Please help us welcome our next curator Darryl Takudzwa Griffiths. @BlaqNinja completed his Bachelors Degree in Computer Engineering at DUT, graduated in 2011. Due to struggling to find suitable employment he went on to study multiple certificates from bodies such as Microsoft.
He has certificates in N+ (Computer Networking), A+ (Computer Technician & Technical Support), Certified Ethical Hacking V7 (CEH v7), Offensive Security Certified Professional (OSCP). Sadly even with these, he could not secure his desired post so in 2016 he moved to USA.
Darryl was able to secure a job in a corporation that owns casinos as a system analyst & security architect. Within the same year he embarked on a Masters degree in Robotics & Artificial Intelligence Engineering. In 2017 he resigned from his post and started his own company...

I have spent the summer reading about how math & Big Data shape our understanding of the world. To my surprise, it has affirmed the importance of the humanities. Behind the shiny facade of #BigData lies a series of social judgments made by human beings.

A thread w/ citations.
The field of statistics is full of subjective judgments, such as p < .05 being the threshold for significance, or the selection of variables (@JSEllenberg). These are, as @mathbabedotorg puts it, “opinions embedded in models.” But we lose site of this in popular discourse. 2/9
The judgments made my mathematicians and data scientists are no more capital-T True than those made by activists, artists, journalists, etc. The difference is that mathematical judgments can be embedded in code — distilled to 1s and 0s — and scaled to infinity. @rushkoff 3/9

Acabo de leer el Plan #EspanaDigital2025. Me parece tan ingenuo y etéreo para abordar el momento actual que creo que lo único que garantiza es que en 5 años tendremos los mismos problemas (o mayores) con la #tecnología para ser competitivos. Abro hilo. mineco.gob.es/portal/site/mi…
El plan se centra en varias lineas estratégicas que serían aplicables hoy pero también en 2000, 2010 o 2015. Insiste en mantras "atemporales" asociados ingenuamente a la digitalización y creación de riqueza digital pero que ignoran el contexto. Están fuera del timing real.
Muchas de ellas se centran en la infraestructura (#5G, derecho a la cobertura con 100Mbps, etc). Todo ello es muy positivo, pero no deja ser un MEDIO, no un FIN. A no ser que seas una #Telco. Es necesario y positivo, pero no nos hace más competitivos, solo mejores consumidores.

@AWeissmann_ Since we're talking about Stone, and Facebook just shut down one of his social-media networks over there, perhaps it's time to discuss what the @FBI has known about how vulnerable they are since 1/2/20.

Also of interest to @GCHQ, @csiscanada @AIVD @CyberGovAU.

@AWeissmann_ @FBI @GCHQ @csiscanada @AIVD @CyberGovAU @ericgarland Let's start with the original 1/2/20 message.

With apologies for the length of the following, and the unpolished prose (it's the second of four sent over four days, and not remotely the longest)...

Mucho se habla sobre #China como "Faro" de todo ecosistema #Fintech, pero poco sobre su #Regulación el rol del Gobierno chino.

Esta tendencia a omitir al Regulador en el desarrollo del ecosistema #fintech en #China está escudada en que "son un Estado Socialista"

Abro hilo Image
1/ Vengo leyendo mucho sobre el desarrollo de este ecosistema y, principalmente, cómo el Estado se paró frente a gigantes como #Tencent, #Alibaba o #Baidu.

¿Acaso podemos ignorar que hoy #China es el ÚNICO país en todo el mundo con empresas que compiten con #Facebook o #Google?
2/ Sin duda esto tuvo un costo en términos de libertades y demás pero, siendo pragmáticos: lograron ser el ÚNICO país que no transfiere diariamente valor a mansalva a los gigantes #tech de occidente.

(es más, podríamos decir que cada vez más la ecuación es a la inversa)

Had the pleasure of discussing with leading #tech activists on the use of #BigData in #elections in #Africa & the implications for #democracy. With elections in #Guinea #CôtedIvoire #Niger #Burkina #Ghana, the issue is high on the agenda! Thx @Info_Activism! Key resources below.
Think #BigData is not being harnessed for political influence in #WestAfrica? Read @simonallison's article on the use of data in the 2019 presidential #election in #Senegal and think again!

For a deep (and chilling) dive into data-driven campaigning, what it means, how it works, the companies behind it and the services they offer (psychometric profiling, robotcalls, geotracking, etc.), read @Info_Activism's excellent report: tacticaltech.org/#/news/persona…

S Schnorr @schnorrax & A Crittenden @an_crittenden presented an impressive approach to the ethics of science & field work that embodies our motto #HometoTheorythatMatters. Thread below summarizes messages important for anyone working with vulnerable populations! #KLIColloquium
The push across scientific disciplines to collect biological samples outside of #WEIRD societies (western, educated, industrialized, rich, and democratic) has led to an increase in research teams collecting bio-specimen data from an ever-expanding global participant pool. /1
Many of the most sampled populations are from low income countries in the #GlobalSouth – many are Indigenous and marginalized. It is the responsibility of the scientist(s) to acknowledge this and communicate the benefits of their work (or lack thereof) to the community. /2

في حديثي اليوم (ال #ثريد ) سأكمل عن #BigData البيانات الضخمة من ناحية (برمجية)
وسأركز على هادوب Hadoop و سبارك Spark
للحاجة الماسة لتعلم مثل هذه الأدوات الهامة
2.
في حديثي السابق تكلمت عن البرمجة باستخدام MapReduce
وهي أساس لعملاق البيانات Hadoop
وسأتحدث اليوم عن Spark
برمجيآ.. وهو الأكثر استخدامآ نظرآ للسرعة العالية High Performance
تقريبآ 100 مرة مقارنة ب Hadoop (MapReduce)
كما هو مرفق
3.
ماهو Spark
*عبارة عن بيئة مصممة لتحليل ومعالجة البيانات الضخمة بشكل سريع جدآ
يكتب بلغات مثل Python , Java, Scala
يمكن أن يعمل Patch
بمعنى بيانات مخرنة
او Streaming
بمعنى تحليل مباشر لبيانات جارية
*يمكن استخدامه كبيئة فرديه Stand Alone
أو Cluster Mode
بالنظم الموزعه وهو الأشهر

Much debate on #SciComm. Little formal guidance exists. Those on academic committees that oversee ethics & professionalism are unfamiliar with social media. And now we are in a crisis and #pandemic of many levels. #publichealth very different from industry (1st vs rest).
In #publichealth one, the 1st points are be first & be right

There is an inherent tension between these two

With disrupted public health coordination, like cutting off from WHO, changing guidance from CDC (masks only for clinicians, no everyone wear them) how to be accurate?
In comparison, industry guidance #SoMe guidance. Industry has a lot more experience with this and uses it for marketing, market share, customer outreach, customer brand recognition, brand management. The focus is prestige, optics, reputation - there are monetizable traits.

#ViolencesPolicieres & #BigData
[THREAD] traduit du thread de @samswey
Voici ce que nous savons sur les #ViolencesPolicières, en se basant sur les données collectées ces dernières années.
Lien originel :
Malgré la réticence du gouvernement américain à suivre la violence policière, nous avons maintenant des données complètes sur les meurtres commis par la #police via WaPo, mappingpoliceviolence.org & fatalencounters.org.
Bien que nous ne disposions pas de suffisamment de données sur la violence non mortelle, nous pouvons apprendre beaucoup, des données dont nous disposons...

In addition to not addressing confounding by indication, adjusting for the wrong indicators of severity, not accounting for clustering, a supplemental table that appears to have fitted data, the Australian death numbers don’t add up: bit.ly/2TKQmnA. @walidgellad
We also note that the North American hospitalized case numbers exceed publicly reported cases by a log when considering Canada is reporting only 4K, and we estimate 60-100k in the U.S. by 4/13. They quoted 60k from only 550 hospitals: bit.ly/2yJlBIw @dvgbiostat
The @WHO should not have stopped Soldiarity based on this study. bit.ly/2ZHGChP, well-done observational study which performed chart review and adjusted for disease severity via multiple lab/vital signs, did show such a large signal for mortality.

Esta mañana he estado hablando con los alumnos de @MaristasHuelva sobre Bioinformática, el grado que tenemos en la @_usj_, y del doble grado con @FarmaciaUSJ
Les he puesto ejemplos basados en la #Covid_19, así que reaprovecho lo que les he contado para hacer un hilo aquí.
No voy a entrar tanto al cómo se hacen estas cosas, me quedaré en las diferentes aplicaciones, pero ya os imagináis que detrás de todas ellas están muchas de las tecnologías de moda: #IA, #MachineLearning, #BigData, etc. Y otras que no están tan de moda pero que ayudan mucho.
El primer ejemplo que les he puesto ha sido la web de @nextstrain, donde están analizando los datos genómicos que están publicados del virus y estudian como se propaga por el mundo y cómo muta

The problem with #data and being #datadriven and the supposed #bigdata revolution is partially about skills (people lack them) but also about who gets to "own" data inside a company --- >
What's generally happening at places out in the ether:

Step 1: Data is important and should be a competitive advantage for companies.

Step 2: Increasingly, companies have realized that.
Step 3: They’ve tried to “pivot” their business models and shift their hiring processes to be in line with this.

Step 4: Some are seeing results, but most are just gathering data and seemingly unsure what to do with it.

Data is the new buzz word and it is made its way into the Ag sector,helping farmers make smart decisions in order to increase productivity.
Here are some of the benefits of data science

Data Science grants the farmer access to databases collected from examining the weather in
order to come to conclusions that would improve productivity.

Also in gathering data from the soil like uptake rate, land type etc, recommendations can be made as regards the optimal need of the soil for certain nutrients.

In modern agriculture, advanced algorithms are used to
identify the patterns and behavior of nature that helps in forecasting the invasion of pests and the spread of microscopic diseases.

@AcademieAgri @Agreenium Philippe Stoop, membre de l'@AcademieAgri et directeur Recherche et Innovation @ITK_web Introduit les controverses sur les produits utilisés dans l'agriculture (pesticides, fongicides, aliments ultra-transformés), qui alimentent le discrédit des agences sanitaires. #NoFakeScience
@AcademieAgri @Agreenium Étudions : Pourquoi il est normal et légitime qu'il y ait des avis différents parmi les scientifiques sur les produits utilisés dans l' #agriculture, notamment en fonction des #données : sources, les notions de risque VS danger.

1/7. So, there is a BIG paper out (not yet peer-reviewed) out looking at the factors associated with #COVID19-related hospital death. Starting with health records of 17 mil UK NHS patients, they studied >5.5K COVID deaths. Graph summarises factors associated with risk of death. Image
2/7. Read the full pre-print by @bengoldacre and others here: medrxiv.org/content/10.110…
3/7. Interpreting the graph: A 'hazard ratio' of 1 (along dotted red line) has been set by a reference group under each heading e.g. never having smoked. Dots to the right of the red line are indicating higher risk than the reference group and dots to the left, lower risk.
