmap -option caps:swapescape
Then remap ESC
to C-c
since it is the standard prefix key reserved for
users:
(define-key key-translation-map (kbd "ESC") (kbd "C-c"))
So why is this useful? If you like the way Spacemacs organizes its key bindings,
you can replace its key bindings with C-c
as the prefix instead of Space
,
since all the single letter key bindings starting with C-c
are reserved for
users. Now let's assume that you bind C-c b b
to behave like SPC b b
, which
is helm-mini
in the case of Spacemacs. You can press the key bindings in
following ways(note ESC
has been remapped to C-c
and swapped with Caps
Lock
so you can easily press it by your left pinky):
ESC
, b
, b
, just like SPC
, b
, b
, one keystroke at a time.ESC
and b
at the same time and then release ESC
and press
b
, just like how you would press C-x b
.ESC
and press b
, b
, just like how you would press C-x
C-x
.
The latter two are valid because ESC
key event is only generated once, but I
would just use the first one because in that case the pinky doesn't have to be
in a stressed state by holding down some key. Just press it and release it. No
extra effort needed. What's more, the Escape
key, after swapped with Caps
Lock
, is almost as easy to be pressed as the Space
key! And there is one
addtional benifit: it is more robust since if you accidentally press your
keyboard in the second or the third way, you can still generate the key sequence
you want! You can now imagine you use Escapemacs
because Escape
is taking
the role of Space
in Spacemacs.
Sorry, I lied. Actually we need an additional step:-). Why? Because we use
Space
as both Space
and Ctrl
. We should carefully think about how to deal
with key bindings that contain Ctrl
and Space
. Of course, you can use the
physical Ctrl
key in this case, then you don't need any addition step. For me,
I rebind those commands to C-c SPC
, and combined with other packages such as
hydra and expand-region.
(defhydra hydra-mark (:body-pre (call-interactively 'set-mark-command) :exit t) "hydra for mark commands" ("SPC" er/expand-region) ("P" er/mark-inside-pairs) ("Q" er/mark-inside-quotes) ("p" er/mark-outside-pairs) ("q" er/mark-outside-quotes) ("d" er/mark-defun) ("c" er/mark-comment) ("." er/mark-text-sentence) ("h" er/mark-text-paragraph) ("w" er/mark-word) ("u" er/mark-url) ("m" er/mark-email) ("s" er/mark-symbol) ("j" (funcall 'set-mark-command t) :exit nil))
key-chord-mode
, avy
and hydra
key-chord-mode
is great. You can press two key strokes quickly to invoke a
command. I have defined many key chords, quite similar as what you can find
on other people's blog on key-chord-mode
, such as xf
to open a file, xs
to save a buffer and bb
to switch buffers. I bind jj
to change to a
simple VI mode which is defined by hydra
, and jk
to avy-goto-word-1
.
avy
is a really awesome package. It helps you quickly navigate in the
visual area. I can't live in Emacs without it. Thanks to abo-abo for creating
so many useful packages(hydra, avy, ace-window, lispy, ace-link, etc.)!
I know someone would always recommend me to use Evil to avoid RSI in Emacs.
Evil is awesome, but I thought for me, it is too heavy-weight. I used to use
Evil very often, and I used Emacs key bindings in insert mode. However, I
found that I stayed in insert mode too long because of my Emacs muscle
memory: all the C-a
, C-e
, M-f
, M-b
kind of commands to navigate the
buffers and of course I also heavily use avy
. Although sometimes I do enjoy
using the VI's hjkl
and other key bindings, I thought I don't really need
the power of Evil. So after hydra
comes out, I used it to define a very
tiny and simple VI mode for myself, and that's just enough for me.
Just don't rebind Caps Lock
to Ctrl
. It harms your pinky.
[ UPDATE 2016-02-25 ] Note: This article describes only part of my settings because I think my own full key remapping settings might be too opinionated(and thus not that helpful). Here describes a little more.

Most modal libraries for Angular are either frustratingly complicated or annoyingly dependent on a ton of external
stuff. Popeye is simple, self-contained, and just "pops up" when you need it to.
Isn't that all you really want, anyways?
Popeye only depends on Angular - no jQuery, Bootstrap, or other libraries required:
npm install angular-popeye
or
bower install angular-popeye
In your HTML:

<link rel="stylesheet" href="path/to/angular-popeye/release/popeye.css" />
In your Angular module dependencies:
var mod = angular.module("MyApp", ["pathgather.popeye"]);
If you want to use the default animations, you'll also need to include ngAnimate, too.
Inject the Popeye service to open a modal and pass along your options:
var modal = Popeye.openModal(...);
The modal object returned is open and flexible. It has resolved,
opened, and closed promises you can use to
listen to the modal state, and exposes the scope and
controller so you can interact with them:
mod.controller("myCtrl", function($scope, Popeye) { $scope.openUserProfile = function(userId) { // Open a modal to show the selected user profile var modal = Popeye.openModal({ templateUrl: "my_modal_template.html", controller: "myModalCtrl as ctrl", resolve: { user: function($http) { return $http.get("/users/" + userId); } } }); // Show a spinner while modal is resolving dependencies $scope.showLoading = true; modal.resolved.then(function() { $scope.showLoading = false; }); // Update user after modal is closed modal.closed.then(function() { $scope.updateUser(); }); }; });
Popeye ships with default CSS that will size your modals, add a blue background, vertically & horizontally center
the modal, and add enter & leave animations. It's easy to customize all of this by adding your own
containerClass and modalClass classes and then
overriding the default rules. Here are a couple of examples:
Zoom!
Small
Boring.
(Check the demo source code to see how these are done.)
Creates a new PopeyeModal with the given options and opens it. This will cause any existing modals to close first before the new modal is resolved and then opened.
Returns the new PopeyeModal instance, which you'll usually want to hold on to.
By default, Popeye uses a containerTemplate that looks like this:

  <-- your modal template is appended here -->

The default styles in popeye.css absolutely position the container to cover the entire window, centers the modal within that container, and positions the close link in the top right. You can, of course, override all of this with your own CSS, or change the containerTemplate to your own template if you prefer.
There are lots of options for opening a modal. If you've used ngRoute routes or ui-router states, you should find these options familiar:
| Option | Details |
|---|---|
| template (string) |
HTML template that will be compiled with the modal scope & controller, then inserted into the modal container |
| templateUrl (string) |
URL to GET the HTML template that will be compiled with the modal scope & controller, then inserted into the modal container. This is overriden by template |
| bodyClass (string) |
Class to add to the body when a modal is open. By default, this is .popeye-modal-open |
| containerClass (string) |
Class to add to the modal container element |
| modalClass (string) |
Class to add to the modal element (which contains your template) |
| scope (object) |
$scope to use for the modal template. By default, a new scope is created off of $rootScope. For convenience, a $close() function is added to the scope that can be used to close the modal |
| controller (string or function) |
$scope to use for the modal template. By default, a new scope is created off of $rootScope |
| resolve (object) |
A map of dependencies which are injected into the controller. If any of them are promises, wait until all are resolved before instantiating the controller. Each value should be a function that returns the dependency (see the ngRoute or ui-router docs for lots of examples of this pattern) |
| locals (object) |
A map of dependencies which are injected into the controller. This is similar to resolve but each value is the dependency itself. This is more to just pass in values that are directly injected to the controller. By default, a modal local is injected to the controller for easy access to the modal instance itself |
| containerTemplate (string) |
HTML template that acts as a container for the modal template. The compiled template is appended to this
container. NOTE: if you override this option, you must include a .popeye-modal element so that Popeye knows where to insert your modal template |
| containerTemplateUrl (string) |
URL to GET the HTML template that will provide a container for the modal template. This is overriden by containerTemplate, which has a default value, so you'll need to set that to null in order to use this option |
| keyboard (boolean) |
Whether or not the ESC key should close the current modal. Default is true. |
| click (boolean) |
Whether or not clicking on the modal container element should close the current modal. Default is true. |
Calls close(value) on the currently active PopeyeModal if there is one.
Returns the current PopeyeModal instance (which is now closing)
Returns whether or not a modal is currently open.
This object handles resolving, opening, and closing modals. A new instance is created on each call to Popeye.openModal. You can use this object to wait on the various promises to do something when the modal is resolved, opened, or closed. Each instance also exposes pretty much all of it's internals which you can use to add whatever logic you need.
Properties include:
| Property | Details |
|---|---|
| close(value) (function) |
Closes the modal and then resolves the closed promise with the given value |
| open (function) |
Opens the modal, after resolving any resolve dependencies first. You typically won't call this directly |
| resolve (function) |
Resolves the modal's resolve dependencies. You typically won't call this directly |
| closed (object) |
Promise that is resolved once the modal is removed from the DOM (note this does not resolve until after any $animate animations are finished). The promise will resolve to the value provided to close(value), if given |
| opened (object) |
Promise that is resolved once the modal is compiled and added to the DOM (note this does not resolve until after any $animate animations are finished) |
| resolved (object) |
Promise that is resolved once all the modal's resolve dependencies are resolved |
| options (object) |
The options that were used for this instance |
| element (object) |
The jQuery/jqLite element of the compiled modal template |
| container (object) |
The jQuery/jqLite element of the compiled modal container template |
The Angular provider for the Popeye service. You can use this provider to configure default options for your application by modifying the defaults property like this:
var myApp = angular.module("myApp", ["pathgather.popeye"]); myApp.config(function(PopeyeProvider) { PopeyeProvider.defaults.containerClass = "my-modal-window"; });

SpaceX adds five dozen more Starlink satellites to burgeoning constellation
SpaceX has now had 50 consecutive successful launches.
by Eric Berger11am ET Update: At the top of its launch window, the Falcon 9 rocket lifted off from Florida and ascended into space. After dropping off its payload, the first stage returned to Earth and landed on a drone ship in the Atlantic Ocean. It marked the first time that SpaceX had flown the same first stage four times. Overall, SpaceX has now had 50 consecutive successful launches.
Meanwhile, 60 Starlink satellites were bound toward low-Earth orbit, and later successfully deployed. Later today, they will begin the process of raising their orbits using on-board thrusters.
Original post: SpaceX has readied a Falcon 9 rocket and a second set of 60 Starlink satellites for a launch on Monday morning. The company is targeting 9:56am ET (14:56 UTC Monday) for liftoff from Space Launch Complex 40 at Cape Canaveral Air Force Station, Florida. Weather conditions appear to be favorable for the launch attempt.
After an "experimental" launch in May of 60 satellites, about 55 of which remain in orbit half a year later, SpaceX has made several modifications to this second batch of Starlink satellites.
"SpaceX has increased spectrum capacity for the end-user through upgrades in design that maximize the use of both Ka and Ku bands," the company stated in a news release. "Additionally, components of each satellite are 100% demisable and will quickly burn up in Earth’s atmosphere at the end of their life cycle—a measure that exceeds all current safety standards."
Starlink is intended to provide low-latency broadband Internet access around the world. By the middle of 2020, after six launches of satellites, the company plans to begin offering service to parts of North America through ground-based user terminals. Global coverage of the "populated world" will follow after the company completes 24 launches. The news release made no comment about efforts to minimize disruption to the night sky—about which astronomers have raised concerns—from a constellation that may one day include more than 10,000 satellites.
SpaceX is just one of several companies, including Amazon and OneWeb, racing to establish space-based Internet services from low-Earth orbit. With a second launch of maturing satellites, SpaceX appears to be leading the field. Although it represents an ambitious financial gamble for the company, the ability to fly 60 satellites at a time on reusable rockets would seem to give it an advantage over other competitors, which do not have such ready access to low-cost, rapid launch capabilities.
To that end, SpaceX will launch Monday's mission on a Falcon 9 rocket first stage that has already flown three times. Moreover, the company will attempt to re-use a payload fairing for the first time. This means that about 80% of the rocket will consist of previously flown materials.
About 8 minutes after the launch, SpaceX will land the Falcon 9’s first stage on the “Of Course I Still Love You” droneship, in the Atlantic Ocean. Then, about 45 minutes after liftoff, SpaceX’s two fairing recovery vessels, “Ms. Tree” and “Ms. Chief,” will attempt to recover the two fairing halves. One hour into the mission, the Starlink satellites are scheduled to be deployed at an initial altitude of 280km.

 There is very little work to do, and the flavours are amazing.
For the cure, cut the head of garlic several times across the width and discard as much of the papery skin as you can.  With a pestle, gently bruise the mixture to release the flavours. Add the chicken wings and massage the cure into them. Cover and refrigerate for at least six hours, overnight if possible.
When ready to cook the chicken, preheat the oven to 150C/300F/Gas 2. Remove the chicken wings from the fridge, wipe off the cure with kitchen paper and pat as dry as possible. Place them in a deep ovenproof pot with a tightly fitting lid, add the cinnamon sticks and enough oil to cover the wings. Cover with the lid and cook in the preheated oven for three hours; there is no need to disturb the dish during this time.
Remove the pot from the oven and leave the chicken to cool slightly in the oil while you make the dusting. The chicken will need one final quick cook in the oven, so if you want to serve them immediately, increase the temperature to 220C/425F/Gas 7.
Blend together the ingredients for the dusting in a food-processor and set aside.
When the chicken wings have cooled, line a dish with a double layer of kitchen paper. With a slotted spoon, remove the chicken wings from the oil (carefully as they will be very tender) and place on the kitchen paper for a few minutes. Carefully transfer the wings to a roasting tin, and roast for 12 minutes or so or until crisp.
Remove the wings from the oven and pat with kitchen paper again. Shake over the dusting mixture and serve, allowing three chicken wings per person. Serve any extra dusting alongside in case you want to add even more!


To insert data into Qi, you must first create a QiType that will enforce what type of data is written to a stream. For this sample, we will be writing events of the WaveData type discussed in the README. Press the button below to create the WaveData QiType.
Now that we have a QiType, we can create a QiStream. Once we create a stream and associate it with a type, we can write data of that type to Qi. Press the button below to create a stream.
Press the button below to write 10 WaveData events to Qi using the InsertValues call.
There are several ways to read data back from Qi. Using GetRangeValues, we can start at index location "1" of our wave data and get the remaining events. We didn't actually write a value with an index of 1, but since we use QiBoundaryType.ExactOrCalculated in our request, we get an interpolated value at index location 1.
| Order | Radians | Tau | Sin | Cos | Tan | Sinh | Cosh | Tanh |
|---|---|---|---|---|---|---|---|---|
| {{event.Order}} | {{event.Radians}} | {{event.Tau}} | {{event.Sin}} | {{event.Cos}} | {{event.Tan}} | {{event.Sinh}} | {{event.Cosh}} | {{event.Tanh}} |
A call to update values will either create or replace an event at the associated index location.  Press Retrieve Events above to see the updated data.
A call to replace values will either create or replace an event at the associated Index location. Press Retrieve Events above to see the replaced data.
The default behavior for a QiStream is Continuous, which will allow interpolation when a requested index isn't present. In order to change this to only give us exact values that were written, we can create a behavior with Discrete mode and update the stream to use it. Once the stream is updated, we should no longer see a value at 1.
QiStreamViews can return a view of the data stored on the server, we can use them to coerce QiStream data of a certain type to be returned as another type. A simple example of this would be to provide a type with the same data shape using different names for each property.
Once we have created our target type we create a QiView specifying a SourceTypeId (our original QiType) and a TargetTypeId.
We can now use this QiView on any GET request and our data will be returned with the structure of the target QiType.
| OrderTarget | RadiansTarget | TauTarget | SinTarget | CosTarget | TanTarget | SinhTarget | CoshTarget | TanhTarget |
|---|---|---|---|---|---|---|---|---|
| {{event.OrderTarget}} | {{event.RadiansTarget}} | {{event.TauTarget}} | {{event.SinTarget}} | {{event.CosTarget}} | {{event.TanTarget}} | {{event.SinhTarget}} | {{event.CoshTarget}} | {{event.TanhTarget}} |
We can also specify target types that have different shapes and data types, in the simple example above Qi was able to perform the mapping automatically. To make more complex changes we will need to specify the mappings explicitly. For this we add a QiViewProperty mapping the source property to the target property. We will create three QiViewProperties and return Sin, Cos and Tan as though they were integers.
Speficying this QiView on our GET request we see that Qi has only returned values for those Properties that have an explicit mapping.
| OrderTarget | SinInt | CosInt | TanInt |
|---|---|---|---|
| {{event.OrderTarget}} | {{event.SinhInt}} | {{event.CoshInt}} | {{event.TanhInt}} |
Finally, if we are ever curious about the mapping for a specific view we can request its QiViewMap. This will show the relationship between the SourceType and the TargetType.
| SourceTypeId | TargetTypeId | {{viewMap.SourceTypeId}} | {{viewMap.TargetTypeId}} |
|---|
| SourcePropertyId | TargetPropertyId |
|---|---|
| {{prop.SourceId}} | {{prop.TargetId}} |
Let's add some tags and metadata to our stream
| Key | Value |
|---|---|
| Region | {{metadataMap["Region"]}} |
| Country | {{metadataMap["Country"]}} |
| Province | {{metadataMap["Province"]}} |
We can also use our tags to search for streams, let's search for streams tagged with 'periodic':
Press the button below to delete all values from the QiStream, pressing Retrieve Events above should now return an empty array.
Press the button below to delete the types, streams, views and behaviors that this sample has created. Failure to do so could cause conflicts if the sample runs again. Please note that deleting a stream deletes all of the data written to that stream.

public EngineOptions.Builder treatInsecureOriginAsSecure(java.lang.String... origins)
origins
to the white list. These (insecure) origins will be treated
as secure origins.
Each origin passed to this method should be an origin or hostname pattern up to eTLD+1. For example, the list may contain "http://foo.com", "http://foo.com:8000", "*.foo.com", "*.foo.*.bar.com", and "http://*.foo.bar.com", but not "*.co.uk", "*.com", or "test.*.com". Hostname patterns must contain a wildcard somewhere (so "test.com" is not a valid pattern) and wildcards can only replace full components ("test*.foo.com" is not valid).
Has the same effect as adding the --unsafely-treat-insecure-origin-as-secure
switch.
public EngineOptions.Builder addSwitch(java.lang.String commandLineSwitch)
Important For advanced usage only. The library does not support all the possible Chromium switches, so there is no guarantee that the passed switches will work. All the supported switches can be set through the corresponding methods of this builder. Switches added using this method will overwrite the corresponding options configured through the methods of this builder.
For example, if you configure the remote debugging port using the remoteDebuggingPort(int)
method and then add the --remote-debugging-port
switch
using this method, the port from the switch will be used.

Docker Universal Control Plane (UCP), the UI for Docker EE, lets you authorize users to view, edit, and use cluster resources by granting role-based permissions against resource sets.
To authorize access to cluster resources across your organization, UCP administrators might take the following high-level steps:
For an example, see Deploy stateless app with RBAC.
A subject represents a user, team, organization, or service account. A subject can be granted a role that defines permitted operations against one or more resource sets.
Learn to create and configure users and teams.
Roles define what operations can be done by whom. A role is a set of permitted operations against a type of resource, like a container or volume, that’s assigned to a user or team with a grant.
For example, the built-in role, Restricted Control, includes permission to
view and schedule nodes but not to update nodes. A custom DBA role might
include permissions to r-w-x
volumes and secrets.
Most organizations use multiple roles to fine-tune the appropriate access. A given team or user may have different roles provided to them depending on what resource they are accessing.
Learn to define roles with authorized API operations.
To control user access, cluster resources are grouped into Docker Swarm collections or Kubernetes namespaces.
Swarm collections: A collection has a directory-like structure that holds Swarm resources. You can create collections in UCP by defining a directory path and moving resources into it. Also, you can create the path in UCP and use labels in your YAML file to assign application resources to the path. Resource types that users can access in a Swarm collection include containers, networks, nodes, services, secrets, and volumes.
Kubernetes namespaces: A
namespace
is a logical area for a Kubernetes cluster. Kubernetes comes with a default
namespace for your cluster objects, plus two more namespaces for system and
public resources. You can create custom namespaces, but unlike Swarm
collections, namespaces can’t be nested. Resource types that users can
access in a Kubernetes namespace include pods, deployments, network policies,
nodes, services, secrets, and many more.
Together, collections and namespaces are named resource sets. Learn to group and isolate cluster resources.
A grant is made up of subject, role, and resource set.
Grants define which users can access what resources in what way. Grants are effectively Access Control Lists (ACLs), and when grouped together, they provide comprehensive access policies for an entire organization.
Only an administrator can manage grants, subjects, roles, and access to resources.
About administrators
An administrator is a user who creates subjects, groups resources by moving them into collections or namespaces, defines roles by selecting allowable operations, and applies grants to users and teams.

Intro
This series of posts cover how to migrate DbSNP’s newly downloadable JSON files into a slimmed-down, relational database, containing population frequency data, associated pubmed IDs, and clinvar data for each SNP in the database.
The entire codebase of this walkthrough is available here on github. I’ve also sprinkled in
Github Links
above all code snippets, to navigate to each corresponding line & file.
Moving forward, NCBI plans to store 1 JSON file per chromosome, and these files can be found here. The total size of this JSON payload is a whopping 104GB of gzipped data.
The uncompressed size of chromosome 1’s file is 162GB, with the compressed size being 8GB. Using this compression ratio (1:20) as a rule-of-thumb, the uncompressed size of the entire dataset is 2.1TB…that’s a lot of data to process and warehouse. Let’s begin with step 1: downloading refsnp_chr1.json.gz
as our case study.
I gave a lightning talk at PyCon2018 about a live, deployed application of this database: The Snip API. You can easily turn your 23&Me Raw Data into insights from DbSNP using this (free) API; the client is found here on github.
Downloading the file
In a perfect, simpler world, the following few LOC would download our 1st file:
import ftplib
dbnsp_filename = "refsnp-chr1.json.gz"
with open(dbsnp_filename.replace(".gz", ""), "wb") as fp:
ftp = ftplib.FTP("ftp.ncbi.nlm.nih.gov")
ftp.login()
ftp.cwd("snp/.redesign/latest_release/JSON")
ftp.retrbinary("RETR " + dbsnp_filename, fp.write, 1024)
ftp.quit()
Unfortunately, the combination of the FTP
protocal, large file download size and network latency create a perfect storm for server side & client side timeouts. Running the above code will lead to server side (or client side) timeout, and eventually the download will come to a halt.
Kudos to this excellent stackoverflow answer for a graceful solution to avoid FTP downloads timing out. We just send simple “NOOP” commands, equivalent to a ‘PING’, from a separate thread, to keep our connection alive:
import ftplib
dbsnp_filename = "refsnp-chr1.json.gz"
with open(dbsnp_filename, "wb") as fp:
ftp = ftplib.FTP("ftp.ncbi.nlm.nih.gov")
ftp.login()
ftp.cwd("snp/.redesign/latest_release/JSON")
size_gb = round(ftp.size(dbsnp_filename) / (1024**3), 2)
print(f"Filesize: {size_gb} GB")
sock = None
while not sock: # Try to open the socket conn w/ server
print("Trying to establish FTP conn")
sock = ftp.transfercmd(f"RETR {dbsnp_filename}")
time.sleep(5)
def download():
transferred, blocks = 0, 0
while True:
byte_chunk = sock.recv(1024*1024*8)
if not byte_chunk:
break
blocks += 1
transferred += len(byte_chunk)
transferred_mb = round(transferred / 1024 / 1024, 2)
if blocks % 1000 == 0:
print(f"Transferred {transferred_mb}MB / "
f"{size_gb * 1024}MB")
fp.write(byte_chunk)
sock.close()
fp.close()
t = threading.Thread(target=download)
t.start()
while t.is_alive():
t.join(60)
ftp.voidcmd("NOOP")
For those wondering, on a shoddy cafe WiFi, downloading refsnp-chr1.json.gz takes about 48 minutes, which was insigificantly less than the time it takes to download the file in Google Chrome (50 minutes). Make sure you aren’t on shoddy cafe WiFi, times 23…
We now have the file refsnp-chr1.json.gz
in our working directory, which holds a JSON object per RefSNP on each line. We want to extract a small subset of the ~200GB of data stored in this file, and insert it into a Relational Database. Let’s define our schema:
Defining our Relational Database Schema
Rather than writing an unmaintanable mess of SQL DDL statements, I opt to use SQLAlchemy’s core library for defining our database schema (i.e. the tables). It’s a powerful, well-maintained library, producing code that is far more maintainable than free-form SQL text. Here are the models representing tables to insert our data into:
# coding: utf-8
import os
from sqlalchemy import (
BigInteger, Integer, Text, String,
ForeignKey, Column, create_engine,
ForeignKeyConstraint)
from sqlalchemy.dialects.postgresql import ARRAY
from sqlalchemy.ext.declarative import declarative_base, declared_attr
Base = declarative_base()
metadata = Base.metadata
engine = create_engine(os.environ["SNIP_DB_URL"])
metadata.bind = engine
class RefSnpAllele(Base):
__tablename__ = 'ref_snp_alleles'
ins_seq = Column(Text, index=True)
del_seq = Column(Text, index=True)
position = Column(BigInteger)
chromosome = Column(String(2))
gene_locii = Column(ARRAY(Text, dimensions=1))
ref_snp_allele_idx = Column(Integer, primary_key=True)
ref_snp_id = Column(Integer, primary_key=True)
class RefSnpAlleleRelative(object):
__tablename__ = 'ref_snp_allele_relative'
id = Column(Integer, primary_key=True)
ref_snp_allele_idx = Column(index=True)
ref_snp_id = Column(index=True)
@declared_attr
def __table_args__(cls):
return (ForeignKeyConstraint(
[cls.ref_snp_id, cls.ref_snp_allele_idx],
[RefSnpAllele.ref_snp_id, RefSnpAllele.ref_snp_allele_idx]), {})
class RefSnpAlleleFrequencyStudy(RefSnpAlleleRelative, Base):
__tablename__ = 'ref_snp_allele_freq_studies'
name = Column(Text)
allele_count = Column(Integer)
total_count = Column(Integer)
class RefSnpClinicalDisease(RefSnpAlleleRelative, Base):
__tablename__ = 'ref_snp_allele_clin_diseases'
disease_name_csv = Column(Text)
clinical_significance_csv = Column(Text)
citation_list = Column(ARRAY(Integer, dimensions=1))
Note: We’re using Inheritance to DRY (don’t repeat yourself) out the
ref_snp_allele_clin_diseases
andref_snp_allele_freq_studies
model definitions. Avoiding small redundancies like these allow for more malleable code, and less opportunity for bugs down the road.
To create these tables, I assume we’ve already created a local PostgreSQL database. Creating and configuring this database is outside the scope of this post, but if on a Mac, you can start by installing PostgreSQL with:
brew install postgresql
…and then reading the quick docs here. There is plenty of documentation on configuring these easily.
Next, to create our tables we leverage SQLAlchemy’s create_all()
method, and some quick SQL statements in the following snippet:
def init_db(database_name):
# Connect to 'postgres' admin DB, and drop the DB named 'database_name'
os.system(f"echo 'DROP DATABASE {database_name};"
f"CREATE DATABASE {database_name};'"
" | psql postgres")
metadata.create_all()
You can now connect to the PostgreSQL database and view the schema:
(env) SeanH@foo:~/snip_warehouse/snip_warehouse$ psql -U SeanH snip
psql (10.3)
Type "help" for help.
snip=# \dt
List of relations
Schema | Name | Type | Owner
--------+------------------------------+-------+-------
public | ref_snp_allele_clin_diseases | table | SeanH
public | ref_snp_allele_freq_studies | table | SeanH
public | ref_snp_alleles | table | SeanH
Defining DTOs (Data Transfer Objects)
Let’s take a quick tangent, and talk about DTOs, Python dicts
and namedtuples
.
It’s very easy to use Dicts
in Python. Consequently, it’s very easy to abuse them. When passing data between functions in a non-trivial application, PLEASE take the time to define an explicit type, like a namedtuple
, rather than abusing a dict
. You will thank yourself months down the road…
Let’s define a series of Data Transfer Object types
, using the collections.namedtuple
datatype, to provide naming consistencies, strict(er) function interfaces, immutability and readability:
# DTO's
RefSnpCopyFromData = namedtuple("RefSnpCopyFromData", [
"ref_snp_alleles",
"ref_snp_allele_freq_studies",
"ref_snp_allele_clin_diseases"])
RefSnpAllele = namedtuple("RefSnpAllele", [
'ins_seq', 'del_seq', 'position', 'chromosome',
'ref_snp_allele_idx', 'ref_snp_id', 'gene_locii'])
RefSnpAlleleFreqStudy = namedtuple("RefSnpAlleleFreqStudy", [
'name', 'allele_count', 'total_count', 'ref_snp_allele_idx',
'ref_snp_id'])
RefSnpAlleleClinDisease = namedtuple("RefSnpAlleleClinDisease", [
'disease_name_csv', 'clinical_significance_csv', 'citation_list',
'ref_snp_allele_idx', 'ref_snp_id'])
We will use these types in part II of our series to keep ourselves sane.
Parsing the JSON Data
As previously mentioned, each line of our refsnp-chr1.json.gz
file contains a JSON object, representing a RefSNP.
Each RefSNP JSON object holds all of the Alleles of the RefSNP in question, usually a single-nucleotide variation (i.e. a G
is replaced with a C
). Our goal is to grab the frequency of each allele, and the clinically significant diseases that are influenced by the allele.
Uncompressed, the 200GB file is too big to load into memory. We turn to iterators
to help us decompress and stream the file contents through our parser.

REDIFF(1) Man pages REDIFF(1) NAME rediff, editdiff - fix offsets and counts of a hand-edited diff SYNOPSIS rediff ORIGINAL EDITED rediff EDITED rediff {[--help] | [--version]} editdiff FILE editdiff {[--help] | [--version]} DESCRIPTION You can use rediff to correct a hand-edited unified diff. Take a copy of the diff you want to edit, and edit it without changing any offsets or counts (the lines that begin “@@”). Then run rediff, telling it the name of the original diff file and the name of the one you have edited, and it will output the edited diff file but with corrected offsets and counts.  The types of changes that are currently handled are: · Modifying the text of any file content line (of course). · Adding new line insertions or deletions. · Adding, changing or removing context lines. Lines at the context horizon are dealt with by adjusting the offset and/or count. · Adding a single hunk (@@-prefixed section). · Removing multiple hunk (@@-prefixed sections). Alternatively, if only one argument is provided, it is taken to be the edited file and the counts and offsets are adjusted as appropriate. Some assumptions are made when used in this mode. See recountdiff(1) for more information. OPTIONS --help Display a short usage message. --version Display the version number of rediff.

In building application software packages, a programmer often has to
deal with a number of libraries, each of which can use a different
error-reporting mechanism. Sometimes one of two values is returned,
indicating simply SUCCESS or FAILURE, with no description of errors
encountered. Sometimes it is an index into a table of text strings,
where the name of the table used is dependent on the library being
used when the error is generated; since each table starts numbering at
0 or 1, additional information as to the source of the error code is
needed to determine which table to look at. Sometimes no text messages are
supplied at all, and the programmer must supply them at any point at which
he may wish to report error conditions.
Often, a global variable is assigned some value describing the error, but
the programmer has to know in each case whether to look at errno
,
h_errno
, the return value from hes_err()
, or whatever other
variables or routines are specified.
And what happens if something
in the procedure of
examining or reporting the error changes the same variable?
The package we have developed is an attempt to present a common error-handling mechanism to manipulate the most common form of error code in a fashion that does not have the problems listed above.
A list of up to 256 text messages is supplied to a translator we have written, along with the three- to four-character “name” of the error table. The library using this error table need only call a routine generated from this error-table source to make the table “known” to the com_err library, and any error code the library generates can be converted to the corresponding error message. There is also a default format for error codes accidentally returned before making the table known, which is of the form ‘unknown code foo 32’, where ‘foo’ would be the name of the table.

January 31th, 2020
When I started college, I was really confident about everything that I was going to do. It only took one week to lose all of it. However, I wouldn’t call this journey as bad as the first semester because it has taught me many values. I always believed I was really good at time-management, but it only took three weeks of college to realize that I am bad at it. It was not just time management I had to change a lot; I also had to change my study techniques and the way I write. I had to stop procrastinating English papers. Basically, I had to reinvent myself. UIC was my dream school, and I had to prove myself here. There are some ups and downs, but never let yourself stay down. Here are a few things I learned during my first semester.
Go to your professors’ office hours. It is really important to go and talk to them. If you have any questions, they can explain it very clearly and they will get to know you very well, which will be useful for future letters of recommendation or for research opportunities.
Talk to your TA’s and LA’s. It might be really hard for you to go to your professors office hours sometimes due to time conflicts. TA’s and LA’s are the next go-to people. They will help you with any questions you have. They might even help with your projects and lab by looking into them more often because they only teach a few people compared to professors.
Make friends and join clubs. College is not just about studying, it is about exploring yourself and making genuine friendships. Those GPA’s and projects will never come to support in your downtime, make good friends and join clubs with them, so you can learn something new and spend time with your favorite people at the same time.
Go to Career Fairs. It is very important for you to go to them during your semester of college because you will get the experience for your next fairs.
Use all of the student benefits. The best thing about a college student are the discounts, you can get free prime for six months and for UIC students, we get CTA – UPASS (Unlimited rides during the semester). Try exploring the city, learn new things, and enjoy all the discounts.
Everyone has their own experiences during college, so enjoy every moment of it.  Make it memorable, insightful, colorful and keep exploring.
